I invite you to do a quick thought experiment.
Block 10 minutes in your calendar, with no interruptions or notifications to distract you.
Pick 5 of your existing customers that have been paying the same rates for the previous 18 months.
Write down 1 reason that stops you from increasing the prices for them.
1 different reason for each customer.

If you want to share the list of reasons with me, email me at askmanu[at]softfight[dot]com.
I will write back to you with my feedback and answers if you have any questions or dilemmas.
