Zero inventory, but oversold by one or two pennies.
I have several inventory items that have zero quantity, but show negative dollar amounts by one or two pennies. I think I know why this is, as we have made the mistake of billing 50% of invoices for upcoming equipment orders, instead of invoicing for parts only. This has cut parts prices in half with the other half invoiced upon job completion. However, some don’t come out correctly and are off by a penny or two on the final invoice. For instance, $692.25 was billed twice at 50% as $346.13, overselling the product by $0.01. Do I need to issue a credit memo for the few pennies to the customer, or is there another way to take care of this?
Since this is not an addition of inventory, but rather on the invoicing side, I am not sure how to take care of this.
