Today since we use bill.com top pay vendor bills, we use their approval flow. So basically an invoice and/or bill comes in, accounting creates it in bill.com and sends it to the approving manager who approves it before it's paid.
So our intent with Odoo is that all POs/Bills are handled in Odoo and the only thing we're using Bill.com for is to send the checks (so we are just pragmatically creating & paying a bill in bill.com but ideally our users don't get in there anymore), the workflow remains in Odoo.
There doesn't seem
to be a way to do any routing there e.g. decide either
manually or rule-based who the PO is routed to for approval. How can we
achieve this?
