Self-billing, also called auto-invoicing, is an arrangement where the buyer issues the invoice on behalf of the supplier, instead of waiting for the supplier to send one. The buyer calculates what is owed, generates the invoice, and the supplier simply accepts it. It is common in construction (BTP) and transport, where the buyer holds the data on what was delivered or performed.
Self-billing speeds up the payment cycle and reduces missing-invoice friction. But it quietly shifts a control risk onto the buyer: if the buyer generates an incorrect invoice (wrong price, wrong quantity, a rate that does not match the contract) there is no supplier invoice to catch the discrepancy. The buyer is both the source of the figure and the one who must verify it.
That makes automated control essential, not optional. The self-billed amount still has to match the contract, the order, and what was actually delivered.
Phacet supplies that control. The agent that verifies invoices against contract terms confirms each self-billed line matches the agreed rates, the three-way matching agent ties it to orders and deliveries, and the supplier billing control agent flags wrong amounts before payment. Every check is traceable through a native audit trail.
Self-billing puts the invoice in the buyer's hands. Phacet makes sure the buyer gets it right, line by line.
