Private write-off of damaged product without stock module – how to record?

Hello

I have a question about how to correctly record a damaged product in Dexxter.

I made a purchase of 8 items (€55 incl. shipping). One item is slightly damaged, so I will use it myself and therefore not sell it via bol.

What is the correct way to process this? I am subject to VAT, but I made these purchases before my VAT registration was active.

Thanks in advance!
