When a hiring manager presses the hire button in your ATS or core HR system, the new employee’s information appears in Paycor automatically — nobody retypes it. Flexspring connects Paycor to any HR app through a direct API-to-API connection, so new hires and employee changes move across in near real time rather than waiting on a scheduled file transfer.
Paycor sends data out as well. Payroll journal entries flow from Paycor into your ERP, summarised into one entry per payroll run per subsidiary and checked for balanced debits and credits, and new hires and employee changes flow from Paycor into your ERP for workforce management. Approved expense reimbursements travel the other way, from your ERP into Paycor.
Flexspring builds, hosts, and monitors the connection for you, and no internal IT resources are needed — Flexspring’s experts do all the custom data mapping, matching the field names and data syntax your apps already use, including custom fields. A custom integration deploys in 10-12 weeks, depending on complexity. Flexspring is a Paycor Marketplace Partner.
Here are the six integration requests Flexspring receives most often for Paycor. Each row names the direction the data travels. With Flexspring, you only pay for the use case or use cases you need. Flexspring also builds custom integrations for one-time payments, banking and tax, expense management, learning management, equity systems, background checks and assessments.

Flexspring iPaaS does not store employee data beyond temporary transaction logs, and meets SOC 2, GDPR and ISO 27001 standards.
Paycor connects to any HR app, ATS or ERP through a custom Flexspring connector. New hires and employee changes move into Paycor from your ATS or core HR system, payroll journal entries and employee data flow out of Paycor into your ERP, and approved expense reimbursements come into Paycor from your ERP. Flexspring builds the integration to match your custom fields and business rules, then hosts and monitors it.
You decide which information you want to sync, and a data integration expert like Flexspring maps every field between the two systems and builds the connection. Custom integrations by Flexspring include unlimited custom fields and unlimited business rules. There is nothing for your team to install or maintain.
With data integration, new hires and employee changes sync, including your custom fields, in either direction between Paycor and your HR app, ATS or ERP.

The best way to connect Paycor to your HR app depends on your data and business requirements. A standard connector can work for simple data flows, while custom fields and unique business rules require a tailored integration. If you go the custom route, you can build the integration yourself or choose a managed integration like Flexspring’s — built and maintained for you, which is typically faster and cheaper.
