Etsy automated order and inventory sync only runs once an hour on SKULabs.
Etsy strictly limits developers to a small number of API requests per day. We can only effectively auto-synchronize your orders and inventory every 60 minutes without risking being unable to communicate with your store for up to 12 hours.
If you're concerned about overselling within this hour time frame you can hold reserves of inventory using our inventory rules.
If you need your orders in a hurry, just click the refresh button next to your Etsy order sync and we'll have them in just a few minutes for you.
