A billable-hours calculation answers three practical questions for work in the Netherlands: how much approved time is chargeable, what that time is worth at the agreed euro rate, and what total appears on the invoice when VAT applies. Dutch invoice rules require the quantity and nature of services and the unit price excluding VAT, so the hours and rate are not background notes. They are invoice inputs.
The calculation also helps separate billable client work from total working time. KVK's hourly-rate guidance uses 230 working days, or 1,840 hours, after 30 days off, and says a starting entrepreneur should be satisfied with charging customers for 50% to 60% of those hours. That benchmark is useful for planning capacity, but the invoice still starts with approved billable hours.
For a taxable Dutch service, calculate the billable subtotal first, then add VAT. The standard Dutch VAT rate is 21%, with special 9% and 0% rates and exemptions for specified goods, services, professions, or activities. Do not treat every invoice as a 21% invoice. The correct VAT treatment depends on the service, customer, supplier status, and transaction type.
Two common exceptions change the invoice total. A Dutch business using the KOR small-business scheme at turnover of €20,000 or less does not charge VAT to customers, does not pay VAT to the Tax Administration, and cannot deduct VAT on business expenses or investments. For services to a business customer in another EU country, Dutch guidance normally reverse-charges VAT to the customer, so the invoice should not include VAT and should state that VAT is reversed.
The core formula is billable hours × hourly rate = billable subtotal excluding VAT. If VAT applies, calculate VAT on that service value and add it to the subtotal. For example, a Dutch consulting invoice has 17 approved research hours at €110 per hour and 9 approved workshop hours at €140 per hour. The billable subtotal is €3,130.
At the Dutch standard VAT rate of 21%, VAT is €657.30, so the total client charge is €3,787.30. The invoice should still show the service quantity, unit price excluding VAT, VAT rate, VAT amount, invoice date and number, customer and supplier details, delivery date, and services supplied. It must be sent no later than the 15th day of the month after the service was supplied.
A one-off calculator is enough when you have a final timesheet, a signed rate, a clear VAT treatment, and one invoice to prepare. It is also enough for checking whether a draft invoice uses the right subtotal before VAT. It is not enough when several people log time across tasks, some work is non-billable, or invoices need review before accounting.
For ongoing Dutch client work, connect time capture to the tools where work happens. Everhour embeds tracking controls in supported project tools, syncs project and task metadata, and keeps timesheets and budgets visible inside those workflows. That reduces re-keying before invoices and keeps the hours, billing context, and handoff to accounting aligned.

Multiply approved billable hours by the agreed hourly rate in euros to get the subtotal excluding VAT. When VAT applies, calculate VAT on that service value and add it to the subtotal. Dutch invoice rules require the quantity and nature of services and the unit price excluding VAT, so the invoice should show enough detail to support the calculation.
The standard Dutch VAT rate is 21%, but special 9% and 0% rates and exemptions apply to specified goods, services, professions, or activities. Use the VAT treatment that fits the service and customer. If the supplier uses the KOR small-business scheme at turnover of €20,000 or less, it does not charge VAT to customers.
No national statutory increment is listed in Dutch invoice guidance. Dutch invoice rules require the quantity and nature of services and the unit price excluding VAT, but official national guidance does not prescribe a 6-minute, 15-minute, or other time-billing increment. Set the increment by contract, engagement letter, or profession-level practice.
A Dutch invoice must be sent no later than the 15th day of the month after the service was supplied. Required details include the invoice date and number, customer and supplier details, VAT ID, VAT rate, VAT amount, delivery date, services supplied, and quantity. Late internal approval can push the invoice past that statutory deadline.
If no B2B payment term is specified, the payment term is 30 days. The legal B2B term is 60 days unless a longer term is demonstrably not harmful. Large companies must pay SMEs and self-employed professionals within 30 days, and governments must usually pay within 30 days.
Everhour integrates with major project management and accounting tools, embeds tracking controls in supported workflows, and syncs project and task metadata into one time layer. Teams can track time inside tools such as Asana, ClickUp, Jira, Monday, Notion, Trello, and others, then keep billing context available for review.
Everhour lets admins mark projects as billable, set hourly project or member rates, and mark specific tasks as non-billable inside a billable project. Reports can show billable time, non-billable time, billable amount, and cost, which helps separate invoiceable service value from internal work.
Track approved hours inside project workflows, keep billable context attached to tasks, and hand clean time records to billing. Everhour connects daily work to Dutch invoicing preparation.
