4. Sexually-oriented or pornographic products or services

Would you constitute software development for the adult industry as one of those? I'm a freelance software developer.. Most of my clients are in the adult realm. I build sites for them, and software they buy from me. I'd love to use Stripe for processing their invoices (currently use PayPal) but that worries me that I'm gonna get canned because I wrote a CMS that is used on a porn site.

I'm not from Stripe, but I think I can answer: you're fine. Porn businesses are avoided mainly due to high fraud rates (including friendly fraud, when the cardholder buys the website services and later falsely claims their card number was stolen). It's not out of morality. After all, many brick-and-mortar shops have no problem accepting card payments for porn magazines. Your business isn't porn, and you're unlikely to get chargebacks, so you're good.

Judging from previous companies I've talked to, it doesn't matter. Porn is porn. They want no association with it period. Even if it's just code.

Can you explain the telecommunications equipment one? We're an electronic design company setting up Stripe (Australian Beta), and while we don't have any products in this category currently, we've been thinking of doing some networking/telecoms products...

It'd be good to hear more specifically what's not allowed.

You should probably reach out to them directly.
