Hello,
What I want to achieve is that the Purchase Order doesn't disappear from the Purchase Orders List page when it's been invoiced.
We situations where we invoice BEFORE stock has arrived, but we have custom fields on the Purchase order that need updating.
Once it's archived, it doesn't look like we can edit them any more.
Where do I go to prevent the Purchase invoice from deleting / archiving the Purchase Order?

If you receive invoice from your vendor before you receive the goods you should really look into using prepayment for those cases.
When a purchase order is invoiced it is technically moved from purchase orders to posted purchase invoices and that is by system design. And all your goods should be received before you post the purchase invoice. That is also by design. If you pay before goods is received the system have a prepayment functionality designed for those cases.
If you have both a purchase order and a purchase invoice you need to be very careful not to post receipt of items twice. In general i would not recommend that approach. I would recommend to go with the system designed flows of purchase orders and prepayment.
