About Merge
What is Merge?
Merge is a unified API platform that lets developers connect their SaaS application to over 150 HR, payroll, and accounting systems—including BambooHR, Gusto, QuickBooks, and Workday—using a single integration. Instead of building and maintaining separate connectors for each provider, you integrate once with Merge's SDK, and it handles authentication, data mapping, and real-time syncs.
Who is it for?
Merge is ideal for B2B SaaS companies building HR, payroll, or fintech products that need to pull or push data from third-party systems. It's also used by HR platforms wanting to offer pre-built integrations, and AI products that require governed access to enterprise tools. It is less suited for single-vendor integrations where a custom API is sufficient.
Key use cases
Merge streamlines onboarding for employee data, automates payroll runs, syncs invoices between accounting tools, and enables AI agents to act on enterprise data. Trusted by companies like Perplexity and Cledara, it reduces development time from months to days.
Strengths
Merge's unified API covers a wide breadth of systems, manages provider API changes automatically, and offers webhooks for real-time updates. Its self-serve free plan lets you start with 3 production linked accounts for proof-of-concept work.
