Getting paid in Indian construction is a chain — and it breaks link by link
In Indian construction, getting paid isn't one event — it's a chain: you measure work, value it against a BOQ, raise a Running Account bill, deduct retention, apply GST, submit before the cut-off, get it approved, and eventually receive payment (often late). Each link has its own failure mode, and a break anywhere costs money — a mis-measured quantity, an outdated rate, a missed retention, a GST error, a bill that reconciles to nothing. Master the chain and you get paid faster, fuller and with fewer disputes.
This guide walks the whole chain and links to the depth behind each link. It's written for the Indian reality of RA billing, BOQ item rates, retention and GST — not generic invoicing.
The links in the billing chain
Measurement
The quantity of work done — the origin of every rupee you bill.
BOQ & work orders
The rates your work is valued at — the price side of the bill.
RA billing
Running-account bills with previous-vs-current and retention.
GST
CGST/SGST/IGST, SAC and RCM applied correctly.
Cash flow
Receivables, payables and forecast — the money picture.
Traceability
Every figure linked back to its source for audit.
1. Measurement and BOQ — the two sides of every bill
A bill is quantity times rate. Quantity comes from measurement recorded on site; rate comes from your BOQ and work orders. If either is loose, the bill is wrong before you start. Keeping both digital and linked means the bill is derived, not typed — which removes the single largest source of billing disputes.
2. RA billing and retention — the Indian way of billing
Most construction is billed on Running Account: you bill the difference between cumulative value now and what was billed before, holding back retention. This is where spreadsheets fail most — carrying previous quantities forward, deducting retention correctly, never double-billing. RA bill software makes each of these automatic. (New to it? See the difference between a work order and a BOQ.)
3. GST — compliance built into the bill
Construction GST is CGST/SGST vs IGST by place of supply, the right works-contract SAC, RCM where it applies, and tax interacting with retention. Handle it with GST billing built for contractors so it's compliant by construction, and check any figure fast with the free GST calculator.
4. Cash flow — the point of it all
Billing correctly is only worth it if you can see and collect the money. Cash-flow software shows what you've billed, received and are still owed, and forecasts what's coming — so slow payments are visible and chased, not discovered at quarter-end. When the whole chain lives in one construction billing platform, raising a bill updates your receivables and forecast automatically.
The through-line: derive the bill from the work, apply Indian rules automatically, and see the money in real time — that's how you get paid right and stay compliant.
Billing, cash flow & compliance — FAQs
How does construction billing work in India?
Typically on a Running Account basis: you measure work done, value it against BOQ rates, bill the difference over the previous bill, deduct retention, apply GST (CGST/SGST or IGST), and submit for approval and payment. Each step depends on the one before, so accuracy at measurement and BOQ is essential.
What is retention and how is it handled?
Retention is a percentage held back from each RA bill as security, released later per the contract. It must be deducted correctly on every bill and never doubled or missed — something RA bill software applies automatically at your configured percentage.
What GST rules apply to construction billing?
CGST/SGST for intra-state and IGST for inter-state supply, the correct works-contract SAC code, Reverse Charge Mechanism where applicable, and correct interaction of tax with retention on RA bills. Getting these right keeps invoices compliant and preserves input credit.
Why do contractors struggle with cash flow?
Because payments are slow and visibility is poor — billing sits in one place, receipts in another, and outstanding amounts aren't tracked live. Cash-flow software that shows billed, received and outstanding in real time lets you chase money before it becomes a crisis.
Can one platform handle the whole billing-to-cash chain?
Yes. True Site Sync links measurement, BOQ, RA billing, GST and cash flow, so a bill is derived from the work, Indian rules are applied automatically, and receivables update in real time. It starts at ₹2,500/year with a free trial.
Does it work offline on site?
Yes. It is offline-first, so measurements and billing data are captured on site with no signal and sync when you reconnect.
Our billing, GST and cash position lived in three different places and never agreed. Once the whole chain — measurement to RA bill to GST to cash — was one system, our bills stopped getting queried and I could finally see what every client actually owed. We get paid faster now.
