Case Study: Montana Municipal Interlocal Authority achieves streamlined payroll and HR efficiency with Sage Intacct

Municipal authority scales peak of payroll efficiencies

Montana Municipal Interlocal Authority (MMIA) is a member‑owned nonprofit that provides self‑funded employee benefits, liability, property, and workers’ compensation coverage to Montana’s incorporated cities and towns. With a small staff of about 33, MMIA faced time‑consuming, spreadsheet‑based payroll, HR, and open‑enrollment processes and a payroll system that didn’t integrate with accounting, resulting in duplicate data entry and limited reporting.

MMIA implemented Sage Intacct Payroll powered by ADP, integrated with Sage Intacct, to create a single source for payroll, HR, benefits, time tracking, and accounting. The rapid rollout introduced employee self‑service and automated workflows, cut manual touchpoints, provided near‑real‑time visibility and audit trails, reduced processing time for payroll and enrollment, and simplified vendor management — with plans to expand into performance and recruiting.
