Example: a filled invoice
- The title says what the document is: an invoice.
- A unique number from a continuous series, allocated when you issue it.
- Your name, address and GSTIN.
- Who it is for.
- Each line: description, HSN/SAC, quantity, rate and taxable value.
- GST split by component: CGST and SGST in the same state, IGST across states.
- The total in the document's currency and format.
Worked example: the numbers behind the invoice above
| Item | Qty | Rate | Taxable value | Tax |
|---|---|---|---|---|
| LED television 43 inch | 1 | ₹28,500.00 | ₹28,500.00 | ₹5,130.00 |
| Wall mount and installation | 1 | ₹1,200.00 | ₹1,200.00 | ₹216.00 |
| Taxable value | ₹29,700.00 | |||
| CGST 9% | ₹2,673.00 | |||
| SGST 9% | ₹2,673.00 | |||
| Total | ₹35,046.00 | |||
GST is worked out per line and split into CGST and SGST (same state) or IGST (other state) from the two GSTINs.

What to put on an invoice, field by field
| Field | What to enter |
|---|---|
| Document title | Say exactly what it is: "Tax invoice". The title tells the buyer and the tax authority how to treat it. |
| Number and date | A unique number in a continuous series (at most 16 characters, unique for the financial year) and the issue date. LuckPanda allocates the number when you issue. |
| Your business | Name, address and GSTIN (state code is the first two digits) |
| Customer | Name, address and GSTIN if registered; for unregistered buyers, name, address and state |
| Lines | Description, quantity, unit and rate, with the HSN code for goods or SAC for services. Each line carries its own tax rate. |
| Tax | GST rate per line. Same state: CGST and SGST, half each. Another state or export: IGST. |
| Totals | Taxable value, tax by component and the total, in the document currency. Amounts in words are customary in India. |
| Terms | Due date, bank or payment details and late-payment terms. |
India GST rules for an invoice
- Contents are set by rule 46 of the CGST Rules: supplier name, address and GSTIN; a consecutive serial number of up to 16 characters, unique for the financial year; date; recipient details and GSTIN if registered; HSN or SAC; description, quantity, taxable value; rate and amount of CGST, SGST/UTGST or IGST; place of supply for inter-state supplies; a reverse-charge statement where it applies; and a signature.
- HSN digits: businesses with aggregate turnover up to ₹5 crore show 4 digits on B2B invoices; above ₹5 crore, 6 digits on every invoice.
- Timing: for goods, on or before removal or delivery; for services, within 30 days of supply.
- E-invoicing (an IRN from the Invoice Registration Portal) applies to B2B invoices of businesses whose aggregate turnover crossed ₹5 crore in any year since 2017-18.
- Unregistered or composition sellers do not issue tax invoices: they issue a bill of supply and charge no GST.
Mistakes to avoid
- Editing or deleting an issued invoice instead of issuing a credit note.
- Gaps or duplicates in the number series.
- Charging the wrong tax type (for India: IGST on an intra-state sale, or CGST and SGST across states).
- Leaving out the due date and payment details, which is the commonest reason invoices are paid late.
- Rounding each line's tax differently from the total; LuckPanda computes tax per line and keeps the components adding up.

| Credit note | After an invoice, to reduce it | No, reduces what is owed | Yes | Yes: reverses part of the sale |
