How to use this hourly invoice
- Add one line per task, day or week, and describe the work done.
- Enter the hours as the quantity. Decimals work: 1.5 is an hour and a half, 0.25 is 15 minutes.
- Enter your hourly rate as the unit price.
- Check the total, add tax if you charge it, and set the due date.
- Download the PDF and send it with your timesheet if the client asked for one.
How much detail to include
Clients pay hourly invoices faster when they can see what the time was spent on. One line per task or per week, with a short description, is usually the right balance. A line for every 15-minute block is too much; one line saying “consulting, 40 hours” invites questions.
If a client wants a full timesheet, keep it in your time-tracking tool or a spreadsheet and attach it, or offer it on request in the notes.
Converting minutes to hours
The quantity field takes decimal hours. Divide the minutes by 60: 15 minutes is 0.25, 30 minutes is 0.5, 45 minutes is 0.75, and 20 minutes is about 0.33. Many freelancers round to the nearest quarter hour; whatever you do, be consistent and say so in your contract.
Different rates for different work, such as a lower rate for travel time, simply go on separate lines.
Frequently asked questions
How do I write 1 hour 30 minutes on an invoice?
Enter it as 1.5 in the quantity. 1 hour 15 minutes is 1.25 and 1 hour 45 minutes is 1.75.
Can I use different hourly rates on one invoice?
Yes. Put each type of work on its own line with its own rate, for example design at one rate and meetings at another.
Should I invoice weekly or monthly?
Monthly is most common. Weekly or every two weeks suits long projects or new clients, because it keeps the amount owed small.
Do I need to attach a timesheet?
Only if your client or contract asks for one. Otherwise, clear line descriptions are usually enough.
