Case Study: Olde Thompson achieves 99% on-time, in-full deliveries and frees $10M in operating capital with Plex Systems

Olde Thompson Spices Up Forecasting And Heats Up Growth With Plex

Olde Thompson, an Oxnard, CA–based leader in salt and pepper mills and private‑label spices, outgrew an aging, heavily customized SQL/UNIX ERP that offered no forecasting, poor visibility into costs and suppliers, and growing operational risk. Facing aggressive growth in foodservice and retail, the company needed a scalable cloud platform to improve planning, traceability, and supplier coordination.

Olde Thompson implemented Plex’s cloud ERP and Plex DemandCaster for supply‑chain planning, enabling real‑time shop‑floor data, EDI onboarding, forecasting/MRP, and faster recalls. Within months it cut inventory (20% after 9 months, 35% in 18 months), freed up roughly $10M in operating capital, and achieved nearly 99% on‑time, in‑full deliveries—driving new business and capacity without proportional headcount or facility expansion.
