Which unified API is right for me?

Finch supports top providers and detailed payroll functionality that Merge can't.
Finch offers 200+ integrations within HRIS and payroll alone. That's 4x* the coverage of Merge.
*Merge includes identity platforms like Google Workspace and Jumpcloud in ‘HRIS’. For the sake of fair comparison, these were not included.
Intuit Quickbooks (21.5%) and ADP Run (11.9%) alone makeup 33% of the US payroll market. Merge doesn’t support either.
Merge is missing earnings, tax, and deductions data for key providers.

Not every unified API will be able to offer the data you need, even if they support the integration. We suggest compiling a list of crucial providers and data fields, and then closely examining field support documentation to ensure proper coverage.
If a unified API accepts new integration requests, make sure to ask for details. How often are requests added to the roadmap? How soon can you expect to connect an employer? With Finch Assist, requested integrations can be added (in beta) in just 7 days.
Merge claims to have write capabilities but today, Finch is the only unified API that can create and manage payroll deductions programmatically.
Request an API key to connect your first 5 employers for free. New connections are just $50 per connection per month.
