Billable vs non-billable hours: a guide for agencies

Billable hours are time you can charge a client for under your agreement, such as work on their project at the agreed rate. Non-billable hours are the rest: sales, admin, training and internal meetings. Track both, because the split decides what you really earn per hour.

For an agency or a consultant, hours are the stock you sell. A team can be busy all week and still have a thin month if too much of that week went to work no client pays for. Knowing the split is the start of fixing it, whether the answer is a higher rate, a clearer scope or fewer internal meetings.

What usually counts as billable

The honest answer is "whatever you agreed with the client". Write the rules down in the engagement letter or statement of work, and use the same rules on every timesheet. The table shows where many teams land.

Activity	Usually billable?	What decides it
Work on the client's project	Yes	The agreed scope and rate
Client meetings and calls	Usually	Whether the agreement includes them or caps them
Travel to the client	Sometimes	Many firms bill travel at a lower rate or not at all
Fixing your own mistakes	Rarely	Few clients will pay twice for the same work
Proposals and sales calls	No	Cost of winning the work
Admin, training, internal meetings	No	Cost of running the business

Why non-billable hours still matter

Non-billable work is not wasted work. Proposals bring in next quarter's projects, training keeps rates up, and admin keeps the lights on. The point of tracking it is to see how much of the week it takes, and whether that share is a choice or an accident.

The common measure is utilization: billable hours divided by available hours. Someone who works 40 hours and logs 28 of them to client work has a utilization of 70 percent. Many agencies aim for a target well below full time on purpose, because nobody can sell, learn and run the business in zero hours.

Watch the trend rather than one week. A drop over a month often points to something you can fix: a client who keeps asking for unpaid extras, a project that ran past its scope, or a meeting that grew from thirty minutes to two hours.

How to set the rules with your team

1. Write a short list. One page that says which activities are billable, which are not, and which depend on the client. Share it with everyone who logs time.
2. Mark every entry. Each time entry should say billable or non-billable when it is logged, not weeks later when the invoice is due. The guide to what a weekly timesheet entry should capture covers the other fields.
3. Log non-billable work to named buckets. "Sales", "Admin" and "Training" tell you far more than one large "Internal" line.
4. Agree on rounding. Pick one increment, such as six or fifteen minutes, and apply it the same way for everyone.
5. Review before billing. A quick look at the week's entries catches hours on the wrong client. See how a timesheet review step works for one way to organize it.
6. Close the loop. Once the hours are checked, they become the basis of the invoice. The guide to turning tracked hours into an invoice walks through it.

Billable hours on fixed-fee work

On a fixed-fee project, the client pays for the result, not the hours. Track the hours anyway. They tell you whether the fee was right, and they are the evidence you need when a client asks for more than the original scope. The comparison of fixed fee and time and materials explains when each model fits.

On a retainer, hours show whether the client is using what they pay for each month. If they keep going over, that is a conversation about a larger retainer; if they keep going under, it may be a risk to the relationship.

Common mistakes

• Logging at the end of the month. Memory is generous with round numbers and forgets the small calls. Daily entries are more accurate and faster.
• Hiding non-billable work. If people feel judged for internal hours, they spread them across client projects. Your numbers then look healthy while your margins do not.
• Different rules per person. One person bills travel, another does not. Clients notice, and so do your reports.
• No notes. "Design, 3 hours" is hard to defend. "Revised the home page layout after Tuesday's feedback" is easy.

Frequently asked questions

Is travel time billable?

It depends on what you agreed. Many firms bill travel at a reduced rate, some include it in the day rate, and some do not bill it at all. Put the rule in writing before the work starts so the invoice holds no surprises.

Should internal meetings be tracked?

Yes. They are rarely billable, but they take up a large share of many weeks. Tracking them shows which meetings are worth their time and which could be an email.

How many billable hours a week is realistic?

It varies by role. People who sell and manage will bill less than people who deliver. Set a target per role based on your own history, then adjust it as you learn, rather than copying a number from another firm.

Do you charge clients for writing a proposal?

Usually not: a proposal is part of winning the work. Paid discovery or scoping work is different, and many agencies offer it as a small project of its own when the scope is unclear.
