TOP-UP BASED ACCOUNTS (WITH STRIPE)?

We got contacted by a Fortune 500 company that absolutely loves our product.
They want to roll out our software to hundreds of sites, with the option to
scale to many more.
The use-case is quite straight forward for us, with one caveat: they want the
end customer (their customers) to be able to top-up their accounts on our system
(something like a digital wallet).
This means, we need to let our customers collect payments from their customers:
i.e. the customers of our customers can top-up their account balance with any
chosen amount.
Can anyone share their experience with such process? Is there anything special
that we need to be careful about (contractual, security)?
Very important for us: does Stripe offer such feature?
