Time tracking for consultants: hours you can explain
Updated 7 min read By David from TimeRetain
Time tracking for consultants is a plain record of client work. It shows the client, engagement, time spent, and work you delivered.
Use that record to explain the month to a client or review your price before the next scoped project.
This guide is for the independent consultant who needs a trustworthy personal record. You don’t need to run a firm to have several engagements in flight.
What consultant time tracking is for
Consultant time tracking answers a few practical questions:
- Which client and engagement did this work belong to?
- Was the time hourly, retainer, fixed fee, or non-billable?
- What did the client get, in words they would recognize?
- Can you explain the entry next week without reconstructing the day?
That’s close to freelance time tracking. Here, the examples focus on retainers and hourly scoped work. Keep a billable record you can explain in a client summary.
If nobody else needs to approve your time, shared approval features add little to this workflow. Start with a timer you’ll use, labels that match how you sell the work, and an export for your billing setup.
The minimum consultant time record
Strip each entry down to what you will need later:
| Field | Why keep it |
|---|---|
| Client | Who pays, or who the work is for |
| Engagement | Project, retainer, or advisory block |
| Date | When the work happened |
| Start and stop | Real duration. Mark a reconstructed block as an estimate. |
| Work note | The result, in client language. This is the line a client might see |
| Type | Hourly, retainer, fixed fee, or non-billable |
| Rate | Only when the hour has a price attached |
A useful note names the outcome: “Mapped current hiring funnel and gaps,” not “Zoom + Notion.” Keep private asides in your own notes. The client-facing line should still make sense on its own.
Here is an example day for a retainer review:
| Date | Start | End | Client / engagement | Note | Type | Total |
|---|---|---|---|---|---|---|
| Aug 3 | 09:00 | 10:15 | Acme retainer | Reviewed Q3 pipeline notes before weekly call | Retainer | 1h 15m |
| Aug 3 | 10:15 | 11:00 | Acme retainer | Weekly advisory call; agreed next hiring screen | Retainer | 45m |
| Aug 3 | 13:00 | 15:30 | Northwind scope | Drafted phase-1 research plan and interview list | Hourly | 2h 30m |
| Aug 3 | 16:00 | 16:40 | Internal | Updated proposal template for fixed-fee work | Non-billable | 40m |
Use those rows in the invoice you already send or to explain a retainer month. This example records two retainer hours, two and a half hourly hours, and 40 minutes of internal work.
Hourly, retainer, and fixed-fee work
Keep the same basic record for these three pricing methods, then change how you use it.
Hourly work needs clean start and stop times and notes that support the invoice. Group lines by what you delivered before you send them.
Retainers benefit from the same record. The hours may not appear line by line on the invoice. The record shows the work you logged against the monthly fee. For a retainer sold as “about eight hours of advisory a month,” compare the hours used with those eight hours.
For retainers with an hour allotment, check during the month. If week two already shows most of that allotment, discuss what work to prioritize before it runs out. Use those totals when you review the scope or price of future work.
Fixed-fee work also deserves a record when you want to review the price. After the engagement ends, divide the fee by all its hours to get revenue per hour before costs. If that falls below your target, look at what took the time. Recurring revisions can call for a higher fee or less included work next time. A one-off problem does not automatically belong in every future estimate.
Before you quote, use the freelance rate calculator to check a fixed fee against planned hours and extra revisions. After delivery, check it again with the hours you recorded.
Keep non-billable work visible. Proposal writing, admin, unpaid follow-ups, and “quick” Slack answers belong in their own labels. Keep client-specific unpaid work attached to its engagement: it still costs time and reduces the effective rate. Mark it separately from hours that count toward a retainer allotment, and keep general business admin separate.
Track travel as a separate entry, even when you leave it off an invoice. The total helps you price future on-site work.
A light workflow for a busy week
Capture first. Clean later.
- Start when the work starts. Pick the client and engagement, start the timer, and write a rough note. Do not pause the work to perfect the wording.
- Stop when you switch. A new client or a non-billable block gets its own entry. Keep small related tasks together, but separate work for another client or unpaid work.
- Clean the same day, then once a week. Rename vague notes while you still remember them. Split mixed entries and check retainer totals against the allotment.
