Questions & Answers

As answered by people managing JSFiddle and FeeFlow.

What's the story behind your product?

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'.

Which are the primary technologies used for building your product?

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.

Who are some of the biggest customers of your product?

FeeFlow's answer:

  • Digital marketing & creative agencies
  • Independent SaaS founders & Micro-ISVs
  • Cross-border freelancers & remote contractors
  • E-commerce sellers on Shopify & WooCommerce
  • Web development & UI/UX design studios

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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Most fee calculators online are outdated, restricted to US-only rates, and cluttered with invasive ads.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.

How would you describe the primary audience of your product?

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.
