In the event Client has not made payments on the due date set forth on the Project Specification, Consultant shall have the right to (a) charge the Client interest on any late payments at a rate of the lesser of (i) ten (10%) percent, compounded monthly, and (ii) the maximum allowable interest rate under applicable law, and may suspend its performance under this Agreement until late payments and accrued interest have been received and (b) withhold delivery of Work Product hereunder unless and until payment is made in full. Payments overdue by more than fourteen (14) days will constitute a material breach of this Agreement by Client.
Client hereby engages the Consultant to perform such services as the Client may request from time to time in accordance with this Agreement (the "Services"). One or more attached Project Specification(s) shall set forth the scope of the Services, including, to the extent applicable, the work Consultant will perform, hourly or fixed fees payable to Consultant for the Services, expenses to be reimbursed, any Client facility, work area(s) and/or tools which may be made accessible to Consultant, and/or other terms and conditions the Parties may agree to. In the event of conflict between the Project Specification and this Agreement, the terms of this Agreement shall control unless the Project Specification explicitly states that a particular term controls over the terms of this Agreement.
All deliverables, ideas, inventions, improvements, methods, processes, works of authorship and other forms of intellectual property that the Consultant conceives, reduces to practice or develops in the course of performing the Services and exclusively for the purposes of providing the Services, including copy, photos, designs, data, software code, ideas, inventions, know-how, materials, marketing plans and schemes, marks, methods, procedures, tools, interfaces, and other forms of technology (collectively, the "Work Product"), will be the sole and exclusive property of the Client.
"Confidential Information" shall mean any information of Client or its clients or of Consultant that the receiving Party knew or reasonably should have known based on the circumstances of disclosure was confidential or proprietary, or that derives independent value from not being generally known to the public, including information designated orally or provided with the legend "Confidential" or "Proprietary." Without limiting the generality of the foregoing, Confidential Information (as further defined below) shall include such Client's and its clients' or Consultant's confidential and proprietary methodologies, strategic plans, social media plans and strategies, financial and business operations, financial information, including sales, costs, profits and pricing methods, employee and consultant information (including the terms of this Agreement), internal organization, personnel matters, business plans, security procedures and approaches, customers, customer lists, user information or data, ideas, processes, methods, designs, artwork, graphics, copy, content, media, concepts, inventions, discoveries, developments, improvements, know-how, research and development efforts, algorithms, decision technology and/or models, specifications, drawings, samples, formulae, applications, software code (object and source), hardware/software design and maintenance tools, technology, sales, marketing, marketing plans or proposals, customer support strategies, or means of doing business or other knowhow or trade secrets, and all copies, derivatives, summaries, extracts, improvements and enhancements to any of the above which are created or developed by either Party, as well as information of third parties as to which either Party has an obligation of confidentiality. "Confidential Information" shall not include any information that: (i) is published or becomes part of the public domain through no act or failure to act on the part of the Client or Consultant or as intended by the Parties as a component of the Services; (ii) the recipient can demonstrate came into its possession from a third party who had a bona fide right to make such information available, free of any confidentiality duties or obligations; (iii) the recipient lawfully knew prior to first disclosure by one of the Parties hereto; (iv) is independently developed by the recipient without use of Confidential Information of the disclosing Party, or (v) the Parties mutually agreed would not be subject to the confidentiality obligations set forth in this Agreement. Unless otherwise expressly provided in this Agreement, the recipient (a) shall use the disclosing Party's Confidential Information solely for the purpose of the performing and receiving the Services contemplated herein, (b) shall not disclose the disclosing Party's Confidential Information to any third-party (other than its affiliates and professional advisors for internal purposes only or, in the case of Consultant, to Consultant's subcontractors), (c) shall use commercially reasonable care (but in no case less care than such Party uses to protect its own confidential information) to prevent the disclosure of the disclosing Party's Confidential Information, and (d) shall only disclose the disclosing Party's Confidential Information to its own employees, contractors, subcontractors and agents solely as necessary to perform its obligations under this Agreement. Unless otherwise expressly provided in this Agreement, each Party recognizes and agrees that (i) nothing contained in this Agreement shall be construed as granting it any property rights, by license or otherwise, to any of the other party's Confidential Information, or to any invention or any patent, copyright, trademark or other intellectual property right that has issued or that may issue, based on the other Party's Confidential Information. Upon termination of this Agreement for any reason, unless otherwise expressly provided herein, each Party agrees to cease using and, within thirty (30) days of written request, to return to the other Party all whole and partial copies and derivatives of the other Party's Confidential Information, whether in its possession or under its direct or indirect control.
