Non-billable hours are working hours that you cannot bill directly to your client. These include internal meetings, professional development, administrative tasks, business development, or simply breaks. They are the counterpart to "billable hours" and play a decisive role in the profitability of your agency. Even if they do not generate direct revenue, they are often essential for the long-term success and quality of your work.
Definition: What falls under non-billable hours?
Not every hour that doesn't end up on an invoice is wasted. In a healthy agency, there are various categories of tasks that are not directly remunerated:
- Internal organisation: Team meetings, resource planning, emails, and general administration.
- Sales & marketing: Pitches, networking, maintaining your own website or social media channels.
- Professional development: Training, workshops, and learning new tools or technologies.
- Over-servicing: Work on a client project that exceeds the agreed budget and is not charged as a gesture of goodwill.
Agencies need to keep an eye on these hours
For project managers and agency owners, non-billable hours are a double-edged sword. Too many of them squeeze the margin, while too few can lead to long-term overload or a standstill in innovation.
The ratio between revenue-generating work and internal efforts is often referred to as the utilisation rate. Realistic planning always takes into account a certain percentage of non-billable time to avoid idle periods or burnout.

Strategies for optimisation
The goal is not to reduce non-billable hours to zero, but to manage them consciously. Here are three approaches for greater efficiency:
- Record everything – including internal time: Many teams only track client projects. To achieve true transparency, however, you should also log internal tasks in your time tracking software. This is the only way to identify time-wasters.
- Analyse over-servicing: If your team regularly spends longer on projects than estimated, billable time quickly becomes non-billable time. Check whether your quotes are realistic or whether scope creep (uncontrolled expansion of project scope) needs to be prevented.
- Automate admin tasks: Use tools that speed up routine tasks such as invoicing or scheduling to free up more time for creative work.
Finding the right balance
There is no golden rule, but many successful agencies aim for a utilisation rate of around 70–80%. This means that employees spend the majority of their time on paid project work, but there is still enough room for internal development and buffer times.
FAQ
Are non-billable hours always bad?
No. Time spent on professional development, team building, or business development are investments in the agency's future. It only becomes critical when unproductive administrative activities get out of hand.
How do I calculate the cost of non-billable hours?
These costs are part of your overheads. You must factor them into your internal hourly rate so that billable hours are priced high enough to cover all salaries and fixed costs.
Should I track breaks?
Yes, for legally compliant working time recording, break times are important. They are considered non-billable but are mandatory for health and compliance with labour laws.
[.no-toc]Conclusion[.no-toc]
Non-billable hours are inevitable but manageable. Those who ignore them are in the dark when it comes to price calculation. On the other hand, those who record and analyse them properly can streamline processes and ensure that paid work remains profitable. Use modern tools to create transparency and manage your team efficiently.
