Case Study: Rillet Stood Up 40 Payroll Integrations in 5 Days with Finch

How Rillet Stood Up 40 Payroll Integrations in Just 5 Days

Rillet, modern accounting software built for SaaS companies, needed a better way to collect payroll data for its customers. Before Finch, the team relied on accountants to manually download, map, transform, and upload payroll files each month, creating a slow, repetitive, and error-prone process that didn’t match Rillet’s goal of making accountants’ lives easier.

Using Finch’s unified API for the employment ecosystem, Rillet built a single integration that unlocked data from 40 payroll systems. The team had a functional proof of concept in hours and went live in about five days, with integration work estimated to be 7x faster than building a single direct payroll integration; Finch also helped Rillet save substantial developer time while improving the customer experience.
