How to manage Quantity/stock/inventory?

Hi Albert,

Create an event that takes the most recent order, goes through each of the order items, and decreases the quantity accordingly.

Then, put this event into a workflow run at shop|confirmorder|after.

Sincerely,

Hi Albert,

The easiest may be to start from an existing event already dealing with orders and items.

Study it, it's going to guide you.

Good luck
