Stripe Billing

I like that I can use it directly as well as integrate it with my own point of sale system. I used to have to pay for a software that could do both one time payments and automatic recurring subscriptions but this beat them out. I work mostly from my computer and its easy to get into and if I can't remember how to do one functions I can easily get what I need from their support forums or support chat.

Only thing this won't do is notify me if a payment doesn't go through, but there is a quick fix for that. I just use zapier and now I receive an email notification if that happens. Oh and I had a chargeback once I'd like to see an option to upload multiple documents for disputes not just one. I get that there is only so much file size available in messages plus my contract took care of that issue.

They take privacy in a very serious way. And they know their product is used mostly by developers, so their site has plenty of support, examples forums and every kind of resource that makes it easier for developers to implement payments on any platform. Also, they have options to manage clients and subscriptions that can be billed for in a fixed period of time, give them free trials, etc. Their commissions aren't the cheapest, but I consider they aren't also very expensive.
Another thing that we liked is that they keep developing their offer, like accepting payments via convenience stores (currently in beta while i'm writing this review)

It has a big learning curve. At first it's difficult to get familiar with all the concepts they use for their different parts of the process, I wasn't able to find a simple tutorial on their site (found some in external sites).

I like that I can take payments via my ecommerce website.

I cannot input a custom note to the customer. I have to have too much info to run a credit card such as billing address. This is very cumbersome. I need to have a credit card swipe to bypass having to key in a lot more info. I have asked customer service about this and they say someone will call to discuss but that has never happened

Powerful invoicing system
Recurring Payments capabilities
Great graphical dashboard
Top-notch customer support

The fees might be any lower than they are. 2.9% plus $0.3 plus 0.5% per recurring payments, increase the prices considerable, without counting on the federal taxes.
