Case Study: Petroff Partnership Architects achieves elimination of three weeks of monthly manual processing with Tenrox

Petroff Partnership Architects - Customer Case Study

Petroff Partnership Architects is a 50+-year-old architectural firm with 138 employees across Markham, Toronto and Shanghai, serving major retailers and institutional clients. The firm relied on a DOS-based accounting system and a proprietary web time tracker that were not integrated, forcing manual re-entry of timesheet data into billing and payroll, creating about 7,500 invoices a year and requiring roughly three weeks of staff time each month for invoicing and payroll with no easy project reporting.

Petroff implemented Tenrox On‑Demand to integrate time, billing and payroll while keeping web access for users; the system automates timesheet forwarding, enforces budget rules with notifications, and provides on‑demand project reports. The change eliminated three weeks of manual processing monthly (saving the equivalent of about $45,000 annually and one full‑time admin role), reduced errors, and gave managers instant visibility into project status.
