1. Independent Non-Intermediary & Non-Bank Status

FeeFlow (accessible at https://feeflowcalculator.com) is an independent web-based financial estimation and educational research utility. We are not a bank, payment service provider (PSP), payment aggregator, money services business (MSB), licensed payment institution, or financial advisor under any regulatory framework—including but not limited to the Reserve Bank of India (RBI), Saudi Central Bank (SAMA), Banco Central do Brasil, UK Financial Conduct Authority (FCA), European Banking Authority (EBA), Monetary Authority of Singapore (MAS), or U.S. FinCEN.

FeeFlow does not process transactions, handle consumer credit cards, initiate bank transfers, or hold escrow funds. Our services consist purely of mathematical simulations executed within your client web browser.

All outputs provided by FeeFlow—including transaction cost estimates, gross-up invoice pricing, foreign exchange rate spreads, and statutory tax calculations (such as India 18% GST, Mexico 16% IVA, and Saudi Arabia 15% ZATCA VAT)—are provided strictly for general informational and planning purposes.

They do not constitute certified accounting records, tax advice, audit-compliant invoices, or binding merchant quotes. Actual fees may vary depending on merchant category codes (MCC), card interchange qualification, blended vs. interchange-plus contract terms, and statutory reverse-charge regulations.

Always consult a certified public accountant (CPA), chartered accountant, or qualified tax attorney before making commercial commitments.
