Successful software sales are a function of your support costs (assuming you've jumped the first hurdle which is writing a product people want to buy).
x% of your customers will take up y hours of your time. The software (and support materials) must be designed so that x and y are reducing in size as time goes by.
Free software with paid support is more like consultancy. To scale means more staff.
Paying for support is also more complicated - there must necessarily be a two-way conversation about work done, hours taken, etc. Collecting money for software is a one-way conversaton - here's the price, take it or leave it.
