Running bills, variation statements, measurements, and PDF reports
Material purchase, issue, transfer, inventory, and stock reports
Vendor, subcontractor, staff, and equipment payment tracking
Approval workflows, WhatsApp sharing, and role-based access
From measurement book to RA bill
Measurements are kept under the schedule and item number of the agreement, with count and dimensions. The RA bill brings them in, carries the previously billed quantity for every item and shows the percentage of agreement used.
If the measurements were recorded in the railway measurement book first, its PDF can be imported into the bill. Quantities brought forward from earlier MBs are checked against what earlier bills already claimed.

Railway rules worked out on every bill
- SOP 2018: 98% of the rate from 125% to 140% of agreement and 96% above, with 200% and 300% limits for items below 1% of agreement value.
- SOR items checked per schedule group, NS items one by one.
- A variation statement without a sanctioned date stops its extra quantity from reaching the bill.
- Income-tax TDS, GST TDS, labour cess and security deposit on each bill, with the net payable at the top.
