Häufig gestellte Fragen
Which ERP is best for eBay?
There is no universally 'best' solution, because the right software depends heavily on sales volume and assortment complexity. For beginners and smaller power sellers, lean tools such as Billbee or DreamRobot are considered inexpensive and quick to set up, while established merchants frequently rely on JTL-Wawi, plentymarkets/plentyONE or 4SELLERS. For very large volumes or multiple sales channels, multichannel platforms such as Actindo or WMS-supported setups come into consideration. The decisive factor is that the vendor actively maintains the current eBay interface and fits your processes.
Do I need an ERP if I only sell on eBay?
With just a few sales per month, stock can still be maintained manually, but as article and order numbers grow this becomes increasingly error-prone. Experience shows that an inventory management system pays off from a few dozen orders per month, because incorrect stock levels quickly lead to overselling, cancellations and negative reviews. An ERP automates the synchronisation of stock, orders and shipping data and thus reduces manual errors. eBay's own tools, such as the Selling Manager in Seller Hub, mainly cover simple use cases and reach their limits with many variants and multiple channels.
How much does an eBay integration in the ERP cost?
Costs vary considerably depending on functional scope, order volume and integration depth. Simple plug-and-play solutions for beginners start in the low double-digit euro range per month, while mid-market setups with repricing, multiple accounts and deeper automation can be significantly higher. On top of that, there are often one-off setup and possibly training costs, as well as ongoing fees for additional modules or API volume. A reliable cost estimate only emerges from a concrete requirements profile, which is why a requirements document covering your own eBay requirements is helpful.
Does the old eBay Trading API still work?
The classic Trading API is still in operation, but eBay treats it as a legacy interface and is deactivating individual fields and calls bit by bit. Older interfaces such as the Finding API and the Shopping API have already been discontinued (decommissioned in early 2025), and the strategic path leads to the RESTful Sell APIs. There, the Inventory API is responsible for items and stock, and the Fulfillment API for orders and shipping. Anyone selecting a new system should therefore look for a vendor that actively supports the modern REST APIs in order to stay future-proof.
How does an ERP prevent overselling on eBay and other channels?
An ERP consolidates all stock in one central data pool as the so-called single source of truth, instead of maintaining separate eBay and shop stocks. When an item sells on one channel, the available quantity is reduced as promptly as possible on all connected marketplaces and shops. This lowers the risk of selling an already sold-out product again, which would otherwise lead to cancellations and poor reviews. The actual update speed, however, depends on the chosen software, the API limits and the configuration.
Which eBay metrics should the ERP keep an eye on?
eBay evaluates sellers monthly (usually on the 20th of the month) and assigns a service status derived, among other things, from the defect rate and the share of items not shipped on time. For the Standard status, the defect rate must not exceed two percent, while considerably stricter thresholds apply to the 'Top Rated Seller' status (a maximum defect rate of about 0.5 percent). A good ERP therefore helps to meet shipping deadlines, report tracking numbers back correctly and respond to negative reviews in a structured way. This keeps the service status stable, which can directly affect visibility and fee conditions.
