Half of a self-employed week is not billable, and the rate has to know it

The hours that disappear

Keep an honest record of a working week and the result is uncomfortable. A substantial share of it goes to activity that no client will ever be invoiced for: answering enquiries, writing quotes, negotiating, invoicing, chasing payment, keeping records, dealing with suppliers, updating whatever you use to be found, and learning the things the work requires you to know.

This time is not slack. It is production overhead, in the same sense that a factory floor is not the whole factory, and treating it as a personal failure of efficiency leads to exactly the wrong conclusion.

Where the proportion actually goes

The share varies by trade and by how the work arrives. A business with a handful of long engagements spends less of its week selling than one that runs many small jobs, because each job carries its own quote, its own setup and its own invoice regardless of size.

That’s the mechanism behind something most people notice without explaining: small jobs are less profitable than their price suggests. The non-billable tail is roughly constant per job, so a job worth a fraction of another carries very nearly the same overhead. Below a certain size, the overhead eats the entire margin.

Which is a case for a minimum charge rather than for refusing small work outright. A minimum makes the fixed cost of a job visible in the price, and it does so without requiring you to explain yourself.

The rate has to carry the whole week

If a meaningful share of your available hours cannot be invoiced, then the hours that can be invoiced have to fund all of them. That’s not a pricing philosophy, it is division, and it is the reason a rate can’t be derived from what you would like to earn per hour of work.

The arithmetic is worth doing in your own numbers rather than in general terms. Take what the business must produce in a year, divide it by the hours you can realistically sell rather than the hours you will work, and the result is the floor for your rate. It is usually higher than the figure people carry in their heads.

The tax position sits on top of this and differs by country and structure, so the amount that ends up with you is a question for an accountant. The principle is unaffected: the divisor is billable hours, not working hours.

Measure before you try to fix anything

Most people estimate their own billable proportion badly, and almost always in the same direction. The remedy is to track time for a period — several weeks, not several days, since the balance shifts depending on where the jobs are in their cycle — including the time spent on the tracking.

What that exercise usually reveals is one or two activities consuming much more of the week than anybody expected. Frequently it is quoting for work that was never won, or the repeated re-explanation of things that could have been written down once.

Some of it can be reduced, and some of it cannot

The reducible part is repetition. Anything you have written from scratch more than three times is a candidate for a template, and templates for quotes, contracts, onboarding and handover recover more hours than any productivity method.

Better qualification of enquiries reduces the quoting that leads nowhere, which is often the largest single item. And the administrative sediment shrinks considerably once the record-keeping is done as you go rather than reconstructed at the end of a period.

What can’t be reduced is the irreducible minimum of running a business: the selling, the record-keeping, the obligations. Those hours exist for as long as the business does. Pretending they can be eliminated leads to a rate set on a fantasy, and the shortfall shows up as a year that was busy and somehow produced very little.

Why this matters more for one person than for a firm

A larger organisation separates these functions between people, so the person doing the work is doing the work while somebody else quotes and invoices. The overhead still exists and it is still priced in — it is simply less visible.

On your own, you are all of those people in sequence, and the switching between them has its own cost. That is an argument for batching the administrative work into defined blocks rather than letting it interleave with delivery, and it is one of the few pieces of scheduling advice that survives contact with an actual week.
