PSP invoices routinely overcharge fintechs by 0.2 to 0.5 percent of volume. Six structural reasons your payment provider invoice is wrong, and how to catch it.

Cutting reconciliation cost means addressing two costs: the hours a team spends matching, and the fee leakage manual review never catches. Here is how.

The industry is obsessed with getting licensed and almost silent on what licensure obligates you to do. Third-party oversight is a named exam criterion, and fee accuracy is part of it.

Volume alone predicts nothing. Four walls arrive in order, and the one that matters is the day your median exception age passes your shortest dispute window.

Five stages: the contract as versioned data, events at transaction grain, deterministic repricing, a categorised exception queue, and recovery that writes the cause back upstream.

Interchange is set by schedules you have no part in writing. What you can reduce is the interchange you were billed in error, the interchange you failed to qualify out of, and the margin on top of both.

The regulator defines four pricing options, and separates two of them by a single line item. Here is how to read your own contract and tell which one you are on.
Send one provider contract and a month of statements, in whatever format they exist. We reconstruct the pricing, verify the transactions, and show you the discrepancies on your own numbers.
Start with one contract. No integration required to see the first findings.
Bluefyn never moves, holds, or custodies funds.
