The paperless accounts payable process is the same process with paper removed, and it is worth walking through step by step because the change is not evenly distributed. Two steps change a great deal, one changes slightly, and one disappears entirely. Knowing which is which stops a team expecting transformation where there is none and missing the places where the gain is real. This page walks arrival, coding, approval and filing, says what actually changes at each, and is honest about the step that gets marginally harder, because something usually does and pretending otherwise is how projects lose trust.
Arrival changes most: capture instead of opening post
The invoice becomes a record the moment it arrives, with its document attached and its date recorded. In a paper process that record is created later, at entry, and the gap between arrival and entry is where invoices go missing. Closing that gap is the largest single gain.
Coding changes slightly, approval changes a lot
Coding is much the same work against a screen instead of a page. Approval changes completely: it can happen anywhere, it is recorded rather than signed, and it can be chased automatically. That is where the deadline pressure eases. On the worked example on this site, 400 invoices at three touches of six minutes with a 12% exception rate is 134.4 hours a month, $4,300.80 at a $32 loaded rate and $10.75 an invoice.
Filing disappears, and one thing gets harder
The filing step stops existing, which is the visible win. What gets marginally harder is flicking through several related documents at once, which is genuinely easier on paper. Teams solve it with a second screen and it is worth acknowledging rather than denying.
Questions people ask about paperless accounts payable process
Where do the savings actually come from?
Mostly from arrival and approval, not from filing. Filing is the step people picture and the smallest of the three.
Do we need to digitise the back file?
Rarely all of it. Start with new invoices, and digitise history when somebody asks for it, which distributes the effort onto the documents that turn out to matter.
What if a supplier insists on posting paper?
Scan on arrival and carry on. One paper supplier does not make the process paper-based unless the scan is deferred.