Client acknowledges that Consultant is engaged in the process of continuously improving its business processes and Background Technology for a wide variety of clients and that Consultant will continue these activities for the benefit of all of its clients, including without limitation Client. Nothing in this Agreement shall be deemed to preclude or limit Consultant from using these improvements, or its intellectual property developed in the provision of the Services hereunder, and/or developing any products, end-user services, or other deliverable materials for itself or other clients, including web design templates, mobile app frameworks, source code, and source code libraries, so long as the same do not incorporate Client's Work Product. In addition, Client acknowledges that Consultant is engaged in teaching and training its personnel and that Consultant may internally utilize Services and Work Product provided under the Project Specification to train and teach its personnel. Consultant shall be the sole owner of all rights, title and interests in and to, including all patent, copyright, trade secret and trademark rights in and to the Background Technology, which shall be deemed to be excluded from the definition of Work Product. Consultant hereby, as of the time when full payment for the Services has been made (i) irrevocably assigns to Client all right, title and interest worldwide in and to the Work Product and all intellectual property rights, including all patent, copyright, trade secret and trademark rights therein (except, for the avoidance of doubt, any intellectual property rights in and to Background Technology), and (ii) grants to Client a non-exclusive license under the intellectual property rights in and to the Background Technology solely to the extent necessary to enjoy its rights in the Work Product. The foregoing assignment and license grant is expressly conditioned on timely payment by Client of all applicable fees specified in the Project Specification. Client shall retain any and all rights in and to any materials provided to Consultant by Client in the course of performance of this Agreement and exclusively for the purposes of providing the Services.
Any Work Product developed under this agreement shall be transferred to the Client immediately following the Client's payment in full. Client acknowledges and agrees that its ownership in the Work Product shall not be effective until payment is made in full.
In completing any projects subject to this Agreement, Consultant agrees to provide its own equipment, tools and other materials at its own expense, provided, however, that to the extent Client is (1) explicitly deemed responsible for the provision of any equipment, tools and materials in the Project Specification, and/or (2) approves an expense presented by Consultant as a part of the Services, Client hereby agrees to provide such equipment, tools or materials at Client's own expense.
If the Client determines in its sole discretion that the Work Product, excluding Applications, does not conform to the Specifications, the Client shall inform the Consultant of such nonconformity in writing and the Consultant will use commercially reasonable efforts to repair or replace the Work Product so that it conforms to the Specifications within thirty (30) days of such notice (the "Cure Period"). If the Consultant does not effect such conformity by the expiration of the Cure Period, the Client may elect to terminate this Agreement upon written notice to Consultant without further liability to Consultant, in which case Consultant shall refund all prepaid fees for the Work Product that did not meet the Specifications. With respect to Applications, except as expressly provided otherwise in the Project Specification, Consultant shall correct substantial nonconformities with the agreed written Specifications for such Application that are identified by the Client in writing during the Warranty Period without additional charge to Client. Consultant shall not be responsible for correcting errors in the functionality of Applications after the Warranty Period and shall have no obligation to update Applications as may be required by third party hosts or platforms for continuing functionality absent a separate written agreement between the Parties
