Frequently Asked Questions
How does the payment processing fee pass-through work?
Payment processors like Stripe charge 2.9% + $0.30 on the total transaction amount. If you want the client to cover this fee so that your net payout equals your exact subtotal, the invoice total must be mathematically grossed up using the formula: Gross = (Total + $0.30) / (1 - 0.029). Our calculator performs this exact calculation automatically.
How are discounts and taxes ordered in the invoice calculation?
In standard accounting practices, discounts are applied first to determine the net taxable subtotal. Sales tax or VAT is then calculated on this discounted amount, preventing clients from being overtaxed on money they did not pay.
Can I export this invoice as a PDF?
Yes! Click the "Print / PDF" button to open your web browser’s native print dialog, where you can select "Save as PDF" to generate a clean, professional invoice document ready to send to your client.
Is my financial data or client information stored on your servers?
No. All calculations, line items, and financial values execute strictly within your local browser memory. Zero financial data is ever sent across the network or stored in any database.
Can I combine hourly and fixed-price items on the same invoice?
Yes! Every line item has an individual type switcher (Hourly vs Fixed). You can bill 20 hours of 3D modeling alongside a fixed $1,500 milestone fee on the same invoice.
