Why payables slip through the cracks
Many small businesses pay suppliers straight from the bank without recording the bill first. That makes the books look fine until someone asks what is still owed, and nobody can answer. When bills are recorded in the accounting system as they arrive, the picture of what the business owes is available at any time, not only after a painful reconstruction.
For your firm, recorded bills also make reconciliation cleaner. A supplier payment that matches a recorded bill is straightforward to confirm, and one that does not stands out as something to ask the client about. That is far easier than guessing what a payment was for weeks after it left the account. Clients also appreciate being asked sooner, while the invoice is still fresh in their memory and easy to find.
