Essential Contracts Every Web Developer Needs

From freelance gigs to SaaS deals — the contracts every developer should have on hand.

Why Developers Need Contracts

Software work has unique risks: scope creep ('just one more feature'), unclear IP ownership, hosting/maintenance disputes, and clients reneging on milestone payments. The right contracts make every project predictable and profitable.

Must-Have Contracts for Developers

Critical Clauses for Dev Contracts

Scope of work — list specific deliverables, technology stack, and what's NOT included. Acceptance criteria — define what 'done' means (e.g., 'passes 95% of test cases'). Bug warranty period — typically 30 days post-launch for free fixes. Hosting/credentials — who provides what. IP ownership — code transfers upon final payment, not before.

Avoiding Scope Creep

The #1 dev pain point. Solution: change order process in every contract. State that any feature/change beyond the SOW requires a written change order with new pricing and timeline. Be firm — verbal 'just add X' requests are how 80-hour projects become 200-hour projects.

FAQ

Should I keep the source code or transfer it to the client?

Standard practice: client owns the deliverable code; you retain rights to your underlying tools, libraries, and frameworks. Specify this in your IP clause.

How do I handle hosting and ongoing maintenance?

Either include a separate maintenance clause (with hourly rate for issues outside scope) or sign a separate Maintenance Agreement after launch. Don't bundle ongoing support into a project price.

What if a client wants to use my code in their other projects?

Limit usage in your IP clause: 'Client owns the code for use in [Project Name]; reproduction or use in other projects requires separate licensing.'
