Softwarekompass

Softwarekompass compares software for the German market: prices, marketplace fees and tax rules (e.g. the margin scheme under § 25a of the German VAT Act) refer to Germany.

Cross-channel stock sync without overselling

One item, several channels: we show which software keeps stock in sync and reserves it for all channels as soon as an order comes in.

Preset: Amazon, eBay, Kaufland and Shopify, 500 orders per month, stock reservation when an order comes in. Everything can be changed.

Sync is not the same as reservation

Almost every multichannel software syncs stock. The difference lies in the timing: if stock is only adjusted after an order has been imported or processed, there's a short window for double sales. Reserving stock when the order comes in closes this gap.

According to the providers, Colly.io, JTL-Wawi (stock reservation by FIFO), Xentral (can be activated per sales channel) and plentyONE reserve stock. Billbee transfers stock changes to all channels after import, usually within a minute; Billbee doesn't explicitly describe a reservation.

Frequently asked questions

How do I avoid overselling on several marketplaces?

With software that manages stock centrally, transfers it quickly to all channels and reserves open orders. Import orders as often as possible and plan a small safety stock for items in high demand.
