One ledger for a contractor running six disconnected systems
A multi-site contractor ran procurement, payroll, project costing and accounts in six tools that never agreed. We deployed and configured Oplyra ERP as the single ledger, migrated and reconciled the data, and cut the month-end close.

- Fewer cost overruns at final account
Overview
The challenge and our approach
01The challenge
Estimates lived in spreadsheets, purchase orders in a trading system, site progress in WhatsApp groups and invoices in an accounting package that knew nothing about any of them. Finance spent the first two weeks of every month stitching the pieces together.
Variation orders were the real leak. A change agreed on site took weeks to reach a priced, approved document, so work was often done — and paid for — before anyone knew what it would cost.
02Our approach
We built one ledger that every department writes to. A project starts as an estimate, becomes a budget when the tender is won, and every purchase order, site report, variation and invoice posts against that budget line as it happens.
Variations got their own flow: a site engineer raises one from a phone, the estimator prices it against the original rates, and approval routes to whoever holds that budget. Month-end stopped being a reconciliation exercise because the numbers were already joined.

The build
What we built
Modules rolled out department by department, each replacing one legacy system.
Estimation & tendering
Rate libraries and bills of quantities that turn straight into a project budget when the job is won.
Variation orders
Raised on site, priced against contract rates and routed to the budget owner for approval.
Procurement
Requisitions, supplier quotes and purchase orders committed against the right budget line.
Project ledger
Committed, actual and forecast cost per line — the single number finance and site both read.
Forecasting
Cost-to-complete predictions trained on past projects, flagging overruns while they can still be fixed.
Approvals & audit
Role-based limits and a full trail of who approved what, against which revision.
Results
Month-end stopped being a project of its own
Measured across the first twelve months with every department live.
40%
Faster month close
Costs post against the budget as they happen, so there is little left to reconcile.
6 → 1
Systems
Estimating, trading, site, HR, approvals and accounting run on one ledger.
2 days
Variation turnaround
Changes are priced and approved before the work is done, not after.
18%
Fewer overruns
Forecasts flag a line drifting over budget weeks before the final account.

Senior people, every call, for eighteen months. That is the whole difference and it shows in the product — our finance team closes the month in days, not weeks.
