GST vs Non-GST Invoices: Which One Should You Send?
A quick guide to choosing the right invoice type for every client.
Most print shops serve two very different kinds of customers on the same day: a walk-in who wants 500 visiting cards by evening, and a corporate client who needs a proper tax invoice for their accounts team. Sending the wrong invoice type to either one causes real problems — a business client can't claim input tax credit without a valid GST invoice, and slapping tax onto a casual retail bill just confuses everyone. Here's a simple way to decide which invoice to send, every time.
GST invoice vs. Non-GST invoice, in plain terms
A GST invoice (technically a "tax invoice") is a formal bill that separately shows the taxable value of the goods or services and the GST charged on top, broken into CGST/SGST or IGST as applicable. It includes both parties' GSTIN, an HSN/SAC code for what was supplied, and a sequential invoice number from your GST invoice series.
A Non-GST invoice (often just called a bill or a "bill of supply") is a simpler receipt — item, quantity, rate, total — with no tax breakup. It's what you'd hand a walk-in customer buying a few prints, or what a business not registered under GST would issue.
| Non-GST Invoice | GST Invoice |
|---|---|
| No GSTIN required from either side | Your GSTIN (and ideally the client's) is on the invoice |
| No tax breakup shown | Shows taxable value + CGST/SGST or IGST separately |
| Simple sequential numbering | Must follow your GST invoice numbering rules |
| Client can't claim input tax credit | Client can claim input tax credit (if eligible) |
When you should send a GST invoice
- You're registered under GST and the sale is a normal taxable supply — this is the default once you cross the registration threshold or have opted in voluntarily.
- The client is a business with a GSTIN and asks for one — usually because they need to claim input tax credit on the printing expense.
- The order is B2B or bulk — corporate stationery, packaging runs, agency work — where a proper paper trail matters for both sides' books.
When a Non-GST invoice is enough
- You're not registered under GST — for shops below the registration threshold, a simple bill of supply is the correct document, not a tax invoice.
- A casual walk-in retail sale — a student printing an assignment or someone collecting a few photo prints rarely needs a tax invoice.
- The client explicitly doesn't need one — some individual clients just want a receipt for their own record, not a compliance document.
What to double-check before you hit send
1. Is your GSTIN correct on every GST invoice?
A typo here can block your client's input tax credit claim entirely — it's the single most common error print shops make when billing manually.
2. Are you using separate numbering series?
GST rules expect a distinct, sequential numbering series for tax invoices. Mixing GST and Non-GST invoices into one running number makes reconciliation messy at filing time.
3. Does the client's GSTIN actually match their business name?
Worth a quick check before the invoice goes out, especially for new clients — an invoice with a mismatched GSTIN is often rejected by the client's accounts team and comes back for a correction.
How PrintKhata handles this for you
Instead of deciding all of this manually on every order, PrintKhata lets you create both GST and Non-GST invoices from the same screen. Search for the client, pull in the goods, and the amount — and GST, where applicable — is calculated automatically. The invoice is emailed straight to the client, and every invoice is filterable later by name, contact, invoice number, or date range, so nothing gets lost between the two invoice types.
