Quality. Service. Integrity.

Too often, the pressure to secure quality, affordable parts and timely delivery results in steep order quantities and excess inventory for the purchasing business.

We’re not in the habit of burdening our business partners with needless overstock. Instead, we adapt production to your preference, whether blanket-order release, just-in-time delivery, or Kanban. Need extra flexibility? We’ll hold your inventory and safety stock at agreed-upon quantities.

We keep your costs down by pricing at estimated annual usage (EAU) quantity, not release quantity. As your partner, we’ll be happy to expand capacity and operations to accommodate your growth!
