Raising Rates With Existing Clients
Existing clients pay historic rates because nothing forces a review, so the increase is a scheduling and communication problem rather than a negotiation about value.

Rates for new clients drift upward with demand while existing clients continue paying what they agreed. The gap widens quietly because nothing in the arrangement triggers a review.
Why the gap opens at all
A new client is quoted the current rate because the quote happens now. An existing client is charged the rate from whenever the relationship began.
Ongoing work rarely has a renewal date, so there is no moment at which the price is naturally reconsidered by either side.
Over several years this produces the position where the longest-standing and most reliable clients pay least, which is the opposite of what the relationship is worth.
The asymmetry that makes it difficult
Raising a rate risks a relationship that already works, while leaving it produces a loss that is invisible because it never appears as an event.
The client's alternative is also worse than it looks. Replacing a supplier who knows their systems and preferences carries a switching cost they rarely calculate explicitly.
That switching cost is the substance of the position, and it usually exceeds the increase being proposed by a considerable margin.
Scheduling removes the confrontation
An annual review date, stated at the outset, converts the increase from an event into a process. The conversation becomes expected rather than initiated.
Notice matters as much as the amount, since a client with a budget cycle can absorb an increase they knew about and cannot absorb one that arrives mid-period.
Applying it to new work while honouring committed work is the usual compromise, and it separates the increase from any project currently under way.
What the message should contain
A statement of the new rate, the date it applies from and the notice given is sufficient. Extended justification invites negotiation of the justification rather than the rate.
Where the scope has grown since the original agreement, describing that growth is relevant, because it explains that the work being priced is not the work originally quoted.
Apologising for the increase frames it as an imposition, which is the framing least likely to produce agreement.
When a client declines
Some will refuse, and the decision is then whether the work at the old rate still earns its place against the capacity it consumes.
Reducing scope to match the old price is a legitimate alternative, and it keeps the relationship while restoring the relationship between price and work.
Losing a client at the bottom of the rate range frees capacity that is usually filled at the current rate, which is why the outcome is less damaging than it feels.
Questions readers ask
Why is my second job taxed so heavily?
Usually because your tax-free allowance is allocated to the first job, so the second is taxed from the first unit. Ask your tax authority about splitting the allowance.
Do I have to tell my employer about a second job?
Many contracts require disclosure or consent. Check the contract, and check whether any exclusivity clause is enforceable where you live.
