which category should stock bought for resale be put in, I think I have mistakenly put this into stock (asset) maybe should have been general sales?
I use general purchases, then journal the value of stock in hand from “closing stock” to “stock” at year end and back to “opening stock” the next year. That way your full year P&L shows the right total for cost of sales - what you had at the start plus what you bought during the year minus what you had left at the end.
