Free GST invoicing software: what to actually check before signing up

Free plans in this category are rarely free in the way the label implies. Most cap the number of invoices, remove your branding in favour of the vendor watermark, or lock GST fields like HSN codes and tax splits behind a paid tier — the exact fields a compliant invoice needs.

Check what counts against the free limit

A generous-sounding number of free invoices means little if drafts, edits, or resends each count against it. Ask specifically whether the limit is invoices created or invoices sent, and whether it resets monthly or is a lifetime cap.

Confirm GST fields are not paywalled

• GSTIN field for both your business and the client
• HSN or SAC codes per line item
• Automatic CGST, SGST, or IGST split based on place of supply
• A sequential invoice numbering series you do not have to manage by hand

Look at what happens after the invoice is sent

Creating the invoice is the easy half. The tools that save real time are the ones that also chase the payment — reminders, a payment link, and a record of what is still outstanding — rather than leaving that entirely to you once the PDF is out the door.
