I am interested in this, I participated in some tests on a few ecommerce sites in the past and it seemed to not make much of a difference, except for very new b2c apparel type companies that had no name recognition with consumers. In those cases Paypal did help some, but honestly branding, messaging and other things mattered just as much if not more. The sample act of having a prominently placed phone number on the site we found would lift sales, having a real address not a PO Box etc, would lift sales etc. Consumers feel better if they can find you and talk to you other then via just email. This also changes demographically too as we found. You mentioned subscriptions, so I am assuming this is some type of B2C app or B2C service? Can you say what industry and what it is? e.g. Service, App, or ? And what is the typical transaction amount? This all likely is a factor too. Also, you mentioned users preferring Paypal over Stripe, in 90% of our cases it was Paypal or the "business", clients never knew the business was using Stripe or First Data etc. Never tested that part on consumers decision process though, e.g. Stripe checkout vs Paypal checkout.
