Existing referral is clear and aims at inviting new DO customers.
There is another way to add customers with partners who implement added value applications based on DO services. For example allows customers to obtain application software server based on DO droplet.
In case case DO obtains new customer indirectly with payments provided directly from the partner who resells droplets with installed own applications. Logically it is the same as referral and the difference is only in the credit recipient.
If implemented it would allow us as your partners decrease service fees for our applications and facilitate joint business development
