>Can you imagine where half the SaaS startups will be without recurring credit card subscriptions?

I have done quite well opting not to use recurring credit card subscriptions for my SaaS, imho.

If you make a good product, customers will come back to use it again and again. They won't just forget about a product that worked wonders for them.

If you can't succeed without recurring billing then your product probably isn't good enough to succeed anyways.
