What ContractBill does

ContractBill makes the RA Bill for a government work from the DSR rate book. You send the papers you already have, check the lines instead of typing them, and download the bill in your department's own format with the formulas live in it.

Checked against ContractBill on 12 October 2026

A bill is a small book of sheets that all depend on each other: the Schedule of Work, the measurements, the Abstract, the Cement statement and the rest. Every rate on it has to match the rate book to the paise, and the AE checks every line by its S.No. ContractBill keeps all of those sheets in step for you.

The 3 steps

  1. Send the Schedule of Work. A photo of the paper is enough. Send the award letter with it and your bill gets your details printed on it.
  2. Our AI reads and matches. Every item code is matched to the DSR as mentioned in your schedule. The rate comes from the DSR book, never from the photo. Anything it cannot match is marked for you to cross verify.
  3. Verify and get the bill. Confirm the lines. Schedule of Work, Measurement, Abstract and Cement Statement come out together, in Excel in your department format.
