When a new employee is hired or an employee record is updated in Bob, the data appears in ADP Celergo automatically — nobody retypes it. Flexspring connects HiBob directly to ADP Celergo, so new hires, employee updates, transfers, terminations, rehires and banking information land in payroll in real time, along with recurring and one-time payments, approved expense reimbursements and the country-specific data your local payroll teams need. Your team gets fewer payroll corrections, faster onboarding, and an end to double-data entry between HR and global payroll.
Flexspring builds, hosts, and monitors the connection for you, and is one of the leading sellers of data connectors for ADP. There are no files to upload and nothing for your team to maintain. A custom integration goes live in 12–16 weeks. With Flexspring, you only pay for the use case or use cases you need.
