Integrations are table stakes in the B2B SaaS world

Every B2B software company faces the same challenge: their customers use dozens of different tools that need to work together, and they expect every software provider to offer integrations with their existing vendors.

But integrations don’t have to be a headache

Building and maintaining integrations with each vendor has traditionally been complex, expensive, and time-consuming. We're changing that. Merge lets you integrate with customers’ third party vendors faster and more reliably than ever.
