Mobile App Development Contract Template

Mobile app projects fail at the edges: the client assumed Android was included, the app store rejected the build, or no one agreed who fixes bugs after launch. This template pins down platforms and devices, milestone payments, acceptance testing with a deadline, app store submission (and why approval can't be guaranteed), third-party costs like developer accounts and APIs, source code handover, and a warranty period for bug fixes.

And
Alex Chen (Acme Bakery)

$2,400.00

$720.00
Delivery deadline
October 24, 2026

Scope & Platforms

The Sender will build the mobile app described in a full redesign of the Acme Bakery marketing website, including a new homepage, menu page, and online ordering integration for the platforms and minimum OS versions stated there. Features not listed are out of scope and require a written change request with its own estimate.

Payment Terms

The total fee for this engagement is $2,400.00, payable in milestones tied to the deliverables in a full redesign of the Acme Bakery marketing website, including a new homepage, menu page, and online ordering integration.

A deposit of $720.00 is due before work begins. Remaining milestone payments are invoiced as each phase is completed and are due within 7 days of the invoice.

Late payments may accrue a 1.5% monthly late fee, and work on subsequent milestones may be paused until outstanding balances are settled.

Acceptance Testing

At each milestone, the Client has 7 days to test and report defects against the agreed scope. If no defects are reported in that time, the milestone is accepted. Reported defects are fixed before moving on.

App Stores & Third Parties

App store developer accounts are held in the Client's name. The Sender will prepare and submit the app, but approval is decided by Apple and Google and cannot be guaranteed; changes needed to meet store guidelines that go beyond the agreed scope are billed separately. Third-party services (APIs, hosting, push notifications) are paid by the Client.

Warranty & Support

For 30 days after launch, the Sender fixes defects in the delivered code at no cost. Ongoing maintenance, OS updates, and new features after that are available under a separate agreement.

Ownership & Intellectual Property

Upon receipt of full payment, all final deliverables produced under this agreement become the property of the Client, who receives full rights to use, reproduce, and modify them for their intended purpose.

Until full payment is received, all work product remains the property of the Sender. The Sender retains the right to display the work in their portfolio and marketing materials unless the Client requests otherwise in writing.

Any third-party assets used (fonts, stock media, libraries) remain subject to their own original licenses.

Confidentiality

Both parties agree to keep confidential any non-public business, technical, or financial information shared during this engagement, and to use it only for the purpose of completing the work described in a full redesign of the Acme Bakery marketing website, including a new homepage, menu page, and online ordering integration.

This obligation survives the completion or termination of this agreement and continues for 2 years afterward.

Termination

Either party may terminate this agreement with 14 days' written notice. If the Client terminates before completion, the Sender will be paid for all work completed up to the termination date, and the deposit is non-refundable.

If the Sender terminates, any portion of the deposit exceeding the value of work already completed will be refunded to the Client within 14 days.

Limitation of Liability

The Sender's total liability under this agreement is limited to the total fees paid by the Client. Neither party is liable for indirect, incidental, or consequential damages arising from this engagement.

Independent Contractor Relationship

The Sender is engaged as an independent contractor, not an employee, partner, or agent of the Client. The Sender is responsible for their own taxes, insurance, and benefits, and is free to accept other engagements during the term of this agreement, provided they do not conflict with the confidentiality obligations above.

Governing Law & Entire Agreement

This agreement is governed by the laws of the State of Delaware, without regard to conflict-of-law principles.

This document represents the entire agreement between the parties regarding a full redesign of the Acme Bakery marketing website, including a new homepage, menu page, and online ordering integration and supersedes any prior discussions or proposals. Any changes must be made in writing and agreed to by both parties.

By signing below, both parties confirm they have read, understood, and agree to the terms above.

FAQ

What if Apple rejects the app?

The template says approval is decided by the stores, commits you to prepare and submit, and bills changes beyond the agreed scope separately.

How long should an app bug-fix warranty be?

30 days is common for freelancers. It covers defects in your code, not new features or OS changes.

Who owns the source code?

The client, on full payment, under the Ownership clause. Open-source libraries stay under their own licenses.
