About Optimizers

Optimizers is a medium-sized enterprise located in Nijkerk, The Netherlands. At Optimizers we work on B2B and logistics software.

With the App4Sales platform; App4Sales, App4Customers and Core-portal, we have developed very effective B2B applications for your sales representatives. These applications enable your field staff to access your entire digital catalog and easily place orders for your customers at any location. The App4Sales platform is connected to your back office, which means you can always access accurate customer and real-time item and stock information.

At Optimizers we also developed a Warehouse Management System called WarpSpeed. Extend the boundaries of your company’s performance in logistics with this WMS. WarpSpeed enables you to model your own logistic processes and offer it to your employees as a workflow. Integration components such as label printing, EDI, reporting and KPI dashboarding are built into the system. With this web-based technology, which is connected to your ERP, WarpSpeed gives you an advantage on your competitors!

The EDI Gateway is an Exact Certified module for Exact Globe and Exact Online users. The power of the EDI Gateway is fully handling transactions within the database of Exact Globe and Exact Online. With the EDI Gateway we offer a flexible solution for electronic data interchange that provides the exchange of business documents to optimise chain cooperation.
