Troubleshooting channel sync

If a channel stops syncing or listings look wrong, work through this checklist before contacting support.

Listings are missing on the marketplace

• Check the Sync Log on the channel detail page — look for rejections
• Missing GTIN is the #1 cause of rejection on Back Market, GMC, and Reebelo
• Confirm the product is in the saved filter you assigned to this channel
• Make sure stock is > 0 — zero-stock products are not published on most channels

Credentials expired or revoked

Marketplaces periodically force you to re-authorize. When this happens the channel status flips to Auth Required. Open the channel and click Reconnect.

Prices are wrong

• Check the channel markup % — a 10% markup on $500 shows $550
• Verify currency — some channels only accept specific currencies per region
• Tax-inclusive vs exclusive pricing is set per channel; confirm it matches the marketplace

An order is not coming through

Order import is supported on Shopify natively. Other marketplaces require you to fulfill from their dashboard — Techfleet decrements stock when the unit sells, but the order record stays on the marketplace.
