Time Tracking Software for Agencies: The 7 Requirements That Matter

Time tracking software comes in dozens of flavors, but an agency is not a construction company and not a solo freelancer. At an agency, multiple people work across multiple clients at once, retainers and projects run side by side, and every unlogged hour is a direct hit to the margin. These are the seven requirements that truly matter for agencies.

1. Hours per client, project and service

An agency rarely bills "just hours." There are retainers with a monthly budget, fixed-price projects and one-off time-and-materials jobs — often for the same client. Good software lets team members log hours against the right project and the right service within it, so every time entry automatically carries the correct billing method and rate. Without that structure, month-end close becomes a puzzle.

2. An approval workflow that protects the invoice

At agencies, logged hours end up on client invoices. One day booked to the wrong place can damage a client relationship or cost you a credit note. An approval workflow — a project lead approves hours before they become billable — is therefore not bureaucracy but quality control on your revenue.

3. Billable utilization visible per person

The core metric of every agency: what share of contracted hours is logged as billable? Software that shows this per person and per week turns the capacity conversation into a factual one instead of a gut-feel one. Industry rule of thumb: billable utilization structurally below 60% means something is off in planning, sales or logging discipline — and you want to know which of the three.

4. Retainer burn in real time

Clients on a prepaid-hours bundle or monthly budget (rightly) want to know where they stand. An agency wants to know even sooner: a retainer that's burned through by week two is worth a conversation — this month, not at the quarterly review. Choose software that tracks consumption per retainer live against the monthly budget. See how that works on our features page.

5. Logging in seconds, even on Friday afternoon

The best time tracking is the kind your team actually uses. A timesheet where a few keystrokes add a line, mobile entry from the client's office, and automatic reminders for stragglers — that difference determines whether your hours are accurate on Thursday or only (partly) on Monday. For more general selection criteria, see our article on choosing time tracking software.

6. From approved hours to draft invoice — automatically

The payoff of good time tracking sits at the end of the chain: approved hours staged as draft invoice lines without retyping, grouped per client and project, at the right rate. Agencies that automate this step do their monthly invoicing in an hour instead of a day — and demonstrably invoice more, because nothing gets "forgotten" along the way. See how time tracking and invoicing connect in Horixa.

7. Open data: API and export

Your time data is strategic information. A full-featured REST API enables custom dashboards, BI-tool integrations and automations — and prevents you from being locked into a product three years from now because your data can't leave. Ask every vendor: can I retrieve everything I enter back through the API?

Frequently asked questions

What does time tracking software cost for an agency? Standalone time tracking tools start around €5–10 per user per month, but agencies usually need an integrated suite (time + projects + invoicing). Those typically run €20–30 per user per month. Horixa starts at €19.95 per user per month.

Isn't a standalone time tracking tool enough? For a freelancer, yes. For an agency, the value comes precisely from the chain: hours → approval → budget tracking → invoice. A standalone tool just relocates the retyping.

How do I get my team to actually log their hours? Lower the friction (weekly timesheet, mobile), make it visible (weekly reminder when someone falls behind) and visibly use the data in decisions — people who see that the hours matter will log them.
