How can we purchase/drop ship multiple items from different vendors and sell them as a kit on our website?

We have been using Netsuite for a couple of months now and we are having loads of problems on the inventory management side.

TL;DR – How can we purchase/drop ship multiple items from different vendors and sell them as a kit on our website.

Currently the purchasing process looks something like this: Customer wants kit XYZ from the front end of our Magento 2.4 Ecommerce website. Customer places the one item kit (XYZ) into their cart and purchases it. We check to see is we have part A, B, and C in stock. Turns out we have A in stock but not B or C, so we drop ship product B from vendor alpha and part C from vendor beta.

XYZ is made up of part A = $9.99 part B = $45.99 and part C =$43.99 which totals to $99.97 With the MAP price being $100 (the price we show on our website and sales order), we can’t use Groups in Netsuite as that will equal $99.97 (yes our vendors care). We also can’t use kits since you can’t put them on a PO. The parts aren’t assembled in any way and as far as I know, assembly items are handled differently by accounting, so that doesn’t work either.

Is there a Netsuite solution to this problem? In my mind, groups would work if we could change the price of the total group and not show the individual pricing on SOs/webpages. Kits would work if we could put them on a PO. Any advice is welcomed!
