So as long as your growth rate is that low you'll do fine. It's when your growth
rate increases that you have to be careful.
> If we have a 15% charge failure rate (to put the approval rate backwards), that's normal, you think?
That's fine, really. Pretty much on par of where I am, completely different service but all the same mechanisms apply.
> Historically speaking, how many of your charge failures have been due to things that get fixed -- expired cards, maxed out lmit
Expired cards are the 'killer' of most accounts, especially if you charge a low amount, the sweet spot is about $20 /mo, so we charge (deviously) $19.95, that way we extend the total $volume per account at the expense of our short term income. 619.95 > 3$24.95.
Maxed out limits only happen around Christmas, and our IPSP takes care of that by retrying on the charge a few weeks later.
> and how many are signs of a fake/worthless account?
Hardly any. Those chargebacks we do get usually are attributable to identity theft and outright fraud. That sucks because as a merchant you have very little tools to combat this. VBV sure helps though.
