What do you like best?
Just recently Stripe enabled invoicing, which is what I was needing. I like how easy it is to sign folks up to subscriptions (we are a SaaS biz), and manage accounts. Slack integration is nice too. Also, Stripe has alot of integrations.
What do you dislike?
Reporting is really minimal -- not sure why there isn't better charting capabilities. I don't think their subscription support is great either -- not quite flexible enough and I find myself having to develop too many discount codes. There's just alot of manual work to set up. Also, this is useless if you don't know how to code.
Recommendations to others considering the product
really look at the kinds of subscriptions you are offering and the work you need to do in setting Stripe up. Also, if you are looking for custom invoices with nice branding etc, you will need to integrate with a 3rd party software.
What business problems are you solving with the product? What benefits have you realized?
Subscription registration, billing and payments. I am finally able to send one-off invoices.
