What is epc boq and project cost control software? EPC BOQ and project cost control software organises the Bill of Quantities (BOQ), approved budget, commitments, actual costs and forecasts by project, cost code and work package. BOQ value represents priced scope; budget is the approved spending limit; commitments are contracted amounts; actual cost is recorded expenditure; forecast cost estimates the expected final position.

The operational problem

Why project cost reports arrive after the decision window

Revisions lose their history

BOQ quantities change, but teams circulate renamed spreadsheets. Buyers and commercial teams may work from different versions, creating incorrect package limits.

Commitments stay hidden

Management reviews posted costs while approved purchase orders and work orders sit elsewhere. The apparent budget headroom disappears when invoices arrive.

Variance has no source

A package is over budget, but the report cannot show which order, bill, expense or quantity caused it. Corrective action becomes slow and disputed.

Connected EPC records

Follow value from BOQ line to final cost

Cost control works when each commercial record retains project, WBS, package and cost-code context. A variance can then be traced from summary to purchase order, subcontract bill or site expense.

Core capabilities

Controls your team can evaluate in a demo

BOQ revisions

Maintain controlled BOQ versions and revision context. Prevent teams from treating an obsolete quantity schedule as the current commercial baseline.

Approved budgets

Allocate approved budgets by package, cost code or configured dimension. Give approvers the correct control limit before a commitment is made.

Commitment view

Bring approved purchase and subcontract commitments into cost reviews. Show exposure that has not yet become an invoice or paid cost.

Actual cost

Relate recorded invoices, subcontract bills and expenses to their cost context. Reduce manual reconciliation between accounts and project reports.

Package variance

Compare budget, commitment and actual cost at a useful project level. Direct commercial reviews toward exceptions with material impact.

Forecast context

Combine available cost and progress records to support forecast reviews. Authorised teams retain responsibility for estimate-to-complete assumptions.

Source drill-down

Open the orders, bills and expenses behind a number. Give reviewers evidence without distributing parallel spreadsheets.

A controlled cost review separates priced scope, spending authority, contractual exposure, recorded cost and expected final cost.

Operational takeawayThe view gives authorised teams a shared record for the next decision; it does not replace physical verification or professional judgement.

Buyer questions

EPC BOQ and project cost control software FAQs

What is EPC BOQ and project cost control software?

It connects BOQ scope, approved budgets, purchase and subcontract commitments, actual project costs and forecasts by project and work package.

How are BOQ value and budget different?

BOQ value represents priced contractual scope or an estimate basis. Budget is the internally approved amount available for controlled spending against that scope.

What is the difference between committed and actual cost?

Committed cost is covered by an approved order or contract but may not yet be billed. Actual cost is expenditure recorded through accepted invoices, bills or expenses under the configured accounting process.

Can users trace a variance to its source?

Where connected records are available, authorised users can move from a package variance to relevant purchase orders, subcontract bills, invoices or expenses.

Does the system calculate the final forecast without judgement?

No. Available records can support forecast reviews, but authorised commercial and project professionals remain responsible for assumptions, estimate-to-complete and margin judgement.

Can our existing cost codes and approval limits be configured?

Yes. Cost dimensions, fields, roles, validations and approval paths can be mapped during implementation, subject to the agreed design.
