from the beginning of the shop activity we used manual order fulfillment. A month ago our orders started to be fullfiled automatically, although we don't even see the order yet. (It says : Shopify fulfilled order/This order was archived etc.) How did that happen? How back to manual fulfillment?
Great question here! By default, the orders on Shopify are set to be automatically fulfilled but you can change this setting and fulfill it manually. One advantage of fulfilling manually is that you can track your inventory and manage the sending time of an order.
We wrote a guide on how to fulfill orders on Shopify manually. Please take your time to have a look at it and follow the step-by-step guide included in it.
Hope it helps!
You can switch back to manual like this:
1) Go to Settings > Checkout
2) Scroll down and look for this section:
3) Check either the 2nd or 3rd option.
