Why expense data breaks and how CFOs can keep it clean

If month-end feels chaotic, the real problem often starts weeks earlier.

That was the starting point for a recent Payhawk interview between Asta Pramuditya, one of Payhawk's top Product Marketing Managers, and Robbie Hadfield, GM of Cards and Expenses at Payhawk. We wanted to unpack a problem finance teams know well but often explain too narrowly: Messy expense data.

It is easy to blame volume. Or growth. Or a lack of headcount. But in the interview, Robbie makes a more useful point: Expense data does not usually break because finance teams are doing too much. It breaks because the process around receipts, coding, approvals, and exceptions is still too manual, too delayed, and too fragmented.

That matters more than it sounds.

Because when expense data breaks, finance does not just lose time. It loses context, confidence, visibility, and momentum. Teams spend days fixing issues they should never have inherited. Month-end becomes a scramble. Reporting gets noisier. And finance gets pulled away from the work CFOs actually want it doing, forecasting, planning, decision support, and protecting the business.

Put yourself in the shoes of your top salesperson, Ben. He is thinking about getting to the customer meeting on time and remembering the swag he wants to give away. He's not thinking about cost centre logic, chart of accounts coding, or whether finance will need an extra approval trail three weeks later. If your expense process depends on Ben acting like a financial controller, it's already broken.

That is the real lesson from this conversation? The answer is not to ask people to be more careful at month-end. The answer is to design an expense process that captures clean data at source, automatically routes routine spend, flags real exceptions, and gives finance a better starting point every single day.

The core problem: Month-end does not break at month-end

Here is the big idea up front. Month-end chaos is usually a downstream symptom of poor expense processes upstream.

That is what makes this more than a workflow issue. If receipts are late, coding is inconsistent, approvals are delayed, and exceptions are handled reactively, finance ends up with bad data too late to fix it cleanly. By the time the team is trying to reconcile, the context is gone, and the pressure is on.

For CFOs, this is the aha moment. The bottleneck is not just month-end close. The bottleneck is everything that happens before the close even starts.

This is a truly transformational shift in thinking for CFOs, taking the focus from “how do we survive close faster?” to “how do we stop creating avoidable rework in the first place?”

As Robbie put it:

Month-end is a series of processes around revenue, cost of sales, fixed assets, and intercompany board reporting.

That is exactly why expense data matters more than it seems. It's not an isolated admin issue. It's part of the chain that determines whether finance can move into the work that really counts.

Why we had this conversation now

We sat our experts down for this interview because more finance teams are aiming for a continuous close, or at least a less painful close, but many are still relying on processes built for another era.

Employees submit receipts late. Expense coding is left to people who do not understand the accounting impact. Approvals happen in disconnected tools. Finance chases missing data after the fact. Then the ERP becomes the place where everything gets patched together.

That might still get the books closed, but it doesn't give finance clean, decision-useful information at the speed the business needs.

This is where the conversation closely aligns with one of Payhawk’s core values: Finance needs orchestration, not just integration. It's not enough to connect systems and move data around. You need the right logic, accountability, timing, and controls built into the process itself.

What month-end actually depends on

One of Robbie’s strongest points is that many people in a business do not really understand what month-end is.

They see it as a deadline, whereas finance sees it as a chain of dependencies.

Before month-end can move, reconciliations need to be in place. On the expense side, that means clean accounts payable and bank-side data. If receipts are missing, categorisation is wrong, or approvals are incomplete, those reconciliations slow down. And when they slow down, higher-value finance work cannot begin.

That is why expense data quality matters to CFOs. It is not just about admin hygiene; it's about whether finance can get into reporting, analysis, and decision support fast enough to be useful.

Why the old expense culture fails at scale

Many companies still run on the logic of the "old-fashioned expense report".

Employees collect receipts over time, remember the details later, and fill in the blanks at the end of the month. Meaning? Finance reviews and corrects the problems after the fact.

That model breaks at scale for a simple reason. It asks everyone to care about finance processes at the exact moment they care least.

Your sales guy from earlier, Ben, doesn't want to think about coding during a sales trip. A department lead does not want to revisit a taxi fare from three weeks ago. And finance should not have to become the team that nags the business for missing context at the worst possible moment.

That is why receipt chasing rarely works: It treats a process problem like a discipline problem.

A better model is real-time capture with automation doing the heavy lifting. The closer the expense submission happens to the moment of spend, the more accurate the data is, the easier compliance becomes, and the less repair work lands on finance later.

Robbie summed up the alternative as follows:

If you do processes little and often, you get better compliance, you get better sort of adherence to the policies, you get actual better data!

That line gets to the heart of the issue. Finance teams do not need a better month-end scramble; they need better habits and better systems throughout the month.

Stop asking employees to do accounting work

This is one of the clearest practical insights from the interview.

Employees should not be doing the "full" coding.

They can provide context, check what the system has populated, and upload a receipt. But if your process relies on every employee selecting the right code, dimension, and cost allocation every time, you're creating failure by design.

Modern spend management gives you better options. Coding can be driven by merchant category, supplier, department, location, cost centre, or established rules. AI can populate business reasons and likely categories. Deterministic logic can handle the predictable cases. Finance can step in only where judgment is actually needed.

At Payhawk, the goal is not to build a process with more fields, more rules, and more friction. The goal is to create strong controls without making the process harder for the employee.

