How we work

General contractors and specialty subcontractors run their business one project at a time, and generic accounting software cannot say whether job 4471 is profitable until the job has closed. Construction ERP has to track cost against budget in real time by cost code, across labor, materials, equipment, and subcontracts. Otherwise the project manager learns about a cost overrun in the same month the client does.

We build ERP systems around job costing as the core structure: budgets set by cost code at the start of a project, actual costs (labor, materials, subcontracts, equipment) posted against those codes as they happen, and progress billing that follows the AIA G702/G703 format clients and lenders expect. Change orders, retainage, and lien waiver tracking get built in from the start, since a system that treats these as an afterthought creates exactly the reconciliation headaches contractors already deal with in spreadsheets.

The pattern extends to subcontractor management, tracking insurance certificates, compliance documents, and payment applications, and to certified payroll reporting for prevailing wage jobs, where a missed or incorrect report can hold up payment on an entire public works contract.

The problem

How construction projects differ

Job costing accuracy in near real time
A project manager needs cost-to-date and cost-to-complete visibility by cost code without waiting for month-end close, or budget overruns surface only after the damage is already done.
AIA-style progress billing
Owners and lenders expect progress billing in a G702/G703-style format showing percent complete, retainage, and prior billings, and generating this manually every billing cycle invites errors.
Subcontractor compliance tracking
Insurance certificates, lien waivers, and licensing documents need to stay current for every active subcontractor, since paying a subcontractor with an expired certificate creates real liability exposure.
Certified payroll for prevailing wage jobs
Public works contracts require certified payroll reports matching prevailing wage rates by classification, and an incorrect submission can delay payment on the entire contract.
Change order and retainage tracking
Change orders shift both budget and billing simultaneously, and retainage held across multiple pay applications needs to reconcile precisely at project closeout.

Scope

Features we often include

Job costing by cost code
Budgets and actuals tracked by cost code across labor, material, equipment, and subcontract categories, giving real-time cost-to-complete visibility per project.
AIA-format progress billing
Pay applications generated in a G702/G703-style format with retainage and prior billing carried forward automatically from project cost data.
Subcontractor management
Insurance certificate expiration tracking, lien waiver collection, and payment application review tied to each subcontract.
Certified payroll reporting
Payroll reports formatted to prevailing wage requirements by trade classification, generated directly from time and job cost data.
Change order management
Change orders that update project budget and client billing together, with an approval workflow and audit trail for each one.
Equipment and asset tracking
Equipment usage logged against jobs for internal cost allocation, with maintenance scheduling tied to hours or mileage.
RFI and submittal tracking
Requests for information and submittal logs tied to project documents, with status and response deadlines visible to the project team.

Approach

How these projects run

We begin by mapping how the company currently tracks job cost, usually a mix of spreadsheets and whatever the accounting system happens to allow, and identify exactly which cost codes, billing formats, and compliance reports the new system has to reproduce correctly from day one. Progress billing and certified payroll formats get validated against real prior pay applications before we consider them done.

Because most contractors cannot pause active projects during a system transition, we build and pilot the job costing and billing modules on one active project before migrating the full project list, and we keep historical job cost data intact for comparison. Your team retains ownership of the ERP's codebase and infrastructure from the first commit.

FAQ

Frequently asked questions

How does a construction ERP track job costing in real time?

Costs post against a project's cost codes as labor hours, material purchases, and subcontract invoices are entered, rather than waiting for a month-end accounting close, so project managers can see cost-to-complete for each cost code while a job is still active. This is the core difference between construction ERP and generic accounting software.

Can the ERP generate AIA-style pay applications automatically?

Yes, we build progress billing to follow a G702/G703-style format, pulling percent complete, retainage, and prior billing amounts directly from the project's cost data instead of requiring a separate manual spreadsheet each billing cycle. This reduces the errors that come from re-entering the same numbers in two places.

What is certified payroll reporting and does our ERP need to generate it?

Certified payroll reports document that workers on a public works project were paid at least the prevailing wage rate for their trade classification, and they are required on most government-funded construction contracts. If your firm bids on public works, we build this reporting directly from time and job cost data so it does not become a separate manual process.

How long does it take to build a custom construction ERP?

A focused system covering job costing, progress billing, and subcontractor management typically takes a few months, with certified payroll reporting and integrations to tools like Procore or Bluebeam adding time depending on scope. We scope the specific modules you need during discovery rather than building every feature by default.

Can the ERP integrate with Procore or our existing accounting system instead of replacing everything?

Yes, many contractors keep Procore for field management and project communication and use the ERP for job costing, billing, and payroll, syncing data between the two systems. We scope the integration boundary during discovery so cost data has one clear system of record.
