eSUB review
Bottom line
eSUB is a construction management platform built only for commercial trade subcontractors, covering field communications, change orders, and AIA pay applications. Its clearest strength is progress billing that generates G702 and G703 forms directly from a schedule of values, with approved change orders flowing in automatically. Buyers should weigh pricing, which starts at $49 per month with no free plan and requires a sales conversation for full details. It suits small and mid-size commercial subcontractors that bill general contractors on AIA forms and want field and office work in one system.
What is eSUB?
eSUB is construction management software built for commercial trade subcontractors, including electrical, HVAC, concrete, drywall, glazing, steel, and mechanical firms. It targets the paperwork and communication gaps that slow subcontractors down, from field crews waiting on drawings and RFI answers to billing errors that delay payment from general contractors. The company was established in 2008 and reports more than 16,000 users.
Day to day, field staff use the eSUB Cloud mobile app to create field notes, keep daily reports, process submittals, submit RFIs, and send change orders from the jobsite. The app works offline and shows real-time updates, so crews can access project documents on their devices. Office and project management teams handle the back end: they build a schedule of values, track percent complete and retainage by line item, and generate AIA G702 and G703 pay applications from that schedule. Purchase orders track material costs by labor activity, and time tracking and job costing show where each project stands.
eSUB serves small and mid-size businesses. Its users include executives, project managers, foremen, and office staff. Pricing starts at $49 per month, and a free trial is available, but there is no free plan. Full pricing is provided on request through the sales team.
eSUB stands apart from general-purpose tools because it is built only for subcontractors, not general contractors. Its billing workflow follows the subcontractor relationship with GCs, with approved change orders added to the schedule of values automatically. It also connects to accounting and project systems such as QuickBooks Online, Sage 100, Sage 300, Viewpoint, and Jonas Construction Software. For a subcontractor that bills several GCs at once, that focus on the sub's side of the job is the main reason to choose it.
