GST compliance

GST done right on every document, and ready for your return

SimpleERP gets GST right where it starts, on each invoice and bill, and gives you the registers and summaries to prepare your returns. Filing stays with you and your CA on the GST portal.

In short

SimpleERP is GST compliance software for Indian small businesses. It applies CGST and SGST or IGST by place of supply, carries HSN or SAC codes on every line, and produces GST registers, an HSN summary and an input tax summary. It does not file returns.

What SimpleERP does, and what it does not

A clear line helps you and your CA plan the month. SimpleERP makes sure the tax on each document is right and adds up; the return itself is prepared and filed on the GST portal. It does not file returns, generate e-invoices or e-way bills, or handle cess.

  • GST on every invoice, bill, credit note and debit note, by place of supply.
  • The registers and summaries you check before filing GSTR-1 and GSTR-3B, and compare with GSTR-2B.

On every document

The right tax is decided when the document is made

SimpleERP compares the customer's or supplier's state with your branch's state and applies CGST and SGST for the same state or IGST for another, so nobody picks the tax type by hand.

  • GSTIN validated on every party, with the state taken from it.
  • HSN or SAC code on every line, with an HSN-wise summary on the printed invoice.
  • Tax split per component: CGST, SGST and IGST each post to their own output and input accounts.
  • Invoice numbering on the April to March year, such as INV-2026-27-0213, assigned at save.
  • Posted documents are frozen; a cancellation reverses the tax with everything else.
  • Credit and debit notes carry the tax back, so returns and price changes reduce the tax as well as the amount.

Registers and summaries

The reports you check before you file

Every report below is built from posted documents, filters by period and branch where it applies, and exports to CSV for your CA.

Month end

Lock the month once the return is filed

After you file, set the lock date and the database refuses any posting on or before it, so the books cannot drift away from the return. A bill found after the lock is posted in the open month; ask your CA how to report it.

  • Lock date lists drafts that will fail to post before you confirm.
  • Reversals of a locked month's entry are dated in the open month.
  • CSV exports of every register go to your CA as they are, with no reformatting.
  • Audit log records who changed what, including the lock date.

Honest limits

What SimpleERP does not do for GST

These stay with you, your CA or the GST portal.

  • Filing GSTR-1, GSTR-3B or any other return.
  • E-invoice (IRN) generation through the invoice registration portal.
  • E-way bill generation.
  • Automatic matching against GSTR-2B downloaded from the portal.
  • Cess. There is no cess rate or column today.

FAQ

Questions, answered

Is SimpleERP enough for my GST compliance?

It handles the document side: correct tax on every invoice and bill, and the registers and summaries for your returns. Filing, e-invoices and e-way bills are done outside it. Confirm what applies to your business with your CA.

Does SimpleERP generate e-invoices?

No. If your turnover requires e-invoicing, you would need to generate the IRN on the portal or another tool. Tell us if this matters to you.

How does SimpleERP decide CGST and SGST or IGST?

From the place of supply: the party's state, taken from their GSTIN or address, against your branch's state. Same state gives CGST and SGST; another state gives IGST. Special cases should be checked with your CA.

Can I see my input tax credit?

Yes. The GST summary shows input tax by component and month next to output tax, with the net payable. Match it with GSTR-2B before you claim.

Where can I read the invoice rules?

Our GST invoice format guide lists the mandatory fields with links to the official sources.
