Software Development Agreement Checklist For SaaS, Ecommerce And Marketplace Businesses

byAlex Solo12 min read

For SaaS, ecommerce, and marketplace founders, hiring a developer or software agency is a pivotal moment. Yet, many rush into signing a software development agreement without fully understanding the risks or ensuring the contract fits their business model. This can lead to disputes over who owns the code, problems with customer-facing features, regulatory violations, or even losing control of your core technology. Common mistakes include vague project scopes, missing intellectual property (IP) clauses, and failing to require compliance with key federal or state laws. This guide breaks down what to look for in a software development agreement, offers practical examples, and highlights common mistakes so you can protect your business before you sign.

What Is a Software Development Agreement?

A software development agreement is a contract between your business and a developer or development agency. It sets out the terms for building, customizing, or maintaining software. For SaaS, ecommerce, and marketplace businesses, this agreement is often the foundation of your product or platform. It covers what is being built, who owns the code, payment terms, confidentiality, warranties, and what happens if the relationship ends.

In the United States, there is no single federal law that governs software development agreements. Instead, these contracts are shaped by general contract law, federal intellectual property law, and specific state or industry rules. For example, SaaS companies need to consider the Federal Trade Commission (FTC) guidance on negative option billing, while ecommerce businesses may need to comply with state auto-renewal laws and refund requirements. Marketplace platforms may have additional obligations depending on how they handle user data or payments.

Getting your software development agreement right is crucial. It can affect your ability to raise investment, sell your business, or avoid expensive legal disputes. Below, you will find a detailed checklist and practical advice for reviewing your agreement.

Key Clauses to Check in Your Software Development Agreement

  • Scope of Work (SOW): The agreement should clearly define what the developer will deliver. This includes a detailed list of features, platforms (web, mobile, integrations), deadlines, and technical requirements. Attach a separate SOW or project specification if possible. For example, if you are building a SaaS platform with subscription billing, the SOW should specify subscription tiers, payment gateway integration, and user management features. Vague or missing scope is a leading cause of disputes.
  • Intellectual Property (IP) Ownership: Specify who owns the code, documentation, designs, and other deliverables. For most SaaS and ecommerce businesses, you want a "work made for hire" clause or a clear assignment of all IP rights to your company. If the developer is using open source or third-party code, require disclosure and compliance with license terms. For example, if your marketplace uses a third-party payment library, you need to know the license terms and whether you can modify or distribute it.
  • Payment Terms: Set out payment milestones, amounts, and what happens if deliverables are late or incomplete. Avoid paying 100% upfront. Instead, tie payments to acceptance of work. For example, you might pay 20% on signing, 40% after delivery of a working prototype, and 40% after final acceptance testing. This structure gives you leverage if the developer misses deadlines or delivers subpar work.
  • Confidentiality and Data Security: Include strong confidentiality clauses, especially if the developer will access customer data, business plans, or proprietary algorithms. For SaaS and marketplace businesses, require compliance with relevant data protection laws, such as the California Consumer Privacy Act (CCPA) if you have California users. Specify security standards, such as encryption, secure storage, and breach notification requirements.
  • Warranties and Maintenance: Clarify what warranties the developer provides, such as freedom from defects, compliance with specifications, or non-infringement of third-party IP. Address bug fixes, updates, and support after launch. For example, you might require the developer to fix critical bugs for 90 days after launch at no additional cost.
  • Termination and Exit: Spell out how either party can end the agreement, what happens to unfinished work, and how IP is handled if the relationship ends early. This is especially important for long-term or retainer arrangements. For example, if you terminate for cause, you may want the right to access all code and documentation developed to date.
  • Dispute Resolution: Decide whether disputes will be handled in court or through arbitration, and which state's law will apply. For example, if your business is based in Texas but your developer is in California, you need to agree on the governing law and venue. This can affect costs and outcomes if things go wrong.

Each of these clauses should be reviewed in detail and customized to your business model. A generic template rarely covers all the issues that project for SaaS, ecommerce, or platform businesses.

