Money you spend on a client’s behalf should not be buried in the price

Two kinds of money inside a single number

A quote usually contains your time, priced at whatever your work is worth, and money you will lay out on the client’s behalf — a journey, a component, a licence, a specialist you engage to do part of it. These are different animals. One is income you have earned; the other is a sum that passes through your account and leaves again.

Presented as a single figure, they become indistinguishable, and the buyer has no way to tell whether they are paying a high price for the work or an ordinary price plus a substantial outlay. That confusion costs the seller more often than it benefits them.

Burying costs distorts the price in both directions

If costs are absorbed into the headline number, your prices look higher than a competitor who separates them, and you will lose comparisons you should have won. If costs are excluded but never mentioned, the eventual invoice exceeds the quote and the client feels misled, which is worse.

The second failure also poisons legitimate charges. A client surprised once by an unexpected line will scrutinise every subsequent one, and the argument about a modest journey costs far more in time and goodwill than the journey ever did.

Decide what belongs inside the price

The usual line is between things consumed by running your business and things bought for a particular job. The tools, the software, the insurance, the accountant, the vehicle and the general consumables are yours; they should be inside your rate, because they exist whether or not this client called.

Materials specific to this job, travel undertaken solely for it, and anything you buy at the client’s direction sit on the other side of the line. There are grey areas — a short local journey is usually absorbed, a day-long one usually is not — and the resolution is to state your convention rather than to find a universal rule. Convention plus disclosure beats accuracy plus silence.

Agree the mechanism before you spend anything

The quote should say which costs are extra, how they will be charged, and whether anything is added on top. It should also set a limit above which you will ask first. That threshold is the single most useful sentence in this part of a quote, because it converts every future surprise into a decision the client already made.

Whether to add a handling margin to third-party costs is a matter of practice and honesty rather than of rules. Some trades do it openly and it is understood as covering the work of sourcing and carrying the cost. What causes trouble is doing it quietly, because a client who discovers a hidden margin on a receipt they can see stops trusting the figures they cannot.

Until you are reimbursed, you are lending

Money spent on a client’s behalf leaves your account immediately and comes back whenever they pay. For a small business a significant purchase made for somebody else’s job is a real drain, and it is one of the quiet ways a busy period produces an empty account.

The remedies are ordinary. Substantial costs can be invoiced when incurred rather than at the end. Suppliers can bill the client directly for large items. Or a deposit can cover the outlay before it happens. All of these are normal practice and none of them require a difficult conversation, provided they are proposed at the quoting stage.

The exposure is worth watching in aggregate rather than job by job. Four modest purchases across four clients can add up to more than the business has spare, and because each one felt small at the time nobody noticed the total. If the answer to how much of your own money is currently sitting in other people’s projects is that you do not know, that is the number to find.

Keep the evidence, and ask how it should be treated

Rebilled costs need documentation: what was bought, for which job, and the receipt to prove it. That is partly for the client, who may reasonably want to see it, and partly because these amounts appear in your own records as both money out and money in.

How that is handled — whether such amounts count as your income, how they interact with any sales tax, what evidence is required — genuinely differs between countries and structures, and getting it wrong is easier than it sounds. It is a short question for a qualified accountant, and worth asking once rather than guessing every year.
