“Flexspring helped us eliminate manual tasks, making our journal entry process much smoother. Data integration saves us so much time transferring information from ADP to NetSuite — it’s very simple now, and we’ve had no issues. In the past, what took us two hours now only takes 30 minutes!” — Whitney Vaughn, Payroll Specialist, Castle Biosciences
Integration Challenge
Castle Biosciences had a manual payroll journal entry process that consumed valuable time every month. The payroll team manually moved data from ADP into NetSuite for journal entry processing, which took two hours to complete for each payroll run.
As the company grew, doubling its workforce to 1,000 employees, the payroll team urgently needed data automation—manual processes weren’t built for that level of growth. Payroll needed a faster, smoother way to transfer payroll data into accounting without adding more manual work.
Integration Solution
The team partnered with Flexspring to automate ADP to NetSuite journal entries.
With Flexspring’s data connector in place, payroll data now flows from ADP into NetSuite, reducing the manual work required to process journal entries. What once took the payroll team two hours to complete now only takes 30 minutes. That’s a 75% reduction in manual work.
Time saving matters. The payroll team can support twice as many employees with minimal staff. Instead of spending hours manually transferring data, the team can focus on reviewing, organizing, and completing payroll accounting work more efficiently.
Integration Use Case
ADP Payroll Data to NetSuite Journal Entries
After processing payroll, the Flexspring integration seamlessly extracts data from ADP. The integration then automatically imports key payroll details—like earnings, taxes, and deductions—into NetSuite, creating a single journal entry for each payroll run. Summary amounts are organized by account codes, cost centers, departments, or locations for easy tracking. The integration also verifies debit and credit balances, sending notifications if any errors arise.

Also, as Castle Biosciences grows, Flexspring’s data connector keeps pace with the company’s changing payroll requirements, allowing new locations, employees, or additional payroll details to be added.
Coolest Feature of This Integration
One practical payoff is the quality of the data once it flows into NetSuite. The integration gives the payroll team clear, usable data they can work with right away. Instead of sorting through a mass of disconnected information, they can quickly organize payroll details by department, state, or other reporting needs.
“When the data is posted into NetSuite, it’s all laid out clearly,” said Whitney Vaughn. “All I have to do is create a pivot table, and then I have everything I need. Previously, there was just a bunch of information thrown at me. Now, I can organize the employees based on department or state, and I can adjust the pivot table in any way I want.”
