Time tracking software for consultants: what a solo practice actually needs
Most tools in this category were built for agencies and sold to individuals. Here is the shorter list of things that change what you get paid.
A solo consultant needs four things from time tracking software: a timer tied to a client with a rate, entries you can correct after the fact, a running view of what is unbilled, and an invoice that itemises the hours without retyping them. Task boards, team seats and client portals do not affect what you get paid.
The real failure isn’t tracking, it’s reconstruction
Nobody loses money because they lack a stopwatch. They lose it on the last day of the month, sitting in front of a blank invoice, working backwards through a calendar to guess how long Tuesday’s call ran. Calendar entries record intent, not duration. The forty minutes of prep before the call and the twenty minutes of notes after it leave no trace at all.
So you round. Almost always down, because you would rather absorb an hour than defend one. Rounding in the other direction has its own trap, which is the subject of billing in six-minute increments. Do that across four clients for a year and the invisible discount is larger than any tool’s subscription by an order of magnitude.
Underbilling is not a discipline problem. It is a memory problem, and memory is the wrong tool for the job.
Four requirements, and why the rest is noise
Judge any tool in this category against these. Anything that fails one of them will be abandoned by week three, whatever else it does.
A timer that already knows the client and the rate
If starting requires choosing a project, a task and a billing category, you will not start it. One choice, which client, and the money counts itself.
Entries you can add and correct afterwards
You will forget to start it, and you will leave it running overnight. A tool that treats the timer as the only valid input is a tool you will quietly stop trusting.
A live view of what is unbilled
Not a report you generate. A number you glance at, so the size of an unpaid month is never a surprise on the 30th.
An invoice generated from the entries, not retyped
This is the whole game. The moment a human copies hours from one screen into another, the copying gets postponed and the detail gets rounded away.
Why the category keeps selling you agency software
Per-seat pricing rewards vendors for building features that only make sense with several people in the account. Approval flows, capacity planning, role permissions and client portals all exist to move information between humans who cannot simply turn around and ask each other. Working alone, you are both ends of every handoff, so those features become forms you fill in for an audience of one.
The cost is not the money. It is that a tool with forty surfaces asks you to make forty small decisions before it will accept an hour of work, and on a busy Thursday you will decline. The tracker with the fewest steps between I started and it’s recorded is the one that stays in use.

What to do about it this month
Pick one client and time every interaction with them for four weeks: calls, prep, notes, the email that took twenty-five minutes to word. At month end, compare the total against what you would have invoiced from memory. The difference is your answer, and it is usually uncomfortable.
Then remove the step that makes tracking fail: the retyping. You can see what that looks like end to end in the demo, with no account and a real PDF at the end of it. If the hours you recorded do not become the lines on the invoice by themselves, you have built a second job for yourself on the 30th, and second jobs get skipped.
HourToBill does the four things and stops.
A timer against a client, entries you can fix, a month view of what's unbilled, and a PDF invoice with every hour itemised. One plan, $12 a month.
