Re: online payment option

It does look like Stripe has an API Key based authentication system which can be handled through Pipelines. 

https://stripe.com/docs/api/authentication

Without going through their entire API document I'm not 100% sure which endpoints you would need and so you'd need to map it out in more detail. I quick scan looks like the PaymentsIntent is what you'd want to focus on for a single payment transaction. Pipelines would be able to make the request to their API and log the information accordingly so you could write back to QB once it has been paid.
