Subcontractor Billing at Construction Speed.

Process progress billing, multi-site invoicing, and high-volume subcontractor payments from spreadsheets and documents — with QuickBooks integration built in.

Why Construction Billing Never Keeps Up

Construction billing is project-based, progress-dependent, and multi-site. Standard invoicing tools were not designed for this.

Multi-Site Complexity

Different sites, different project managers, different spreadsheet formats. Consolidating billing data from multiple locations is a monthly headache.

Progress Billing Calculations

Construction invoices are based on percentage completion, change orders, and retention. Calculating these manually for hundreds of line items is slow and error-prone.

Subcontractor Volume

A single project can have 20+ subcontractors, each with their own billing schedule and format. Processing them all is a full-time job.

Pay Application Delays

Slow invoice processing delays pay applications, which delays payments, which strains subcontractor relationships — a cascading problem.

How Construction Billing Automation Works

From site data to QuickBooks invoices — with construction-specific intelligence built in.

1

Collect Site Billing Data

Upload spreadsheets from project managers, import from project management tools, or process subcontractor invoices directly.

2

Calculate Progress and Retention

The system calculates billable amounts based on completion percentage, retention hold, and previous billings — matching your contract terms.

3

Validate and Preview

Review calculated invoices by site, subcontractor, and project. Flag exceptions before invoice creation.

4

Create Invoices in QuickBooks

Batch-create all invoices in QuickBooks with project codes, retention amounts, and change order references.

5

Generate Pay Applications

Export pay application summaries for general contractors and project owners. All data matches the created invoices exactly.

Purpose-Built for Construction
