Time tracking software for billable hours and what gets written off

Time tracking software for billable hours has an unusually precise job. It is not there to show how hard everyone worked. It is there to establish, defensibly, which hours may be charged to whom, at what rate, and which ones will quietly be absorbed.

The decision belongs at the moment of entry

Whether an hour is billable is a judgement, and it is at its most accurate immediately. A fortnight later it becomes a negotiation between somebody’s memory and the shape of the invoice they would like to send.

Time tracking software for billable hours should therefore make that choice cheap and immediate, a single field at the point of entry rather than a review exercise at the end of a period.

Marking it as the hour is booked keeps the distinction meaningful. It also means the non-billable total is real, which is what makes utilisation worth calculating at all rather than a number everyone privately discounts.

Write-offs are information

Every practice writes hours off. The problem is not the writing off; it is that it usually happens invisibly, at invoicing, and leaves no trace of which work generated it.

A write-off recorded as a smaller number simply replaces the evidence with the conclusion. The hours that were actually worked disappear, and with them any chance of finding out why the job needed them.

When the original hours remain and the reduction is recorded against them, a pattern emerges after a couple of months: one client, one kind of work, or one stage of a process producing most of it. That is actionable in a way that a monthly margin figure is not.

• billable or not, decided as the hour is booked
• rates by person, by kind of work or by client
• an hours budget per job, consumed as time is logged
• the original hours kept when an amount is reduced
• approval before anything reaches an invoice

From approved hours to a document

The distance between a closed period and a sent invoice is where a surprising amount of revenue evaporates, mostly through retyping. Invoicing works from the approved hours themselves, so what was recorded is what is charged.

Because arrangements differ – hourly, fixed price, a bundle of hours drawn down over months – invoice scenarios hold each client’s terms, and the right document follows from the same set of hours without anyone reopening the contract.

Utilisation without theatre

Utilisation is a useful figure and an easy one to corrupt. Measured as a target it becomes something people manage rather than something people report, and the number stops meaning anything within a quarter.

The honest use of it is diagnostic rather than managerial. Nobody should be asked to raise their utilisation; the figure is there to show where the week is going. Read as a distribution, it is genuinely informative: which work is chargeable, how much of the week goes to things nobody quoted for, and whether that proportion is drifting. Budget monitoring answers the related question per job, while there is still room to act on it.

Getting the rates right once

Most disputes about billable hours are really disputes about conventions: rounding, travel, whether a short call is charged. Setting those in the system once means the same rule applies for everyone, visibly, in the report and on the invoice.

That removes a whole category of argument before it starts. The product matrix shows which version carries invoicing and approval, which is where most practices find the line between what they need and what they do not.
