Knowify is construction project and service management software built around a deep QuickBooks integration, positioned for trade contractors and specialty subs. It covers estimating, proposals and contracts, job costing, invoicing (including AIA billing), scheduling, time tracking, and subcontractor management, keeping costs synced with QuickBooks Online and Desktop. For a QuickBooks-first shop that wants its field and office data flowing into the books, Knowify is a well-established option. See knowify.com for its current feature set, integrations, and QuickBooks version support.
Corten Technologies is construction management software for small and mid-size general contractors and subcontractors (1-20 people, with an Enterprise tier for 21+), built around an AI that removes manual data entry. Corten's AI reads the documents you already have, subcontractor proposals and bids, vendor quotes, receipts, timesheets, invoices, and drawings, and auto-loads each into the right place: sub quotes flow into trade worksheets and roll up to the bid sheet, and the proposal drafts itself from the winning numbers with scope written from the subs' own quotes. Everything is queued for human review, never blindly retyped. From there it's one connected workflow, enter once and it flows from bid to proposal to budget to schedule to invoice, with estimates converting to jobs, jobs generating invoices, and approved change orders rolling into the budget automatically using canonical bid-total math, markups, and profit. In the field, crews handle tasks, punch lists with photo uploads, daily logs, RFIs, and submittals from any phone or tablet, with SMS reminders. Data is isolated per company at the database level with role-based access, weekly 2FA, and HTTPS.
Corten's pricing is published and flat: Solo is $99/mo for 1 user, Crew is $229/mo for 2-8 users, General Contractor is $449/mo for 9-20 users, and Enterprise is custom for 21+. AI is included in every plan with no add-on, and there is a 14-day free trial with full AI (the current beta adds 2 months free). Knowify publishes tiered plans and a free trial on its site; for its current rates, per-user terms, and what each tier includes, see knowify.com.
