Hi. I can't seem to get upgrades to calculate properly with the settings I've tried.

Here is what should happen:

Plan A - $5.00 per week
Plan B - $7.00 per week

User subscribes to Plan A on 8/18/11 with expiration date of 8/24/11
User upgrades to Plan B on 8/19/11 and expiration date should remain 8/24/11.

Upgrade should charge the difference of the 2 plans ($2.00) and the expiration date should remain the same.

Here is what is happening:

Upgrade checkout is charging the full plan price of Plan B ($7.00). And I believe the expiration date is also changing to a week later from the date the upgrade takes place.

We are using mandatory Auto-renew and ARB with Authorize.net. Prorate upgrade is turned off because we are not prorating by days used. It's a flat rate per week.

Plans are set up as Exclusive, other plans of same parent cannot be subscribed same time, but one subscription is mandatory. All plans are set up at parent plans.

Thanks,
Linda

I can deal with the expiration date, but when prorate is checked off, it's prorating by day rather than the full price of the plan. I need the upgrade to only charge the difference between the full price of the 2 plans, not by a prorated price per day of the initial plan.

If this isn't possible, I have a big problem.

Really desperate for an answer here... Is there any way to make the system calculate based on a fixed amount per subscription rather than by the number of days into the subscription? Our subscriptions are for a flat week rate which cannot prorate. Upgrades just need to calculate between the difference of the total rate.

Ahhh! That is an interesting solution and I think it just might work! Here's the monkey wrench... We actually offer 9 plans, although there are only 3 different prices...

I suppose I could change them to 3 plans using child plans for the options. Each plan with the same price has 3 options. Rather than using children I created 9 parent plans, but I guess I should rethink that...

Any additional suggestion in how to calculate the way you described between 3 plans rather than only 2 would be of great help.

Thanks,
Linda