- Review before you share. Use your timesheet to explain the work delivered. Keep unpaid client work visible when you review the engagement, even though you do not bill it.
Keep stored time exact. If the invoice uses hourly lines, you could agree on the rounding method before work starts and round a copy for the invoice. If your method rounds up, three separate 2-minute emails can become three billed blocks, so you might also agree whether to group related tasks first.
Hourly billing shows 6-minute and 15-minute increments you can agree with a client. Timesheet rounding is why the stored hours stay exact.
Optional start and stop reminders can flag a missed timer.
If you still miss one, use sent files, messages, and your calendar as clues. They can help you estimate a session, but do not prove its start and stop. Mark reconstructed time as an estimate.
Where consultant time tracking goes wrong
One trap is treating every engagement like a firm project code.
You don’t need five layers of tasks to explain who the work was for. Start with client and engagement. Add tags for meetings, research, or delivery only when you will actually filter on them later.
The second failure is writing notes only for yourself. “Sync with Sarah” is fine on Tuesday. It names the person, but leaves out the work. Use the client’s words when the line might be shared.
The third failure is buying features you won’t use. Shared approvals, client portals, and utilization dashboards can help when your work calls for them. Without that need, they’re another system to maintain.
If your billing already lives in accounting software or a spreadsheet, your tracker should feed that workflow, not replace it.
The fourth failure is relying on automatic tracking when its activity log doesn’t identify the engagement or task. A window title might name a client document, or it might only say “Untitled” or “Inbox.” When it doesn’t name the client, add that context while you remember it.
What to look for in a consultant time tracker
Can you walk into a client conversation already knowing where the hours went?
- A running total per engagement, so you can compare hours used with the retainer allotment during the month.
- Notes you would be willing to show. If an entry can go into a client summary unedited, the record is doing two jobs at once.
- Edits when the day got messy, so you can fix a timer you forgot during a client call.
- Labels that match how you sold the work. One level for the client, one for the engagement. Try the setup with a short advisory call before you commit to it.
- Offline capture if you work at client sites, on trains, or anywhere a connection can drop.
- A plain CSV export, so the record can go with you when a client or your accountant asks for it.
For this record, focus on hours and work notes. Screenshots and activity scores don’t replace an explanation of what you did for the client.
Where TimeRetain fits
Client names and rates are sensitive. TimeRetain keeps the primary record on your device without an account. Optional Sync stores an encrypted copy on TimeRetain’s servers.
TimeRetain lets you group each client’s work and see each engagement’s total. When a retainer feels stretched, you can see the hours behind it and read what those hours covered.
Bring that record to your next client conversation. Use it to explain what the month covered and whether the next month needs a different scope.
Keep the hours and notes for your next retainer review in TimeRetain. Start with one client. No account required.
Start with one client
For one week, track a single client: engagement, start, stop, and a one-line outcome note. Start when the work starts. Stop when you switch, including to internal work.
Then read it back. Can you explain the hours? Does the retainer still fit? If a note would confuse the client, rewrite it before next week.
Questions and answers
How do you keep track of time as a consultant?
Start a timer when work begins, stop it when you switch away, and add a short note that names the result for the client. Keep unpaid client work with its engagement, but separate it from hours you bill or count toward a retainer allotment. Rename notes the same day, check totals once a week, and do a last pass before you invoice or review a retainer.
What should a consultant time tracking record include?
At minimum: client, engagement, date, start and stop times, and a short note in client language. Mark a reconstructed block as an estimate. Label the type as hourly, retainer, fixed fee, or non-billable, and add the rate when you bill by the hour.
Should consultants track time on retainers?
Yes, if you want to know whether the monthly fee still fits the work. A log lets you make that comparison, even when the invoice has no hourly lines. If the retainer includes an hour allotment, check the total during the month.
Do independent consultants need firm time tracking software?
If you work alone without shared approvals, start with fast entry, easy edits, clear client labels, and a clean export. Add team features only when you need to coordinate records with someone else.
Should consultants track time on fixed-fee projects?
Yes, if you want to compare the fee with the time spent. After the engagement ends, divide the fee by all its hours to get revenue per hour before costs. Compare that figure with your target before you price similar work.
