Environmental protection and animal welfare organization seeks MLM network software

We have just started as an environmental and animal welfare organization as a non-profit, unregistered association and are now looking for MLM network software. We do not sell anything.

The MLM (multi-level marketing) should meet the following requirements:

• Member recruitment in the network system
• Assignment of member numbers
• Bonus distribution (commission) for newly recruited members
• Structured in unilevel and with 4 levels of depth (members, family tree creation)
• Annual overview of accounts
• The other association members should later be able to view their respective personal member accounts with read-only access.
• Local or web-based
• Cost-effective

Two licenses (with all rights) are planned for software workstations. We work with MS Windows systems.
