Case Study: SumUp achieves a 30% increase in outbound calling with Aircall

Aircall Helps SumUp Increase Outbound Calling by 30%

SumUp, a Berlin-based fintech founded in 2012 that provides mobile card readers and payment services to millions of small businesses across 31 countries, relied heavily on phone interactions for sales, partnerships and account management. Rapid growth exposed limitations in their previous phone system—slow CTI loading, poor mobile support and insufficient Salesforce integration—hindering sales productivity and adoption of voice outreach.

By switching to Aircall, SumUp gained instant, easy-to-use phone functionality with a mobile app and tight Salesforce integration that eliminated CTI delays, automated call syncs and simplified global number creation. Adoption jumped, phone-based outreach rose by 30%, KPI tracking and call recording improved coaching and reporting, and SumUp plans to roll Aircall out to additional teams.
