How do inventory management and accounting fit into this?
Orders, invoices, and e-invoices, as well as inventory management with a multi-warehouse system and shipping labels, are all handled within the XONIC Shop System itself. Accounting remains external and is connected in every package: DATEV Rechnungsdatenservice 1.0 transfers outgoing invoices including the invoice image (PDF) to DATEV Unternehmen online (Belege online, Rechnungsausgangsbuch), bundled per posting month, for further processing by your tax advisor. The transfer starts at the click of a button in the backend or in the daily run. The order is exported to Lexware Office, where Lexware Office generates the invoice. The shop issues e-invoices; you process received e-invoices in your accounting system.
If you manage inventory, prices, and customers in an inventory management system such as JTL-Wawi or Xentral, you can integrate it via the xoPort data interface starting with the Professional package. The interface synchronizes products, inventory levels, prices, customers, and orders. The Interfaces page shows which systems are supported.
DATEV Rechnungsdatenservice 1.0 must be ordered from DATEV and set up before use.
One store for B2B and B2C, or two separate stores?
A single store
The customer group determines prices, product range, and whether prices are displayed gross or net. Guests see gross prices, while registered business customers see their net prices and terms. You maintain products, content, and inventory only once.
Two separate stores
The reseller portal and the end-customer store each have their own domain, design, and product range. With the Multishop module—available as an add-on starting with the Professional package—both run on a single installation with a shared product database.
Which approach is right depends on your product range, prices, and processes. We’ll discuss this with you before launch.
What should B2B merchants look for when making their selection?
- Core pricing logic: Customer groups, tiered and net prices, as well as customer-specific prices should be built into the system, not require an additional plugin.
- Taxes and Invoices: VAT ID verification, reverse charge, and e-invoices for business customers must be accurate in every scenario, from the shopping cart to the invoice.
- Inventory Management: Is there a properly maintained integration with your inventory management system, and who maintains it?
- Costs: Fixed prices or a percentage of sales—and what are the additional costs for hosting, updates, and support?
- Support: Who responds in the event of a system failure, and how can you reach them?
You can find a detailed list of questions in the guide “E-commerce Platforms for B2B and Wholesale: These Features Make the Difference.” The e-commerce platform comparison shows how XONIC differs from other systems.

How does the transition to XONIC work?
We’ll transfer products—including categories, variants, and images—as well as customer accounts and orders from your previous store. A standard setup is completed in 1–3 business days; with data migration or a custom design, 2–4 weeks is usually a realistic timeframe. The process and source systems are described on the Data Migration When Switching Shops page. Before that, you can try XONIC for free for 30 days.