IN NO EVENT WILL CONSULTANT BE LIABLE FOR ANY CONSEQUENTIAL, INDIRECT, EXEMPLARY, SPECIAL, OR INCIDENTAL DAMAGES OR LOST PROFITS, WHETHER DIRECT OR CONSEQUENTIAL, OF ANY KIND, ARISING FROM OR RELATING TO THIS AGREEMENT, INCLUDING THOSE ARISING AS DIRECT OR INDIRECT RESULT OF THE ACTIONS OF CONSULTANT OR ONE ITS AGENTS, SUBCONSULTANTS, PARTNERS OR CONSULTANTS, WHETHER ARISING IN CONTRACT, TORT OR OTHERWISE, AND REGARDLESS WHETHER CONSULTANT HAS BEEN NOTIFIED OF THE POSSIBILITY OF SUCH DAMAGES. CONSULTANT'S TOTAL, MAXIMUM CUMULATIVE AND AGGREGATE LIABILITY FOR ANY CLAIM IN CONNECTION WITH THIS AGREEMENT, WHETHER IN CONTRACT OR TORT OR OTHERWISE, SHALL NOT EXCEED THE AGGREGATE AMOUNT OF UNDISPUTED FEES PAID BY CLIENT TO CONSULTANT FOR SERVICES PERFORMED UNDER THIS AGREEMENT DURING THE TWELVE (12) MONTHS PRECEDING THE CLAIM. THE PARTIES ACKNOWLEDGE AND AGREE THAT THE FOREGOING LIMITATIONS OF LIABILITY ARE AN ESSENTIAL ELEMENTOF THE AGREEMENT BETWEEN THE PARTIES AND THAT IN THEIR ABSENCE THE ECONOMIC TERMS OF THIS AGREEMENT WOULD BE SUBSTANTIALLY DIFFERENT. CONSULTANT DOES NOT EXCLUDE LIABILITY TO THE EXTENT THAT SUCH LIABILITY MAY NOT BE EXCLUDED OR LIMITED BY LAW.
Client hereby agrees to indemnify and defend Consultant (including any parent, subsidiary or affiliates), and its and their respective officers, directors, owners, members, partners, principals, licensees, employees, subcontractors and representatives harmless from and against all actions, claims, judgments, losses, damages, fines, penalties, costs, expenses or any other liabilities (including reasonable attorney's fees and litigation expenses and expert witnesses' costs and fees) arising out of or related in any way to (i) any information or materials provided by Client to Consultant in connection with any services performed, including Client Materials; (ii) any claims alleging infringement of any intellectual property right or privacy right of any third party arising out of the Client Materials, Client Specifications or Work Product made pursuant to Client Specifications, or (iii) Client's violation of law or breach of its payment obligation under this Agreement. Consultant agrees to indemnify and defend Client from and against any third party claim that the Background Technology, as delivered to Client and when used in a manner authorized by Consultant, infringes a third party's U.S. trade secret, copyright, trademark, or patent rights. In the event of any third-party claim, demand, suit, or action (a "Claim") for which a Party (or any of its affiliates, employees, or agents) is or may be entitled to indemnification hereunder, such Party may, at its option, require the other Party to defend such Claim at its sole expense. An indemnified Party shall provide the indemnifying Party with prompt notice of any indemnifiable Claim (failure or delay to provide such notice shall reduce the indemnifying Party's indemnification obligations to the extent the indemnifying Party is actually prejudiced by such delay or failure) and shall provide the indemnifying Party control of the defense of such Claim (the indemnified Party may participate in, but not control, such defense with its own counsel at its own expense). An indemnifying Party shall not, without the indemnified Party's prior written consent, enter into any settlement or compromise of any Claim that results in any admission of liability or wrongdoing or financial obligation on the part of the indemnified Party. Consultant's indemnification obligations do not apply to the extent that an indemnified claim arises out of: (a) Client's breach of this Agreement; (b) revisions to the Background Technology made by anyone other than Consultant or Consultant's subcontractors; (c) Client's failure to incorporate software updates or upgrades that would have avoided the alleged infringement; (d) Consultant's modification of the Background Technology in compliance with Client Specifications; or (e) use of the Background Technology in combination with hardware or software not provided by Consultant or with Work Product made pursuant to Client Specifications. If an infringement Claim is asserted with respect to the Background Technology, if Consultant believes such a claim is likely, or if Consultant is enjoined from using, distributing or providing any portion of the Background Technology, Consultant will have the right to do any of the following, at its own expense and at its option: (a) procure for Client the right to continue use of the subject Background Technology; or (b) replace or modify the allegedly infringing Background Technology with noninfringing Background Technology of equivalent function and performance. If neither (a) nor (b) is available on commercially reasonable terms, Consultant shall notify Client of that fact, and either Client or Consultant may terminate the Agreement. In the event either Party terminates this Agreement pursuant to this Section, Consultant shall promptly provide Client with a refund of any prepaid fees for the Work Product that cannot be used without the infringing Background Technology.
