Self-Employed - A Question Regarding Stock

buchloe

I've scrapped many of my own computers over the years and built up a small collection of spare parts (RAM, power supplies, graphics cards etc.) "in case of emergency"

Can I now use and sell these parts in the day to day running of my business? If so, how do I go about it because they wouldn't be shown as being bought from anywhere therefore have no purchase receipts for them, but they would be sold and claimed as an expense.

I was thinking along the lines of selling each part from myself as a person to my business as and when they are required, would this be acceptable?

Thanks in advance for any advice
