Hi northwestflies ,
Thank you very much for your reply.
We were looking at this option in the past, however, extending above 30 days may create a lot of issues for users with lot of sales. It would mean a tons of calculations for the Stock Central on every page load. Servers would cause time out or similar issues.
However, WooCommerce is due to bring out a massive speed improvements so we will review the options then.
PS: the other option would be waiting for our Inventory Coach premium add-on that I hope to bring late 2020.
I apologise for any inconvenience caused.
