Raise Your Rates With Existing Clients

Act as a pricing and client relationship management coach. I need to raise my rates for [CLIENT_NAME] from [CURRENT_RATE] to [NEW_RATE] — an increase of [PERCENTAGE]%. I have been working with them for [DURATION] and I am concerned they may push back or leave. Write a rate increase communication covering: a letter or email announcing the increase with the right notice period, how to frame the increase in terms of continued value, how to handle 'we cannot afford it' and 'your competitor charges less', the negotiation position to hold if they push back hard, and the decision framework for deciding whether to accept a counter-offer or walk away.
