invoice-generator-pro

A professional invoice generator produces PDF invoices for freelancers, consultants, agencies, and small businesses — itemised line-by-line with quantity, unit price, and totals; configurable tax (sales tax / VAT / GST); payment terms (Net 30, due on receipt); business + client info; logo upload; digital signature; multi-currency support; and sequential invoice numbering. The ZTools Invoice Generator Pro produces print-ready PDFs in the browser via jsPDF, with no signup, no watermark, no quota, no upload of business data. Settings persist locally for fast re-invoicing of repeat clients.

Use cases​

Freelancer / consultant invoicing​

Project complete, send invoice. Generator handles itemisation, tax math, professional formatting — faster than doing it in Google Docs.

Agency client billing​

Multi-line invoices with hourly rates per role, expense reimbursements, retainers. Generator handles the complexity without spreadsheet errors.

Small business sales​

Per-product line items, sales tax, discounts. Cheaper than QuickBooks / Xero for low-volume sellers.

International invoicing​

Multi-currency display, VAT / GST handling per region, English + native-language invoice text. Saves the back-and-forth with overseas clients.

How it works​

  1. Set business info — Your name / company, address, tax ID, logo upload, payment instructions (bank, PayPal, crypto). Persists for future invoices.
  2. Set client info — Client name, address, contact email. Save as template for repeat clients.
  3. Add line items — Description, quantity, unit price. Subtotal calculated.
  4. Configure tax — Sales tax / VAT / GST as percentage. Multiple tax types supported.
  5. Set payment terms — Net 30 default; "Due on receipt", custom days, or specific date.
  6. Optional digital signature — Type or draw signature; appears on the invoice PDF.
  7. Generate PDF — Print-ready letter / A4 PDF; download or email directly.

Frequently asked questions​

Is it accepted by tax authorities?

Generally yes — the format is standard and includes all required fields. Some jurisdictions have specific requirements (e.g. EU mandatory VAT number on cross-border invoices). Verify with a local accountant for high-volume / regulated industries.

Does it integrate with QuickBooks / Xero?

Not directly. Export PDF; manually log in your accounting software. For automated bookkeeping, use a paid SaaS invoicing tool (FreshBooks, Wave, Bonsai).

Can I save invoice templates?

Yes — settings + line items persist locally. Reload the tool, last invoice is restored.

Is anything uploaded to a server?

No — PDF generation is browser-side via jsPDF. Your business + client info stays on your device.

Multi-currency support?

Yes — pick the currency for each invoice (USD, EUR, GBP, INR, AUD, CAD, JPY, +30 more). Conversion rates not included; use a currency converter for that.

Can I track paid / unpaid?

Not in this tool — for tracking, use a SaaS invoicing tool. This is for one-off PDF generation.

Tips​

  • Always include payment instructions (bank account, PayPal email, accepted payment methods) — clients pay faster when the path is obvious.
  • Use sequential invoice numbers (e.g. 2026-001, 2026-002) — required for tax records.
  • Net 30 is standard; for new clients, consider 50% upfront. For overdue, follow up at +7 days, +14 days, +21 days.
  • Include your tax ID / EIN / VAT number — required in many jurisdictions for B2B invoices.
  • For repeat clients, save their info as a template — skip data entry on every invoice.