This Agreement is governed by the laws of companyState without reference to any conflict of laws principles that would require the application of the laws of any other jurisdiction. Client agrees that all disputes arising hereunder shall be adjudicated in the state and federal courts in companyCity, companyState. If any provision of this Agreement is, for any reason, held to be invalid or unenforceable, the other provisions of this Agreement will be unimpaired and the invalid or unenforceable provision will be deemed modified so that it is valid and enforceable to the maximum extent permitted by law.

This table lists the same 33 term explanations in plain, always-present markup, grouped by the contract section they appear in.
| Section | Term | Explanation Title | Explanation Body |
|---|---|---|---|
| Payment | material breach | Not just any late payment — a big one | "Material breach" is a legal term of art for a violation serious enough to justify ending the whole contract, as opposed to a minor slip-up that just gives you a right to claim damages. By defining upfront that any payment more than 14 days late automatically counts as "material," the contract removes the argument a client might otherwise make — that a couple weeks late isn't a big deal — and gives you a clean, undisputed right to walk away. |
| Payment | compounded monthly | Interest that grows on interest | "Compounded monthly" means unpaid interest gets added to the balance each month, and then next month's interest is calculated on that larger number — not just on the original late amount. It sounds like a small technical detail, but over several months it meaningfully increases what a slow-paying client owes you compared to simple (non-compounding) interest. It's also a reaso for them to pay faster. |
| Payment | Work Product | The defined term for everything you build | This is a capitalized, defined term (spelled out fully elsewhere in the contract) that means everything you create for the client — code, designs, documentation. Once a word is capitalized like this in a contract, it's not being used in its everyday sense; it's shorthand for a precise legal definition, and you should always check that definition rather than assume what it covers. |
| Writing a Spec | Services | Another defined term — what you’ve actually agreed to do | "Services" (capitalized) is a defined term referring specifically to the work described in your Project Specifications — not just anything a reasonable person would call "services." This matters because obligations elsewhere in the contract (payment, warranties, IP) are often written to apply only to "the Services," so the boundaries of that definition quietly control how far those obligations reach. |
| Writing a Spec | Project Specification | The real project scope lives in a separate document | We treat this as an actual per-project document — separate from the master agreement — where the specific deliverables, fees, timeline, and any tools or access get spelled out. Anytime a contract splits obligations between a master agreement and a Project Specification, you need to check both documents together, since either one alone tells an incomplete story. But splitting hte project out is good to confirm that you are a contractor, and makes it wasy to add new projects without much help from lawyers, sinc every project can reference the same main agreement. |
| Writing a Spec | shall control | Which document wins if they disagree | "Shall control" is legal shorthand for "this document wins in a conflict." Here it establishes that the master agreement's terms override anything in a Project Specification, unless the spec explicitly says a particular term is meant to take precedence instead. It's the tie-breaker rule for when two parts of your paperwork say different things. |
| IP | Work Product | Everything you make, given one legal label | This deliberately broad, defined term sweeps in code, designs, ideas, and virtually anything else you create while doing the job. Its scope is set by a companion phrase elsewhere in the same sentence — "exclusively for the purposes of providing the Services" — which is the real boundary keeping your general skills and reusable tools from getting swept in too. |
| IP | reduces to practice | Turning an idea into something real | "Conceives, reduces to practice" is patent-law language: "conceiving" is having the idea, "reducing to practice" is actually building or implementing it. Using both words together closes a loophole — it means the client owns not just the finished code, but the underlying ideas and concepts you came up with along the way, from first sketch to shipped feature. |
| IP | sole and exclusive | Full ownership, not just a license | "Sole and exclusive property" means true, complete ownership — not a license to use the work, but actual legal title to it. The distinction matters: a license would let the client use what you built while you kept the underlying rights; this instead transfers the rights themselves, which is why you can't reuse this specific work for another client afterward without a separate carve-out. |
