Invoice Maker

Invoice Maker turns any open email — an order confirmation, a client request, a job you just finished — into a professional, branded invoice without retyping everything by hand. HOW IT WORKS 1. Open an email in Gmail, Outlook Web, or any other webmail. 2. Click the Invoice Maker icon. It scans the visible email and pre-fills an invoice form with its best guesses: sender/company name, date, amounts, and reference numbers. 3. Review and correct the form — nothing is ever generated without you seeing and confirming the data first. 4. Generate a polished PDF invoice using your own saved branding (logo, accent color, font, business details), or export the same invoice as CSV/JSON for your bookkeeping software. YOUR DATA NEVER LEAVES YOUR BROWSER Extraction is done with local pattern matching, not AI — no email content is ever sent to any server, including ours. There is no backend, no account, and no tracking. Everything — templates, branding, invoice history — is stored locally in your browser. FEATURES • Works with Gmail, Outlook Web, and a generic fallback for any other webmail (via text selection) • Editable autofill — every guessed field can be corrected before anything is generated • Multiple branding templates (logo, color, font, business details) — pick one per invoice • NL/EU defaults out of the box (BTW/VAT %, KvK number, IBAN, EUR) — fully editable/renameable for other locales • Optional payment link (Stripe, PayPal.me, Tikkie, Mollie, etc.) rendered as a clickable "Pay online" button on the PDF • CSV/JSON export alongside the PDF for easy import into accounting tools • 100% client-side — no backend, no account, no tracking, no email content ever transmitted Built for freelancers and small businesses who want invoices out the door fast, without handing email content to a third party to do it.
