Track time in the same app you invoice from. Log each block of work against a client and project as you go, mark it billable or not, and at the end of the month turn the unbilled hours into an invoice. Logging your non-billable hours too, like admin and finding clients, gives you a record if the Belastingdienst asks about the 1,225-hour criterion.

Is time tracking in Bilio free? Yes, on every plan, including the free Starter plan, with no limit on clients, projects or hours. Can I turn hours into an invoice? Yes. Pick a client and Bilio makes a draft invoice from their billable hours that aren’t invoiced yet: one line per project, or one per day and task, at the client’s hourly rate or your default. You check it and send it. If you delete that invoice, the hours can be billed again. Do I need to track hours for the urencriterium? The law doesn’t say how you keep the record, but if the Belastingdienst asks, you need to make 1,225 hours a year plausible. A log of your hours, billable and not, kept as you go, is the simplest evidence. Indirect hours like admin, sales and training count. Can I set a different rate per client? Yes. Set an hourly rate in each client’s details, and a default for everyone else in Settings › Invoices & emails. Does it work on my phone? Yes. Bilio runs in your phone’s browser, so you can start and stop the timer wherever you are. ## Guides - [Your first year as a zzp’er](https://getbilio.com/for/first-year-zzp) - [Freelancing next to a job](https://getbilio.com/for/freelancing-next-to-a-job) - [How to invoice as a freelancer](https://getbilio.com/resources/how-to-invoice-as-a-freelancer) ## Bilio is also for - [Expat freelancers in the Netherlands](https://getbilio.com/for/expat-freelancers-netherlands) - [Freelancing next to a job](https://getbilio.com/for/freelancing-next-to-a-job) - [Your first year as a zzp’er](https://getbilio.com/for/first-year-zzp) - [Small service businesses](https://getbilio.com/for/small-service-businesses) Get started ## Your first invoice takes four minutes.
