I think dual licensing AGPLv3 (or above) is the simplest approach. Include a separate paid (preferably straightforward) license and be done. Make it easy for people to pay you and make it easier to get refunds for any reason. Another option is to do what Duende did. I think Duende (Identity Server) handled the situation pretty well. https://duendesoftware.com/products/identityserver https://duendesoftware.com/products/identityserver > Standard License Pricing > Free for development, testing and personal projects—only pay for production.

It is not for scenarios where you redistribute IdentityServer, or build software for third parties. In this case you either need a redistribution license, or the end-customer needs a standard license. > For-profit companies/individuals with less than 1M USD annual gross revenue > Non-profit organization with a published annual budget less than 1M USD > Registered charities
