Time Tracking for Agencies: Keep Every Project Profitable
· 5 min read
For a small agency, time is the inventory. Every hour a designer, developer, or strategist spends on a client either gets billed, gets absorbed into a fixed fee, or quietly disappears. Good agency time tracking is how you tell those three apart. It shows which clients are worth keeping, which projects ran over, and whether your rates actually cover the work. This guide covers a simple, repeatable setup that works for agencies of two to ten people without turning everyone into a timesheet clerk.
Why agency time tracking is different from freelance tracking
A solo freelancer usually knows roughly where their week went. An agency doesn't. Work is spread across several people, several clients, and several projects per client, and the person sending the invoice is often not the person who did the work.
That creates a few specific problems:
- Hours leak between handoffs. A developer spends 40 minutes fixing a bug the account manager never hears about, so it never gets billed.
- Rates vary. A retainer client might have a discounted rate while a one-off project gets your standard rate.
- Clients ask for proof. Larger clients often want to see what they are paying for, line by line.
A tracking setup for agencies needs to handle all three: capture every hour, apply the right rate, and produce a report the client can read.
Structure your work as clients and projects
Before anyone starts a timer, decide how work is organized. A structure that holds up well:
| Level | Example | What it's for |
|---|---|---|
| Client | Acme Outdoor Co. | Who gets the invoice |
| Project | Spring campaign landing pages | What the work is for; one invoice line |
| Time entry | "Hero section revisions, round 2" | What was actually done |
Keep project names meaningful to the client, not just to your team. "Spring campaign landing pages" is clearer on an invoice than "ACME-Q2-LP". Since invoices in ClockPaid put one line per project, the project name is literally what the client reads.
Write entry descriptions the same way. "Meeting" tells nobody anything; "Kickoff call re: product page copy" does. For more on this, see our guide to timesheet best practices for consultants.
Set rates at the right level
Agencies rarely charge one rate for everything. A layered approach keeps it manageable:
- Default rate — your standard hourly rate, used when nothing else applies. Say $120/hour.
- Client rate — overrides the default for a specific client, for example a long-term retainer client at $100/hour.
- Project rate — overrides both for a specific project, like a rush job at $150/hour.
Setting the rate once at the right level means nobody has to remember it when logging time. If you're not sure your default rate covers overhead, salaries, and downtime, work through how to calculate your freelance hourly rate; the same math applies to agency blended rates.
Separate billable and non-billable time
Not every hour gets billed, but every hour is worth tracking. Internal meetings, pitches, and fixing your own mistakes are real costs even if the client never pays for them.
Flag each entry as billable or non-billable rather than skipping the non-billable ones. Over a month, the ratio tells you a lot. If a client generates 60 billable hours and 25 non-billable ones, that account is far less profitable than the invoice suggests. Our article on billable vs non-billable hours goes deeper on what belongs in each bucket.
Make logging time painless
The best tracking system is the one people actually use. A few habits help:
- Use a live timer for focused work. Start it when you open the file, stop it when you switch tasks.
- Use manual entries for everything else. Calls taken on the go, quick fixes, and work you forgot to time can be added after the fact.
- Log daily, not weekly. Friday-afternoon reconstruction of a whole week is where hours get lost.
- Keep a phone option. Someone at a client site or on a call can log time from an Android phone instead of waiting until they're back at a desk.
Turn tracked time into client reports and invoices
At the end of a billing cycle, the payoff arrives. Pull a per-client time report for the period — this month, last month, the last two weeks, or a custom range — and review it before billing. Look for:
- Entries with vague descriptions that need tidying
- Time accidentally marked billable (or non-billable)
- Projects that ran well past their estimate
Then generate the invoice from the client's unbilled billable time in that period. Each project becomes a line, the rate is applied automatically, and a PDF of every underlying entry is attached so the client can see exactly what they're paying for. Because billed time is tied to that invoice, the same hours can't end up on a second one by accident.
Review profitability monthly
Once a month, look back at each client:
- Total billable vs non-billable hours
- Effective hourly rate (invoice total divided by all hours worked, billable or not)
- Projects that consistently overrun
If a client's effective rate is well below your default, that's a conversation to have: raise the rate, tighten scope, or move them to a different pricing model.
FAQ
How detailed should agency time entries be?
Detailed enough that the client understands the work without asking. One short sentence per entry is usually right. Avoid internal jargon and ticket numbers without context.
Should we track time on fixed-fee projects?
Yes. Even if you don't bill hourly, tracked time shows whether the fixed fee was priced correctly. Mark those entries non-billable, or keep them on a separate project, so they don't end up on an hourly invoice.
How often should an agency invoice?
Most agencies bill monthly or every two weeks. Shorter cycles improve cash flow; longer cycles reduce admin. Pick one per client and stick with it.
Getting started
Agency time tracking doesn't have to be elaborate. Clients, projects, the right rates, and a daily logging habit cover most of it; the rest is reviewing reports before you bill. ClockPaid was built around exactly that flow, from timer to per-client report to invoice with the timesheet attached. If you want to try it with a couple of clients, you can start free.
