TL;DR: Agencies do not have a time tracking problem, they have a proof and utilisation problem. Pick the tool that makes billable evidence easy to produce and tracking easy to do — adoption beats features every time.
Generic time trackers record hours. Agencies need something narrower and harder: proof of what was delivered against a client budget, utilisation per person, and profitability per account. This guide covers what separates agency-grade tracking from a timesheet, and how to get a team to actually use it.
A retainer with no burn-down is a scope-creep invoice waiting to happen. The tool must show hours consumed against the agreed budget in real time, and warn before you cross it rather than after the month closes.
Billable hours divided by available hours, per person, per week. Without it you cannot tell whether you need to hire, whether someone is drowning, or which accounts quietly lose money. Any tool that cannot produce this report is a timesheet, not an agency tool.
The most sophisticated tracker is worthless if half the team fills it in on Friday from memory. Favour whatever makes starting a timer nearly free — a browser extension, an integration inside the tool people already work in, or automatic capture — over a longer feature list.
The moment a client questions an invoice, you want to send a clean record of what was done, when and by whom, without reformatting anything. Check what the export looks like before you buy, not after the dispute.
Client activity ledger for agencies. Track hours, deliverables, and prove your work.
The one your team will actually use. Beyond that, prioritise budget burn-down, utilisation reporting and client-ready exports — those three separate agency tools from generic timesheets.
Billable hours divided by total available hours for the period, per person. Most agencies target 70-80% for delivery staff; consistently above that usually signals an overload rather than efficiency.
Flat rate, if the option exists. Per-seat pricing discourages tracking for contractors and part-timers, which is exactly where untracked billable hours go missing.
