Frequently asked questions
What does eSUB actually do?
eSUB is cloud construction management software for commercial subcontractors. It manages project documents and field communications in one place: submittals, RFIs, change orders, daily reports, field notes and purchase orders. Field teams use a mobile app, and project information and documents are stored with unlimited cloud storage.
Who is eSUB designed for?
Commercial specialty trade subcontractors. The vendor states the product exists specifically to meet the needs of commercial construction subcontractors, and names concrete, drywall, glazing, steel, electrical, HVAC, plumbing and mechanical contractors among its users.
How much does eSUB cost?
Pricing is not published on the vendor site. The site directs buyers to book a demo, so commercial terms are provided through the sales process. Budget for a quoted annual subscription rather than a self-serve list price.
Does eSUB integrate with other software?
Yes. The vendor states eSUB now offers a seamless integration with QuickBooks Online accounting software, and markets 'connected integrations that work with your existing software'. The specific integration catalogue beyond QuickBooks Online is not detailed on the product page.
Does eSUB publish security or compliance certifications?
No security, trust or compliance page was available in the sources reviewed, so certifications such as SOC 2, ISO 27001, HIPAA or FedRAMP could not be verified. Buyers with strict compliance requirements should request current documentation directly from the vendor.
