Construction ERP Software& App for EPC Companies

Onsite uses the BOQ as the connecting layer across all three phases. In Engineering, the BOQ is loaded with quantities, unit rates, and budget allocations. In Procurement, every material request and purchase order is raised against a specific BOQ item — so budget exposure is visible before any commitment is made. In Construction, site engineers update progress against the same BOQ items from mobile. This means cost position, billing readiness, and budget vs actual all update in real time as work progresses — without separate reconciliation between departments.

Yes. Onsite is designed for multi-site EPC operations. Head office gets a consolidated view of all active sites — labour counts verified by GPS attendance, daily progress reports submitted by site engineers from mobile, and cost positions updated as work happens. Each site has its own BOQ, budget, and team structure, but leadership can compare performance across sites, track cost exposure at a portfolio level, and receive alerts when any site deviates from plan — all from a single dashboard.

Every purchase order in Onsite is raised against a BOQ line item and a confirmed budget position. Before a PO is submitted for approval, the system checks whether the committed amount plus the new PO would exceed the allocated BOQ budget. If it does, the PO is flagged and requires a higher approval level before it can proceed. Multi-level approval chains — from Site Engineer to Project Manager to Director — can each hold a gate. This means overspend is caught before it becomes a committed liability, not after.

Onsite generates subcontractor running bills directly from verified installed quantities, not from time or schedule. Before a bill reaches accounts, site engineers confirm the progress milestone on mobile and the system cross-checks against the digital work order. Retention percentages are applied automatically on every bill — no manual ledger maintenance. Final retention releases are tracked and triggered when verified completion conditions are met. This eliminates disputes at handover and ensures EPC companies never pay ahead of confirmed work.

Onsite integrates natively with Tally and Zoho Books, eliminating double entry between site operations and accounts. Vendor bills approved in Onsite sync to your accounting system automatically. Labour payroll calculated from verified GPS attendance exports directly for salary processing. EPC companies using Onsite typically stop maintaining parallel Excel sheets within the first month of go-live because all financial data flows from site activity directly into their accounting system without re-keying.

Most EPC teams are operational within 3 to 7 days. Onsite provides a dedicated onboarding manager at no extra cost who sets up your project structure, BOQ, rate library, vendor master, and user access before go-live. Site engineers typically need less than an hour of training to start submitting DPRs and attendance from mobile. Unlike complex ERP implementations that take months, Onsite is designed to match how construction teams actually work — so adoption happens on site, not in a training room.

Yes. Onsite is actively used by EPC and construction teams across India and the Gulf — including projects in the UAE, Qatar, Oman, and Saudi Arabia. The platform supports multi-currency projects, mixed Indian and expatriate workforces, and cross-border procurement workflows. GPS attendance works across all geographies. EPC companies managing projects in both India and the Middle East use Onsite to maintain consistent reporting, cost tracking, and procurement controls regardless of project location.

Generic ERPs are built for enterprise administration — finance, HR, inventory — adapted for construction as one of many verticals. Onsite is built exclusively for construction execution. Every module — BOQ management, procurement, labour attendance, subcontractor billing, progress tracking, DPR — is designed around how EPC projects actually run on site. This means site engineers adopt it without training overhead, field data flows directly into cost views without consolidation, and budget overruns are caught at the procurement stage rather than discovered at month-end close.
