How to Track Billable Hours for Client Work

How to track billable hours comes down to one rule: the hour has to sit on the piece of work you will put on the invoice. A timer in one app and a task list in another means Friday becomes a reconstruction. You will miss time, and you will not be able to explain a line item if the client asks.

ClickUp can hold the task and the time entry together. Timers, manual entries, estimates, and timesheets are covered in ClickUp time tracking. This page is the billing habit: what to log, what "billable" means in the product, and which plan limit matters before you send an invoice. The ClickUp hub links pricing and the client setups this depends on.

How do you track billable hours?

A billable hour is time you are willing to show a client, tied to their work, with enough detail to defend it. A non-billable hour is real work you will not invoice: internal admin, rewriting your own template, or a sales call.

The practical loop is short.

1. Put the client in a known place. One Folder per client is the pattern in ClickUp for freelancers and ClickUp for agencies.
2. Track on the task, not on the Folder. "Draft the homepage" with two hours is a line you can explain. "Harbor Studio" with forty hours is not.
3. Start the timer from that task, or add the entry the same day if you forgot.
4. Mark the entry billable or non-billable while you still remember which it was.
5. At the end of the period, read the total for that client and those dates, then invoice from your accounting tool.

ClickUp is not accounting software. It will not replace your invoice. It gives you the hours the invoice is based on.

An owner or admin has to enable the Time Tracking ClickApp before anyone can log time. ClickUp Help says owners and admins are also the people who can set time entries to billable by default for the Workspace. Members can track time. Guests can track time only if an owner or admin has allowed it and the guest has edit or full edit permission on the task.

Where should each hour be recorded?

Record time on the smallest task you would still mention on an invoice. If the client buys a homepage, the tasks might be outline, design, build, and revisions. Log time on those. A single task called "October" hides overruns until the month is over.

Add a short description when the entry might be questioned. "Second round of homepage revisions after the Friday call" is enough. ClickUp Help lists descriptions and tags on time entries as advanced time tracking, in the same group as the billable flag. Those actions share a use limit, described below. Do not skip the note on a disputed entry just to save a click, and do not add a novel on every 15-minute timer.

Time estimates are separate from tracked time. An estimate is what you thought the task would take. Tracked time is what it took. Comparing them after a few projects shows which kinds of work you underquote. Estimates are part of the time tracking feature set described in the time tracking guide. They are not themselves the invoice.

If you forget a block of time, add it manually the same day. ClickUp lets you enter a duration, a date, and a time range on a task. Waiting until the end of the month is how billable hours shrink.

What does each ClickUp plan allow for billable time?

ClickUp Help publishes two different limits. Basic time tracking is creating, editing, or deleting a time entry. Advanced time tracking includes marking an entry billable, adding a description or a tag, editing entries from Timesheets, editing someone else's entry, and tracking time that is not on a task.

ClickUp also says timesheet features and plan availability are subject to change, and that you can try newer timesheet features with unlimited usage on any plan for a limited time. Confirm the cap in your Workspace before a monthly close depends on it. The table is the published limit, not a promise that the trial banner will stay.

Prices checked October 2026. Unlimited is $7 per user/month billed annually ($10 monthly). Business is $12 per user/month billed annually ($19 monthly). Enterprise is custom. Full figures are in ClickUp pricing.

The advanced cap is the one hourly consultants miss. Unlimited removes the cap on ordinary time entries. It does not, on the published table, remove the cap on marking entries billable. If every invoice line must be flagged inside ClickUp, read that row before you assume Unlimited is enough. Business raises the advanced allowance to 100 uses. Business Plus and Enterprise list it as unlimited.

Help does not define a "use" here the way it defines a custom field use. Treat the number as a ceiling and check the Workspace if billing depends on it.

Timesheet approvals are a second step: someone submits a timesheet, a reviewer can request changes, and someone approves it. Help places that on Business (100 uses) and on Business Plus and Enterprise. Members can approve timesheets. Only owners and admins can view all timesheets or set approvers. A solo freelancer does not need approvals. A small agency that wants a second pair of eyes on the week does.

ClickUp dashboards places Billable Report and Timesheet cards on Business. Those cards are the on-screen report. The timesheet itself is where you mark an entry billable and see billable and non-billable totals for a date. Use the report when you are on a plan that includes it. Use the timesheet totals either way.

How do you close a billing period?

Do this on the last day of the period, not when you remember the invoice three weeks later.

1. Check that every task you worked sits in the right client Folder. Hours on a task in the wrong Folder will invoice the wrong client.
2. Open Timesheets and filter to that client and the date range. Show billable time. ClickUp's Timesheets Hub can filter by billable status and show billable and non-billable totals for a date.
3. Scan for entries with no description that a client would not recognize. Add the note now, if your plan still has advanced uses left.
4. Copy the total into your invoicing tool. On Business, the Billable Report and Timesheet cards can export as CSV. ClickUp still does not send the invoice for you.
5. For a retainer, compare billable hours with the hours included in the agreement. The gap is either unused time or scope you have not named.

Internal work stays non-billable so it does not land on the invoice and you can still see where the week went. A default of "billable" is convenient for client Spaces and dangerous for an internal Space. Owners and admins set that default. Check it before the team starts logging.

What if you do not bill by the hour?

Still track time for a month if you sell fixed fees. You will learn which fees are thin. You do not have to show that time to the client. Mark it non-billable, or keep it in an unshared List.

Skip time tracking if you never look at the numbers. Partial data is worse than no data, because it looks precise. If your work is a personal task list with no clients, Todoist is the lighter tool. The step up, when client work and hours belong together, is the comparison in ClickUp vs Todoist.

ClickUp for consultants is the engagement version of this setup: proposal in a Doc, time on the tasks, guest access for the client. Turn on time tracking, log this week's client work on the tasks, and read one client total before you change plans.
