Bill by a project and its bill of resources — labour, machine and material — not by product SKU. Raise GST-compliant RA and progress bills as work advances, handle retention and advance, and post to your accounts. Construction and project firms are one of the businesses Fast Billing serves — it runs all GST billing, cloud or on-premise, across India and worldwide.
Standard invoicing wants a product and a quantity, but you bill a stage of work — an RCC frame, a plumbing package — measured in labour, machine and material. Forced into product lines, the bill loses the story the certifier needs.
Each running-account claim is retyped from measurement sheets into a fresh invoice, and the client's certifier disputes lines that don't tie to the resources and stage actually done on site.
The held-back retention and the mobilisation advance live on a side sheet, so the net payable on each RA bill is a manual sum nobody trusts and retention due for release quietly slips off the radar.
Project bills, GST and receipts are re-keyed into accounting by hand, so GST output and the outstanding on each project drift out of sync and month-end becomes a reconciliation hunt.
Every project bill follows the same controlled path, whatever the site delivers — so billing runs on a project and its bill of resources, not on measurement sheets and a side ledger for retention.
Fast Billing gives construction and project firms the billing control they keep trying to build with measurement sheets and a side ledger — with GST, retention and accounts posting built in.
For construction, real-estate, EPC, fabrication and job-work firms, a bill isn't a product and a quantity — it's a stage of work. Project & resource billing raises a bill against a project and its resources rather than a SKU. Set the project up once with its client, GST number and budget, and every bill you raise against it — progress or running-account — carries the resource detail the certifier expects. It's one system that also raises standard GST tax invoices and counter POS for your product sales.
Each project bill breaks down into a bill of resources — the labour, machine and material a stage consumed — priced with a quantity and a rate. So an RA bill for a floor's RCC shows the ready-mix concrete, the steel, the mason gang and the plant as separate lines, not one opaque lump sum, and it ties back to the project costing and your accounts and vouchers. That's the detail that gets an RA claim certified without a fight.
Every project bill is a proper GST document. HSN and CGST/SGST/IGST come from the tax configuration and the item and party tax maps, freight, packing and other charges are added, the total is rounded and the amount is converted to words on the printed bill. Whether the client is in-state or inter-state, the split is right — and the GST tax invoicing engine and the e-way bill and e-invoice handoff are the same ones your product invoices use.
Construction bills rarely settle at face value. Apply retention (a held-back percentage) and adjust the mobilisation advance on the bill itself, so the net payable is right the first time. Record the client's receipt against the bill through payments, receipts & follow-up, adjust any advance, and the outstanding — including retention due for release — is tracked per project, with SMS, email and WhatsApp follow-up on overdue RA dues.
A confirmed project bill posts as a sales voucher with GST to Tally and other tools, and receipts post as receipt vouchers, so your GST output and project outstanding stay in step without re-keying. Sales returns and rate corrections go through credit and debit notes, light accounts, vouchers and expenses keep C-Form, budgets and supplier bills in one place, and Dhruv AI answers "which projects have the most outstanding?" in plain English. It's one system that also runs your standard GST tax invoices and counter POS.
