Contractor and vendor bill management
Every subcontractor’s RA bill built from measured work, every vendor bill matched to its order, approved within limits, and paid with the deductions right.

What you can do
Subcontractor RA bills
Previous, this period and cumulative, from the measurement book.
Deductions worked out
Retention, advance recovery, TDS and GST on every bill.
Vendor bills
Supplier bills by vendor and project, through the same approvals.
Approvals
Draft, submitted, approved, rejected and paid, within rupee limits.
Payments
What was paid, when and how, with retention released when due.
Tally export
Bills and payments go to TallyPrime as vouchers for your accountant.
Why it matters: You check the quantities, not the arithmetic, and pay only for work done.
Works with the rest of Mezura OS
Every part shares the same records: a quantity measured on site shows up in progress, the bill and the margin; a delivery recorded against a purchase order updates site stock. Nothing is typed twice.
