It's easy to set up products, coupons, pretty much all the choices I need to make my clients experience easy & simple

Wish they had an app, that would make my job easier to collect my money from one place only.

Mostly great, like I said, the learning curve isn't the shortest, but as they have lots of options (that, after going through that learning curve you'll find they're needed in order to give your customers the best options and support) you'll be able to offer a great service for your clients, no need to get in trouble with clients because of the payment gateway.

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).

You can collect payments quickly and you know it’s secure.

Fees and high and it’s hard to track customer payments.

Stripe Billing was easy to use overall, simple enough to deploy, and has a wonderful support portal and team to solve any other issues you have!

I used Stripe to manage Saas recurring billing with a few unique models, and it handled each of them after some integration work. It is a very product/business friendly tool that makes it easy to spin up new SKUs/products, discount dynamically, and analyze your sales. Stripe also integrates masterfully well with other reporting tools. I appreciated the work they put into automatically handling security and authentication as well, as it eased the burden on development.

Stripe can be hard to implement without at least some domain expertise on the team, and if your model is non-traditional. Doing things like highwater billing or multi-SKU billing on software utilization (seats vs. instances) can be a real challenge, and require coding on your side to roll up the right numbers. However, these are edge cases, and the core product works exactly as described.
