Why this domain exists, how the tool works, and what we mean when we say "browser-first." Honest answers to the questions you'd ask if we were across the table.
FyInvoice exists because billing is studio work. You sit down with the work done — the hours logged, the deliverables shipped, the retainer earned — and you walk out with an invoice that adds up, looks right, and has a payment link. Most online billing tools fight the metaphor: they bundle full bookkeeping that you didn't ask for, they cap the free tier at five clients, they push you to sign up before you can even draft the first line item.
fyinvoice.com is built page-by-page around the actual jobs people walk into a billing studio for. 'GST invoice with HSN codes.' 'VAT invoice for an EU client.' 'Freelance invoice, no tax fields.' 'Multi-currency for cross-border.' 'Branded letterhead for the studio.' 'UPI QR for payment.' Each is a specific search; each gets its own page, framed in the language of the query, with the rest of the studio quietly available when the work grows.
A studio isn't an accounting suite. It's a focused space where the math reconciles, the PDF prints, and the invoice ships — without you fighting the tool.
Most of FyInvoice runs entirely in your browser. Type the seller and buyer GSTINs, add the line items, hit export. Per-line tax (CGST/SGST split for intra-state, IGST for inter-state, multi-rate VAT for UK/EU) resolves before the invoice-level adjustments. Multi-currency formatting follows the locale (Indian lakh grouping for INR, dotted thousands for EUR). PDF generation runs client-side. Drafts save to a local library so next month's invoice starts from this one. No signup, no upload, no monthly fee for the basics.
A handful of features need cloud compute — recurring billing schedules (cron infrastructure that runs whether your tab is open or not), email delivery + read tracking, live FX conversion at today's rate, AI assists like auto-fill from quotes. Indian e-invoicing (IRN generation) needs the GSTN compliance API. E-signature on invoices needs cryptographic key management. Those use a one-time encrypted server session that deletes the file the moment the result is ready. We label which features work which way with a small icon on every page.
The static billing flow — GST + VAT + freelance, multi-currency, branded letterhead, payment QR, manual send — is free forever. No signup, no watermark on PDFs, no client-count cap. The line we draw isn't 'a few features for free, the rest paid.' It's 'a complete static flow free, automation paid.' If you bill a few clients a month and your accountant handles the rest, the free tier is the actual product and you'll never need to upgrade.
Cloud Pro at $9/mo adds the automation layer — the part that turns billing into a system that runs on its own. Recurring schedules. Email delivery + read tracking + reminder cadences. Live FX conversion (today's rate, auto-updated). AI assists. Client portal. Cross-device sync. We priced it honestly for the infrastructure: cron, email deliverability, FX feeds, AI inference all carry real per-use cost. At $9 it still sits 53% under FreshBooks Lite ($19, 5-client cap), 44% under Wave Pro ($16, bundles bookkeeping you didn't ask for), barely under Invoice Ninja Pro ($10).
Business at $19/mo per seat is the compliance + team layer. Indian e-invoicing (IRN via the GSTN API, mandatory above ₹5cr turnover). E-signature on invoices with cryptographic audit trail. Multi-entity billing for businesses with multiple registered companies. SAML SSO + SCIM. GST returns export. 42% under FreshBooks Plus ($33), 37% under QuickBooks Online ($30+). For finance teams, contracts desks, and GST-compliant SMBs.
FyInvoice is one of five focused fronts for the FyTools utility suite. The full toolkit lives at fy.tools, and the broader Fyboard platform — contracts, knowledge, automation, payroll — at fyboard.com.
Same team. Same browser-first architecture. Same pricing model. Different doors — so the search intent and the landing always match up. FyInvoice on fyinvoice.com; the whole toolkit on fy.tools; the broader platform on fyboard.com.
