Multichannel fulfilment in Europe one stock pool, every channel

A normal 3PL fulfils orders; a multichannel one fulfils orders from several sales channels against a single shared stock pool and keeps every channel's inventory in sync. The hard part is not the shipping, it is that a unit sold on your website must instantly become unavailable on Amazon and TikTok Shop too. Look for a partner that integrates all your channels at once, not one store with the others bolted on.

Typically your own store platform (Shopify, WooCommerce and similar) alongside marketplaces such as Amazon, TikTok Shop and eBay. Which combinations a partner supports depends on the integrations they have built, so filter for the specific channels you sell on and confirm that stock is shared across them rather than allocated per channel.

Orders from every channel are drawn from the same inventory record, and as stock moves the partner pushes updated availability back to each channel. The result is one number that every channel reads from, which is what prevents the classic multichannel failure of overselling the same units on two marketplaces at once. Confirm how often a partner syncs and which direction the integration runs.

Yes — a good multichannel partner runs each channel's cut-off times and tracking requirements inside one operation, so Amazon and TikTok Shop orders both go out on time from the same warehouse. Tell us the marketplaces you sell on and the matching filters to partners that already hold those SLAs.

The pain of split stock starts at the second channel, not the tenth, so consolidating early is usually easier than untangling silos later. Even with two channels, one shared pool removes the manual stock-splitting and the overselling risk, and it leaves room to add a third channel without changing partner.
