Payments product development in fixed phases, in your repository
We build the parts of a payments product that have to be exact: the ledger, the payout flow, partner integrations and reconciliation. Each phase is scoped and priced in writing and ends with working software in your staging environment.

How we work with your team
We follow your branching, review and deployment process. A named lead from our side attends your planning and stand-ups. Your engineers review and approve every merge. At the end of each phase we write down what is done, what is open and what we would change.