Special Issues for SaaS, Ecommerce, and Marketplace Businesses

While all software development agreements share some basics, SaaS, ecommerce, and marketplace businesses face unique legal risks and regulatory requirements. Here are some areas that deserve special attention, with practical examples:

  • Integration with Customer Terms: Your software development agreement should align with your customer-facing terms of service, privacy policy, and refund policy. For example, if your SaaS offers a free trial with automatic conversion to a paid plan, the developer's work must support clear disclosures and easy cancellation, as required by the FTC and some state laws. If your ecommerce platform promises a 30-day refund, the software must support automated refund processing and customer notifications.
  • Auto-Renewal and Subscription Features: Many states, including California, New York, and Vermont, have specific requirements for auto-renewal disclosures and cancellation options. For example, California's Automatic Renewal Law (ARL) requires clear and conspicuous disclosure of renewal terms, advance notice before renewal, and easy online cancellation. Your developer should build features that allow you to comply, such as renewal reminders and a one-click cancellation button.
  • Data Handling and Security: If your platform collects personal data, the agreement should require the developer to follow applicable data protection laws and industry best practices. For example, the CCPA requires service providers to implement reasonable security procedures and notify you promptly of data breaches affecting California residents. If you serve users in the health or financial sectors, additional federal or state rules may apply (such as HIPAA or GLBA).
  • Refunds and Chargebacks: Ecommerce platforms must ensure that refund and chargeback processes are supported by the software. Some states, like New York and Massachusetts, require specific refund policies for online sales. For example, New York law requires you to process refunds within seven business days for credit card purchases. Make sure the developer understands these requirements and builds appropriate workflows, such as automated refund processing and customer notifications.
  • Accessibility and Compliance: For public-facing platforms, consider including requirements for ADA (Americans with Disabilities Act) accessibility. This may involve building features like screen reader compatibility, keyboard navigation, and color contrast. The Department of Justice has taken enforcement actions against websites and apps that are not accessible to users with disabilities. Also, help support compliance with federal and state advertising and consumer protection rules, such as the FTC's requirements for clear and truthful marketing claims.

Discuss these issues with your developer early, and document them in the agreement or SOW. This reduces the risk of costly rework, regulatory investigations, or customer disputes after launch. For example, if your SaaS platform is expected to support recurring billing, specify in the SOW that the developer must build features for renewal reminders, cancellation, and refund processing to comply with both FTC and state laws.

Checklist: What to Review Before Signing

Use this checklist to review your software development agreement before signing. Each item is critical for SaaS, ecommerce, and marketplace businesses:

  • Is the scope of work detailed and unambiguous? Does it list all required features, integrations, and deadlines?
  • Does the agreement clearly assign all intellectual property rights to your business, including code, documentation, and designs?
  • Are payment milestones linked to deliverables and acceptance testing? Is there a holdback for final acceptance?
  • Are confidentiality and data security obligations spelled out? Does the developer have to comply with the CCPA or other data protection laws?
  • Do warranties cover key risks, such as bugs, IP infringement, and compliance with specifications?
  • Is there a clear process for handling bugs, updates, and ongoing support? Are support response times defined?
  • Are termination and exit procedures fair and practical? Can you access all code and documentation if the agreement ends early?
  • Does the agreement require the developer to comply with relevant laws (FTC negative option guidance, state auto-renewal laws, ADA, etc.)?
  • Are customer-facing features (subscriptions, refunds, disclosures) covered in the SOW and tested before launch?
  • Are dispute resolution and governing law clauses included and appropriate for your business location?
  • Has the developer disclosed any open source or third-party code, and are you comfortable with the license terms?
  • Is there a process for acceptance testing and sign-off before final payment?

Consider having an attorney review the agreement, especially if your business handles sensitive data, operates in multiple states, or relies on recurring revenue models. Even if you use a template, it should be tailored to your business and state requirements.

