Possibly Incorrect Pricing Calculation in Product Upgrades

[Humanbeing]

Create two Products (each with its own Configurable Options)
Price for 1st Product with 1 Seat is $1, and 2 seats is $2.
Price for 2nd Product with 1 Seat is $4, and 2 seats is $8.

Client buys 1st Product with 2 Seats. Total paid $2

Client then wants to upgrade 1st Product to 2nd Product
Total price for 2 seats for 2nd Product is $8
WHMCS should show price for upgrade as $6 (because client has already paid $2)

But WHMCS shows upgrade price as $2.
Looks like WHMCS is not considering this is a 2 seat upgrade but as 1 seat upgrade which is why it's showing price for 2nd Product for just 1 Seat, instead of 2.

The correct behavior should be as follows:
An upgrade from 1st Product with two seats, to 2nd Product should be for two Seats not one Seat.

Am I missing something?

Not missing anything, the product upgrade has never really worked and is widely ignored as being an issue

In WHMCS the upgrade of products and configurable options are considered independently. Once the client has upgraded their product, they can then upgrade the configurable options, and the pricing will be updated to reflect the different pricing scheme for the new product.

We have a feature request to consider adding an option to do just this here: https://requests.whmcs.com/idea/client-upgrades-should-offer-configurable-options-and-confirmation
I encourage you to add your votes and comment to this request. The more votes an idea receives, the more likely it is to be considered by our development team for potential inclusion in a future feature update.

If a client already has signed up for 2 or more Seats in one Product, he would still need 2 Seats when he upgrades to 2nd Product. If a Product Upgrade means, he will lose 1 seat means he will lose data set up with that one lost seat. 

The way things are, WHMCS Users will have to chase clients asking them to log back in to client area to increase Seats in "configurable options" once again after the upgrading their Product.

This is impractical and cannot work.

As example of this problem is a client signing up for 5 Email Accounts in PRODUCT 1, and the client upgrades to PRODUCT 2 to increase their web disk space. The result would be client losing 4 Email Accounts immediately after the upgrade.

Hopefully WHMCS will fix this soon.

that feature request is at least 7 years old... do you expect it to be added any time soon? I bet everyone else who replied to that thread expected it too at the time.

True that. 

Let this thread be the new tombstone of this essential feature to look back at another 7 years later.

If you find a company that will do whmcs an affiliate deal to provide such a "value added" service they may add it quicker.....  😛

It really is  a laughable state of affairs  - having been using WHMCS for 6 months now I am really at a loss as to how they have the market share they do/had - it really is a staeming pile of bodges, badly (or not) thought through ideas and then badly or only partially implemented.

I will be abandoning the product as soon as I can - there are just too many fundamental flaws which would cost me more to have fixed as custom development, assuming they could be fixed, and then to have those customisations at risk from every WHMCS version upgrade than migrating to another product including any customisations needed - plus new customisations to fix the bugs in each of those releases. It simply isnt a sensible commercial model ....
