As answered by people managing FeeFlow and Selfcommit.dev.
FeeFlow's answer
FeeFlow was born from founder frustration with payment processor ambiguity.

We engineered FeeFlow to give online businesses mathematical transparency and automated gross-up invoice pricing before hitting 'send'.

FeeFlow's answer
FeeFlow's answer
FeeFlow uniquely combines multi-country payment intelligence across 46 sovereign nations with an instant reverse Gross-Up invoicing engine. Unlike static calculators, FeeFlow dynamically compares Stripe and PayPal in real time, factors in cross-border/FX surcharges, and generates polite client invoice notes—all within a 100% private, client-side architecture.
FeeFlow's answer
Most fee calculators online are outdated, restricted to US-only rates, and cluttered with invasive ads. FeeFlow delivers 2026-accurate localized rates across 46 currencies, calculates ACH $5 cap savings, reveals true international deductions, and provides zero-latency client-side speed with complete privacy and clean modern UI.
FeeFlow's answer
FeeFlow is built for freelancers, SaaS founders, digital agency owners, e-commerce merchants, and remote consultants who bill domestic and international clients and want to protect their profit margins from hidden payment processor deductions.