Common Mistakes and How to Avoid Them

Many founders and operators make the same mistakes when hiring developers. Here are some of the most common issues, practical examples, and how to avoid them:

  • Unclear IP Ownership: If the agreement does not explicitly assign all IP rights to your business, the developer may retain ownership or the right to reuse code. For example, a founder hired a freelance developer to build a SaaS MVP but did not include a written IP assignment. When the founder tried to raise investment, the investor demanded proof of IP ownership, and the developer refused to sign over the rights without additional payment. Always include a written assignment or "work made for hire" clause.
  • Missing Compliance Features: Failing to specify compliance requirements (like auto-renewal disclosures or refund workflows) can lead to regulatory violations. For example, an ecommerce startup in California launched a subscription box but did not include clear renewal disclosures or easy cancellation. The company received a warning letter from the California Attorney General and had to rebuild its subscription workflow at significant cost. List these features in the SOW and require the developer to follow applicable laws.
  • Paying Too Much Upfront: Large upfront payments reduce your leverage if the developer misses deadlines or delivers poor work. For example, a marketplace founder paid a developer 80% upfront, but the developer abandoned the project after delivering incomplete code. The founder had to hire a new team and lost both time and money. Structure payments around milestones and acceptance testing.
  • No Plan for Maintenance: Launching without a maintenance or support plan can leave your business exposed to bugs or outages. For example, a SaaS business launched its platform but had no agreement for ongoing bug fixes. When a critical security bug was discovered, the original developer was unavailable, and the business lost customers. Address ongoing support in the agreement, or plan for a transition to another provider.
  • Ignoring Data Security: If the developer is not contractually required to protect customer data, your business could face liability for breaches. For example, a marketplace platform suffered a data breach after the developer stored passwords in plain text. The business faced regulatory scrutiny and lost user trust. Spell out security standards and require prompt breach notification.
  • Not Aligning with Customer Terms: If your software does not support your advertised features, disclosures, or refund policies, you may face FTC or state enforcement. For example, a SaaS platform advertised a 30-day money-back guarantee but did not have a workflow for processing refunds. Customers complained, and the business had to issue manual refunds and update its software. Make sure the developer understands your customer-facing obligations and builds them into the platform.
  • Overlooking State-Specific Rules: State laws can differ significantly. For example, California's ARL is stricter than many other states, and failure to comply can result in penalties or class actions. Always check whether your agreement and software cover the requirements for the states where you operate or have customers.

Review your agreement with these risks in mind. Do not hesitate to negotiate changes or seek legal review if something is unclear. Using a tailored Software Development Agreement can help you avoid these common pitfalls and protect your business as it grows.

FAQs

Who should own the intellectual property in a software development agreement?

In most cases, the business commissioning the software should own all intellectual property rights in the code, documentation, and related deliverables. This is usually achieved through a "work made for hire" clause and a written assignment of all IP rights. If the developer is allowed to retain ownership or reuse code, it should be clearly spelled out and limited to non-core or generic components. For example, if a developer uses a generic authentication module they built for multiple clients, your agreement should specify what is exclusive to your business and what is not.

What are "negative option" features and why do they project?

Negative option features refer to subscription or billing models where a customer is charged unless they take action to cancel. The FTC requires clear disclosures, easy cancellation, and specific consent for these features. For example, if your SaaS platform offers a free trial that converts to a paid subscription, your agreement should require the developer to build tools that support these legal requirements, such as renewal reminders and a simple cancellation process.

How do state auto-renewal laws affect my software requirements?

Many states, including California, New York, and Vermont, have laws requiring clear disclosure of auto-renewal terms, advance notice before renewal, and easy cancellation. Your agreement should require the developer to build features that support compliance with these rules, such as online cancellation and renewal reminders. For example, California requires a clear and conspicuous explanation of renewal terms and a simple mechanism for cancellation. Failure to comply can lead to penalties and customer disputes.

What happens if the developer uses open source or third-party code?

If your developer uses open source or third-party code, your agreement should require disclosure of all such components and compliance with their license terms. Some open source licenses, like the GNU General Public License (GPL), require you to make your own code public if you distribute it. Make sure you understand the risks and obligations before accepting deliverables with third-party code. For example, if your SaaS relies on a GPL-licensed library, you may need to release your own source code, which could undermine your business model.

Can I use a template software development agreement?

Templates can be a starting point, but they rarely address the specific needs of SaaS, ecommerce, or marketplace businesses. Key issues like IP ownership, compliance features, and data security are often missing or too generic. For example, a template may not address California's ARL or CCPA requirements. It is best to customize the agreement for your business and have it reviewed by a legal professional familiar with your industry and state laws.

Key Takeaways

  • A software development agreement is a critical contract for SaaS, ecommerce, and marketplace businesses. It controls who owns the code, how work is delivered, and what happens if things go wrong.
