When you write, include your store's .myshopify.com domain and, if it's about a specific import or sync, the supplier's name and the time it ran. The history page has a link to each run you can paste.

Common problems

• An import stopped. Open the supplier: the notice says why (empty file, far fewer rows, too many products removed). If the file is right, use Import anyway.
• Products don't match. Check the SKU column mapping, and the supplier's products explorer, which lists the rows that found no product in your store.
• Quantities look wrong. Look at the sync's rules and the worked example under them; the run's report shows the quantity before and after for each variant.
• Emailed files aren't picked up. Confirm the store's MostStack address in Connections and that the supplier's own address is on the supplier. Forwarded emails count as the supplier's, however they're forwarded.
