Importing products will immediately check your cart for any new products in your inventory and make the appropriate updates to your FetchApp inventory.
The order importer will check your carts and/or payment gateways for any new orders, import them into your FetchApp account, and immediately send the download email to your customers. You will be emailed with the results when the process is complete. The shorter the time frame you choose to check, the faster the process will go.
