There are fifty-odd articles on this site about how to make money online. Keyword research, email lists, funnels, affiliate offers, the lot.
There are none about what to do with the money once it turns up.
That’s a strange gap, and it’s mine, so I’m filling it. Because the first time your site pays you properly is a genuinely good day, and it’s also the day you start making decisions you’ll either be glad about or quietly annoyed about in ten years.
None of what follows is complicated. Most of it is dull. That’s rather the point.
First, the money is not yours yet
This is the one that catches people out, and it catches them out badly.
Money that lands in your account from an affiliate network is not income. It’s revenue. Some of it belongs to the taxman, and he will want it, and he is not interested in the fact that you spent it on a laptop.
If you’re used to being employed, this feels wrong. Employment hides all of this from you — the tax comes out before you ever see the money, and what hits your account is genuinely yours. Working for yourself removes that entirely, and nobody replaces it.
So replace it yourself. Open a second account, work out roughly what proportion of your earnings you’ll owe, and move that across the moment the money arrives. Not at the end of the month. Not when you get round to it.
I’d rather over-reserve and get a pleasant surprise than under-reserve and get an unpleasant one.
If your income is genuinely unpredictable — and affiliate income usually is — reserve on the high side. The worst outcome of over-reserving is that you find some money you’d forgotten about.
Second, the boring buffer
Once the tax money is out of the way, the next chunk doesn’t get invested and doesn’t get spent. It sits in cash, in an ordinary savings account, doing very little.
The reason is not caution for its own sake. It’s that online income is lumpy. A commission structure changes, an affiliate programme shuts, Google reshuffles a page you’d been relying on, and a good month becomes a bad quarter with no warning.
A buffer means that when it happens, it’s an irritation rather than an emergency. It’s the difference between rebuilding a page properly and taking the first bad decision that pays you this week.
How big? Enough months of your actual living costs that a bad quarter doesn’t reach you. Only you know what that number is.
The buffer is the thing that lets you keep making good decisions when the income stops behaving. That’s what you’re buying with it. Not interest.
Third — and only third — the rest
Now we get to the part nobody covers.
If the site keeps working, eventually there’s money left over after tax and after the buffer. And this is where most people who earn well online quietly go wrong, because they do one of two things.
They spend it. Which is fine, up to a point, and I’d never tell anyone not to enjoy the thing they worked for.
Or they leave it sitting in the business account. Which feels responsible, and isn’t. Cash that sits still loses value every year — slowly, invisibly, and without ever showing you a loss on a statement. Inflation doesn’t send you a notification.
The alternative is to put the surplus somewhere it grows. Not somewhere clever. Not something that requires you to have opinions about interest rates.
This is where I’ll be straight with you about a conflict: I write a separate newsletter about exactly this, so I’m hardly neutral. It’s for UK investors and it’s a completely different animal to this site. But if you want to see how I invest my own money, including what I actually hold and what it’s returned, that’s the free starting point and it’s about as unglamorous as it sounds.
That’s investing content, not personal financial advice — it’s what I do, not a recommendation of what you should do.
Why this matters more for us than for most
There’s a specific reason this applies more sharply to people building an online income than to people with jobs.
An employee’s finances have guard rails built in by other people. Tax is deducted. In the UK, a pension is usually started for you whether you asked for one or not. The system quietly does a passable job in the background.
Work for yourself and every one of those guard rails disappears at once, and nobody tells you. There’s no letter. You just stop being enrolled in anything.
Nobody is going to do this for you, and nobody is going to mention that nobody is doing it for you.
So the honest summary is: the money your site earns is only half the job. Where it goes afterwards decides whether you built an income or built some wealth. They’re not the same thing, and the second one takes longer and is much quieter.
