Fast-sync helps to sync the inventory of FBA products from Amazon to Shopify.
On activating fast-sync, Shipr will monitor new FBA orders on Amazon and update Shopify product inventory accordingly. The app will monitor Amazon FBA orders and update the Shopify inventory once every 15 minutes.
Only the matching SKUs will be synced. This ensures that the stock levels on Amazon and Shopify are the same and you don't have to manually update them each time there is an order placed on Amazon.
To activate fast-sync goto Shipr dashboard > Settings > Sync > Activate Fast-sync.
Fast-sync is available on Pro Plan ($20 per month) and above only.
