Do you tell repeat clients that your rates change?

I've changed my rates twice and have only one repeat client so far. I did tell him about the rate increase because he had told me he wanted to schedule a stay about 3 months in the future. I raised my rates between stays and I told him I would give him the old rate on the next visit only. He was fine with it and paid the new rate when it went into effect for him.

That's totally up to you.

Speaking only for myself - if your rates are still within the norm for your area, I don't think it's necessary.

Personally, I have raised my rates twice since joining Rover.com and have never mentioned it to repeat customers. It does not seem to have harmed my business at all.

It is a personal call and you may choose to communicate the change to just some clients.

For example, if you knew one of your first clients and/or regular frequent clients (with a dog that you liked hosting) previously indicated any hesitancy to pay fees based on financial difficulties or other facts, you may start a conversation with them to see if that would impact them booking with you. Some pet owners may not feel comfortable bringing up the rate change and may feel obligated to look around for lower cost alternatives. Of course, it's completely your choice if you want to offer a custom quote at any time. However, after seeing your current rates, I don't foresee your clients having an issue with the prices.