| Confidentiality | Confidential Information | What legally counts as a secret here | This is a defined term, and its definition is broader than most people expect — it covers anything a reasonable person would have understood was sensitive given the context, even without a "Confidential" label stamped on it. Because it's capitalized throughout the contract, every later reference to "Confidential Information" is invoking this specific, broad definition, not a casual understanding of the word. |
| Confidentiality | public domain | Information that's already public isn't protected | This is one of five built-in exceptions to the confidentiality obligations: information that has become publicly available isn't protected as confidential, so long as it became public through no fault of the party who was supposed to keep it secret. It's a common-sense boundary — you can't be sued for "leaking" something that was already common knowledge. |
| Confidentiality | commercially reasonable | A flexible, not perfect, standard of care | "Commercially reasonable care" is a legal standard that asks whether you acted the way a sensible business in your position would — not whether you achieved a perfect, airtight result. It's intentionally flexible rather than a rigid checklist, which protects you from being blamed for a leak that happened despite genuinely reasonable precautions, while still requiring you to take real security seriously. |
| Background Technology | Background Technology | Your reusable tools, kept separate from the client's | This defined term carves out your pre-existing frameworks, libraries, and general-purpose tools from what the client ends up owning. Anything that qualifies as your Background Technology is explicitly excluded from "Work Product," meaning it never transfers to the client — which is why it's worth being specific about what falls into this bucket before a project starts. |
| Background Technology | irrevocably assigns | A permanent, unretractable transfer of ownership | "Irrevocably assigns" means the transfer of ownership can't be undone or taken back later — once it happens (here, upon full payment), it's permanent. This is stronger language than a license grant, and it's why the contract is careful to tie the timing of this irrevocable transfer specifically to the moment payment clears in full. |
| Background Technology | non-exclusive license | Permission to use it, not to own it | A "non-exclusive license" gives the client permission to use your Background Technology (only as much as needed to use their own Work Product) without making them an owner of it, and without stopping you from licensing that same technology to other clients too. "Non-exclusive" is the key word — it's what keeps your reusable tools reusable across your whole business. |
| Code escrow | Work Product | The deliverables being held until payment | Here, "Work Product" refers to whatever this section says gets transferred to the client — and the whole point of this section is that the transfer, and the client's ownership of it, doesn't happen until payment is received in full. Wherever you see "Work Product" used in a contract, it's worth double-checking that it's tied to the definition set earlier in the document. |
| Code escrow | payment in full | No partial credit for partial payment | "Payment in full" is a strict, all-or-nothing threshold — a client who has paid 90% of an invoice hasn't met this bar, and legally, ownership and delivery still haven't triggered. This kind of precise, unambiguous language is intentional: it removes any argument about what counts as "enough" payment to unlock delivery. |
| Code escrow | not be effective | Ownership doesn’t exist yet, even with files in hand | This phrase means the client's ownership rights simply don't exist yet — as a legal matter — until the triggering condition (full payment) is met, regardless of whether they physically have copies of the files. It's a reminder that having a copy of something and legally owning it are two different questions. |
| Expenses | own expense | Who pays, by default | This phrase sets the baseline financial responsibility — absent some other arrangement, each party covers its own costs. Seeing "at its own expense" attached to a party in a contract is a quick way to spot who bears a particular cost by default, before any exceptions kick in. |
| Expenses | Project Specification | Where a cost-shifting exception has to be written down | For the client to become responsible for equipment or tool costs instead of you, this section requires that responsibility to be explicitly written into the Project Specification (or separately pre-approved). If it isn't documented there, the default rule — that you cover your own costs — controls, which is why it's worth getting unusual expenses written down before you incur them. |
| Expenses | provided, however | Here comes the exception | "Provided, however" is a classic legal transition phrase that signals an exception is about to modify the rule just stated. Whenever you see it in a contract, it's a flag to read closely — the sentence you're about to read carves out a situation where the general rule doesn't apply. |
