What should a retailer send to the accountant every month for GST?

Written by Tax Paramarsh editorial teamReviewed by Tax Paramarsh GST deskLast updated 3 October 2026Applies to: GST rules in force on 3 October 2026

Most late or wrong GST returns start with incomplete data. If you run a shop, send these every month — ideally by the 5th — and your GSTR-1 and GSTR-3B can be prepared on time.

GSTTAX PARAMARSH · ADVISOR’S NOTE

Sales

  • Day-end sales summary from your billing / POS software, by tax rate.
  • B2B invoices with buyers’ GSTINs.
  • Credit notes for returns and exchanges.
  • Marketplace sales and TCS statements, if you sell online.

Purchases

  • All purchase and expense bills with supplier GSTINs.
  • Purchase returns and credit notes received.

Money

  • Bank statement and UPI / card settlement reports — to tie collections to sales.

Good habits

  • Export data straight from your billing software rather than retyping.
  • Update item tax rates whenever the law changes.
  • Ask B2B customers for their GSTIN before billing.

Key takeaways

  • Send sales, purchases and payment data by the 5th.
  • Export from software — don’t retype.
  • Collect B2B buyers’ GSTINs at billing.

Common questions

Is a photo of bills enough?

For purchases, clear photos or PDFs work. For sales, a software export by tax rate is far more reliable than photos.

Why the 5th?

It leaves time to reconcile and fix issues before GSTR-1 is due on the 11th.
