We just launched a new app called FIFO - Order & Backorder Manager.
We created this app as we also use Shopify for our Online Shop. Our problem was to identify which orders are ready to be fulfilled and which orders are still waiting for a product to be back in stock (backordered).
Based on custom "Payment Status" rules and physical, digital and reserved inventory the app will let you know which orders can be fulfilled!!
Also nice, you can create picking lists for selected orders and you can print your packing slips, invoices and so on with some integrated apps like: Order Printer Pro, Orderly Printer & Order Printer.
Hope you guys will love this app as we do!
If you have any question, please let me know!
Can this app create notifications to customers based on a manual selection of products in their order on backorder?
We currently have a 3rd party system managing our inventory so there is no way to automate this through shopify so it's very specific.
No actually not 😞 the app will only help you to fulfill your orders in the right order.
But we also created an app called DON ‑ Delayed Order Notifier. This app is emailing your customers about any delays!
I hope this helps you!
