Track BOQ vs actual costs across every project, manage milestone billing with retention, control subcontractor POs and TDS, monitor multi-site material movement, and stay RERA and WPS compliant — all in one integrated ERP. Implemented by Quantbit for contractors across Maharashtra, UP, and Karnataka.
Construction is the industry where cost overruns are discovered after the project is complete — because most companies lack real-time visibility into what was spent vs what was budgeted. ERPNext changes that.
Project managers learn that a site has exceeded its material or subcontractor budget only at project closure — when it's too late to course-correct. Spreadsheet-based tracking has a 2-to-4-week lag from site reality.
Retention receivables — often 5–10% of contract value — are tracked in spreadsheets and frequently missed at release date. Uncollected retention from completed projects sits as forgotten receivables that quietly age into bad debt.
Subcontractor invoices arrive without corresponding POs, claims are paid without verifying work completion, and TDS is either not deducted or calculated incorrectly — leading to both financial loss and income tax notices.
Material issued to sites without systematic tracking leads to pilferage, double-ordering, and inventory sitting idle at one site while another site waits for the same material causing delays.
From residential builders in Maharashtra to EPC contractors in Karnataka and infrastructure companies in Uttar Pradesh — ERPNext is configured to the specific workflows of each construction segment.
RERA designated account tracking, milestone billing linked to possession stages, buyer payment schedules, and project-wise cost centre P&L for developers building housing projects and townships.

Construction services attract 12% GST for affordable housing and government contracts, and 18% for commercial construction. ERPNext applies the correct rate per contract type — with ITC reversal rules for residential projects where applicable.
TDS at 1% (individual subcontractors) or 2% (company subcontractors) is deducted automatically in ERPNext on every subcontractor payment. Quarterly TDS returns (24Q) and Form 16A certificates are generated directly from the system.
RERA mandates 70% of project collections be maintained in a designated project bank account. ERPNext's project-wise accounting tracks fund movements, ensures minimum balance compliance, and generates reports formatted for Maharashtra RERA and other state RERA authority quarterly filings.
GCC countries mandate WPS-compliant salary payment via bank transfer. ERPNext generates the Salary Information File (SIF) per payroll run — ready for upload to the WPS portal via the company's bank, ensuring labour permits and visas remain valid.
Construction companies with site labour are required to contribute to ESI and PF. ERPNext calculates statutory deductions on daily wage payrolls and generates monthly ECR (Electronic Challan cum Return) for EPFO filing.
Interstate movement of construction materials above ₹50,000 (steel, cement, electrical) requires e-way bills. ERPNext generates e-way bill data from stock transfer entries for inter-state site material movement.
Budget vs actual cost by work package and project — the primary cost control report reviewed at every site review meeting.
Project / ManagementAll retention receivables by project, contractual release date, and days overdue — prevents retention receivables from silently aging into bad debt.
Finance / ManagementPO value, certified work value, billed amount, TDS deducted, and amount paid per subcontractor — complete subcontract financial position.
Purchase / FinanceMaterial issued to each site vs the planned BOM quantity — identifies wastage, pilferage, and reorder requirements per material category.
Site / StoresMilestone billing dates vs expected collection dates vs committed subcontractor payments — the cash flow visibility that prevents project fund shortfalls.
Finance / ManagementAll active projects — contract value, billed to date, cost to date, gross margin — on one screen for management and investor reporting.
Management / BoardEvery material GRN, subcontractor invoice, and labour payroll posts to the project cost centre in real time. Project managers see BOQ vs actual the moment costs are incurred — not weeks later from a spreadsheet update.
Retention receivables are tracked per project with DLP expiry dates and automated alerts. Construction companies commonly leave 2–5% of total project revenue uncollected due to missed retention follow-up. ERPNext eliminates this leakage systematically.
TDS at the correct rate is deducted on every subcontractor payment automatically. No manual calculation errors, no missed deductions. TDS returns and Form 16A are generated directly from ERPNext — saving days of CA preparation time each quarter.
Site-wise warehouses with transfer tracking eliminate the material leakage that plagues construction companies operating multiple concurrent sites. Every bag of cement and every meter of conduit is accounted for against its project.
WPS violations in GCC countries result in suspended labour permits and visa bans — an existential risk for contractors. ERPNext's payroll generates the SIF file for every payroll cycle, ensuring WPS-compliant salary payments without manual file preparation.
Finance, procurement, stores, HR, and project management operating from one ERPNext instance means the Managing Director has a live portfolio view of all projects — without waiting for individual project managers to consolidate and report.
Set up the project cost centre in ERPNext before the first purchase order is raised — not after the first invoices arrive. Retroactively assigning costs to the correct project is time-consuming and error-prone, especially on multi-project companies.
Enforce a PO-first policy in ERPNext — no material can be delivered to site without a system-generated PO. Verbal orders followed by post-facto POs break the three-way match that prevents overpayment and ensures BOQ compliance.
Configure site warehouses and ensure GRNs are raised at the point of site receipt — not at the central store when material is dispatched. Site-level GRN is the only accurate basis for project material cost and theft prevention.
Run the retention outstanding aging report every quarter and action follow-up on all retention past the release date. A quarterly retention collection review typically recovers 1–3% of annual contract revenue that would otherwise be silently written off.
GCC banks require 2–3 processing days after SIF upload for WPS credits to reflect. Process payroll in ERPNext and upload SIF at least 5 working days before the WPS deadline — avoiding the labour permit suspension that follows even a one-day delay.
Make the portfolio profitability report a standing agenda item in weekly director reviews. Projects that slip from budget by 3% without detection typically end at 10% overrun. Weekly visibility closes the detection lag that makes overrun recovery impossible.

India's construction sector — spanning Pune's residential developers, Maharashtra's infrastructure contractors, Mumbai's commercial builders, and Nashik's industrial construction companies — operates under RERA, GST on construction services, TDS on subcontractors, and PF/ESI for labour. In Uttar Pradesh, civil contractors in Noida, Lucknow, Kanpur, and Agra manage large-scale infrastructure and residential projects under RERA UP, with significant BOQ and subcontractor management complexity. In Karnataka, Bengaluru's commercial construction boom — covering IT parks, commercial complexes, and residential high-rises in Whitefield, Sarjapur, and Electronic City — drives demand for ERP with GST at 18%, TDS management, and multi-site visibility. Quantbit Technologies, with offices in Pune (HQ, Bibvewadi), Mumbai (Mahim, 112 Mogul Lane), and Muscat (Oman), is uniquely positioned to implement ERPNext for construction companies operating across India and the GCC — from a single integrated system.

"Before ERPNext, our subcontractor TDS was done manually in spreadsheets — we had missed deductions across three projects that resulted in income tax notices. After implementation, TDS is deducted automatically on every payment. We haven't had a single compliance notice since go-live."
"We had ₹2.3 crore in retention receivables that had passed their DLP release dates and were never followed up. ERPNext's retention aging report identified all of them in the first month. We collected ₹1.8 crore within 90 days of go-live."
