What is subcontract billing software for construction?

Subcontract billing software for construction is an ERP module that manages the complete billing lifecycle between a main contractor and subcontractors — from creating BOQ-linked work orders to raising Running Account (RA) bills, applying GST, TDS and retention deductions automatically, obtaining multi-level digital approvals, and closing the final account with full reconciliation.

What is a Running Account (RA) bill in construction?

A Running Account bill is a periodic payment claim raised by a subcontractor for work completed up to a certain date. It includes cumulative quantities measured, rate per BOQ item, gross amount, and deductions for advance recovery, retention, TDS, and GST. SAZS Apps calculates all these automatically from the work order terms.

How does SAZS Apps handle TDS and GST on subcontractor bills?

SAZS Apps automatically calculates TDS under Section 194C of the Income Tax Act, GST under the Reverse Charge Mechanism (RCM) where applicable, and GST TDS as per the GST Act on every subcontractor bill. Deductions are applied at the configured rates and posted directly to the relevant ledgers without manual entry.

What is a digital measurement book in SAZS Apps?

A digital measurement book in SAZS Apps replaces the traditional paper MB. Site engineers record measured quantities against each BOQ item on the system. The software validates that quantities do not exceed the work order sanctioned limits, and the measurements form the basis for generating RA bills — eliminating manual errors and creating a clear audit trail.

Can SAZS Apps manage subcontract billing for UAE construction projects?

Yes. SAZS Apps supports UAE-specific requirements including UAE VAT at 5%, Wage Protection System (WPS) integration, FIDIC-based contract billing structures, and multi-currency. Contractors operating in Dubai, Abu Dhabi, Sharjah, and across the UAE can manage their subcontractor billing from the same platform used for Indian projects.

How does the multi-level approval workflow work for RA bills?

SAZS Apps provides a configurable approval workflow where an RA bill moves from the site engineer for measurement verification, to the project manager for review, to the accounts team for financial checks, and finally to management for payment authorisation. Each stage is digitally signed with a full audit trail of who approved what and when.

Does SAZS subcontract billing integrate with the accounts module?

Yes. Every approved subcontractor payment automatically posts the corresponding purchase, GST, TDS and cash-flow entries to the accounts module. Project cost reports and cash-flow forecasts update in real time — there is no double data entry between the billing and accounts teams.

What happens at final settlement in SAZS subcontract billing?

At final settlement, SAZS Apps generates a complete reconciliation of all RA bills raised, advances paid and recovered, retention deducted and to be released, and the net amount payable to the subcontractor. All ledger entries are automatically posted and the work order is closed with a full financial history.
