Turnover Certificate in Kolkata

West Bengal tenders: two portals and a three-year average

State procurement in West Bengal runs online. A Finance Department memorandum made e-tendering through the state portal, wbtenders.gov.in, mandatory for government procurement of ₹5 lakh and above. Since then the state has moved to a newer portal, tenders.wb.gov.in, and by a Finance Department memo of 12 August 2026 the Public Works, Public Health Engineering, Panchayat and Rural Development, Irrigation and Waterways, and Health and Family Welfare departments, along with all District Magistrate and Zilla Parishad offices, float fresh e-tenders only on the new portal. Check which portal your notice is on; the turnover clause itself does not change with the portal.

What does vary is the wording. A West Bengal works tender usually asks for an average annual turnover over a stated number of financial years, often three, against a minimum the notice sets, and asks for the supporting document to be uploaded with the technical bid. Some say "as per audited accounts"; some ask for a CA certificate; some want both. We draft to the exact words in your notice, show each year's figure and the average, and name the records relied on, so the evaluation committee does not have to calculate anything or guess the basis.

The same applies to central buyers with offices in Kolkata. Suppliers to railways, ports and central PSUs bid on the central portals, and a GeM bid typically shows the requirement as a "Minimum Average Annual Turnover of the bidder" for three years, with audited balance sheets or a CA's certificate accepted as evidence. Micro and small enterprises are often exempted from that criterion in the bid, but the exemption is set bid by bid, so read yours.

The reconciliation that trips up Kolkata contractors

For a contractor working for government, the figure in the books and the figure in the GST returns rarely match exactly, and evaluators increasingly check one against the other.

The usual reasons are ordinary. Running bills are certified by the department in one month and the GST invoice is raised in another. Retention money and security deposits are deducted from the bill. Government departments deduct TDS under section 51 of the CGST Act and that deduction shows on your GST portal against the contract value they recorded, which may not be the value you booked. Add a year-end bill accounted in March but invoiced in April, and the difference is real but explainable.

We reconcile before we sign. Here is the shape of it, for an illustrative Kolkata civil contractor:

The certificate reports the figure the tender asked for, usually the audited ₹412.0 lakh, and the reconciliation sits in our file in case the evaluator queries it. If the tender asks for turnover as per GST returns instead, the certificate says so and reports ₹402.0 lakh. Either way, the number on the page is one a record supports.

Banks and MSME status in West Bengal

Cash credit and overdraft limits for Kolkata traders are typically sized on sales, so at renewal a bank may ask for certified turnover for the year just ended before the audit is done. That certificate is drawn from the books and the GST returns and says it is unaudited. Where the bank wants projected turnover and a working capital computation rather than a single figure, that is CMA data, not a turnover certificate.

For MSME schemes and Udyam classification, remember that exports are excluded from turnover. A Kolkata tea or jute house with export sales can have revenue well above the micro limit and still be micro on the MSME basis. Update your Udyam registration first if the figures have moved.
