How do I raise my prices without losing my customers?

If you are provide tremendous value to your customers; If you are helping your customers to get the results they are aiming for; If you help your customers to generate more make money or/and reduce their cost
You should definitely raise your price by 2X, 3X or 4X for the services that you are the EXPERT, the reference!

Please understand that by raising your price you will lose some customers...But ask yourself are these really your customers or you are their little b*tch?

If your customers can't value your services as an expert and Nickel and Dimes you. Send those customers to your competitors ;) Maybe is about time for you to find new customers that respect your time, skill and talent

Example: I prefer to deal with 10 clients that pay me 10K each than 100 clients who are paying 1000$ each.

How do I price our new products without pricing them out?

It depends what you want to do!
