Track the hours. Bilio writes the invoice.
Start a timer when you begin, or type the time when you’re done. Every hour sits with its client and project, billable or not. At the end of the month, pick the client and Bilio turns their unbilled hours into a draft invoice. No separate timer app, no copying hours across, and it’s free.

What’s the easiest way to track hours as a freelancer?
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.

A timer, or type it afterwards
Start the timer when you begin and stop it when you’re done. Forgot? Add the time afterwards as 1:30, 1,5 or 90m, whichever you think in.
- 02
Per client and project
Every entry has a client, a project and a line about what you did, so the invoice explains itself and you can see where your week went.
- 03
Billable or not
Log the admin, the sales calls and the course too, marked not billable. They stay off your invoices, and you have a record of all the hours you put into your business.
- 04
Hours into an invoice in one click
Pick a client and Bilio makes a draft invoice from their unbilled hours: one line per project, or one per day and task, at their hourly rate or your default. Delete the invoice and the hours are free to bill again.
- 05
Your week at a glance
This week, last week, next: what you logged per day, what’s billable and what’s not invoiced yet.

Four btw returns and one income tax return.
The btw return is due by the last day of the month after each quarter; the income tax return by 1 May the year after. The hours criterion is 1,225 hours a year, and admin, finding clients and training count as well as billable work. Bilio doesn’t decide whether you meet it, but your log is the record you’d show.
