People on a strict budget plan could put asside an amount to cover their average bill totals from each paycheck. If paid monthly, put asside half the usual bill amount, if weekly, then one eighth the usual. Those who have difficulty not spending this money could make payments directly to their service provider in advance on a regular basis, weekly, monthly, whatever works for them.
Any increase in the number of billing cycles is going to have the knock on effect of increasing the service providers cost base, if that happens, then prices will increase, which doesn't help anyone.
