Well with 400 annual subscriptions on this plan, it will be a loss of time each year.
Further this plan is used for business companies and will artificially create duplicate invoices with alternate invoice numbers. We'll be obliged to make manual "avoirs" each time as we do now, that's just crazy as CBSubs is not good for manual things.

This would be good to find a way to avoid it if any.
Is it possible to change this plan with the price directly coming from a cb field instead of going through the subscription process ?

It probably needs to do the existing basket check after it runs totalizers so CBSubs Promotions and CBSubs Tax calculations can be factored in.

Yes that would be very good

Depends on how dynamic your price is. If you need it truly dynamic based off the value in a field then CBSubs Promotions is the only solution

Yes unfortunately we need a special computed price for each customer of this special plan. We plan to migrate them but it will take some years and old customers will stick to their old prices

You can hide a plan based off the status of another under the Workflows tab. Hiding a plan has no affect on their invoices page.

I dont find the way to hide it when there is a valid subscription for a customer. We unpublished it, set new inscription and renewal to no, restricted it to super admin but it's still visible when I go through a customer page.
As it is an old free plan that we are talking about and not the above one, would it be safe :
- either to use the mass tool and set all subscriptions to expired,
- or simply remove it from the DB and remove all attached subscriptions ?

thanks for all

If the free plan isn't used anymore you can set it to stop allowing new registrations and upgrades under the Workflows tab entirely then under the Pricing tab set it to be non-renewable. This will allow existing subscriptions to it to continue until they expire, but won't let anymore subscribe.

Thanks, that's what we did but the point is that the subscription is still visible in the client CBSubs tab, even marked as expired and even if we unpublished the plan.

Is it normal ?
How can we hide it except by css ?
