eSUB vs GCPay

Two pay-app tools on opposite sides of the subcontractor billing exchange (our reading). eSUB is project management software for commercial trade subcontractors, whose Progress Billing module builds the schedule of values and generates the AIA G702/G703 pay applications a sub sends, while GCPay is bought by general contractors to collect and approve subcontractor pay apps, lien waivers and compliance documents and release payment. Neither vendor page describes AI features. Desk research from vendor sites read Nov 2, 2026; no winner.

The pages we read do not describe AI features; productivity and revenue figures from the vendor's customer survey are not used.Cloud software that automates pay applications, lien waivers and compliance documents between general contractors and subcontractors. It covers pay app workflows and automation, lien waiver creation and exchange, compliance document collection, ERP and accounting integration, electronic payments with the lien waiver held in escrow so a signed copy can be viewed before payment is released, reporting and dashboards, custom reports, and official AIA documents. Its change order page says approved change orders sync into the schedule of values (SOV) and pay apps and entries are checked against SOV and contract values. The ERP page names Sage 300 Construction and Real Estate, Sage 100 Contractor, Sage Intacct Construction, Vista by Viewpoint, CMiC, Acumatica and an Autodesk Forma Build integration. The pages read do not describe AI features, so it is tagged Not AI-first. Customer counts, volume counters, support-time figures, return claims, the cost-benefit calculator and customer quotes are vendor material and are not used.

Where the vendor descriptions differ

  • Who buys it (vendor pages): eSUB names commercial subcontractors such as electrical, HVAC, concrete, mechanical, masonry, plumbing and structural steel trades. GCPay names general contractors' CFOs, controllers, project accountants and PMs, with subcontractors submitting through it.
  • Billing workflow: eSUB's Progress Billing page describes a schedule of values tied to contract value that updates as change orders are approved, line-item percent-complete, work-in-place, stored-materials and retainage calculations, G702/G703 pay apps generated from the SOV (or built manually), and a dashboard of billed, approved, outstanding and disputed amounts. GCPay lists pay app workflows and automation, official AIA documents, and checks of entries against SOV and contract values.
  • Change orders: eSUB lists change order tracking with lump-sum or category-based quotes and line items, plus T&M tickets with customer signatures and references to related change orders. GCPay's change order page says approved change orders sync into the SOV and pay apps.
  • Waivers, compliance and payment: GCPay lists lien waiver creation and exchange, compliance document collection, and electronic payments with the lien waiver held in escrow so a signed copy can be viewed before payment is released. The eSUB pages we read cover building and tracking the sub's own billing, not GC-side waiver collection or payment release.
  • Connections: eSUB names a QuickBooks Online integration. GCPay's ERP page names Sage 300 Construction and Real Estate, Sage 100 Contractor, Sage Intacct Construction, Vista by Viewpoint, CMiC, Acumatica and an Autodesk Forma Build integration. Neither page we read describes a direct eSUB to GCPay connection.
  • Where the AI sits: neither vendor page describes AI features; the automation both describe is calculation, checking and approval workflow (our reading). Both stay tagged Not AI-first.
  • Pricing (read Nov 2, 2026): neither publishes prices. eSUB routes to Talk to Sales and Get a Demo (esub.com/pricing returns not found). GCPay says pricing is custom and its pricing page describes volume-based and usage-based options for general contractors; book a demo.
  • Using both: a sub that bills from eSUB may be asked to submit through a GC's GCPay portal, so ask both vendors how a pay app built in eSUB gets there.
  • Not used here: eSUB's customer-survey productivity and revenue figures, GCPay's customer counts, volume counters, return claims and calculator, and both vendors' customer quotes. Facts for both tools come from vendor websites (desk research).

Paraphrased from the sources listed above. Vendor claims are reported as claims.
