Same rate for four years and I am afraid to change it — how do you raise prices on clients you already have?

I did this after five years at the same rate and the outcome was so undramatic it was almost disappointing. Nobody left.

What I sent was three lines: my rate is going up to X from the first of April, this covers work booked after that date, happy to talk if it causes a problem. No justification, no apology, no explanation of my costs.

Leaving out the justification is the important part. An explanation invites a negotiation about whether the reason is good enough, and it frames the increase as something you are asking permission for. A supplier informing you of a price is normal and nobody argues with it; a supplier explaining that things have got expensive sounds like an opening bid.

The mechanics that worked:

Notice. A month or two, and give a specific date. Enough that nobody is surprised, not so much that it gets forgotten.

Honour what is already agreed. Anything quoted or booked stays at the old rate. This removes the only genuinely reasonable objection.

Everyone at once. Same date, same email, adjusted amounts. Staggering it means you have this feeling six times instead of once, and it makes the rate look negotiable.

Send it and stop thinking about it. The replies were, in order: fine, fine, no reply at all, fine, one asking to keep the old rate until a project finished, which I agreed to.

On the fear about your two big clients — worth separating what you are actually afraid of, because it is usually not the rate.

In my experience the clients who leave over a reasonable increase are the ones who were already close to leaving, and price was the excuse rather than the reason. The ones who value the work absorb it without much comment, because the cost of replacing you is much higher than the increase. That asymmetry is the thing to hold on to: a new supplier costs them briefing time, mistakes, and risk. A ten or fifteen percent increase does not come close.

That is also why your position is stronger than it feels. Being busier than you want to be is not a coincidence alongside an unchanged rate for four years — it is the direct consequence, and it means you are currently the cheapest way for those clients to get this done. Cheap suppliers who are always busy are not in a weak negotiating position, they are in a strong one they have not noticed.

The honest risk is concentration, not price. Two clients being most of your income is the actual problem in your message, and it will be true at any rate. If one of them does leave, the increase did not cause that exposure, it revealed it.

Which argues for doing it now rather than later, while you are busy and have leverage, rather than after a quiet quarter when you feel you cannot afford to.

The lower-risk version, if the direct one feels like too much for the two big ones: raise the rate for new clients immediately and let the existing ones follow at a natural boundary.

A natural boundary is the start of a new project, a contract renewal, a new financial year, or a change in scope. At that point the conversation is not I am putting my prices up, it is here is the quote for this piece of work — which is a completely ordinary sentence.

What this gets you:

• A rate you can say out loud without flinching, which matters because you will be quoting it to strangers within a week
• Evidence. Once two new clients have accepted the higher rate, telling the older ones is much easier, because you now know the number is real rather than hoped for
• Time to build the pipeline you said you do not have

The cost is that it is slower, and there is a trap: the gap between what new clients pay and what your oldest and best clients pay grows quietly until it is embarrassing, and the longer it goes on the harder that conversation gets. So set yourself a date — you will bring everyone onto the new rate by such-and-such — rather than letting it drift.

The common ending to the drift version is realising you are charging your two most important clients the least of anybody, which is roughly where you are now after four years.
