Ramp and The Second City: AP automation success story

Before partnering with Ramp, The Second City faced challenges with outdated payables processes. Its existing system involved clunky workflows, slow approvals, and a lack of real-time financial insights, which hindered operational efficiency.

‍

Ramp Bill Pay transformed how The Second City managed invoices and vendor payments by automating invoice processing and approvals. Ramp eliminated manual bottlenecks, ensured timely payments, and integrated with the company’s ERP to streamline workflows so the finance team could focus on strategic tasks. As Frank Byers, Controller at The Second City, shared:

‍

“When we moved to Bill Pay, I was hesitant because we were promised the same type of functionality as our previous technology, which didn’t work. But Ramp’s OCR works seamlessly—it not only recognizes the vendor but reads each individual line item and uses accounting rules to code them correctly. That made adopting Ramp Bill Pay a no-brainer.”

‍

And the results were undeniable:

• 2x faster processing: Freed up valuable team resources
• $40,000 annual savings: Streamlined systems generated meaningful savings
• 8-day efficiency gain: Faster expense reporting eliminated delays

‍
