Best Time Tracking Software for Consultants
Use the free calculator below to find your target billable utilization rate. Consulting runs on hours, whether you bill by the hour, by retainer, or by a fixed-fee engagement priced around an estimated number of hours. The problem isn't usually the billing model, it's that time gets tracked loosely, spread across a notebook, a spreadsheet, and memory, until invoicing day turns into reconstruction work. Below is a free generator that shows what utilization rate you actually need to hit your income goal, along with how the top time tracking tools compare for consultants and what to look for if you're managing multiple clients and engagements at once.

What Consultants Actually Need from Time Tracking Software
Consultants usually bill in more than one way across a single client roster, hourly for some engagements, retainer for others, fixed-fee for a project here and there. The tools that work well are the ones that don't force every engagement into the same billing shape. What matters most is whether tracked time rolls up cleanly by client and engagement, and whether it's visible enough to catch a retainer that's quietly running over its hours before it becomes a loss.
Consultants who don't separate billable from non-billable time tend to overestimate their own utilization, since proposal writing, discovery calls, and account management all eat real hours without generating revenue. Tracking that time, not just the billable portion, is what makes a utilization number trustworthy instead of optimistic.
Methods for Tracking Time as a Consultant
Which method fits depends mostly on how many active engagements you run at once and whether your billing mixes hourly, retainer, and fixed-fee work.
| Method | Works Well When | Breaks Down When |
|---|---|---|
| Manual Log / Notebook | One engagement, very predictable hours | More than one active client or any retainer work |
| Spreadsheet | A handful of clients, comfortable building invoices by hand | Utilization and per-client profitability become hard to see |
| Standalone Timer App | Need accurate hours fast across engagements | Tracked time and invoicing live in separate tools |
| Connected Platform | Multiple clients, mixed billing models, need utilization visibility | Rarely breaks down, but more setup than a bare timer |
For most independent and small-firm consultants, a spreadsheet works until utilization, not just hours billed, becomes something you need to see at a glance. That shift usually happens once a second or third concurrent engagement makes it genuinely hard to know, in the moment, how close any one retainer is to running over.
How We Evaluated These Tools
Full disclosure up front: Updoot publishes this site, and it's included in the comparison below. To keep that honest, every price and feature claim for every tool, including Updoot, was checked against each company's current pricing page or independently verified third-party sources as of June 2026, and we're transparent about where a tool genuinely wins on a given criterion, even when it isn't Updoot.
For consultants specifically, we weighted five things: whether the tool supports retainer billing and not just hourly, whether utilization or profitability reporting is available without jumping to the most expensive tier, how directly tracked time converts to an invoice across mixed billing models, whether per-client and per-engagement budgets are visible in real time, and how pricing actually scales as a practice adds clients or team members.
Retainer and Utilization Tracking: What to Look For
Most general-purpose time trackers are built around hourly billing first, and treat retainers as an afterthought, a flat number you set once and never check against actual hours. That gap matters for consultants more than almost any other audience, since a retainer that's quietly absorbing more hours than it was priced for is one of the easiest ways for a practice to lose money without anyone noticing. Look specifically for whether a tool shows pace or burn-rate against a retainer in real time, not just a monthly total after the fact, and whether profitability or utilization reporting is available without paying for the top tier.
How the Top Time Tracking Tools Compare for Consultants
| Tool | Starting Price | Best For | Where It's Limited for Consultants |
|---|---|---|---|
| Updoot ⭐ Best Overall | $5/user/month | Consultants who want time, invoicing, projects, and customers connected, across hourly and retainer engagements | More setup than a bare-bones timer if all you need is a stopwatch |
| Harvest | Free (1 user, 2 projects); paid from ~$10.80/user/mo, profitability reporting at $14/user/mo | Per-project and per-client budget alerts standard, even on the entry paid tier | Acquired by Bending Spoons in 2025; some users report steep renewal price increases via usage fees, worth checking current terms for a multi-year engagement |
| Toggl Track | Free (5 users); Starter $9/user/mo; Premium $18/user/mo | Fast timers across multiple devices and engagements, billable rates from Starter | Profitability and labor-cost reporting locked to the $18/user/mo Premium tier; no native retainer pace or burn-rate alerts at any tier |
| Clockify | Free (unlimited users); Pro tier ~$10/user/mo | Labor cost and profitability views at a lower price than Toggl Premium | Free tier alone won't support per-client billing or retainer tracking |
| Everhour | Free (5 users, no integrations); Team $8.50/user/mo (5-seat minimum) | Consultants already running engagements inside Asana, ClickUp, or Trello, with budget and estimate-vs-actual data inside the task view | 5-seat minimum is less punishing for a small consulting team than a solo operator, but retainer-specific pace or rollover tracking isn't a native feature |
Editor's Pick
Why Updoot Tops This List for Consultants
Harvest comes closest on budget alerts and invoicing, but its acquisition-related pricing uncertainty is a real consideration for a long-running retainer relationship. Toggl gates profitability reporting behind its most expensive tier, and Clockify and Everhour both require piecing together retainer tracking from general-purpose budget features rather than something built for it. Updoot ties time logged against hourly and retainer engagements alike into the same project budget view, with invoicing and customer history connected by default, at a flat $5/user/month. For a consultant juggling several billing models across several clients, that's the difference that matters most day to day.
