What is the lowest price I can charge for a SaaS plan?

There is a minimum advertised price (MAP pricing) of $97 a month. The plan you sell needs something you charge for that is at least $97 a month.

Votel does not recommend selling at $97. It undercuts the value you deliver and makes support hard: if 50 clients pay you $97, you are supporting 50 clients and may not have the money to hire support. Build the offer around the outcome you deliver and price it on that value.
