- RA (running account) bills are how construction gets paid in stages — and they're easy to get wrong.
- Retention, mobilisation advance, deductions and works-contract GST all stack on one bill.
- Software that automates RA billing protects your cash flow and your margins.
In construction, you rarely bill once — you raise running account (RA) bills as work progresses, each carrying retention, advances, deductions and works-contract GST. Do it by hand and errors creep in that delay payment or quietly cost you money. RA bill software gets every stage right.
Why RA billing is easy to get wrong
Each RA bill builds on the last — cumulative quantities, previous payments, retention held, advance recovered, and GST/TDS. Miss one adjustment and either you under-bill (losing money) or over-bill (disputes and delays).
What RA bill software handles
- Measurement-based running account bills with cumulative tracking
- Retention money held and released per terms
- Mobilisation advance and its recovery schedule
- Works-contract GST (18%) and TDS deductions
- Subcontractor bills mirrored against client bills
- Bill-wise outstanding and payment follow-up
Clean, accurate RA bills get certified and paid faster. In construction, faster certification is often worth more than any discount.
Built around your contract formats
Government, PWD, private and infrastructure contracts each have their own bill formats and deduction rules. Wizix builds RA billing tailored to your contracts — so bills go out in the exact format your clients certify, with retention and GST always correct.
Does it handle retention and advance recovery automatically?
Yes — retention is held and released per your terms, and mobilisation advance is recovered on the schedule you set, across successive RA bills.
Can it mirror subcontractor bills to client bills?
Yes, so you can see the margin on each item and stage, not just the top-line bill.
