Re: Bookkeeping-Inventory Question
If you're using Quick Books Pro and if the material you're purchasing is going directly to a specific customer, there's a category for "cost of goods sold" and you could charge it off directly to that job. If you have the type of company that purchases 50 rolls of NMC, 100 GFI receptacles, etc. and distributes them equally to each of your crews for use on various jobs you can use the "job materials" category and not charge it off to a specific job. When a crew uses any of these items they are itemized and billed to the specific customer. At year's end when you print your P&L statement it will start off with "gross revenue" (where all your customers' bills will be lumped together) less "cost of goods sold" and "job materials" (irrespective of whether all items have been used or not) and finally "gross profit". Then your "expenses" are deducted and you'll end up with "net income". What you have to be careful with when using this method is shrinkage (employee theft) because you are not keeping track of what is used and when.
On the other hand, if you have the type of company that keeps a stock of rolls of NMC, switches, receptacles, cover plates, etc. and distributes them as needed for each job, then you'll have to keep a running inventory and drive your accountant crazy at the end of the year. Personally speaking, I would rather have my supply houses keep the inventory for me rather than tying up my ready cash in inventory.
