It's actually very simple.
1. RAISE YOUR RATES
2. OFFER PAYMENT PLANS FOR YOUR PRODUCTS OR SERVICES

I just had a client last week come to me who was charging way under market value for her services and I basically told her to suck it up and increase her rates by 400%!! Yes, I told her to raise her rates by 5 times what she was charging clients now. She almost fell off her chair (I think, as we were on the phone).

This new rate was actually the going rate for what she was doing. In fact I am paying someone to do it in my business right now every month!

Actually this happens all the time with services and products I actually need. When I run across people that I actually pay or could pay for what they do, I open my mouth and suggest they raise their rates! Am I a dummy or what? I could be paying much less for stuff if I would just shut up! Oh well....it's for the greater good.

So, this client of mine; if she takes my advice, she could literally increase her income by FIVE TIMES with no more work!

It could be that simple if you are not charging enough OR if your perceived product or service value is a lot higher than what you are charging. If you don't know what your value is or what the going rate is - ASK ME PLEASE. I see a lot of different businesses every month and I know how to get you these answers.

As for payment plans; many peers of mine in the info-product industry (selling online products and services) find that they get a lot more orders and purchases if they offer payment plans - especially OUTRAGEOUS PAYMENT PLANS such as 18 payments of $19.95 or something like that. I do this for some of my products and services even if delivery of those products or services is well before their last payment due date and all of the payments are made online of course too by automatic payment which is the key. You don't want to go trying to collect checks after the fact, that's for sure.
