What Is Finance Process Mapping and Why Should You Do It?

Finance process mapping is a way of documenting how a given task in the finance function moves from beginning to end. A map will outline the steps and the people responsible for them, the systems involved, the information required, where decisions are made, and what happens when things don’t go as intended.

For a finance team, the point isn’t to have a diagram for the sake of it. A properly created map can reveal what’s otherwise hard to spot when everyone is focused on their own part of the process: bottlenecks in the workflow, duplicated effort, unnecessary hand-offs or manual workarounds.

The Australian National AI Centre puts forward process mapping as an effective tool for understanding the flow of work across people, data and technology. In its guidance, the Centre is quite specific about looking for such inefficiencies as rework, inconsistency, over-processing and waiting.

Exactly What A Process Map Is

A process map is a visual representation of how work moves through a business. Take the case of a supplier invoice. The procedure seems simple enough: an email comes in, accounts payable does a check, a manager gives approval, it’s entered into the system and then included in a payment run.

But in practice, there can be a world of difference. Some invoices may come via a portal and others straight to an employee’s inbox. An item might be left waiting while someone awaits sign-off. Finance staff could be pulling data from one place, adjusting it in a spreadsheet and entering it elsewhere. Finance process mapping brings those realities to light.

There’s no need to map every activity in fine detail. It’s better to apply the exercise where there’s a clear reason to.

When Should You Create a Finance Process Map?

1. Persistent Delays

When a task habitually fails to meet its turnaround time, a map can pinpoint the source of the delay. It may not be the finance team’s doing; perhaps an approval is pending in another department, or a system requires manual input. The National AI Centre advises focusing on high-volume processes with defined endpoints that are known to cause frustration.

2. Rework

If staff find themselves correcting data from another team or entering the same figures into two different systems, the map will show where that repetition occurs. The Centre identifies this kind of rework, along with manual entry and information gaps, as prime areas for review.

3. Prior to a System Change

Before a team commits to new technology, it should have a clear understanding of what’s currently in place. There’s always the danger of automating something that’s fundamentally inefficient. Mapping allows one to distinguish between the repetitive steps that can be simplified and those that require human judgement.

This is particularly relevant as companies adopt new tools. ABS figures for 2024-25 indicate that 28% of Australian firms have put in place new processes and 12% are using AI (24% in the financial and insurance sector). While these numbers are indicative of the wider business environment rather than finance specifically, they provide useful context.

4. Nobody Is Quite Sure Who Owns the Work

There’s a tendency for ownership to become unclear in a process that’s passed from one team to the next. An individual might think that another team has a task in hand, or two staff members may find themselves doing the same check without realising it.

Making the hand-offs explicit through mapping will make these gaps visible. It can also identify the occasional instance where one person is the only employee with the knowledge of how to carry out a certain step.

What Sort of Problems Does Finance Process Mapping Uncover?

A good map shouldn’t be a mere formality; it ought to give the finance team a reason to examine the way work is done. You’ll often come across:

• Waiting – work left between stages until someone is available to move it forward.

• Rework – where information must be corrected and processed again.

• Duplicate entry – the same data being entered into more than one system.

• Manual workarounds – staff turning to spreadsheets because the systems won’t communicate with each other.

• Unclear ownership – no one is clearly responsible for a given stage.

• Unnecessary steps – activities that have outlived their original purpose but are still part of the routine.

• Control gaps – an approval or review that should be there is absent.

• Bottlenecks – a stage that regularly holds up the rest of the process.

The causes of such finance workflow bottlenecks vary. A delay in an approval could be a matter of authority, whereas repeated data entry may be an integration issue. Mapping allows one to distinguish rather than treat every delay as a staffing problem. The Australian Department of Finance would agree, noting that a clear view of the work steps and controls makes it simpler to standardise, strengthen controls and remove unnecessary activity.

How Does a Process Map Differ From a Procedure?

They’re related documents but not the same thing. ISO is quite specific: a process is a set of interacting activities to produce a result, while a procedure is the prescribed way to do it.

Consider a finance workflow: an employee submits an expense, a manager gives approval, finance checks and records it, then payment is made. That’s what the process map will show, with its focus on sequence, inputs and dependencies.

The accompanying procedure will go into the method of the task, detailing how the finance employee is to verify the coding on a receipt or deal with missing information. In short, the map is the route and the procedure is how you follow it. They shouldn’t be used interchangeably.

Starting Finance Process Improvement With a Map

When the process is laid out, the team can ask why a particular step is in place. Is it an essential control or just a legacy of how things have evolved? That’s where finance process improvement begins.

A sensible review might follow this order:

• Pick a process that needs attention.

• Define its boundaries and document what actually happens today.

• Include the people and systems involved.

• Note the rework and delays.

• Separate the necessary from the unnecessary.

• Design something better.

The key is to document what’s really happening. A map drawn up to show how a process should run won’t capture the workarounds staff have put in place to keep things moving. The National AI Centre’s guidance is to talk to the people on the ground and find out where the process gets stuck.

Why Does Finance Process Mapping Matter?

It’s easy for a finance team to view their duties as a series of isolated tasks. One person receives the data, another puts it in the books, and a third reviews it. Everyone is doing their job right, yet the overall process is unnecessarily complex.

Finance process mapping brings those activities into one view. It shows the manager where information is delayed and where employees have had to find workarounds. It isn’t the solution in itself, but a means to understand the current process. Done well, it can take a vague concern about a cumbersome process and turn it into clear facts on everything from technology to hand-offs.
