The practices that improve accounts payable most are, awkwardly for anybody selling software, mostly free. One arrival address. A status, an owner and an age on everything. Exceptions routed by their reason. Bank detail changes verified through a channel you already hold. Statements reconciled for the suppliers who send you the most invoices.
Make the queue visible
A short fixed list of statuses, a named person rather than a team on each item, and an age from when it entered its current state. The weekly routine is then chasing the oldest three items in each state by name, which is a short conversation rather than a list sent to everybody about everything.
Put resolution next to the knowledge
Price variances belong with purchasing, missing receipts with whoever takes deliveries, supplier problems with whoever maintains records. Payables acting as intermediary for all of them is slow and keeps the resolution furthest from the person who already knows what happened, which is why exceptions age.
Protect the payment step
Release of a run by somebody other than its preparer, and verification of bank detail changes through contact details you already hold, by somebody other than whoever received the request. Both controls lapse most often during absence rather than by design, so the cover arrangement matters as much as the rule.
Reconcile statements for your busiest suppliers
The practice most often skipped and the most reliable way to find invoices raised against you that never reached your system. Prioritise by document count rather than by value, because errors accumulate per document, and treat every difference as a question rather than an instruction.
Questions people ask about best accounts payable practices
Which practice should we start with?
Consolidating arrival channels, because it is free and it closes the largest leak. After that, routing approvals to named people with automatic cover.
How much of this needs software?
Very little at modest volume. Software matters when several people edit the record, when documents must be attached, or when the history must be trusted a year later.
What should we report upward?
Counts by status and the age of the oldest item weekly, and the exception reason mix monthly. The second is what changes other departments' behaviour.