| Warranties | Cure Period | Your window to fix a defect before real consequences hit | The "Cure Period" is a defined 30-day window you're given to fix a reported problem before the client gains the right to terminate and demand a refund. Having a named, bounded fix window like this protects you from being treated as instantly in breach the moment a client is unhappy — you get a fair shot to correct the issue first. |
| Warranties | sole discretion | The client alone decides, no objective standard required | "In its sole discretion" means the client doesn't need to prove an objective standard was violated — their own judgment about whether the work conforms is enough to trigger this clause. It's worth noticing this phrase whenever it appears, because it shifts decision-making power heavily toward whichever party holds the discretion, here the client. |
| Warranties | Warranty Period | The clock on your free bug-fixing obligation | The "Warranty Period" is a defined timeframe (set in the Project Specification) during which you're obligated to fix substantial problems for free; once it ends, ongoing fixes and maintenance become billable, separate work. This term is doing a lot of work in the contract — the length you agree to for the Warranty Period directly sets how long your free support obligation lasts. |
| Limiting Liability | INCIDENTAL DAMAGES | You're not on the hook for the client's lost profits or downstream damages | This is a waiver of "consequential damages" — the indirect, downstream losses that can spiral far beyond the value of the contract itself (a bug causes the client's site to go down, which causes them to lose sales, which causes them to lose a big customer, and so on). Without this clause, you could theoretically be liable for those cascading losses even if they're wildly out of proportion to what you were paid. The all-caps formatting isn't decoration — many states legally require damage waivers like this to be conspicuous (capitalized or bolded) to be enforceable. |
| Limiting Liability | MAXIMUM CUMULATIVE AND AGGREGATE LIABILITY | There's a hard dollar cap on how much you can ever owe | This is arguably the single most important clause for protecting your business financially: no matter what goes wrong, the absolute most you can be forced to pay out is capped at the fees the client actually paid you (and that weren't disputed) over the trailing 12 months before the claim. This turns an unpredictable, potentially business-ending liability into a known, bounded number tied directly to what you were paid. |
| Limiting Liability | ESSENTIAL ELEMENT | Both sides agree the liability cap is core to the deal, not a throwaway line | Calling the liability limitation an "essential element" of the agreement is a legal move meant to make the cap harder to challenge later — some courts are skeptical of liability caps that seem like an afterthought, so this language has both parties acknowledge upfront that the whole deal's pricing was built around this protection existing. |
| Indemnities | indemnify and defend | Cover the costs and run the legal defense | This phrase means more than reimbursing money after the fact — it obligates the indemnifying party to actually step in and pay for (or take over running) the legal defense itself, including attorney's fees, if a covered claim arises. It's one of the most consequential phrases in any contract, since it can mean the difference between owing money and owing an entire lawsuit's costs. |
| Indemnities | prior written consent | No settling behind your back | This requires the party controlling a legal defense to get explicit, written sign-off before settling in a way that admits fault or creates a financial obligation for the other side. Without this phrase, whoever controls the defense could otherwise cut a deal that pins blame or costs on the other party without their say-so. |
| Indemnities | sole expense | Who's footing the bill, unambiguously | "At its sole expense" removes any ambiguity about who pays for a particular action — here, the party choosing to compel the other side to defend a claim, or the party opting to participate with its own counsel, bears that specific cost alone rather than splitting or shifting it. |
| Enforcement | conflict of laws | Blocking a legal workaround to the chosen state | "Conflict of laws" is a body of legal rules courts use to decide which state's law applies when a dispute touches more than one state. Excluding these principles here is a technical but important move — it prevents a court from using those rules to apply some other state's law instead of the one the contract explicitly chose. |
| Enforcement | unenforceable | What happens if a court strikes down a clause | A provision being "unenforceable" means a court has decided it can't legally be enforced as written — often because it conflicts with a state law. This section's severability language makes sure that if any single clause is ever ruled unenforceable, only that clause is affected; the rest of the contract keeps functioning normally. |
| Enforcement | deemed modified | The court rewrites the bad clause instead of deleting it | "Deemed modified" instructs a court, if it finds a clause unenforceable, to rewrite that clause into the closest enforceable version of what the parties intended — rather than just striking it out entirely. This preserves as much of the original bargain as possible instead of leaving a gap where the clause used to be. |
