Collecting CBSubs Shipping Address

I have a site with both paid and a free subscription option. When a paid subscription is purchased I need to collect a shipping address, but a free subscription does not need the shipping fields collected.

A few questions:

- What is the proper way of only collected certain fields based on a users subscription. I see I can limit access to the fields based on subscription but how do I dynamically provide access to the fields based on the subscription BOTH during registration and upgrade?

- How do I add other fields to a payment invoice? I only see ways to modify what variable a field is stored during the invoice address confirmation but not add new fields.

Thanks in advance.

You'll probably want to create fields within CB it self so you can collect country, state, address, etc.. without needing CBSubs to do it. Then within CBSubs > Settings > Display > Invoices map your CB fields to CBSubs.

You can't, there's no storage behavior for additional invoice fields.

Is it possible to get a CB tab displayed during an upgrade like they are shown during a new registration?

Don't understand what you mean. CBSubs at no point displays fields to update during the purchase process. Registration is just showing your normal registration form where CBSubs is a field on it.

Ok one more stab at this and then I'll just make it always optional.

My goal is to have a shipping address that is optional/not collected for free subscriptions and required for paid. Any thoughts how this could be done or just make it optional all the time?

Best I can suggest is use the hide fields on registration feature under the Workflows tab and have the free plan hide those fields. There's no conditioning that can be applied to the invoice address fields though. There's no functionality to toggle the required state of a field for a user.
