What is a Software Development Agreement?

A Software Development Agreement is a legally binding contract between a client and a software development agency establishing project scope, IP transfer conditions, payment milestones, bug fix warranties, and liability caps.

When should Intellectual Property (IP) transfer to the client?

Standard agency contract best practice dictates that IP rights transfer to the client ONLY upon receipt of full and final payment for the project.

What is a Change Control / Scope Creep Clause in a software contract?

A Change Control clause outlines the formal procedure for requesting, pricing, and approving additions to the original project scope, preventing clients from expecting unpaid feature additions.

What warranty period should software agencies offer for bug fixes?

Most dev agencies offer a 30-day to 90-day post-launch warranty limited strictly to fixing non-conformities against written functional specifications, excluding new feature requests or third-party API changes.

Why is a Limitation of Liability clause essential for software agencies?

A Limitation of Liability clause caps the maximum financial damages a client can claim against the agency (usually capped at fees paid in the last 6-12 months), protecting the agency from catastrophic indirect loss claims.

Never grant unconditional IP assignment upon signing. Ensure your contract specifies that title and copyright in custom code pass to the client only after full payment of all invoices.

2. Acceptance Testing & Deemed Acceptance Windows

Include a "deemed acceptance" rule stating that if the client does not provide written feedback within 7 business days of milestone delivery, the milestone is deemed accepted and invoice payable.
