Hi Andrea, I have WC Subscriptions active on the website, and that works fine. I have simple subscriptions set up for monthly and bi-monthly subscriptions. So for product A I have 3 products; one off (Simple Product), every month (WC Subscription), and bi-monthly (WC Subscription). They are all selling the same product and should use 1 inventory. As they are set up as separate products Atum inventory adds a new line, with inventory for every product, which means I now need to set inventory and asign stock to these separate products, which is not why I installed ATUM in the first place. I can not change the products as there are already active subscriptions running. What I try is to share stock between multiple products or subscriptions.
