As answered by people managing Fullstack Vue and FeeFlow.
FeeFlow's answer:
FeeFlow was born from founder frustration with payment processor ambiguity. Sending a $5,000 invoice only to receive $4,830 due to unexpected cross-border and percentage fees created constant cash-flow leaks. We engineered FeeFlow to give online businesses mathematical transparency and automated gross-up invoice pricing before hitting 'send'.
FeeFlow's answer:
Astro (Server-Driven Static Architecture), TypeScript, Tailwind CSS, and Cloudflare Pages Edge Network for global sub-millisecond calculation speeds and zero client-side tracking.
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Most fee calculators online are outdated, restricted to US-only rates, and cluttered with invasive ads.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.
