Job costing and progress billing for contractors

How project cost, certified work, retention, and receivables stay connected—so margin stays visible while work is still underway.

Contractor control benefits

Progress with retention

Site and HQ same books

IVA inside PerfectoERP

Ask IVA about construction on your live screens—what a capability means, why a document is blocked, or which report explains a variance. Guidance stays inside your job functions and permissions.

Top capabilities in depth

Job costing & billing capability map

Budget versus actual and progress bills that finance can post with confidence.

Top feature

Job cost visibility

Materials, labor, and subcontractor spend against the project structure you planned.

Earned value signals

Percent complete and budget tiles surface overruns before month-end surprises.

Progress billing loop

Claims follow site evidence into receivables on the same ledger.

One project truth

Site, cost, and billing stop living in three files that never match.

Why contractors need connected control

Job costing works when commitments, site costs, and client certificates live in one place. When they live in three tools, controllers discover margin leaks only after the month closes—and finance spends nights rebuilding what the site already knew. PerfectoERP keeps budget, actual cost, and billable progress on the same project so controllers see margin by site while finance posts from the same documents.

A clear sequence starts with structure. Open the project with phases, cost codes, or BoQ-aligned lines that match how you measure work. Capture purchase commitments and material issues against that structure so cost arrives with context—not as a generic expense waiting for someone to allocate it later.

If finance re-keys progress bills from Excel, you are paying for ERP twice.

Progress / AR

Certified quantities or milestones come next. Whether you bill by measurement, stage, or milestone, the certificate should sit on the same project that holds the budget. Generate progress bills with prior amounts and retention so receivables reflect what the client has already paid and what is still held.

Retention and variation orders are where many contractor systems break. In PerfectoERP they are first-class billing events—not end-of-month spreadsheet adjustments. When a variation is approved, budget and billable scope expand in one workflow your quantity surveyor and finance team both see.

Revenue recognition follows your policy, but the operational foundation stays the same: certified work, retention, and cost must be traceable to the project. That audit trail matters for owners, auditors, and lenders who ask how margin moved during the period—not only at final account.

ScenarioCivil contracting firm

Progress bills that match what was certified

Challenge

Certificates lived in files; AR re-keyed amounts; retention and prior bills drifted from project cost.

Approach

Job cost and progress billing in PerfectoERP kept measurements, retention, and client invoices on the project with a trail into revenue.

Outcome

Billing meetings started from certified work—not from reconstructing Excel packs.

Margin protection in practice

Construction features that protect margin

Project codes everywhere

POs, issues, and certificates carry the same codes finance costs against.

Progress billing with retention

Client bills stay tied to prior amounts and project budget.

Materials & subcontractors on site

Receiving and certificates feed job cost—not email attachments.

This path creates value when project accountants close progress bills inside the ERP instead of reconstructing packs in Excel. IVA explains posting screens and approval steps on live documents so teams understand the capability in depth—not only in a slide deck.

Multi-site portfolios need the same discipline at scale. Filter and report by project, cost center, or region without rebuilding files. Contractors in the Americas, Europe, MENA, and elsewhere share that control need even when currency and language differ.

PerfectoERP supports bilingual operation so site and head office work in the language each team prefers—on one company. Pair job costing with purchasing and inventory so commitments and issues feed the same margin view your billing team uses for the next certificate.
