How Cledara used accounting integrations to grow new business ARR by 3x quarter over quarter

View case study

We increased new business sales by roughly 3x quarter over quarter, and the integrations we’ve added through Merge are a big reason why. Finance, IT, and HR teams no longer have to spend so much of their time on the tedious and manual tasks that come with procuring and managing software and onboarding and offboarding employees.
