How this works
- GST split logic: If seller state = buyer state, charge CGST + SGST (split equally). If different states, charge IGST. We auto-determine this.
- HSN/SAC codes: Type a product name or partial code, the dropdown filters from the GST-Council master list. We've bundled the top 800 codes for common B2B/B2C transactions; the full GST HSN master (~150k entries) is available via cbic-gst.gov.in.
- No server: Everything runs in your browser. PDF generated client-side via jsPDF. We don't see your data.
- Form persistence: Your details auto-save to your browser's localStorage. Refresh the page and your data's still here.
When this isn't enough
Use this for: one-off invoices, low-volume freelance billing, occasional B2B invoices. Switch to dedicated accounting software when you need:
- GSTR-1 filing — monthly upload of all outward supplies. Manually entering 50+ invoices is painful.
- E-invoice / IRN generation — mandatory if your turnover > ₹5 cr (as of FY 2024-25).
- E-way bill generation for goods movement > ₹50k.
- Recurring invoices, payment reminders, accounting integration.

FAQ
Is this invoice GST-compliant?
Yes — it includes all 16 mandatory fields per Rule 46 of CGST Rules: supplier name + address + GSTIN, recipient name + address (+ GSTIN if B2B), invoice number + date, HSN/SAC, description, quantity, rate, taxable value, GST rates (CGST/SGST/IGST split), total. Add your signature/seal manually after download if you want.
What HSN code do I use?
Start typing the product name in the HSN field — the dropdown filters. If your product isn't in the bundled list (we ship the top 800 codes), use the official searcher at cbic-gst.gov.in. HSN digit requirements: 4 digits if your annual turnover ≤ ₹5 cr; 6 digits if > ₹5 cr.
Why CGST + SGST vs IGST?
If you're selling to a customer in the SAME state as your business, GST is split: half CGST (goes to Central Govt), half SGST (goes to State Govt). Different state = full IGST (Central collects, then redistributes). This is automatic in the form once you pick both states.
Can I edit the PDF after download?
The download is a flat PDF — not editable. Re-enter the form values and re-download if you need to change anything. Your form data persists in your browser (localStorage), so it'll be there when you come back.
Is my data sent anywhere?
No. Everything happens in your browser — no server, no analytics on form inputs. Open DevTools and watch the Network tab if you want to verify.
Can I customize the layout / add my logo?
Logo upload is on the roadmap. For now, you can edit the downloaded PDF in Preview/Acrobat to drop a logo image on top. If logo support matters for your invoicing, leave a note via the protodex.io contact form — building this if there's enough demand.
