Knowify

Knowify is a construction management platform built specifically for trade contractors and subcontractors. Founded in 2012, it covers the full lifecycle of a contracting business, from estimating and proposals through to job costing, scheduling, and invoicing. Its deep QuickBooks integration is the standout feature, with real-time two-way syncing that genuinely reduces double entry. For contractors already running QuickBooks, it slots in naturally.

The integration picture beyond QuickBooks is more limited. Knowify has an API, but the documentation is thin and the developer portal feels underdeveloped compared to bigger players. Most third-party connections run through Zapier, which works well for simple automations but adds cost and complexity for anything sophisticated. If you need tight custom integrations with other systems, budget extra time and expect to lean heavily on Zapier.

The company is small but stable, with around 50 employees and consistent growth since 2012. It is still founder-led, which is a good sign for product direction. Customer support gets consistently strong reviews, and the desktop product is well-regarded. The mobile app, however, has significant issues that are worth knowing about before you commit.

Knowify was founded in 2012 in New York City by Marc Visent and Daniel de Roulet Jr. The company set out to bring modern business management tools to trade contractors, a segment that larger construction software vendors were largely ignoring at the time. Both co-founders are still running the company, with Visent as CEO and de Roulet as CTO.

The company has raised approximately $8-11 million across multiple funding rounds, with investors including AXA Venture Partners, Point Nine, and ff Venture Capital. As of late 2025, Knowify has around 50 employees across North America and Europe, and reported $6 million in annual revenue in 2024. It is a Series A company, still relatively small but showing steady growth. The founder-led structure and consistent product development suggest the company is building for the long term rather than chasing a quick exit.

Knowify is an all-in-one business management platform designed for commercial subcontractors and residential remodelers. It handles estimating, proposals, contracts, scheduling, time tracking, job costing, and invoicing in a single system. The platform supports construction-specific workflows including AIA billing, change orders, certified payroll, and prevailing wage tracking.

The target market is small to mid-sized trade contractors, typically teams of 2 to 200 people. Knowify handles both long-term contract jobs and service work in one system, so contractors do not need separate tools for project work and maintenance calls. The scheduling tools include Gantt charts and drag-and-drop resource allocation, while the financial side covers everything from cost-plus contracts to real-time work-in-progress reporting.

Knowify was built from the ground up to complement QuickBooks, and that integration remains its strongest selling point. The platform also includes a CRM for managing leads and a client portal for sharing project updates.

Knowify uses tiered monthly pricing with annual discounts. The Core plan starts at $99 per month (billed annually) or $149 month-to-month, covering one user with essential features like estimating, scheduling, time tracking, and AIA billing. The Advanced plan at $249 per month (annual) adds project budgets, job costing, real-time WIP reporting, advanced reporting, and Zapier integration. Enterprise pricing is custom and includes unlimited users, equipment management, RFIs and submittals, and QuickBooks Desktop integration.

There are also add-ons: Service Pro at $99 per month (annual) for dispatching and service work, and Prevailing Wage at $79 per month (annual) for Davis-Bacon compliance. Additional users cost extra on the Core and Advanced tiers. A free trial is available without requiring a credit card.

Knowify has an API with key-based authentication and an OpenAPI specification available. There is a developer portal at knowify.com/docs with API reference documentation, though it is not particularly comprehensive compared to more established platforms. The API appears to cover core entities like jobs, clients, invoices, and bills, but the depth and breadth of available endpoints is not well documented publicly.

For most users, the practical integration path is through Zapier, which offers around 15 triggers (covering events like new invoices, clients, contract jobs, and service jobs) but only one action (creating a contract job). This means you can get data out of Knowify easily enough through automations, but pushing data back in is limited. The QuickBooks integration is native and well-developed, handling real-time two-way syncing of financial data. Other native integrations include CompanyCam, QuickBooks Time, and several payroll providers.

Rate limits are not publicly documented, which makes it hard to assess suitability for high-volume custom integrations. Overall, the API exists and works, but it is clearly secondary to the native QuickBooks integration and Zapier as integration strategies.

Knowify allows data export from several screens including Manage Clients, Manage Vendors, Manage Catalog, and Review Time, all in XLS format. You can include historical data (closed bills and invoices) by toggling the Show History option before exporting. The QuickBooks integration also means your financial data lives in both systems simultaneously, which provides a natural backup of accounting data.

However, there is no bulk export of all data in a single operation, and more complex data like project structures, scheduling information, and document attachments would require API access to extract. If you needed to migrate away from Knowify completely, you would get your financial data out through QuickBooks and your client and vendor lists through the XLS exports, but project history and job costing details would take more work to extract.

The developer experience is a mixed bag. On the positive side, Knowify does have a developer portal with API reference documentation and OpenAPI specs, which puts it ahead of some construction software competitors. The Zapier integration is straightforward to set up and covers the most common automation scenarios.

On the downside, the API documentation lacks depth. Public information about rate limits, error handling patterns, and pagination is scarce. There does not appear to be a dedicated sandbox environment for testing, though the free trial could serve that purpose for initial exploration. Community examples and third-party guides are limited, so developers will be largely on their own when building custom integrations. The QuickBooks integration is well-documented through Knowify's help centre, but that is about business configuration rather than developer implementation.

Lock-in risk is moderate. Your financial data stays accessible through QuickBooks, which is a significant safety net since accounting data is often the most critical thing to preserve. Client and vendor lists can be exported as spreadsheets. However, project structures, job costing history, scheduling data, and documents would be harder to extract in bulk. The API could help with migration but is not well-documented enough to make that process straightforward. If you are deeply invested in Knowify's project management and job costing features, switching to another platform would involve some manual data reconstruction. The QuickBooks sync does mean you are not losing your financial trail, which is the most important thing.

Webhook support is mentioned in the developer documentation, but details on available events and configuration are sparse. Most event-driven integrations rely on Zapier polling rather than direct webhooks.

Knowify is a solid choice for small to mid-sized trade contractors who already use QuickBooks and want a construction-specific layer on top. The QuickBooks integration is its strongest asset, and the platform covers the full business lifecycle from estimating through to invoicing in a way that makes sense for subcontractors and remodelers.

Where it falls short is beyond the QuickBooks ecosystem. If you need tight integrations with CRMs, ERPs, or other business systems, you will be working through Zapier or a thin API, and that adds friction and cost. The mobile app needs significant improvement for field teams who rely on it daily.

This is a good fit for contractors who want to professionalise their business operations and are happy working within the QuickBooks ecosystem. It is not a great fit for businesses that need heavy custom integrations, have strict security compliance requirements, or depend heavily on mobile field tools. If QuickBooks is your accounting backbone and you want construction-specific project management built around it, Knowify delivers on that promise.

Knowify does not publicly advertise any security certifications such as SOC 2 or ISO 27001. Their privacy policy (updated December 2024) states that data is transferred to and processed in the United States. They commit to disclosing any security breaches in the most expedient time possible. No known data breaches or security incidents have been publicly reported. For a company of this size serving small trade contractors, the absence of formal certifications is not unusual, but larger or compliance-sensitive businesses should enquire directly about their security practices.
