Central Payment Question

Our company operates as a shared service using the central payment functionality.
Â
We had a scenario that our company that processes central payments entered in an invoice to be paid to a supplier, and one of the children companies entered in the same invoice. So we double paid a supplier, but lucky for us they informed us of the issue and sent us back one of the two checks we had sent them.
Â
What appeared to happen is that the invoice that was transferred from our child company to our parent company had a “0”, added by the system, to the end of the invoice number, so it seemed as there were two separate invoices. (Per Epicor this is the intended functionality and we have an enhancement request in to Epicor to change this)
Â
My question for those in a shared services company using central pay, what kind of mitigating control do you use in order to assure that we can catch this before we send two checks to a supplier again?
