It has very little to do with being 'LowEnd', and much more to do with being a 'host-from-a-box' that doesn't do proper QC on new signups. If you let "Abc Abc" of "123 Fake st" sign up without a second thought, you're going to get abuse no matter what your price point is.
Just to put things into perspective - for years we were the "low-end" (back when that meant low spec, not low quality - who do you think everyone copied the 15$/yr plans from?), and I would *maybe* see 2-3 client-initiated disputes a year. The pricepoint/market/<other excuse here> isn't the problem - a 'provider' thinking that using WHMCS means he doesn't need to actually audit his business is the problem.
Well actually I was auditing my income and expenses for 2013 and the ratio of people doing chargebacks on paypal was higher than 2checkout last year.If you are receiving enough chargebacks and disputes for it to be such a major concern.. perhaps it's time to stop assuming the problem is with the clients, and determine instead what you're dropping the ball on to make that many people unhappy.
I handle all of the disputes and 80% of the time the client is being unreasonable - paypal gave the money back when they shouldn't have. If someone is suspended for abuse they usually open a paypal dispute.
