A receivable becomes useful funding only when its cash path is understood.
The first reconciliation I remember clearly was not especially large. A supplier had received money from a customer, but the remittance covered several invoices and a deduction that nobody in our accounts team could explain. I had treated the bank receipt as the end of the task. My supervisor asked me to show which balance would remain after the allocation. I could not. That distinction between money arriving and a transaction being understood has stayed with me through a career in receivables finance.
I want our funding forecast to describe a sequence of events somebody can verify. An invoice amount, an expected payment date and an eligible borrowing asset answer different questions. When those answers are compressed into one cash figure, apparent certainty grows faster than actual control.
