Frequently Asked Questions

How does Happ help developers?

Happ helps developers manage contracts, payments, and collaborations in one place - with tools to define deliverables by feature or sprint, retain proprietary code libraries, document scope changes, and structure milestone payments from wireframe to launch.

Do I have to hand over all my code?

Your agreement defines what's delivered (the project codebase) and what's retained (your proprietary libraries, frameworks, and tools).

How do I handle scope changes during development?

A change-order clause documents new requirements and their cost. The Collaborator approves before work begins.

How should I structure milestone payments for a dev project?

Align milestones with your workflow: wireframe approval, alpha build, beta testing, and final launch.

How do I prevent my retainer scope from expanding every month?

Define monthly deliverables precisely - content volume, formats, platforms, response time. Additions beyond this scope are documented as new scope with additional pricing.

What happens when my retainer period ends?

Your agreement includes renewal terms with a defined window. If the Collaborator doesn't renew, the agreement lapses. No silent continuation, no scope creep disguised as loyalty.

Can Happ automate my monthly retainer payments?

Yes. Retainer payments are tied to your agreement. Your Collaborator pays, you're notified, the record is updated. No manual invoicing every month.
