eSUB vs Knowify

Two job management platforms for trade contractors that carry change orders, T&M work and AIA billing through to accounting. eSUB is built for commercial subcontractors, with daily reports, T&M tickets signed in the field and tied to change orders, progress billing with AIA G702 and G703 pay apps, purchase orders, RFIs, submittals and a QuickBooks Online integration. Knowify is project and service management software for commercial and residential trades, sold as a QuickBooks integration, running from estimates and contracts to AIA billing, job costing, time tracking and service dispatch, with an AI Connector on its higher plans. Largely like-for-like on change orders and billing, with Knowify also covering service work and fleet tracking. Vendor pages read Nov 1, 2026; desk research from vendor sites, no winner.

Where the vendor descriptions differ

  • Who each is built for: eSUB says it is built for commercial subcontractors and names electrical, HVAC, concrete, mechanical, masonry, plumbing and structural steel trades. Knowify names commercial and residential trade contractors (electrical, plumbing, HVAC, painting, concrete, excavating and more) and covers both project and service work.
  • Change orders and T&M: eSUB lists T&M tickets with customer signatures captured on a tablet or phone and tied to change orders, and change order quotes as lump sum or by category with line items. Knowify lists change orders, estimating, proposals and contracts as part of project execution.
  • Billing: eSUB says it generates AIA G702 and G703 pay applications from the schedule of values and tracks retainage and which pay apps have been submitted. Knowify lists AIA billing, budgeting, invoicing, payment processing, prevailing wage and job costing.
  • Accounting: Knowify leads with QuickBooks, listing QuickBooks Online, QuickBooks Desktop and Intuit Enterprise Suite among its integrations. eSUB lists a QuickBooks Online integration for its cloud product.
  • Beyond projects: Knowify adds service scheduling and dispatch, inventory, a client portal and optional fleet, equipment and tool tracking. eSUB adds daily reports, field notes, drawings and document control, and promotes Fusion by eSUB, a connected jobsite tool linking field staff with the back office and GCs.
  • AI tags: Knowify is tagged AI features added to an established product because of its AI Connector, which the vendor says lets Claude, ChatGPT and other AI tools answer questions about job margins, billing, labor and collections from Knowify data; its pricing table lists the connector on Advanced and Enterprise, not Core. eSUB stays Not AI-first; the eSUB pages we read do not describe AI.
  • Pricing (checked Nov 1, 2026): Knowify publishes plans: Core $99 or $149 a month with 1 user, Advanced $329 or $399 a month with 10 users, $29 a month per added user, and Enterprise with unlimited users through sales, with a free trial. eSUB publishes no prices; esub.com/pricing returns a not-found page and the calls to action are Talk to Sales and Get A Demo.
  • Not used here: eSUB's 29% productivity, 47% less rework and 25% more change order revenue figures from its own customer survey, and Knowify's claim to the strongest QuickBooks sync in construction. Facts for both tools come from vendor websites (desk research).
