Best practice in going paperless is largely a matter of order. Most projects begin with a scanner and produce images nobody can act on, alongside a tracking spreadsheet that quietly becomes the real system. Building backwards, from the record outwards, means each step has somewhere to deliver when it arrives and each delivers value on its own rather than waiting for the whole project.
Design the record first
Decide what an invoice record holds, which statuses exist and who owns each. Everything else feeds this. Skipping it produces images in one place and a spreadsheet in another, and within a month the two disagree, at which point people trust the spreadsheet and the images become an archive nobody consults.
Move approvals off email second
Approvals on the record, with the document visible at the point of decision and the approval captured with a name, a date and an amount. This delivers the largest single reduction in elapsed time available, and it works while invoices are still arriving on paper, so it does not have to wait for anything else.
Capture third, channels in parallel
With a record and an approval path in place, capture pays back immediately. Consolidating arrival channels comes last in sequence and should start first in time, because it depends on suppliers and colleagues changing habits and takes a quarter or two regardless of what software has been bought.
Keep the annotations structured
Notes, codings and approvals belong as data attached to the record rather than as marks on a scan. A stamped and scribbled image cannot be searched, reported on or corrected without losing history. Keeping the document clean and the metadata structured is what makes the archive useful years later.
Questions people ask about paperless accounts payable best practices
Can we run hybrid for a while?
Yes, and most organisations should. Scanning at arrival with everything downstream digital captures most of the benefit while paper is still arriving from some suppliers.
Should we scan historical invoices?
Rarely worth it. Scan on demand when an old document is actually requested, and spend the effort on the current flow instead.
What about retention obligations?
They attach to the record rather than the medium in most cases, but check your own before disposing of originals, and keep the approval history with the invoice.
