Milestone 5: Final Delivery and Launch

Target Date: target_completion

Deliverables: Production deployment, source code, documentation, training, final acceptance

Payment Trigger: 20% of Total Cost

3.2 Schedule Dependencies

The timeline is contingent upon: (a) Client providing timely feedback, approvals, and decisions within five (5) business days of each review checkpoint; (b) timely access to Client's systems, data, APIs, and personnel as required; (c) no material changes to the project scope; and (d) timely payment of milestone invoices. Delays attributable to Client shall extend the project timeline day-for-day.

4. Acceptance Testing

4.1 Testing Process

Upon completion of each milestone deliverable, Developer shall submit it to Client for acceptance testing. Client shall have ten (10) business days from the date of submission (the "Testing Period") to test the deliverable against the agreed acceptance criteria and either: (a) accept the deliverable in writing; or (b) provide a written notice identifying specific defects or non-conformities with the Specifications.

4.2 Acceptance Criteria

Acceptance criteria for each milestone shall be defined during the requirements phase and documented in the Specifications. At a minimum, acceptance criteria shall address: (a) functional completeness (all specified features work as described); (b) performance (meets defined performance benchmarks); (c) security (passes defined security tests); and (d) compatibility (works on all specified platforms and browsers).

4.3 Defect Correction

If Client identifies defects during the Testing Period, Developer shall correct such defects within five (5) business days at no additional cost, provided the defects represent a failure to meet the agreed Specifications. Client shall then have five (5) business days to re-test. If defects persist after two (2) correction cycles, the Parties shall meet in good faith to determine an appropriate resolution, which may include additional correction cycles, scope adjustment, or fee reduction.

4.4 Deemed Acceptance

If Client does not respond with acceptance or defect notification within the Testing Period, the deliverable shall be deemed accepted. Deemed acceptance shall have the same effect as written acceptance for all purposes, including payment triggers.

5. Change Request Process

5.1 Change Orders

Any changes to the Specifications, scope, milestones, or deliverables after the requirements phase shall be documented in a written Change Order. The Change Order process is as follows:

(a) Either Party may submit a written change request describing the proposed change and the business rationale;

(b) Developer shall evaluate the change request and provide Client with a written assessment within five (5) business days, including the impact on scope, timeline, and cost;

(c) If the change requires additional work, Developer shall quote the additional cost at the hourly rate of hourly_rate_changes per hour, or at a fixed price mutually agreed upon;

(d) Client shall approve or reject the Change Order in writing within five (5) business days; and

(e) No changes shall be implemented until the Change Order is signed by both Parties.

5.2 Scope Creep Prevention

Developer shall promptly notify Client if any request or direction from Client appears to fall outside the agreed Specifications. Developer shall not be required to perform out-of-scope work without a signed Change Order and shall not be liable for delays resulting from pending Change Order approvals.

6. Payment Terms

6.1 Total Project Cost

The total cost for the development of the Software is total_cost (the "Total Cost"). The Total Cost covers all labor, project management, and standard development tools required to deliver the Software in accordance with the Specifications.
