Hours of Operation
  • Proto Systems ships Monday through Friday 9am-5pm, PST.

    • In-stock orders received before 10am Monday through Friday ship same day, unless otherwise noted on the product page.

    • In-stock orders received after 10am ship on the next operating day.

Fulfillment Considerations

  • All orders must be paid in full prior to shipment with payment received by Proto. Issuing a PO does not constitute payment received.

  • Only complete orders are shipped. Orders containing out of stock items will be held until all items can be fulfilled.

International Shipping

  • Duties and taxes are the responsibility of the receiver and are not collected by Proto.

  • FedEx is the preferred shipping carrier for shipments leaving the US. Alternate carriers are not recommended, and responsibility for issues with customs, export/import will be the responsibility of the account holder to resolve.
