14-Day Payment Model Launch Checklist

This checklist is needed when the team wants to launch a design loop without losing momentum and without chaotic rework in the middle of the project.

Day 1-3: Fix the target pattern

At the start, what is more important is not integration, but a transparent operating model. It is necessary to document how the operation proceeds from the moment the client pays to the final payment and reporting.

• Describe the role of each party in the settlement chain.
• Agree on the format of operation statuses and the rules for changing them.
• Determine the minimum set of data required for each transaction.

Day 4-7: Prepare processes and milestones

At this stage, the team builds operational discipline: who confirms operations, how exceptions are processed, who makes decisions on controversial cases.

• Collect unified regulations for processing routine and non-routine operations.
• Assign owners in the following areas: operations, finance, compliance.
• Fix SLA for key stages: reception, verification, calculation, report.

Day 8-11: Conduct pilot and stress check

Before going into regular mode, it is important to run test and live cases with a controlled volume in order to see real bottlenecks before scaling.

• Check the correctness of payment statuses and routing.
• Measure the actual timing of operations.
• Check the quality of data for reporting and reconciliation.

Day 12-14: Go to stable mode

The final stage of the launch is completed only after the readiness criteria have been formalized and the team’s operational rhythm has been consolidated.

• Approve the criteria for successful pilot passage.
• Set up weekly monitoring of key metrics.
• Describe an escalation plan in case of deviations.
