Frequently asked questions
Knowify scores F on the API Report Card. No openly published REST API. Knowify markets public-facing APIs, but the practical surface is a Zapier app with API key auth plus QuickBooks, CompanyCam, and Square connectors. Rate limits, webhooks, and OAuth flows are not documented publicly.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly.
Knowify is a cloud-based construction management and job-costing platform purpose-built for trade contractors and residential remodelers.
Construction, specifically small-to-midmarket trade and specialty contractors (electrical, plumbing, HVAC, painting, concrete, excavation, drywall, mechanical, and general remodelers). Estimators build bids and convert them into contracts and budgets; PMs manage change orders, RFIs, daily logs, and documents; field crews clock in/out via mobile (with GPS) and log materials; office staff run AIA-style progress invoices, schedule of values, T&M invoices, subcontractor lien waivers, and POs; bookkeepers sync invoices, bills, payments, vendors, customers, employees, and POs bidirectionally to QuickBooks Online, QuickBooks Desktop, or Intuit Enterprise Suite.
Medium within its niche.
Knowify holds the operational and financial backbone of a trade contractor: every bid and estimate, signed contracts and change orders, schedule of values, AIA G702/G703-style progress billings, T&M invoices, customer and vendor masters, subcontractor agreements and lien waivers, POs and bills, job-cost ledgers (labor, materials, subs, equipment), time cards with GPS, daily logs and photos (often via CompanyCam), service tickets, payment records via QuickBooks Payments, and a bidirectional sync of the same data into QuickBooks Online / Desktop / Intuit Enterprise Suite.
Mature SMB SaaS. Launched in 2012, Knowify is ~13 years old with a stable web app and an active product roadmap (Intuit Enterprise Suite integration shipped January 2025, ongoing investment in service-work and dispatch).
No openly published REST endpoint reference, rate limits, or webhook docs, developers are pushed to Zapier rather than direct API integration. QuickBooks integration (the primary 'API' surface most customers touch) repeatedly breaks on edge cases like multi-entity setups and imperfect data entry. Full sourced list under Sources below.
Common alternatives include Procore, Buildertrend, CoConstruct, Contractor Foreman, JobTread, Workyard. Graded alternatives appear under "More from the report card" below.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial Knowify API and MCP server so AI agents and internal tools can read and write Knowify data. See the Knowify integration docs at supergood.ai/docs/knowify-api.
