Seller Central multichannel tools for eBay, Shopify, TikTok and Walmart

What changed

New multichannel selling tools in Seller Central connect eBay, Shopify, TikTok and Walmart accounts for listings, orders, fulfilment (including fulfil via Amazon) and cross-channel profitability. Rollout is gradual for the US store at no extra Seller Central fee.

Who’s affected

US sellers (gradual rollout). Not available as a UK launch in Amazon’s announcement.

What to do

1. In US Seller Central, open Settings → Multichannel settings (or “Manage all your sales channels”) and connect only channels you already operate.
2. Decide whether Amazon will fulfil off-Amazon orders; if yes, protect FBA cover for Amazon sales with a separate buffer.
3. Keep one shared stock pool in your own system (OmniRestock) so Amazon MCF and channel inventory cannot oversell the same units.
4. UK sellers: treat this as a US-only watch item until Amazon announces UK availability.

Why it matters for replenishment

Policy, fee and inbound changes move the dates and unit economics behind reorder points. Update lead times, landed cost and channel buffers in the same week Amazon publishes the change — not after the stockout.
