Billable Hours: What They Are and How to Track Them
By Invoiceabill Team
Billable hours are the hours you work on client work that you can charge for on an invoice. Everything else, like editing your portfolio, chasing late payments, or doing your own bookkeeping, is non-billable. This guide walks through the difference, how to set a rate and hit an annual target, and how to turn a month of tracked time into an invoice, with a worked example and an Excel template you can copy.
Key takeawaysBillable hours are the hours a client pays for; everything else, like portfolio work and chasing late payments, is non-billable and lowers your effective rate.
A full-time year is 2,080 hours. Plan on billing 1,100 to 1,400 of them, and set your hourly rate backwards from your income target.
Log time daily by client and project, either with a timer or a five-minute end-of-day reconstruction, and never batch it to month-end.
Turn tracked hours into an invoice with four steps: sum hours per client, multiply by rate, add flat fees or expenses, and add payment terms.
State your policy on travel time and client calls in the estimate upfront so disputed hours never become an argument.

What does billable hours mean in plain terms?Billable hours are the hours you spend on work a client pays for: shooting, editing, designing, revising, and the calls directly tied to that project. If you bill by the hour and invoice monthly, your invoice is just your billable hours multiplied by your rate. Everything else is non-billable: your own marketing, bookkeeping, chasing an unpaid invoice, scrolling for gear you won't buy. Most freelancers can only bill a fraction of their working hours. The conventional full-time year is 2,080 hours (40 hours × 52 weeks). A solo freelancer bills far less of that. Invoiceabill, the freelancer operating system, tracks billable hours by client and project and turns them into an invoice in the same workspace. That's the core of our Invoiceabill Vs Wave comparison.
Billable vs non-billable hours: what counts as each?A billable hour is time you can charge to a client. A non-billable hour is time you spend on the business that no single client pays for. If you bill hourly, the split determines your income, so knowing where each hour lands matters.

Some items sit in between. Travel, revisions, and admin for a specific client can be billable if you say so upfront; make your policy explicit in the estimate so nothing becomes an argument later. When a client asks what a rate covers, your invoicing should show the line items clearly (https://invoiceabill.com/features/invoicing/).
Why tracking non-billable time still mattersNon-billable hours tell you your real effective rate. If you bill 20 hours at $75 but spend 15 unpaid hours on edits, pitches, and chasing late payments, you earned $43 an hour, not $75. Track both kinds for a month and the gap is usually uncomfortable, which is exactly why it's worth seeing.
How do billable hours work in consulting engagements?In consulting, you bill tracked hours against an agreed scope, usually monthly. Most solo consultants bill well under their working hours, since proposals, admin, and sales eat the rest. Retainers flip the model: the client pays a fixed monthly amount for a set block of hours, and you report what was used.
Billing increments: rounding to 6 or 15 minutesPick a minimum billing increment and round up to it. Legal billing set the convention at a tenth or a quarter of an hour, so 6 minutes (0.1 hours) or 15 minutes. A 12-minute client call bills as 0.2 or 0.25 hours. A write-down is the opposite move: you tracked 3 hours but bill 2 because the client would balk at the full figure. If you run retainers, keep the hour bank where the time lives. Invoiceabill logs usage against each retainer period, flags overages, and rolls unused hours forward, so the drawdown is on record before the client asks.

