Managing Third-party Billing & Reselling MODX Cloud.
Currently there is no way to split or segment different projects in MODX Cloud for different payment methods.
This is occassionally requested as a way to functionally act as a Reseller of MODX Cloud. We've been there and we get it, but we do not offer that at this time.
If you're looking to generate additional income from MODX Cloud, we suggest joining our referral program.
If you absolutely need to pay with different billing methods for different clients, you must open separate accounts, and grant your user access to them.
