Questions & Answers

As answered by people managing FeeFlow.

  1. What's the story behind FeeFlow?

    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'.

  2. Which are the primary technologies used for building FeeFlow?

    Astro (Server-Driven Static Architecture), TypeScript, Tailwind CSS, and Cloudflare Pages Edge Network for global sub-millisecond calculation speeds and zero client-side tracking.

  5. Why should a person choose FeeFlow over its competitors?

    Most fee calculators online are outdated, restricted to US-only rates, and cluttered with invasive ads.

  6. How would you describe the primary audience of FeeFlow?
