About Invoice Generator

A quick invoice builder with up to 8 line items, each having a description, quantity, and rate. Subtotal, discount (percentage), and tax (percentage) are computed live. The summary panel shows total due with a breakdown of discount amount and tax amount. Two presets—Design Sprint and Web Build—populate example line items. Export the invoice as a JSON file with per-item line totals and all computed values, or copy a plain-text summary.

  • Up to 8 line items with description, quantity, and rate per item
  • Discount applied before tax: taxed_base = subtotal - discount; total = taxed_base + tax
  • Two presets: Design Sprint (brand exploration + deliverables, 5% discount) and Web Build (dev sprint + support retainer)
  • JSON export includes per-item line totals plus full totals breakdown with timestamp

Frequently Asked Questions

Can I customize the currency?
The tool formats everything as USD. The JSON export doesn’t include a currency field, so you can treat the numbers as any currency—just note that the on-screen formatting will show dollar signs.
Why is there an 8-item limit?
It’s a quick-build tool, not full invoicing software. Eight items covers most freelance invoices. For complex multi-page invoices with payment terms and client details, use dedicated invoicing software.
