How to Write a Rate-Increase Letter Clients Won't Push Back On (With Template)

Most firms put off raising rates far longer than they should, because the letter feels awkward to write and worse to send. The good news: the letters that get pushback usually share the same mistakes, and the ones that don't share a different, learnable pattern. Here's what actually works, plus a template you can adjust and send.

Why firms wait too long to send this

The fear is almost always the same: what if a client leaves. But the math usually favors sending it anyway. If a 10% increase costs you one client out of every fifteen but raises revenue on the other fourteen, you're still ahead, and in practice the actual client-loss rate from a well-handled increase tends to be far lower than firms expect going in. Waiting two or three years and then sending a larger, one-time jump does far more damage to client relationships than smaller, more frequent adjustments would have.

The timing that matters more than the wording

Send rate increases with real notice, ideally 60 to 90 days before they take effect, not two weeks. A client who finds out their rate is going up next month feels ambushed. A client who finds out three months ahead has time to process it, and it reads as respect for their business planning rather than something sprung on them. Tie the timing to a natural point, like the start of a new engagement year, rather than sending it mid-cycle with no clear reason attached.

The framing that actually works

The letters that land well share three things: they're direct about the number, they briefly explain why (without over-justifying), and they don't apologize for running a business. Letters that hedge, over-explain, or sound apologetic tend to invite more pushback, not less, because they signal the sender isn't confident the increase is fair.

Template

Adjust the bracketed sections for your firm and the specific client relationship.

What to leave out

• Long justifications. One clear reason is enough. Three reasons starts to sound like you're trying to talk yourself into it.
• Comparisons to competitor pricing. It invites the client to go compare, which isn't the conversation you want to start.
• An open invitation to negotiate. "Let me know if this doesn't work for you" softens the letter into a starting offer rather than a decision. If you're open to case-by-case exceptions, handle that individually and privately, not in the mass letter.

If a client pushes back anyway

Have your answer ready before you send the letter, not after the first reply comes in. Decide in advance: are you willing to hold the old rate for a specific client, offer a smaller increase, or hold firm. Whatever you decide, decide it before the conversation starts, so you're not making the call under pressure in the moment.
