GST return filing, with ITC checked before anything is filed
For monthly filers, GSTR-1 falls due on the 11th and GSTR-3B on the 20th of the following month; QRMP filers upload B2B invoices by the 13th and pay monthly tax by the 25th via PMT-06. A verified accountant keeps every one of those dates, working to a GST SOP that matches sales in your books against the e-invoice portal and GSTR-1 filings — so what is filed is what the books say.
Input tax credit is where GST filing goes wrong quietly: the SOP requires GSTR-2B to be matched against your purchase register before any credit is claimed, and requires your approval on the portal before filing — with the ARN saved to your workspace afterwards. Composition dealers are covered too (CMP-08 quarterly, GSTR-4 annually), as are the annual GSTR-9/9C consolidations where turnover requires them.
₹1,800/day
A typical standalone engagement is 2 accountant-days a month — ₹3,600/month at the standard tier.

Frequently asked questions
Which GST returns can the accountant handle?
Regular monthly filings (GSTR-1 and GSTR-3B), the QRMP scheme for turnover up to ₹5 crore (IFF invoice upload, PMT-06 monthly payments, quarterly GSTR-3B), the composition scheme (CMP-08 quarterly and GSTR-4 annually), and annual returns (GSTR-9, with GSTR-9C reconciliation above ₹5 crore turnover).
Do you verify input tax credit before filing?
Yes — it is a mandatory SOP step: GSTR-2B is matched with the purchase register before ITC is claimed, sales in the books are matched with GSTR-1 and the e-invoice portal, and nothing is filed without your approval recorded on the portal.
