How do you spread billing across multiple providers if you don't yourself have PCI compliance to retain billing information? I guess you could seed it to multiple systems when the customer first provides it, but that's tricky without momentarily holding the billing information yourself, too. (I mean, you can cheat...) You can't really do paypal + google checkout + a real payment option all transparently to the user, though; you have to give them a way to pick and they may need to re-enter details.

The only way I've seen this done was segmenting by cohort or product -- i.e. recurring billing on one platform and one off billing on another.

I have seem multiple payment providers where you capture billing information each time, or where you are PCI compliant and keep the billing information yourself.

You become PCI compliant! That's the price you pay. Or you ignore PCI compliance and risk it. You probably wouldn't be surprised to learn that this is far more common then people will admit (and I'm not even talking about people in high-risk industries).

Anyways, there are a few ways you can do this without having to deal with PCI compliance, though it doesn't solve the problem as well.

First, you set up multiple merchant accounts. That way, for a normal transaction, you might send person A to provider A, and then person B to provider B, and then person C to provider A, so on and so forth. The goal here is to spread the threat over more than one provider. You don't just allow PayPal, and if PayPal starts receiving too many transactions, you remove it as an option for a while.

If you are limited as you mention to PayPal, Google, and a real payment system, the best way there is to offer encouragement to use one system over another. Which ever system you want to encourage use of.

You can also find a PCI compliant provider who you can then attach merchant accounts to. They handle the PCI compliance, you provide the merchant accounts.

Of course, none of these solutions are really as easy as just using PayPal. But then you start to see why PayPal is so popular. It's downright easy.

We were told (by Braintree) that you are not allowed to have multiple simultaneous Merchant Accounts (not counting Paypal). Is this not true?

Kristi answers you below (No, it's not a problem, at least, one I never experienced with any banks I ever dealt with). I will, however, say this: each bank is different. Trust contracts to define. Beyond that, get second opinions on everything. And then get contracts to back it up. You are dealing with money. Probably a lot of money. Spend the time to understand exactly what you are told. What you assume Braintree said may not be what they mean. And always get a contract.

Kristi from Braintree here. From a technical perspective, having multiple simultaneous merchant accounts shouldn't be a problem. If you'd like, shoot us some details, and we can see how we can help - [email protected]
