GST Billing Software for Amazon Sellers in India

Amazon.in makes selling easy and GST compliance surprisingly hard. Every order you ship is a taxable supply in your name, so the tax invoice is your legal document even when Amazon prints it under its Invoice-by-Amazon programme. When a customer in Kerala buys from your Delhi FBA stock, the place of supply, the IGST split and the invoice series all have to be right in your books, because your GSTR-1 is what the department reads.

Then there is the marketplace layer on top. Amazon deducts TCS at 1 percent on your net taxable sales and files it against your GSTIN. Amazon charges you referral fees, closing fees, FBA fees and advertising, each with 18 percent GST that you are entitled to claim as input tax credit, but only if the fee invoices are in your name and match what appears in your GSTR-2B. Returns come back as refunds that need credit notes, not deleted invoices. Miss any of these and the mismatch notice arrives months later.

We built myBillPlease around this exact workflow. Our Shopify integration came first, and the Amazon Seller Partner API connection followed because the same sellers asked for it. This page explains how the pieces fit, what we automate, and what you still have to check yourself.

Three decisions at setup save most of the trouble later. Invoice series. GST allows up to 16 characters and requires a unique, consecutive series per financial year. We suggest a prefix that names the channel, such as AMZ/26-27/0001, so an Amazon invoice is recognisable in your register and in an audit. Keep a separate series per GSTIN if Amazon holds your stock in more than one state.

GSTINs and places of business. Add every state where you hold FBA inventory as a place of business, each with its own GSTIN, series and return set. Stock transfers between your GSTINs are taxable supplies at the item's rate and need an e-way bill above Rs 50,000; myBillPlease raises the transfer invoice and the e-way bill from the same record.

Product master. Give every SKU its HSN code, rate and unit before the first sync. Amazon's catalogue data does not carry your HSN, and a wrong rate on the master repeats itself on every invoice. Use our HSN code finder to check codes, then lock the master. Rate changes under GST 2.0 are applied by effective date, so an invoice dated before the change keeps the old rate.

With those three in place, the monthly cycle above is mostly review: read what synced, credit-note the returns, record the fee invoices, reconcile, file.

Here is the cycle we see working sellers run every month, with what myBillPlease does at each step.

Week 1: orders become invoices. The SP-API sync brings in the previous period's orders. Each one is invoiced in your numbering series, with the buyer's state deciding whether the tax is CGST plus SGST or IGST. If you ship from FBA warehouses in several states, register each warehouse state as a place of business and keep a separate series per GSTIN; we let you run multiple GSTINs under one login.

Week 2: returns and replacements. Amazon's returns report lists refunded orders. Each refund becomes a credit note linked to its invoice, reducing your taxable value for the month rather than silently vanishing. Replacements that ship a new unit get a fresh invoice.

Week 3: fees and input credit. Download Amazon's fee tax invoices from Seller Central. Record them as purchase invoices so the 18 percent GST on referral, closing, FBA and advertising fees shows up as ITC. Match them against your GSTR-2B before claiming; anything Amazon has not reported yet stays in the pending column.

Week 4: TCS and the return. Amazon files GSTR-8 with your TCS. Accept the credit on the portal, then reconcile the marketplace sales they reported with the invoices in myBillPlease. Differences usually come from cancelled orders or timing. File GSTR-1 by the 11th and GSTR-3B by the 20th using the tables myBillPlease fills for you. Our blog guides on GSTR-1 and GSTR-3B walk through each table if you file on the portal yourself.

One thing we do not do: we do not fetch Amazon's fee invoices or TCS statements for you. Those still come from Seller Central, and we tell you so up front rather than promising an integration that does not exist.

Amazon's reports are accurate about what Amazon did, and silent about what you must file. They do not produce your invoice series, your credit notes or your GSTR-1 tables. Treat them as the source you reconcile against, not as your books.

Excel works until the first month with returns. Formulas drift, series break when two people edit, and the HSN summary takes an afternoon. We wrote a comparison of Excel and GST billing software that goes into the real costs.

Tally is excellent accounting software and knows nothing about Amazon orders unless you import them. Sellers who already run Tally often keep it for accounts and use myBillPlease for order invoicing, exporting the sales register monthly. See our Tally comparison for where each fits.

The honest summary: if you sell on Amazon and have no accountant on staff, a tool that reads your orders, writes compliant invoices and fills the return is the difference between filing in an hour and filing in a weekend.
