How to Make a GST Invoice

What a GST invoice actually needs

A valid GST invoice for Indian businesses typically includes your GSTIN, the applicable tax rate (5%, 12%, 18%, or 28%), a clear breakdown of taxable value versus tax amount, and sequential invoice numbering. Getting any of these wrong can cause problems with your accountant or during a GST filing.

Step-by-step: creating a GST invoice in Invoiso

1. Add your GSTIN. In your business profile, enter your GST registration number once — it appears on every invoice automatically.
2. Set your default tax rate. Configure the GST rate you charge; you can still adjust it per invoice if needed.
3. Create the invoice as normal. Add your client, line items, and quantities — Invoiso calculates the taxable value and GST amount automatically.
4. Review the tax breakdown. The generated PDF shows subtotal, GST amount, and total due clearly separated, exactly as required.
5. Send it. Share the compliant PDF directly with your client or forward it to your accountant.

Why automatic GST calculation matters

Manually calculating GST across multiple line items with different rates is where most invoicing errors happen. Invoiso applies the rate consistently across the invoice so the numbers your client sees match what you'll report — no mismatches, no rework.

Works for VAT too

If some of your clients are based outside India, Invoiso supports VAT the same way — just switch the tax type and rate per invoice or per client.
