GST returns in Kolkata
Kolkata's business fabric is generational — trading and distribution firms where the books have often lived with one munim for decades. Moving to a verified accountant doesn't mean losing that continuity: you book the same professional recurringly, and every visit ends with a client walkthrough and sign-off on the portal.
Kolkata's family-run trading and distribution firms file on both cadences — regular monthly GSTR-1/3B and QRMP where turnover allows. Whichever applies to you, the accountant matches your books to the e-invoice portal before anything is filed for a Kolkata GSTIN.
Older books usually mean backlog, and backlog is priced honestly here: the engine adds catch-up effort month-by-month for pending periods (bulk catch-up beyond three months is rated cheaper per month), so a Kolkata firm that is six months behind sees the real cost of getting current — once, upfront.
₹1,800/day
A typical standalone engagement is 2 accountant-days a month — ₹3,600/month at the standard tier.
The same engine prices every city — what changes your quote is scope, volume and backlog, not the pin code. On-site visits in Kolkata add a flat ₹300/day.
