FAQ

Is this invoice generator really free?

Yes. There's no sign-up, no limit on invoices and no watermark. A small "Made with ankdya.in" line is added at the bottom, and you can switch it off.

Where are my details stored?

Only in your browser, on this device. Nothing you type is uploaded to our servers. Your business details are remembered so your next invoice is faster; Clear all removes everything.

Can I make an invoice without GST registration?

Yes. Choose No GST as the tax type and "Invoice" as the document type — a business that isn't GST-registered must not charge GST. Composition-scheme businesses and suppliers of exempt goods use "Bill of Supply".

When do I use CGST + SGST, and when IGST?

When you and your customer are in the same state (intra-state supply), GST is split equally into CGST and SGST — for example, 9% + 9% for 18%. When the place of supply is in a different state (inter-state), charge IGST at the full rate.

Do I need HSN or SAC codes?

HSN codes are for goods and SAC codes for services. On B2B tax invoices, businesses with turnover up to ₹5 crore must show at least 4 digits, and businesses above ₹5 crore at least 6 digits.

Does this tool create e-invoices (IRN)?

No. Businesses with turnover above ₹5 crore must also register B2B invoices on the government's e-invoice portal (IRP) to get an IRN and QR code. This tool creates regular invoices, which is what most small businesses need.

How do I download the invoice as a PDF?

Tap Download PDF and choose Save as PDF as the printer. On an iPhone, use the Share button in the print screen and choose Save to Files. The invoice is formatted to fit an A4 page.

I send invoices every week. Is there something better?

Yes — our Invoice & Billing Software (₹15,000 first year) saves customers and products, tracks payments and dues, sends invoices on WhatsApp and gives your customers their own login.

We build billing, stock and business software for small businesses — set up around how you work, with no monthly per-user fees.
