Merge

Merge replaces the need to build and maintain separate integrations for dozens of HR, payroll, and accounting platforms. It offers a unified API that connects your app to systems like BambooHR, Gusto, QuickBooks, and Workday with one integration.

What it does

You add Merge's SDK to your app, and it handles authentication, data mapping, and syncs with over 150 third-party systems. It supports common objects like employees, time-off, payroll runs, and invoices. Merge also manages API changes on the provider side so you don't have to.
