TriNet Integrations: How to Connect TriNet to Any HR App or ERP

With data integration, TriNet connects to your ATS, core HR, CRM, or ERP. New hires and employee updates move into TriNet from the apps your managers already work in, employee changes made in TriNet flow back out, payroll data reaches your general ledger as journal entries, and non-regular payroll expenses arrive in TriNet from your ERP, time-card, or point-of-sale systems. 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. The connection runs over a near real-time API-to-API connection rather than a scheduled file transfer.

With data integration, new hires sync into TriNet, including your custom fields, along with employee updates from your ATS, core HR, CRM, or ERP. Employee changes made in TriNet flow back out to those same apps, payroll data reaches your general ledger summarized per account, location, and subsidiary, and non-regular payroll expenses reach TriNet from your ERP, time-card, or point-of-sale systems. You can also add one-time payments, banking and tax, learning management, equity systems, background checks, and assessments.

Flexspring builds, hosts, and monitors the connector. A custom integration of the Flexspring connector for TriNet goes live in 8-10 weeks. The payroll general ledger use case comes in two forms — a simple connector for payrolls involving a single subsidiary, and a complex connector for payrolls mapped to multiple subsidiaries. Custom integration by Flexspring includes unlimited custom fields and unlimited business rules. Flexspring does all the data mapping, so no internal IT resources are needed.

Flexspring does not store employee data beyond temporary transaction logs, and does not require anyone to handle the data manually. Flexspring meets SOC 2, GDPR and ISO 27001 standards.

No internal IT resources are needed to create your data integration. Flexspring’s team builds the integration to your requirements and monitors it afterwards, including handling API changes from either vendor. Your part is deciding which use cases you need and confirming Flexspring’s recommendations for how your fields should map.

With data integration, when a hiring manager presses the new hire button in your ATS or core HR system, the new employee’s information appears in TriNet automatically — nobody retypes it. Your team gets fewer payroll corrections, faster onboarding, and an end to double-data entry between TriNet and the rest of your stack.

The best way to connect TriNet to your HR apps 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.
