Dutch consumer prices were 3.4% higher in September 2026 than a year earlier, up from 3.3% in August. Motor fuels cost 27.2% more year on year. Food prices fell.
Why this matters
Household consumption volume rose 2.1% in August. Retail sales volume rose 2.7%. Even so, customers may question a new rate. Fuel, payroll and supplier bills can rise before prices change on existing jobs. A higher invoice total can still leave less margin and tighter cash. Since 2026, Dutch CPI has used 2025 as its base year. For indexation, follow the index, reference month and calculation stated in the contract.
Example
A maintenance firm runs several vans and has fixed-price jobs. It priced one job six weeks ago. Fuel and supplier costs have risen since then. The customer pays the agreed price. Payroll and fuel must be paid first. If the invoice stays unpaid for 30 days, cash tightens. The job keeps staff busy but leaves less cash and margin than planned. Before changing a price, the owner checks the quote, contract, current costs and customer terms.
XTROVERSO tips
- Check open quotes. List quotes and fixed-price jobs prepared before recent cost increases. Recalculate fuel, materials, freight, payroll and subcontractor costs.
- Split turnover into useful parts. Separate price, sales volume and customer mix. This shows whether growth comes from more work or higher invoice values.
- Read each indexation clause. Record the named index, base year, reference month, notice period and calculation. Do not apply the headline inflation rate automatically.
- Test short-term cash. Map supplier invoices, payroll, tax, customer payments and stock purchases for the next 8 to 13 weeks.
- Give price changes one owner. Set one approval point for surcharges, rate cards and customer messages. Keep the calculation in the customer file.
