How to Run a Weekly Review That Catches Unbilled Hours Before They Disappear

Unbilled hours do not disappear all at once. They leak out in small amounts, a session you forgot to stop, a task you logged under the wrong project, a rate that never got set. By the end of the month, the total is real money and there is no clean way to recover it.

A weekly review catches these things while they are still fixable.

Pick One Time and Protect It

This review works best at the same time every week. Friday afternoon before you close down, or Monday morning before client work starts. The exact time matters less than the consistency. You need it to be a habit, not a decision.

Blocking thirty minutes is enough. If you are doing it right, it rarely takes the full thirty.

Open the Current Week in Time-Trak

Start by pulling up the week's sessions in Time-Trak. Scan for anything that looks wrong before you dig into details. Long sessions with no task category. Sessions with a zero rate. Projects that should have activity but do not.

These visual oddities are the first thing to fix. A session with no category cannot be invoiced cleanly. A session with a zero rate will not show up on the invoice at the right amount.

Fix both before you move on.

Check Every Project That Had Client Contact

For each client you communicated with this week, confirm there is a corresponding time entry. Emails, calls, Slack threads, and review sessions all count as billable time if your agreement covers them.

This is the category that leaks most often. Communication time is easy to do and easy to forget to log. Go through your sent emails or calendar for the week and compare them against your Time-Trak sessions. Look for gaps.

If you find a gap, add the session now while you still remember the context.

Verify Rates on Any New Tasks

If you added new task categories or started a new phase this week, check that the billing rate is correct. New tasks sometimes inherit a wrong rate from a template, or get created in a hurry without one set at all.

A task with the wrong rate will invoice at the wrong rate. That is either lost revenue or an awkward correction conversation with the client.

Review the Budget Status on Active Projects

If any of your projects have a budget cap set in Time-Trak, check where you stand. Are you close to the ceiling? Has the client asked for additional work that has not been formally scoped yet?

Knowing this on Friday gives you time to have the conversation before the next week's work starts. Running past a budget without warning is one of the fastest ways to damage a client relationship.

Mark the Week Complete and Note Anything Pending

At the end of the review, make a short note of anything that could not be resolved this week. A session you are not sure how to categorize. A rate question you need to confirm with the client. A project that had no activity but should have.

These carry forward into next week's review. They do not get forgotten.

What This Habit Actually Costs You

The review takes thirty minutes a week. Fifty-two weeks a year, that is twenty-six hours.

One disputed invoice, one missed billing period, or one project where the rate was wrong the whole time costs more than that. Usually much more.

The review is not busywork. It is the maintenance that keeps your billing accurate without requiring a major audit at the end of every month.

Set the time. Do the review. The money you stop losing is the return on that investment.

Track your time, bill every minute.
