Inventory Setup for Internal Consumption
I run a small construction company. We bulk purchase common materials & supplies to get better supplier pricing and general convenience. Example: Box of caulking tubes or bundle of rebar. Up until now, they were simply added under the COGS expense account, and used as we went from job to job. I'm now using the Projects module to better dig into project specific costing, and want to associate as best as we can those materials cost to a specific customer / job. More specifically, account for the pre-purchased items as assets until they're actually consumed and converted into COGS. Anything we buy and use immediately for a job is already costed directly to that project.
I have the inventory and purchasing modules turned on, have created items, and stocked some inventory from supplier invoices. What I cant figure out is a workflow of how to consume those materials from inventory into COGS for a particular Customer/Project. We don't "sell" any items to customers as everything we do is on fix cost contracts. We just use the items out of our internal inventory, or go and purchase one-off items for the specific job.
I've heard people say "purchase the inventory from yourself and cost it to your customer" but I cant figure it out. All the inventory examples I've found online are for retail type environments buying and selling actual stock items.
