Expense management is still considered an administrative side process in many companies—until you calculate it properly. Expenses, credit cards, receipts, approvals, input tax, audit trails: in total, the process ties up a disproportionate amount of time, causes error costs, and produces data gaps exactly where CFOs actually need transparency.

For 2026, the question is therefore no longer whether Expense Intelligence is relevant, but how its economic effect can be reliably calculated. A central reference point: The 2025 Forrester Total Economic Impact study on Navan shows an ROI of 376 percent over three years with a payback period of less than six months. For CFOs in the DACH region, however, the key is to translate this benchmark into their own, verifiable calculation model.

Where the Economic Leverage Actually Lies

The biggest misconception in investment decisions regarding spending processes is evaluating only the obvious automation. The ROI of Expense Intelligence arises from four components working together:

1. Time Savings in Finance and for Employees Manual expense processes are expensive. In the DACH market, the total cost of a manually processed expense report averages around 48.82 euros. A largely automated process typically costs less than 10 euros per report. The difference is not an abstract efficiency gain, but a direct release of productivity in finance, shared services, and departments.

2. Reduction of Direct Process Costs This includes manual auditing, queries regarding receipts, approval loops, post-processing of incorrect bookings, card reconciliations, and corrections during the monthly closing. Especially in medium-sized companies, these costs are often underestimated because they are distributed across multiple roles and cost centers.

3. Lowering Compliance and Audit Risks Missing receipts, unclear policy application, inconsistent approvals, and non-audit-proof documentation increase the effort in audits and tax reviews. This is not a theoretical risk: it leads to concrete additional costs in finance, with trustees, or in external audits.

4. Better Data Quality and Management Capabilities Expense Intelligence provides not just faster reimbursement, but structured real-time data on spending patterns, policy violations, tax codes, and budget deviations. The value here lies not just in efficiency, but in better decision-making.

The CFO Model: A Sample Calculation for DACH Mid-Sized Businesses

Let’s take a typical company with 1,000 employees, 300 of whom travel regularly or are active with expenses. Conservatively, 6,000 expense reports are generated per year.

Status quo: manual process

• 6,000 reports x 48.82 euros
• = 292,920 euros process costs per year

Target: automated, AI-powered process

• 6,000 reports x 10 euros
• = 60,000 euros process costs per year

Direct savings

• 232,920 euros per year

This calculation is still intentionally cautious. It initially only considers the difference in operational processing. For a CFO-level investment calculation, further cost blocks must be included.

The Hidden Costs of Manual Expense Processes

Error Costs and Rework

Experience shows that manual reports generate higher error rates regarding tax rates, cost centers, receipt allocation, and policy checks. If only 15 percent of the 6,000 reports trigger queries or corrections, and each rework costs an average of 12 euros, additional costs arise:

• 900 cases x 12 euros
• = 10,800 euros per year

Audit and Compliance Effort

Missing documentation or inconsistent approvals prolong internal and external audits. Even with a moderate additional effort of 120 hours per year in finance and with the trustee, valued at an average of 85 euros per hour, this results in:

• 120 x 85 euros
• = 10,200 euros per year

Lost Input Tax

A classic blind spot. Incomplete receipts, illegible documents, or missing mandatory information prevent the recovery of deductible input tax. With an expense volume of, for example, 1.2 million euros per year, even a loss of 1 percent of the potentially reclaimable amount becomes relevant. Calculated conservatively:

• 12,000 euros per year

Slower Monthly Closing

When cards, receipts, and reports are manually consolidated only at the end of the month, it ties up financial resources at a time when speed matters. Applying just 0.2 FTE of additional burden in finance, at a total cost of 80,000 euros per FTE, results in:

• 16,000 euros per year

The Overall View: Building the Business Case

Adding these blocks to the direct process savings results in the following for the sample company:

• Direct process cost savings: 232,920 euros
• Fewer error and rework costs: 10,800 euros
• Reduced audit and compliance effort: 10,200 euros
• Recovered input tax: 12,000 euros
• Relief in monthly closing: 16,000 euros

Total annual benefit: 281,920 euros

Opposing this are the investment and operating costs for an Expense Intelligence solution. Estimating for a company of this size:

• Implementation and change: 45,000 euros (one-time)
• Software and operations: 72,000 euros per year

• Implementation and change: 45,000 euros (one-time)

This results in the first year:

• Benefit: 281,920 euros
• Costs: 117,000 euros
• Net benefit Year 1: 164,920 euros

The payback period is thus approximately 5 months. Over three years, the ROI increases significantly because the one-time implementation costs disappear. This makes it clear why benchmarks like a 376 percent ROI over three years are not unrealistic in practice.

What CFOs Must Include in the Calculation

Anyone wanting to seriously evaluate Expense Intelligence ROI should look beyond license costs and finance FTEs. Six questions are decisive:

First: How many reports, receipts, and card transactions actually occur per year?

Second: What are the current total costs per report—including departments, finance, and management approvals?

Third: How high are the error rates, rework, and exceptions?

Fourth: How much input tax remains unused due to poor receipt quality?

Fifth: What additional effort is caused by audits, tax reviews, and monthly closings?

Sixth: What is the value of better data for management, policy enforcement, and liquidity planning?

This is exactly where the difference lies between simple process digitalization and true Expense Intelligence. The economic effect is created not only by less manual work, but by cleaner data, better control, and faster decisions.

For CFOs in DACH, this is the relevant perspective: not tool implementation, but return on investment. And that can be calculated.
