How'd you go about having Monthly fee, fixed add-ons and credit-based addons together?

Hi,

We're using WHMCS not for a hosting company but another SaaS business.

I'm planning to add two types of new addons (upsell) in addition to the monthly subscription payment. 

 

- Fixed price addon. which will be added to the monthly fee. What's the best way to do that? some kind of addon configuration or just duplicate all packages to have package+addon price as new packages?

 

- Credits addons (probably two different ones). These are one-time credits purchases (not adding funds as regular whmcs credit). For example the user buys 10,000 credits for $X  or 100,000 credits for $Y and uses it in our tool. When it ends he can purchase more credit packages. Pay-as-you go kind of credits. 

What's the best way to do that? 

 

Thanks

Is the addon using its own server module?  If not, using product configurable options that they can upgrade / downgrade might be a better solution.

One time purchases is a bit different and would likely be best handled within the server module it self by creating orders and invoices via custom functions.  Like a custom button that when hit purchases x credits. 

(server module as in what the service / product uses on the module settings page and doesn't have to literally a server)
