908 Devices | Manufacturing | 230 | $50M | United States | TriNet HR Corporation | TriNet PEO | PEO (Professional Employer Organization) | 2022 | n/a |
In 2022, 908 Devices deployed TriNet PEO in a PEO (Professional Employer Organization) arrangement to centralize payroll and HR-related workforce administration for approximately 200 employees. The deployment covered the company headquarters in Boston, MA, a satellite office in North Carolina, and a distributed remote employee population, and it established a biweekly payroll cadence for multi-state exempt and non-exempt payroll processing.
TriNet PEO was configured to support core payroll processing, payroll accounting and tax withholding workflows, and benefits and retirement contribution administration. Functional capabilities implemented included biweekly payroll runs, post-payroll general ledger postings, payroll accruals and reconciliations, unemployment insurance and benefit deduction handling, commission processing, and administration of employee stock purchase program offering periods.
The implementation integrated TriNet PEO operations with equity plan administration via an outside Shareworks/Morgan Stanley platform, maintaining alignment of payroll tax withholdings and equity release data between TriNet PEO and Shareworks. Operational workflows required coordination with Finance for bank funding and month-end close tasks, and with Legal and Human Resources for grant approvals and equity plan governance, reflecting cross functional data flows for compensation and stock plan events.
Governance and process changes were formalized through payroll process and procedure documentation, development of training documentation, and designation of a Payroll and Equity Specialist reporting to the Controller to act as the primary internal resource. The role supported escalated employee payroll inquiries, liaison work with external auditors, and operating procedures that reconciled payroll outputs from TriNet PEO with internal accounting controls and equity administration processes.
