Are my client records or rates stored on your server?

Never. PDFs are rendered entirely on your device via html2pdf and Web Workers. Closing the tab removes all session data.

Are generated invoices legally binding?

Yes. As long as invoices specify legal entity names, dates, deliverables, and agreed payment terms, they serve as valid commercial claims.

Can I customize logos and payment instructions?

Yes. Add company logos, wire details, and custom terms of service directly.

Commercial Invoice Balance Equations

Total Due = Subtotal - Discount + Tax + Shipping | Subtotal = Sum(Quantity * Unit Price)

{Total}_{due} = \sum (Q_{i} \times P_{i}) - Discount + Tax

Q_i: Quantity of billable line items or hours
P_i: Unit rate or hourly billing price
Tax: Applied sales tax or VAT percentage
Total Due: Net payable balance due from client

Consulting Invoice Example

Billing 40 consulting hours at $125.00/hr ($5,000.00 subtotal) with a 5% client discount ($250.00) and an 8% sales tax on deliverables ($380.00) results in a total payable invoice balance of $5,130.00.
