Barter process between Contract Account (FI-CA) and Vendors (FI-AP)

Hello experts!
A barter negotiation is intended with a vendor.
He will provide a service and issued an entry invoice, and on the other hand we will provide telecom service by invoincing using Contract Account (FI-CA).

Please could you guide me, is there any way where I might reconcile/clearing accounts payable (vendor) with accounts receivable (contract account)?
