Product sales - Linked purchase/sale with COGs reporting per Item
We are a design firm that sells non-inventory goods - we might purchase a faucet from a wholesale vendor, want to mark it up for profit and then re-sell to our clients. This cannot be a unique scenario for other Xero users. Everything we order is one-off because every design is different. On the back end, I would like to seamlessly connect the client purchase to the vendor purchase - see my cost of goods AND profit for each item. I don't want to have to manually enter a marked up price for each item I sell. On any given job, I might sell 100's of items and this could get very time consuming while also creating room for mistakes. This really seems like a basic function that should exist in any accounting software. When I run my p&l, I should see the total of each for a given period, product sales, design fees - this is my income... then I should be able to see my Cost of Goods Sold - this is an expense - and my net revenue would be the difference between these 2.
