ADP Celergo with Any Core HR Integration Guide

With data integration, your core HR system is the source of record and ADP Celergo is the target. As soon as an employee is hired or a record is updated in your core HR system, new hire and employee data, banking information, transfers, terminations and rehires sync into ADP Celergo with the information payroll needs. Payments, deductions, approved expense reimbursements and country-specific payroll data travel the same way. Flexspring builds the integration to match your custom fields and business rules, then hosts and monitors it.

Country-specific payroll data syncs from your core HR system into ADP Celergo, so every field a local payroll run requires arrives in one place. That keeps global payroll and HR data aligned across countries without anyone rekeying local fields. Flexspring maps your field names, including custom fields, so the data matches how both systems are set up.

With data integration, new hires and employee changes sync, including transfers, terminations and rehires, plus direct deposit details, all moving from your core HR system into ADP Celergo. Recurring and one-time payments and deductions reach ADP Celergo as well, covering bonuses, company stock shares and other monetary awards, along with approved expense reimbursements such as travel, mileage and cell phone, and the country-specific payroll data each local payroll run requires. You can also add banking and tax, expense management, learning management, equity systems, background checks and assessments.

Flexspring builds, hosts, and monitors the connector. A custom integration for any core HR system with ADP Celergo is fully deployed in 12-16 weeks, depending on complexity. 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 an employee is hired or their record is updated in your core HR system, the data appears in ADP Celergo automatically and nobody retypes it. That puts an end to double-data entry between HR and payroll.

The best way to connect your core HR system to ADP Celergo 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.
