Raising a price without losing the client
Never open with the price
A price that arrives first is a demand and gets negotiated. A price that arrives after two minutes of something the client did not know is a consequence, and gets accepted.
Spend four fifths of the conversation on the change in your trade. Spend one fifth on the ask.
Make it their gain, honestly
There is a real benefit to the client and it is worth saying out loud: if someone is hurt in their home, an insured and employed crew is your problem rather than theirs. If someone calls in sick, there is a bench.
Do not overstate it. The point is that they are buying something different, not that they are being rescued.
Cap the first year
An account that has been under-charged for years cannot be corrected in one step without the conversation turning into a negotiation about whether you were wrong before.
Hold every client to the same maximum rise this year and let the rest follow a year later. It costs you something — work out exactly how much, so you are choosing it rather than drifting into it — and it makes every call easy.
Answer the objection once
Say the reason once, well, then ask a question. The person asking the questions is running the conversation. Defending a price twice turns it into a thing to argue about.
