The engagement runs across three phases. Each closes with a written deliverable and a review before the next begins.
PHASE 1 · DISCOVERY AND DESIGN
Kickoff workshop, feature scoping, wireframes, and interactive prototypes covering the primary user flows.
PHASE 2 · BUILD
Sprint-based development for iOS and Android, integration with backend services and third parties, and weekly demos.
PHASE 3 · QA AND LAUNCH
End-to-end QA, TestFlight and internal-track releases, store submission, launch coordination, and a 60-day post-launch support window.
Not included: backend hosting fees, third-party service subscriptions, ongoing feature work, App Store and Play Store fees, and localization. New scope can be added in writing at any time.

The Mobile App Development Contract template is a five-page document for putting an engagement between the Developer and the Client on paper before work begins. It carries an overview with stat cards, a three-phase scope of work, a fee table with a computed total and payment schedule, and an acceptance page with inputs and signatures.
It is intentionally simple: rename what needs renaming in Bonsai, edit the scope and fees to match your engagement, and send. Merge fields handle the party details and date, and the last page collects the fields you need plus both signatures.
Everything below comes pre-configured. Turn sections on or off, edit the copy, or add your own — Bonsai remembers your choices for next time.
Do you submit to the stores? Yes — App Store and Play Store submission is included; the Client provides developer accounts and any required legal information.
Is ongoing maintenance included? Sixty days of post-launch defect fixes are included; ongoing feature work is scoped as a separate maintenance retainer.
Who owns the code? The Client owns the source code and IP on final payment; the Developer retains rights to any pre-existing tooling.
