The whole invoicing job, in one place — no account, ever
Full GST depth with a GSTR-1-ready export. A client and item book that never asks you to sign up. Every document in the chain — quotation, proforma, invoice, receipt, credit note, purchase order — on one engine. And PDFs that carry your name, not ours.
What FacturaFit is: a set of document tools that run entirely in your browser. For India: GST invoices with the CGST/SGST-or-IGST decision made from the place of supply, a live Rule 46 checklist, HSN/SAC tax summaries and a GSTR-1-ready JSON export. For Spain: facturas with the cuadro de IVA by rate and IRPF retention done in the right order — written natively in Spanish, with Verifactu dates stated honestly, including what has only been announced and not yet published.
What it is not: we file nothing. No IRN generation, no GSTN submission, no Verifactu system, nothing sent to the AEAT. Documents and an export file — filing stays on the official systems, and every page here says so.
India — the GST suite
GST Invoice Generator
The flagship: Rule 46 checklist, place-of-supply split, HSN summary, UPI QR and the GSTR-1-ready export.
Quotation Maker
Quotes with a validity date that convert to proforma or invoice in one click.
Proforma Invoice
Labelled "not a tax invoice" on the document itself — the honesty some tools skip.
Payment Receipt
Receipts against an invoice (balance computed) or standalone, labelled as such.
Credit Note (GST)
Adjustments that mirror the original invoice’s tax split — never re-derived.
Purchase Order
The buyer-side mirror: your business buys, the engine and rounding stay the same.
GSTIN Validator
Format, state code and checksum — validated digit by digit, in your browser.
My Documents (client book)
Your clients, items, documents and numbering — stored only in your browser, exportable as one backup file.

España — facturas en español, escritas en español
La suite española no es una traducción: presupuestos, facturas proforma, recibos y notas de crédito con el cuadro de IVA por tipos, la retención de IRPF en el orden correcto, y las fechas de Verifactu en su forma fechada y honesta — 2027 vigente; octubre de 2028 anunciado y todavía sin publicar en el BOE.

The promises, in checkable form
- Open the PDF: zero branding from us — count it yourself.
- Count the clients: the book has no cap, because there is no paid tier above free to upsell you into.
- Check the rule: every figure on a tool page names its official source and the date it was verified.
- Check the boundary: we generate documents; filing happens on the official systems. Always stated, never implied otherwise.
