Client RA bills and GST invoicing
Everything measured since the last bill goes on the client’s RA bill, with GST, retention and TDS worked out, as a tax-invoice PDF, and you see what is still owed.

What you can do
RA bills from measurement
Previous, this bill and to date, from the quantities measured on site.
GST tax invoices
CGST and SGST, or IGST, picked from both parties’ states, as a PDF with the measured abstract.
Retention and TDS
Retention, TDS and GST-TDS for government clients worked out on every bill.
Payments tracked
Sent, part paid, paid and overdue, with what the client is holding back.
Retention release
Retention held by each client, and when it is due back.
Tally export
Client bills and receipts to TallyPrime as vouchers.
Why it matters: The bill goes out the week measurement closes, and nothing owed is forgotten.
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.
