TL;DRGood expense documentation is not about creating more administration. It is about capturing the right information at the right time, setting clear standards for foreign receipts and travel allowances, keeping approvals close to the business, and connecting documentation directly to your ERP and payroll.
Few things can drain a finance function more than chasing a receipt that should have been captured from the start. Especially when it comes from abroad, was paid in another currency – and only appears three weeks after month-end close.
For you as a CFO, controller or finance manager, it is not about minor details. It is about reclaiming VAT, maintaining a clear audit trail and having peace of mind when the tax authorities come asking questions.
Here are five tips that make documentation part of your everyday processes – instead of a clean-up exercise that always starts too late.
The classic mistake is delayed registration. Not because anyone intends to do anything wrong, but because people are busy. And when receipts only arrive at the end of the month, it creates bottlenecks and weaker accounting records.
Make it easy to submit receipts immediately – preferably from a mobile device. The closer you get to capturing the expense “here and now”, the less time finance spends chasing, guessing and correcting.
As the saying often goes in practice: It is easier to get it right the first time than to fix it afterwards.
Foreign receipts are often the ones that create the most work – precisely because formats, languages and VAT information vary.
That is why your standard needs to be crystal clear: Employees should always submit the date, supplier, amount in the original currency, as well as VAT amount and VAT rate, if available.
In addition, your approach to currency conversion should be consistent and easy to explain. Not because it simply looks good in a policy document, but because consistency and traceability are what matter when someone reviews your documentation.
Per diems and travel allowances are rarely the largest expenses. However, they are often where questions and discussions arise.
That is why the connection needs to be clear: purpose, destination, travel dates and any deductions for meals provided should logically align and be properly documented.
If you use automated calculations, make sure they are based on your travel policy and the applicable rates – and that the underlying data can be verified.
The goal is consistent handling and less reliance on “gut feeling” during approvals.
Complex approval processes create delays. And delays create workarounds. The best solution is often to let the closest manager approve quickly, while finance defines the framework:
When approval sits with the person who knows the expense best, both the need to chase documentation and internal friction are reduced. At the same time, you maintain control by ensuring rules are clear and applied consistently across the organisation.
Documentation is not just a folder. It is a connected chain. Receipts, coding, approvals, reimbursements and accounting entries should be traceable – even months later.
That is why it makes sense to ensure that data flows directly into your ERP system and payroll, without anyone having to enter the same information multiple times.
The fewer manual steps, the fewer errors. And the easier it becomes to demonstrate a complete audit trail.
When expense management still relies on paper receipts and scattered documentation, VAT and tax compliance becomes a recurring clean-up task.
When the process is digital from the beginning and supported by clear standards, you reduce both risk and costs: less administration, fewer errors and documentation that can easily be found and explained.
Ultimately, this is what strengthens the role of the finance function: less time chasing receipts and more time spent on what actually matters.
