Frequently Asked Questions
Is it safe to upload my company's financial CSV to FeeFlow?
100% yes. FeeFlow operates as a zero-knowledge, client-side auditor. Your file is parsed directly inside your browser RAM using an isolated Web Worker. Not a single row, amount, or customer record is transmitted across the internet or stored on our servers. You can open your browser's Developer Tools (Network tab) to verify zero network requests during the entire audit.
Which Stripe export should I download for this audit?
For the most forensic breakdown, go to Stripe Dashboard → Reports → Balance → click 'Export' and select 'Itemized balance change from activity' (All columns). You can also use the standard 'Payments' or 'Charges' CSV export. The parser automatically detects headers and normalizes currency denominations.
What is an 'Effective Take Rate' and why is it higher than 2.9% + 30¢?
While Stripe advertises 2.9% + $0.30 for domestic cards, auxiliary services and non-standard transactions inflate your real cost. Adding international cards (+1.5%), currency conversion (+1.0%), Stripe Billing (0.7%), Stripe Tax (0.5%), Radar fraud screening ($0.02), and non-refundable fees on refunds pushes the median merchant's True Effective Rate to 3.8% - 5.7%.
How can this audit help me renegotiate my Stripe rates?
Merchants processing over $50,000/month or $500,000/year possess substantial leverage to secure Interchange-Plus (IC+) custom pricing or volume discounts. This audit provides an itemized, mathematically verifiable breakdown of your fee leakage and generates a professional rate-cut demand letter formatted for procurement review.
How does the tool handle multi-currency statements?
The auditor reads currency identifiers per row (USD, EUR, GBP, AUD, CAD, JPY). For standard fiat currencies, integer cent values (e.g. 10000) are normalized by dividing by 100, while zero-decimal currencies like Japanese Yen (JPY) are evaluated without division.
