GST invoices for online sellers

Flowgento raises the GST tax invoice the moment you mark an order shipped — numbered in one gapless series for your shop, with the right tax split for where the customer is.

How it works

  1. Set your GSTIN, state and each product's HSN code and GST rate.
  2. A customer orders; the price and the tax are worked out at checkout.
  3. You mark the order shipped — the invoice is created and numbered then.
  4. Refunds and cancellations after shipping raise a credit note; both feed GSTR-1.

On every invoice

  • Your legal name, GSTIN, address and the invoice number from a gapless series.
  • Each line with its HSN code, GST rate and taxable value; CGST and SGST within your state, IGST outside it.
  • The buyer's GSTIN and business name when they order for a business (B2B).
  • Delivery and COD charges taxed like the goods, at the rate you set.

When things change

  • A refund or a cancellation after shipping raises a credit note, never a deleted invoice.
  • Customers download their invoice from the order page or the signed order-status link.
  • Invoices and credit notes go straight into GSTR-1 and into your books.

Questions sellers ask

Why is the invoice made at shipping and not at the order?
A supply happens when goods leave you. Orders cancelled before shipping never get an invoice, so the series stays clean.
Can a customer get a B2B invoice?
Yes. They enter their GSTIN and business name at checkout, and the invoice carries them.
Can I delete an invoice?
No — an issued invoice is never deleted. A cancellation or refund raises a credit note, as GST rules require.
Does Flowgento create e-invoices (IRN)?
No. E-invoicing and IRN are not offered.

Selling on marketplaces too? Make one GSTR-1 from your Amazon, Flipkart and Meesho reports.