How to calculate billable hours (with a worked example)The math is three steps: hours × rate = invoice total, then invoice total ÷ hours worked = your effective hourly rate. Keep both numbers in view, because they drift apart fast.
Say you bill $75/hour and log 6.5 hours for a client's video edit in June. The invoice line is 6.5 × $75 = $487.50. If June also held 12 hours of editing your portfolio, chasing late payments, and sorting files, your effective rate across all 18.5 hours worked is $487.50 ÷ 18.5 = $26.35/hour. That gap is the real cost of non-billable time.
Setting your rate backwards from your income targetWork it in reverse. Want $60,000 a year? Divide by your realistic billable hours (most solo freelancers can't bill a full 40-hour week), say 1,200, and you need $50/hour before taxes and expenses. Add your costs and tax buffer on top.
Track billable and non-billable time separately by client and project so you can see the drift monthly, not yearly. A tool built for this workflow, like Invoiceabill, keeps the timer and the invoice in the same place so the math stays honest.
How many billable hours are in a year, realistically?A full-time year is 2,080 hours (52 weeks × 40 hours), but almost none of that is billable for a solo freelancer. Subtract vacations and sick days, then the work that pays nothing: editing your portfolio, chasing late payments, answering emails, and driving to shoots. Plan on 1,100 to 1,400 billable hours, and budget closer to 1,000 for your first full year.
That gap is why your hourly rate matters more than your timesheet. FreshBooks lists its Lite plan at $23/month regular price on its current pricing page, behind a short promotional discount. Check what you actually need before paying for the rest.
How to keep a timesheet for billable hours without losing time?The timesheet is only as good as your habit of filling it. Two approaches work for solo creatives, and one of them loses you money.
Timer vs. end-of-day reconstructionA timer runs while you edit, shoot, or design, and logs each block against a client and project as you go. It is the most accurate method because you never rely on memory. The cost is friction: you have to remember to start and stop it, and forgotten timers mean unbilled minutes.
End-of-day reconstruction means sitting down for five minutes each evening and writing down what you worked on, per client. It is less precise than a timer, usually off by 10-15 minutes here and there, but it never breaks your focus mid-task and it catches everything if you are honest with yourself.
Whichever you pick, the rule is the same: log by client and project, every working day, and never batch it to month-end. Reconstructing four weeks of billable hours from memory is where freelancers quietly underbill themselves, and it is also why monthly invoicing feels like a scramble. A daily five-minute habit turns the invoice into arithmetic instead of archaeology.
How to turn tracked billable hours into an invoice (with an Excel template)Converting a month of tracked hours into an invoice is four arithmetic steps: sum hours per client and project, multiply by that client's rate, add any flat-fee or expense lines, and put the totals on an invoice with your payment terms and due date. If you bill monthly like most hourly freelancers, a single spreadsheet can carry the whole month. The structure below works whether your timesheet lives in the same file or in a timer app you export from.

Add your invoice number, issue date, and "due in 30 days" terms at the top, and a total that sums the Amount column. Save each month as its own file so your accountant can grab a clean record per period.
When a spreadsheet stops being enoughA spreadsheet handles the math, but it can't chase the invoice. Late payment is the failure point: you send the file, the client sits on it, and you're refreshing your bank account instead of shooting. Tools that combine time tracking and invoicing close that loop, and even invoicing-only tools can do the chasing for you. Wave's free plan sends invoices, and its Pro plan adds automated late-payment reminders; check Wave's current pricing for what each tier includes now. The tradeoff: a spreadsheet is free and exactly yours, but you're the one who has to notice an unpaid invoice and send the follow-up email. If you'd rather the software nudge the client, that's the line where copying last month's file stops being the cheap option.
Which tools handle billable hours without overkill?Judge every option on the same four things: does it track time by client/project, turn that time into an invoice, cost less than one billable hour a month, and take minutes to learn.
A spreadsheet does all four for free, but you retype numbers every month. Timer apps like Clockify and Toggl track hours well. Clockify's invoicing needs a paid plan, and Toggl's free invoices carry Toggl's logo until you pay, so you're back to stitching tools together or paying for the second half. Wave is free and sends invoices, but time tracking isn't its core. FreshBooks covers tracking and invoicing, at a higher price than you need if you only bill hourly.
Invoiceabill runs the Floating Timer, clients, projects, and invoicing in one workspace built for freelancers, and it's priced like it. Where it falls short: no accountant-facing full bookkeeping, so your CPA still works from exports, and if you need payroll or double-entry accounting you'll want a dedicated tool anyway. If your month is timers, invoices, and chasing late payments, that trade is usually fine. See https://invoiceabill.com/features/time-tracking/
FAQShould I bill travel time and client calls as billable hours?Yes, if you say so upfront. Travel to a client's location and calls directly tied to the project can both be billable, but only if your estimate states the policy before work starts. Calls the client requests for revisions are easier to bill than your own pitch meetings. Put it in writing so nothing becomes an argument later.
What utilization rate should a solo freelancer aim for?Plan on roughly 1,100 to 1,400 billable hours out of a 2,080-hour year, which puts utilization between 53% and 67%. Budget closer to 1,000 for your first full year.
Do I charge sales tax or VAT on billable hours?It depends on where you and your client sit. Some US states tax professional services, others do not, and VAT rules for freelancers vary by country and registration threshold. Check your state's revenue department or your national tax authority before your first invoice, then add the tax as a separate line so the client sees the split.
How do I handle a client who disputes hours on my invoice?Your timesheet is your defense. If you logged hours daily by client and project, you can send the dated task list for the disputed period and resolve it in one email. If you reconstructed the month from memory, you have little to show. Offer a write-down for borderline items rather than a full refund, then tighten your logging habit going forward.
