Construction Procurement Software

Onsite construction procurement management software is a digital procurement platform built for contractors, developers, and EPC firms to manage material requests, vendor RFQs, purchase order approvals, and delivery verification in one connected system. It replaces informal WhatsApp-based buying and retrospective purchase orders with a structured workflow where every purchase is requested, compared, approved, and verified before payment is processed. Onsite links every purchase order to project budgets and BOQ line items, giving procurement managers live visibility into committed costs and remaining budget across all active projects.

Onsite prevents informal procurement by making the material request the mandatory starting point for every purchase. Site teams raise requests in the system against BOQ line items and project budgets — the request converts into an RFQ that goes to vendors, the RFQ response converts into a purchase order that goes through approvals, and the purchase order is the document the vendor delivers against. No step in this chain can be skipped. A vendor call made outside this process produces no approved purchase order, which means the vendor invoice has no matching procurement record when it arrives for payment approval.

When an RFQ is sent to multiple vendors, their responses are collected and displayed in a side-by-side comparison in Onsite showing rate per unit, total order value, delivery timeline, payment terms, and vendor performance history from past orders. Procurement managers review the comparison in one screen without cross-referencing emails, WhatsApp messages, or separate spreadsheets. The selected vendor and decision rationale are recorded before the purchase order is issued, creating an auditable record of why a particular vendor was chosen at a particular rate over other available options on that specific procurement decision.

Every purchase order created in Onsite is linked to a project, a cost category, and a BOQ line item. At the moment the PO is created, Onsite displays the remaining budget for that cost category and the committed cost that the new order will add. Procurement managers see the budget impact before approving the order, not after the invoice arrives. If the PO would exceed the remaining budget, the system flags the overrun before the order is released. This budget linkage makes every procurement decision a financially visible one rather than a purchasing decision that finance teams discover at month end.

Three-way matching is the process of comparing a purchase order, a Goods Receipt Note, and a vendor invoice to confirm that quantity, rate, and specifications are consistent across all three documents before payment is approved. Onsite enforces three-way matching automatically — when a vendor invoice is submitted, the system checks it against the approved PO rate and the GRN confirmed quantity. Discrepancies between any two of the three documents flag the invoice for review before it reaches the payment approval queue. This control prevents overbilling from invoices that claim more than was delivered or at rates higher than were agreed.

Site teams record GRNs in the Onsite mobile app at the point of delivery — selecting the relevant PO, entering the received quantity, noting material condition, capturing the supplier challan number, and taking timestamped photos at the gate. The GRN is submitted immediately and Onsite compares received quantities against the PO automatically, flagging any quantity mismatch for procurement review before the GRN is closed. Photos and challan details are stored against the GRN record, providing documentary evidence of the delivery condition that is available during vendor bill approval and project audits.

Yes. Onsite supports multi-project procurement where each project has its own budget, BOQ, vendor assignments, and approval workflows, all managed from one centralized system. Procurement managers view all active RFQs, pending POs, expected deliveries, and outstanding GRNs across every project from a single dashboard without switching between project files or requesting updates from individual site teams. Senior management sees portfolio-level procurement activity — total committed costs, pending approvals, and budget consumption by project — to make resource and cash flow decisions based on live procurement data rather than consolidated reports prepared once a week.

Onsite reduces procurement costs through structured RFQ processes that collect multiple vendor quotations for every purchase, making rate comparison mandatory rather than optional. Procurement teams consistently buying from vendors without checking alternatives pay whatever rate that vendor quotes. Onsite’s vendor comparison view shows the rate difference between available options on every RFQ — a difference that compounds significantly across the dozens of material procurement decisions made on a single project. Additionally, GRN-based verification prevents payment for quantities not delivered, and PO-to-budget linkage prevents unplanned purchases that push project costs above the approved baseline.
