TLDR;
Add "quantity" column to "Review and Checkout" page and {InvoiceLineItems} variable if price rule being used has "Multiply Amount by Field Value."
Some customers use the "Multiply Amount by Field Value" setting in their price rules:
This is a great feature, but can lead to confusion for users in the (1) "Review and Checkout" page, whose content is largely static, and the (2) invoice created email/confirmation page that can both use the {InvoiceLineItems} variable and customize content.

1 - Review and Checkout page:
It's a common e-commerce convention to display the number of items of a given type on an invoice when there is more than one. The current UX for this in OW is that the applicant is shown the total in both the cost column and the total below when the "Multiply Amount by Field Value" option is used. The best current option is to add a descriptor in the Name of the price rule (making it something like "Additional Trophy ($500/ea)"). This is a decent stopgap, but still falls short of conventions as the user then has to do math to confirm how many items they've ordered or go back to the submission form to check.

I propose two changes to this page when the "Multiply Amount by Field Value" option is used:
1) Adding a column to the right of "Cost" that provides "Quantity" data.
2) Modifying the "Cost" column data to show cost per item instead of the total cost for that price rule could reduce confusion as well (since the total is shown below the line items anyway).
A rough mockup:

2 - {InvoiceLineItems} When used, this variable currently displays a table that's very similar to the Review and Checkout page (see below).
If this variable were to be updated to contain a new Qty column, it would improve invoice clarity for clients in other parts of the platform (invoice created email/confirmation page/etc.)


Thanks!
