I am using stripe for online payments but also users can pay offline (cash or check). I want to centralize all my invoices/charges in one place (stripe).
I am not sure if I can add offline payments (cash or check) to stripe or not. I guess I can if I created customers, invoices, charges with livemode=false for my live keys.
Is this feasible and will stripe accept to have some (customers, invoices and charges) with livemode=false and others with livemode=true?
If yes, should I fill fake credit card info or should I set is nil?
