GST invoices when buying from suppliers: what to check

When your business buys from suppliers, the GST invoice is more than a bill — it is what your accountant uses to claim input tax credit and keep your records straight. A small mistake on an invoice, such as a wrong GSTIN, can mean follow-ups, delays or lost credit. A quick check when the invoice arrives prevents most problems.

This is general guidance for buyers; for rules that apply to your business, speak to your chartered accountant or tax consultant.

Give your details correctly before ordering

Share these with the supplier in writing when you place the order:

• Your registered business name, exactly as on your GST registration
• Your GSTIN
• Billing address and, if different, delivery address

Most invoice errors start with details given verbally or in a hurry.

Check the supplier's details

• Supplier's name, address and GSTIN are printed.
• You can verify a GSTIN on the official GST portal to confirm it is active and matches the business name.

Check the invoice content

1. Invoice number and date
2. Description of goods or services matching what you ordered
3. HSN or SAC codes for the items
4. Quantity, rate and taxable value
5. Tax type — CGST and SGST for supplies within your state, IGST for supplies from another state (your accountant can confirm what applies)
6. Tax amounts and total adding up correctly

Match invoice to delivery

• Compare the invoice with the delivery challan and what actually arrived.
• Short supply, damaged goods or wrong items should be raised immediately, so the supplier can issue a correction.

Keep records organised

• Send invoices to your accountant promptly, not at the end of the quarter.
• Ask your accountant how they check that supplier invoices appear in your GST records, and flag mismatches early.
• Keep copies with the purchase order, delivery challan and payment proof.

Choose suppliers who invoice properly

A supplier who issues correct GST invoices without being chased is usually well organised in other ways too. On Bzaro you can mention in your requirement that you need a GST invoice, so suppliers know up front.

Mistakes to avoid

• Accepting invoices in a personal name. For business purchases, the invoice should be in your business name with your GSTIN if you plan to claim credit.
• Waiting until the quarter ends to check. Errors are easiest to correct soon after the sale.
• Paying in cash for large purchases without a proper invoice. It weakens your records and your ability to raise a claim if goods are faulty.
• Mixing up billing and delivery addresses. When they differ, make sure both are shown correctly.

What to include in your enquiry

• Your GSTIN and billing details
• Whether you need a GST invoice (for business purchases, you usually do)
• Delivery address, if different from billing

Browse verified suppliers, or post your requirement and mention that you need a GST invoice.
