Invoice Generator

Invoicing should not require signing up for yet another SaaS account. For freelancers, consultants, and small businesses that send occasional invoices, this browser-based generator produces professional PDFs with all the fields clients expect — line items, taxes, discounts, payment terms, bank details, your logo — without any account or subscription. Fill out the form, preview, and download.

The invoice structure matches what accountants expect globally. Header with your business name and logo. Client details on the billing recipient side. Invoice number and issue/due dates. Line items with quantity, description, unit price, and line total. Subtotal, optional per-line or global tax, discounts, and grand total. Payment instructions including bank details or a pay link. Notes and terms at the bottom.

Tax handling matters a lot. The tool supports global tax models: US sales tax (single rate), EU VAT (with reverse charge for B2B cross-border), UK VAT, Canadian GST/PST/HST, Australian GST, and custom rates. Multi-currency support lets you invoice in EUR while being paid in USD. Line-level taxes work for mixed-rate invoices. PDF export produces a clean, print-ready document; HTML export works for email. Stored client and line-item templates speed up repeat invoicing — the tool saves them in your browser so you can reuse without a server.

Invoice generation combines form-based data entry with PDF rendering. The tool uses a client-side PDF library (jsPDF, pdf-lib, or similar) to assemble the document with typography, tables, and logos. All processing is in-browser so invoices, customer info, and banking details never touch a server — important for small businesses handling sensitive financial information.

Standard invoice fields:
- Invoice number: sequential, unique per business
- Issue date and due date: supports net-30, net-15, or custom terms
- Your business: name, address, tax ID (VAT number, EIN, ABN, etc.)
- Bill to: client business name and address
- Line items: description, quantity, unit price, optional per-line tax
- Subtotal, tax total, discount, total: calculated automatically
- Payment instructions: bank details, PayPal email, Stripe link, etc.
- Notes and terms: payment terms, late fee policy, thank-you note

Tax calculation:
- Simple: single flat rate applied to subtotal
- Line-level: different rates per line (useful for mixed products)
- Tax-inclusive vs exclusive: invoice shows tax as separate line or included in prices
- Reverse charge (EU B2B cross-border): zero VAT charged with a note

Currency:
- Display: symbol, thousand separator, decimal precision per ISO 4217 currency code
- Single-currency: most common, one currency for the whole invoice
- Multi-currency note: add exchange rate reference if useful

Outputs are PDF (for email attachment and print), HTML (for inline email body), and CSV (for accounting system import). Templates save settings, line items, and client info locally so recurring invoices take seconds rather than minutes. For integration with accounting software, export as CSV or XML matching your software's import format.

Full invoicing platforms (QuickBooks, FreshBooks, Wave) handle everything including tracking, recurring, and payments, but require subscriptions and onboarding. Word/Google Docs templates work but lack tax automation. This tool sits in between: professional PDFs with tax handling and branding, zero subscription, and complete privacy (nothing leaves your browser). Perfect for freelancers and small businesses with occasional invoicing needs who don't want another SaaS bill.
