For a fixed-priced service intervention that has an estimated number of parts, say a new-build boiler installation, how do we consume additional storable products that are not charged to the customer?
Say that the customer has agreed to 10ft of ASB piping and we end up using 12ft but will absorb the 2ft ourselves and not charge it on. We do want to track cogs properly and see the additional 2ft reduced from margin so that we see the true cost.

Is there any elegant way to do it? I thought of creating a zero-price internal invoice for the items not invoiced but wanted to check if there was a simpler way.
