How can we improve WHMCS?

With this feature, you can use the OrderProductPricingOverride to set a price for a product with a certain configurable location selected, for example, you have a product with locations and you have a location that needs to be charged extra (Miami) for example will be charged $3 extra from the rest of locations.

In the hook, we will set the product with this config option to have a price of $6.00, let's say the product itself was $3.

So now in the OrderProductUpgradeOverride we can get that override price from the product and use it to give the client the proper upgrade price.
