Open Market Advantages

Face facts. OEMs are in the business of manufacturing products and selling those products. They build end-of-sales (EOS) and end-of-life into their products to suit their business model, not yours.

Function5’s business model is based on meeting the hardware acquisition needs of our customers. Period. The certified equipment option exists to fulfill that demand.

The certified equipment option is not burdened with manufacturing quotas, deadlines, or quarterly estimates. The market responds to the demands of enterprise customers and meets that demand with high-quality, low-cost equipment no longer needed by another enterprise entity.
