“Can a contractor-focused vertical SaaS become the financial operating system for small trade businesses by embedding payments, lending, and client financing into the estimating-to-invoice workflow?”
Joist began as a mobile estimating and invoicing app for contractors, positioned as a vertical SaaS tool for the construction and home improvement trades. Over time it expanded into embedded finance by layering payments (Joist Payments, powered by Stripe), business lending (Joist Lending, powered by Fundbox), and consumer financing for end-clients (Acorn Finance marketplace, Klarna BNPL). The company is part of the EverCommerce / EverPro platform, positioning embedded finance not as a standalone product but as a stickiness driver within its contractor-workflow SaaS.
Joist processes payments through Stripe Connect.
Joist integrates with QuickBooks Online.
The Embedded Finance Index 2026 maps 3 layers in Joist's stack: Payments / PSP (Stripe Connect); Lending (Joist Lending (Fundbox-powered small business loans), Acorn Finance home improvement financing marketplace and Klarna BNPL (Pay in 3/4, Monthly installments, Pay later)); Accounting (QuickBooks Online).
