SmartBiz helps you generate GST-compliant invoices automatically for your online orders. Once you set up your GST details in tax settings, invoices will be created for orders and can be downloaded by you and your customers.
Step 1 — Enter Your GST Details
Go to Settings > Tax in the SmartBiz dashboard and fill in:
GST No: Your GSTIN (GST Identification Number)
State Code & Name: Automatically captured from your GSTIN
Business Registered Name: The legal business name linked to this GST
Business Registered Address: The official address under this GST
Default Tax Rate: Tax % applied to products when no specific HSN/tax is entered
Note:
An HSN Code (Harmonized System of Nomenclature) is a standard classification used under GST to identify the type of product being sold and its applicable tax rate. If you’re unsure about the correct HSN code for your product, you can refer to the following List of HSN Codes, your GST registration documents, past GST returns, or consult your tax advisor. If no HSN code is added at the product level, SmartBiz applies the default tax rate you set here.
Step 2 — How Invoices Are Created
Once GST details are enabled:
SmartBiz will generate a GST invoice automatically after you ship an order
You and the buyer can download the invoice anytime from the order details

FAQs:-
1. When is the GST invoice created?
The invoice is created automatically when you click Ship order in the Order Management System. It may take about 5–10 seconds after clicking before the invoice appears. You can also open it from the three-dot menu next to each order.
2. Can I delete or edit an invoice once it’s generated?
No — once an invoice is generated, it cannot be deleted or modified in SmartBiz. If you need a corrected invoice, you should issue and keep a separate invoice outside SmartBiz.
3. Do I need GST to use this feature?
Yes — you must enter a valid GSTIN to enable GST invoice generation. Without GST details, SmartBiz will not create GST invoices.
4. What happens if my GST details are incorrect?
If your GSTIN, business name, or address is not entered correctly, the invoice will contain the wrong information. This could cause issues in tax filings. Always double-check the details before saving.
5. What tax rates should I set?
Set the default tax rate that usually applies across your catalogue. If specific products have different GST rates, update those with HSN/tax rate in product setup.
6. Will SmartBiz calculate IGST/CGST/SGST automatically?
Yes — the system applies the correct tax structure (IGST vs CGST/SGST/UTGST) based on your store location and the buyer’s address.
7. Why doesn’t my customer see a GST invoice?
If your store GST settings were incomplete when the order was placed or shipped, SmartBiz won’t generate an invoice. Make sure your GST details are added before orders are shipped.
8. Can I use these invoices for GST filing?
Yes — the GST invoice generated can be used as a valid commercial tax invoice for compliance and filing purposes, provided details are accurate.