And before coding starts, remove the admin altogether...

There's an even better outcome than helping employees code expenses correctly: Removing most of the admin that happens before they need to do anything at all.

For recurring purchases like subscriptions, one of the biggest sources of friction is often the basic document chase. Finance needs the invoice; the employee has to find it, download it, upload it, or send it on. Then the coding and review process can begin.

That is where automation can take another step forward. Instead of waiting for the employee to fetch the document, systems can do that work upstream. With tools like Agent Fetch (part of Payhawk's AI Financial Controller Agent), invoices can be automatically retrieved from supplier websites, reducing manual effort on both sides.

That matters because the less finance depends on employees to remember, find, and forward supporting documents, the cleaner the process becomes. It also means coding, approvals, and accounting treatment can start from a stronger foundation.

What delayed coding really costs

Delayed coding is not just annoying. It is expensive in ways that do not always appear on a dashboard.

First, it creates a loss of context. The longer finance waits to review an expense, the harder it is to understand what happened, why it happened, and how it should be categorised.

Second, it damages trust. If the main interaction people have with finance is being chased for receipts from weeks ago, finance gets seen as reactive and obstructive. That makes it harder for CFOs to position their teams as strategic partners.

Third, it reduces the usefulness of reporting. When too much fixing happens later through journals and manual adjustments, project or department-level reporting becomes harder to read and harder to trust.

This is a useful place to add customer or product proof later. For example, if you have a customer story showing how one team reduced manual recoding, improved reporting accuracy, or shortened close time after automating spend capture, this section would benefit from it.

Exceptions should be the exception

Another strong insight from the interview? How finance should think about exceptions.

Too many teams design expense processes as if every transaction deserves equal suspicion. That slows down everything.

A better principle is to define what normal looks like, let routine spend move through quickly, and focus attention on what sits outside expectation.

This is what good orchestration looks like in practice:

• Routine expenses should follow the normal path with minimal friction
• Out-of-policy or unusual spend should trigger proactive requests, approvals, and flags

Finance should be dealing with the 20% that is genuinely non-routine, not manually handling the 80% that should have flowed through cleanly.

The message is not “automate everything and hope for the best.” It is “automate the routine, surface the risk, and keep accountability where it belongs.”

What accounting-ready expense data really means

This may be the most important operational takeaway for CFO readers.

Accounting-ready expense data should be complete before it reaches the ERP.

If the ERP is where finance still has to repair, reclassify, defer, or clean up spend, your upstream process is not doing enough.

In this interview, Robbie uses the example of subscriptions that need to be deferred over 12 months. Historically, that might live in a month-end spreadsheet. But if that treatment can happen at source in the spend management flow, finance gets cleaner data, less rework, and fewer manual adjustments later.

Robbie explains:

Ultimately, you don't want to edit anything in the accounting system.

That's a strong principle for any CFO reviewing their expense process. If the ERP is still doing too much cleanup, the upstream workflow needs attention.

Not obsessed with processes that 'kind of work ok' already? Think of your ROI instead. Cleaner data at source is not a vague transformation promise; it saves time, reduces manual effort, improves reporting clarity, and helps finance move faster without adding headcount.

How CFOs can reduce month-end rework without hiring

The fastest route is not necessarily the one with fewer people; it's a better process design.

Robbie’s answer is direct. Get the automation right at the source.

That means using rules, AI, supplier logic, and field automation to reduce the time employees spend, improve the accuracy of captured data, and route approvals in a way that aligns with how people already work.

The benefit is cumulative. When employees have fewer fields to complete, fewer mistakes get made. When approvals happen faster, transactions do not pile up. When routine coding is automated, finance doesn't waste time correcting predictable issues. When exceptions are flagged early, risk gets handled before it becomes month-end rework.

This is another place where a product-leader webinar, demo video, or customer story could strengthen the piece. A short example of how a finance team used automation, AI-led coding, Slack or Teams approvals, or real-time receipt capture to reduce manual intervention would make the point more tangible.

A practical framework CFOs can use

If you want to move finance from firefighting to decision support, focus on these five shifts.

1. Capture data in real time

Don't let expenses become a monthly memory test. The closer capture happens to the spend, the cleaner the data.

2. Minimise employee effort

Employees should not be the main coding engine. Give them as little manual work as possible and let automation handle the predictable parts.

3. Build controls around routine versus non-routine spend

Most spend should flow through quickly. Reserve finance attention for the cases that truly need review.

4. Make data accounting-ready before the ERP

Do not use your accounting system as the place where bad data gets repaired. Use upstream processes to send clean, complete, decision-useful data through.

5. Treat close as a process, not an event

Continuous close doesn't start at month-end. It starts with cleaner daily habits, better workflow design, and stronger orchestration.

What CFOs should take away from this

If you are leading a finance team and month-end still feels like a fight, the useful question is not “how do we push people harder at close?”

It is this:

Where is our expense process still relying on memory, manual effort, and after-the-fact correction?

That is the real lever.

Once you see that, the path gets clearer. You stop treating receipts, coding, and approvals as small admin issues. You start seeing them as the foundation for better reporting, better forecasting, and better use of finance time.

Asta explains:

Clean expense data is not just operational hygiene. It's what really frees finance to become more strategic.
