What eSUB Construction Software does

eSUB Construction Software, founded in 2008 and headquartered in San Diego, California, is a privately held SaaS provider of cloud-based construction project management software built exclusively for commercial subcontractors. The company's flagship product, eSUB Cloud, is a unified platform comprising 16 modules — including Daily Reports, Change Orders, RFIs, Submittals, Field Notes, Document Control, Drawings, Time & Materials, Job Costing, Progress Billing, Purchase Orders, and Reporting & Analytics — designed around the documentation, field-to-office communication, and financial tracking workflows of specialty trade contractors. In 2023, the company launched Fusion by eSUB, a connected jobsite sub-brand that links external field personnel to back-office systems via web and mobile interfaces.

The company serves hundreds of commercial subcontractors across seven specialty trades — electrical, HVAC, plumbing, mechanical, concrete, masonry, and structural steel — with primary users being executives, project managers, foremen, and office staff. eSUB monetizes through annual SaaS subscriptions priced on a quote-based, non-publicly-disclosed basis, distributed via enterprise field sales and inside sales motions with demo-led conversion. The platform integrates with QuickBooks Online (core), Sage, Xero, and STACK Construction Technologies to synchronize project and accounting data. Customer-reported outcomes from a 2023 survey include 29% productivity gains, 47% rework reduction, and 25% revenue increase on change orders. The product suite is sold almost exclusively in the United States.

eSUB has raised approximately $22 million across multiple funding rounds (2015-2023) from investors including Catalyst Investors, Revolution Ventures, Revolution, and Autodesk, and is led by CEO Erich Litch with founder Wendy Rogers on the board. The company operates as eSUB, Inc. with 51-100 employees and no disclosed international footprint.
