About us

Good questions.

Our answers.

What is DiVA?

DiVA is a fully integrated and highly automated ERP system for e-commerce and omnichannel commerce based on Microsoft Dynamics 365 Business Central (BC). As a cloud platform, we rely on Microsoft Azure.

For which industries is DiVA suitable?

Our focus is 100 percent on one industry: e-commerce and omnichannel commerce in the DACH region (Germany, Austria, and Switzerland). For over 20 years, we have been intimately familiar with the enormous dynamics and complexity of online commerce as focused specialists and are also very knowledgeable about the needs of retailers.

Is DiVA only usable for webshops?

No. DiVA is designed as an omnichannel ERP backend and supports the integration of all sales channels such as webshops, marketplaces, physical stores, mobile applications, telephone sales, and catalogs or newsletters as purchasing triggers.

How many orders can DiVA process?

DiVA can easily handle more than 50,000 customer orders per day in real operation, making it an ideal choice for businesses that expect a high volume of orders during peak times like Black Week.

Can DiVA be integrated into existing system environments?

Yes. DiVA standardly meets the requirements of over 50 of the top 500 German brands and can be used as a standalone platform for all CRM, PIM, or WMS processes. However, there can be individual specificities where other solutions are more sensible. Therefore, DiVA is not set up as a monolithic system but also offers integration possibilities with other CRM, WMS, or PIM systems.
