Purchase Orders issue

Good Morning,

We are very keen to use your solution for Gasbot / Agbot here in Australia.
We have been testing the solution before considering the Pro version moving forward. We do have a launch date of 1 July 2022, but have one issue with the solution.
If the order is created and paid via Credit Card, the Add-in works perfectly, the stock does not adjust until we have completed the order (shipped).
However, if we have B2B customers who settle via PO (Purchase Orders) the add-in does not work the same way. The payment process works as per WooCommerce standard i.e. it reduces stock once the order is created.
Can you advise or create an update to the solution to work for PO (Purchase Orders) too??

Kind Regards
