OVERVIEW
InvoiceFeeCalc is a free financial utility built for freelancers, SaaS founders, agencies, creators, and businesses that need to understand payment-processing costs before sending an invoice.
THE PROBLEM
Freelancers and businesses often only discover payment-processing costs after the money arrives, making it hard to price invoices correctly across different gateways and regions.
KEY DESIGN & ENGINEERING DECISIONS
01. Multi-Gateway Fee Engine
Accurate fee logic for Stripe, PayPal, Square, and Lemon Squeezy, including regional variations.
02. Reverse Calculation
Enter the amount you want to receive and see exactly how much to invoice after fees.
03. Real-Time Comparison
Compare net payouts across gateways side by side, before a single invoice is sent.
