What is a software development agreement and when to use it

A software development agreement is a contract where the developer undertakes to create custom software for the client for an agreed fee.
This is not a license for ready-made software, but a contract for a custom work.

Typical examples:

• web development, mobile app creation

• internal systems or SaaS tools

• customized e-commerce platforms

• software modules or APIs

Legal framework

Such agreements are governed by:

• the Czech Civil Code (§ 2586+ – contract for work)

• the Copyright Act (Act No. 121/2000 Coll.), as software is a copyrighted work

Mandatory elements of a software development agreement

• Parties (developer and client)

• Project description and scope (features, functions)

• Deliverables (code, access, documentation)

• Deadlines and delivery format

• Price and payment terms

• License terms (use, limits, exclusivity)

• Liability for defects

• Maintenance or support terms

• Termination clause

• Signatures

Common mistakes in practice

• No license included → client legally can’t use what was delivered

• No clear specs or scope = disputes

• Undefined handover and approval process

• No clause for bug fixing or maintenance

• Client assumes full ownership, but developer keeps rights

Recommendations

For the client:

• Ask for full rights to use, edit and adapt the code.

• Define what counts as “completed delivery” and how approval works.

For the developer:

• Define limits on liability and warranty.

• Specify if delivery includes exclusive or non-exclusive rights.

Practice tip

If you deliver custom software without a clear license, you’re legally exposing both parties.
Include license terms, testing procedures, and delivery confirmation in writing to avoid later disputes.

FINAL THOUGHTS – WHAT NOW?

A software development agreement isn’t just a formality – it’s a legal shield, if drafted properly. And a trap, if not.
