how to convert number of units to cases

So in my products list, I have everything listed as price per units. I sell tape and I have my list set up so that it’s $1 per roll/unit, $2 for 2 rolls etc. But because there are 72 rolls in one case, and customers purchase the items by the case, is there a way to convert the number of units into number of cases for the quote?

Because currently my quotes list “72” for quantity. I do have a note on my quote that it is price per roll, but I would like to be able to have the number of CASES show up on the quote rather than number of UNITS. I need the price to still be listed per unit in my product descriptions, but I just would like the person on the customer-end to be seeing how many cases they’re getting rather than units because it will be less overwhelming. Any idea how to do this?

Why don’t you have a different product for the Case, costing $72?

Then you could add by cases, so 2 units would be 144 rolls. Would this work for you?

That would be fine as long as it auto calculates the total number of rolls, I just prefer it the opposite way around since I’m getting calls where the client is asking for a quote for x number of rolls, I want to be able to tell them that is y number of cases. so it sill not work not to autocalculate.

If you really need this customized you’ll have to look at the code, maybe here