The right pick depends on whether your practice runs on one billing model or several, and whether you'd rather track time in one place and build invoices in another, or have the two stay connected by default.
How Updoot Handles Invoicing, Projects, and Customers
Updoot ties every tracked hour to a customer and a project from the moment it's logged, which matters for consultants juggling several clients and engagement types at once. Each customer record holds its own projects, contact details, and billing history, so utilization and revenue by client are visible without pulling data from separate invoices or spreadsheets.
Projects can be set up to match whatever billing model an engagement actually uses, hourly, retainer, or fixed-fee, and each one carries its own budget so a retainer that's tracking over its allotted hours shows up while there's still time to address it with the client, rather than at month's end. Time logged against a project rolls into that project's totals automatically, which is what makes utilization reporting accurate instead of approximate.
Invoicing pulls directly from tracked time: choose a customer, select the engagement or date range, and Updoot builds the invoice from logged hours and rates without anything needing to be re-typed. Hourly time and fixed-fee or retainer amounts can sit on the same invoice, and every invoice stays tied back to its customer record, so payment status and engagement history live in one place instead of scattered across email. The same data feeds Updoot's budgeting and P&L reporting, so a consultant can see profitability by client or engagement type, not just a list of hours, all included in the platform at $5 per user per month.

Frequently Asked Questions
The best option is whichever one matches how you actually bill: by the hour, by retainer, or by a mix of fixed-fee engagements and hourly work. Consultants juggling several clients and engagements at once get the most value from a tool that ties time directly to a client and project, so utilization and billable hours are visible without pulling data from multiple places.
Yes, for two reasons beyond just billing accurately. First, hourly or retainer billing without precise tracking almost always underbills, since reconstructing a week from memory tends to round down. Second, tracked time is what shows whether an engagement type is actually profitable once hours worked are compared against what the client paid.
At minimum: a timer or manual entry tied to a specific client and engagement, support for both hourly and retainer billing, and the ability to turn tracked time into an invoice without re-entering it elsewhere. Beyond that, utilization reporting, engagement-level budgets, and per-client profitability are what separate a basic timer from something built for running a consulting practice.
Utilization rate is billable hours divided by total available working hours in a period, usually shown as a percentage. Consultants track it by logging every hour, billable and non-billable, against the same calendar, then comparing billable hours to total capacity rather than just looking at revenue, which can hide a utilization problem behind a single large engagement.
Yes. Even when a client is billed a flat monthly retainer rather than by the hour, tracking time against that engagement is what tells a consultant whether the retainer is still priced correctly. Retainers that quietly absorb more hours than they were priced for are one of the most common ways consulting engagements become unprofitable without anyone noticing until much later.
By tagging every entry as billable or non-billable at the moment it's logged, tied to the relevant client or marked as internal. Proposal writing, business development calls, and internal admin all add up, and consultants who don't separate that time from billable work tend to overestimate how much of their week is actually generating revenue.
It varies by practice, but a common reference range is 60 to 80 percent for independent consultants once business development, admin, and proposal work are accounted for. A rate that looks healthy on paper but keeps creeping down month over month is usually the first sign that non-billable work is quietly crowding out client hours.
Final Takeaway
The best time tracking software for consultants is the one that keeps utilization, invoicing, and client history connected instead of scattered across separate tools. Use the calculator above to check your utilization target against what you're actually tracking, and if the gap is wide, that's usually a sign your rate, your capacity assumptions, or how you're tracking non-billable time needs a closer look.
