Construction Payroll Software Built for Contractors

Lumber automatically generates certified payroll reports in WH-347 format and state-specific variations required for federally and state-funded construction projects. The system pulls approved timesheets, applies the correct prevailing wage rates and fringe benefit calculations by project and trade classification, and produces audit-ready reports. Reports can be exported in PDF, XML, or CSV and submitted directly to the relevant agency. LumberAI also scans certified payroll data in real time to flag missing entries, anomalies, or compliance violations before submission.

Yes. Lumber is built to handle prevailing wage compliance under the Davis-Bacon Act and state equivalents. You configure project-specific prevailing wage rates — base rate plus fringe benefits — by trade classification and county, and Lumber applies them automatically to every payroll run. The system validates payroll against the configured rates before certified reports are generated, flagging any discrepancies. For contractors working on infrastructure projects funded by the IIJA or state programs, Lumber handles the full compliance workflow without manual spreadsheet calculations

Yes. Lumber supports union payroll for multiple trades simultaneously. You configure pay scales, shift differentials, fringe benefit contributions, dues, and apprenticeship fund remittances per collective bargaining agreement. Lumber calculates deductions and contributions automatically for each payroll run and generates the reports required by union halls and government agencies. The system handles home and away union hall logic and supports contractors working under multiple CBAs across different trades on the same project.

Standard payroll handles a fixed set of employees at consistent rates in one or two locations. Construction payroll is significantly more complex. Workers move between projects with different wage rates. Some projects require certified payroll reporting with weekly government submissions. Union contractors must track and remit fringe benefits per trade agreement. Crews frequently work across multiple states, triggering different tax rules in each. Labor costs must be coded to specific projects and cost centers for job costing. Generic payroll software requires manual workarounds for all of this. Construction payroll software like Lumber automates these requirements natively, reducing payroll processing time by up to 95% and eliminating the compliance risk of manual calculations.

Lumber integrates with the most widely used construction accounting and ERP platforms, including QuickBooks, Sage 300 Construction and Real Estate, Sage Intacct, Sage 100 Contractor, Acumatica, NetSuite, and Premier Construction Software. Integrations eliminate double data entry between payroll and accounting, ensure labor costs flow directly to job cost reports, and keep your general ledger in sync with every payroll run.

Yes. Lumber is used by specialty subcontractors across trades including electrical, plumbing, HVAC, drywall, masonry, and concrete. Subcontractors working on public works projects benefit most from Lumber's automated certified payroll and prevailing wage features, which eliminate the hours of manual reporting required on government jobs. Lumber scales from small crews of 5 to large subs with hundreds of workers across multiple active projects, without adding administrative complexity as you grow.
