The verdict in three sentences
A 150-employee SME processing 1,200 paper expense claims a month ties up more than 300 hours monthly across employees, managers and accounting. Off-the-shelf software at €5 to €12 per user per month is enough if your expenses are simple; a custom workflow integrated with your ERP at €12,000 to €30,000 excl. VAT becomes more cost-effective when you need to allocate costs by project, site or cost center. Either way, compliant digital archiving lets you discard paper receipts and cuts processing time by a factor of seven.
The real cost of a paper expense claim
The cost of an expense claim never shows up in the budget: it is spread across everyone's time. Here is the 2026 order of magnitude measured in manufacturing and services SMEs, step by step.
| Step | Paper process | Automated process |
|---|---|---|
| Entering and attaching receipts (employee) | 6 min | 1 min (photo and OCR) |
| Manager approval | 2 min | 0.5 min (on mobile) |
| Expense policy check (accounting) | 4 min | 0.5 min (exceptions only) |
| Bookkeeping entry and recoverable VAT | 2 min | 0 min (automatic export) |
| Filing and archiving | 1 min | 0 min |
| Reimbursement by bank transfer | 1 min | 0.2 min (batched SEPA file) |
| Total per claim | 16 min | 2.2 min |
Across 1,200 claims a month, the paper process takes 320 hours, against 44 hours once automated. Less visible losses add up too: VAT not recovered for lack of a compliant receipt (often 1 to 3% of amounts), 3 to 6 week reimbursement delays that frustrate field staff, and policy breaches spotted too late.
Off-the-shelf or custom workflow: the 2026 comparison
| Criterion | Off-the-shelf (SaaS) | Custom ERP-integrated workflow |
|---|---|---|
| Cost for 150 users | €5 to €12 per user per month, i.e. €9,000 to €21,600 a year | €12,000 to €30,000 one-off, then hosting and monitoring (order of magnitude €200 to €600 a month) |
| Receipt OCR | Included, 90 to 97% of fields read correctly | Included via a market OCR engine, same accuracy |
| Expense policy rules | Standard caps and categories | Own rules: by site, grade, project, rebillable client |
| Approval workflow | 1 to 2 configurable levels | Multiple workflows, delegations, approval by amount |
| Accounting export | Standard journal file | Direct ERP posting with cost allocation |
| Compliant archiving | Included or optional | Connected electronic vault |
| Time to deploy | 2 to 4 weeks | 6 to 10 weeks |
Custom software is mainly justified when more than 30% of expenses must be rebilled to clients or allocated by project, or when the ERP imposes a cost structure that standard tools handle poorly.
Compliant archiving and the rollout method
In the Netherlands, the tax authority accepts digitized receipts in place of paper originals, provided the digital copy is complete, legible and stored so that its integrity can be checked during an audit. Records must be kept for 7 years under the statutory retention obligation. A certified electronic vault generally costs a few hundred euros a year for this volume.
Rollout follows four steps: turning the expense policy into rules (1 to 2 weeks), configuring or building the workflow and ERP connector (3 to 6 weeks), a pilot in one department of 20 to 30 people (2 weeks), then company-wide rollout with a one-page guide for employees.
Mini case study
Femke, CFO of a 150-employee manufacturing SME in Amsterdam, handles 1,200 expense claims a month, 40% of them tied to on-site client work and rebilled. She chooses a custom workflow at €24,000 excl. VAT, connected to her ERP with allocation by project.

Calculation for finance and managers: time per claim drops from 10 minutes to 1.2 minutes, i.e. 8.8 minutes saved × 1,200 = 176 hours a month. At a €40 loaded hourly cost, savings reach €7,040 a month, about €84,000 a year. Recurring costs (hosting, OCR, vault) stay under €7,000 a year. The project pays back in about 4 months, before counting better VAT recovery and rebilled expenses no longer forgotten.
FAQ
Can we really throw away paper receipts?
Yes, if the digital copy is complete, legible and stored with guaranteed integrity for the 7-year retention period. A compliant solution costs a few hundred euros a year for 14,000 receipts annually.
What automatic read rate should we expect from OCR?
On restaurant receipts, tolls and hotel invoices, 90 to 97% of fields (date, amount, VAT, supplier) are read correctly. Damaged thermal receipts remain the main source of errors, around 5% of cases.
How long until we are operational?
2 to 4 weeks for off-the-shelf software, 6 to 10 weeks for a custom ERP-integrated workflow. The single-department pilot lets you fix rules before company-wide rollout.
Is mileage handled?
Yes, the calculation applies the current tax-free mileage allowance per kilometer and the route can be computed automatically, which removes the 5 to 15% discrepancies common in manual declarations.
What about company payment cards?
Card statements are imported and matched against photographed receipts. In SMEs that use them, this removes 60 to 80% of out-of-pocket expenses and therefore of reimbursements to process.
