Aripone is a Florida engineering firm. We modernize legacy platforms and build payment and payout systems for US product companies, on a fixed fee with a written method, starting with an assessment you keep whoever does the build.
Illustrative example, not a client's data.
The brief is usually: we cannot close the month from the processor exports.
Rails, payouts, reconciliation, and the tests that keep them honest. We start with a Payment Operations Assessment: one or two weeks, fixed fee, a severity-ranked report and a costed roadmap.
$9,500 for one week, single rail; $14,500 for two weeks, multi-rail or payouts. Half on signature, half on delivery.
The brief is usually: we cannot hire for the old stack and we cannot stop shipping.
Out of .NET Framework, Java or the monolith without the big-bang rewrite. We start with a Modernization Assessment: two or three weeks, fixed fee, an inventory, a target architecture and a roadmap your board can fund phase by phase.
$16,500 for one application and its data; $24,500 for an estate.
The slow job, pipeline or hot path, measured and explained in five days. Not a database health check.
