About

Merge is one API to add hundreds of integrations to your product.

Merge handles the full integrations lifecycle — from an easy initial build taking just weeks, to providing integration observability tools ensuring customer delight, and fully owning the maintenance of integrations.

Thousands of companies use Merge to power their integrations, enabling them to unblock sales, reduce customer churn, accelerate time to market for new products, and save engineering costs and resources.

How we integrate software

Merge integrates the software world

We all use software everyday, but most of this software isn't integrated.

That's because building software integrations has traditionally been hard — lengthy development time and long-term maintenance costs create huge roadblocks.

We envision a future where all software is integrated together, making our work lives more productive and expanding the potential for new software solutions. We built Merge so developers can integrate fast and integrate once.

Trusted to Power Integrations Globally

Thanks to the exceptional support by the Merge team, BILL launched 40+ HRIS integrations, allowing our engineering team to focus more on our core products. Merge also contributed amazing ideas on how to effectively promote the launch.

It takes my team a matter of an hour or less to identify and address integration issues using the Merge Dashboard. Previously, it may take them up to 5 hours.

People think that getting the integrations set up will take a quarter. With Merge, we just onboarded a $250M-revenue brand in two days.
