GST billing software that files as cleanly as it bills
HSN and SAC codes on every line, the right CGST, SGST or IGST split worked out automatically, credit notes that actually adjust your returns, and a monthly export your accountant can use as is.
Built around how GST actually works
Not a billing app with a tax field bolted on. Place of supply, input credit, credit notes and HSN summaries are part of the core.
Compliant tax invoices
Every bill carries your GSTIN, a continuous invoice series, place of supply and the full tax breakup a GST invoice needs.
- GSTIN on every invoice
- Continuous invoice series
- Place of supply logic
- Bill of supply for exempt sales
HSN and SAC mapping
Assign an HSN or SAC code once per product and it flows into every invoice and tax report from then on.
- Per product HSN / SAC
- Bulk code assignment
- Code shown on invoice
- HSN summary report
CGST, SGST and IGST
The correct split is applied automatically from the customer's state, so intra state and inter state sales are never mixed up.
- Automatic state detection
- Intra and inter state split
- Cess support
- Rate slabs 0 to 28 percent
GSTR ready exports
Pull a month of sales into the summary your accountant or filing portal expects, without rebuilding it in Excel.

Credit and debit notes
Handle returns and corrections properly with linked credit notes that adjust both the ledger and the tax report.

Purchase and input credit
Record supplier invoices with their tax, so input credit is visible next to your output tax instead of sitting in a folder.

Customer GSTIN records
Store a GSTIN against each business customer so B2B invoices are complete the first time.

- B2B invoice flagging
- Billing and shipping address
- Purchase history
Tax dashboard
See output tax, input tax and net liability for the period at a glance instead of waiting for filing week.

- Rate wise breakup
- Period comparison
- Drill down to invoice
One export instead of three days of spreadsheets
Sales register, HSN summary and purchase register come out of the same data you already billed on. No re-entry, no reconciling a counter notebook against a spreadsheet the night before filing.
Frequently asked questions
What makes an invoice GST compliant?+
A GST tax invoice needs your GSTIN, a continuous serial number, the invoice date, customer details with GSTIN for B2B sales, the HSN or SAC code for each item, the taxable value, the applicable CGST and SGST or IGST rate and amount, and the place of supply. Webilns fills all of these automatically once your business and product details are set up.
Does Webilns decide between CGST/SGST and IGST on its own?+
Yes. The split is worked out from your registered state and the customer's place of supply. A sale inside your state is split into CGST and SGST, and a sale to another state is charged as IGST.
Can I export data for GSTR filing?+
You can export a monthly sales register with a B2B and B2C split, an HSN wise summary and a purchase register, in CSV or Excel. Most accountants can take these straight into a filing tool or the GST portal.
How do I handle a sales return under GST?+
Raise a credit note linked to the original invoice. Webilns returns the stock, adjusts the customer ledger and reflects the reversal in the tax reports for that period.
Do I need GST billing software if I am not registered yet?+
No, and you can still use Webilns. Bills go out as a regular invoice or bill of supply. When you register, add your GSTIN and tax rates and the same system starts producing tax invoices.
What does GST billing cost with Webilns?+
GST invoicing, HSN mapping and tax reports are included in plans starting at ₹1,000 per year. There is no per invoice charge and no commission on sales.
