Changing service items to inventory - how will effect past invoices.
They way our accounts were set up (years ago before me), is that sale items are considered service. So when we add them to an invoice, we also have to subtract the cogs and the inventory. I would like to change them to inventory items so we only have to enter one line item for the sale instead of 3 line items. Can I set them up to do this? And - How will this effect past invoices? Right now our inventory is set up backwards ( I think this was to offset the cogs) i.e.
1. Sale of item = 4
2. COGS item= (2)
3. Item inventory= 2
