The challenge

Staff keyed invoices into the accounting system by hand, then chased approvals over email. Month-end was a scramble.

Our approach

Invoices arriving by email are read with AI extraction, validated against purchase orders, routed for approval in Slack and posted to the ledger, with exceptions sent to a review queue.
