# Legal time tracking: a practical guide for small firms

Good legal time tracking means recording time against a matter as the work happens, with a short narrative a client could read, and reviewing the data weekly. The goal is not only accurate invoices but knowing which matters and tasks are profitable, which are not, and where your hours actually go.

## Key takeaways

- Capture time at the moment of work; reconstruction at month end loses hours.
- Every entry needs a matter, a duration and a narrative a client would accept.
- Review unbilled time weekly, not monthly.
- Time data is also practice data: use it to price, delegate and decline work.

## What makes a good time entry?

- A matter it belongs to, so nothing floats unassigned.
- A date and duration, rounded using the increment in your engagement terms.
- A narrative that says what was done and why, in plain words.
- A flag for billable, non-billable or fixed fee work.

Check your fee agreements and local professional rules on billing increments and narrative detail.


## How do you build the habit?

1. Log as you go: Add an entry at the end of each task, not at the end of the day.
2. Use one place: A single time log linked to matters. MatterOS includes a time database with matter-level views.
3. Run a Friday review: Check for gaps against your calendar and sent email.
4. Close the loop before invoicing: Review unbilled time per matter, edit narratives, then invoice.


## What can the data tell you?

| Question | Where to look |
| --- | --- |
| Which matters take more time than expected? | Time by matter against the estimate you gave |
| Is fixed fee work profitable? | Hours on fixed fee matters against the fee |
| Where is non-billable time going? | Time by category |
| What is stuck unbilled? | Billable entries not yet on an invoice |

MatterOS tracks time by matter but does not produce invoices or run trust accounting; pair it with accounting software for those.

## FAQ

### How often should lawyers record time?

As close to the work as practical. Many lawyers log after each task, then review weekly.

### Should I track time on fixed fee matters?

Yes. Without it you cannot tell whether the fixed fee was profitable or how to price the next one.

### Can Notion track billable time?

Yes, through a database of entries linked to matters, with views and sums. It is a log, not a billing engine.

### What should a time narrative say?

What you did and its purpose, in enough detail for the client to understand the charge. Follow any rules or client billing guidelines that apply.
