Choosing purchase category

I’m trying to find the correct category for accessories for workshop equipment - I don’t think they are a capital item as they are low in value but they aren’t repairs or consumables either. The ‘help me choose a category’ section doesn’t offer any suggestions.
Also, am I right in presuming if it was something that wears out after a while (eg saw blades) I’d put it as repairs & renewals?

You could use “Repairs and Renewals” for something like saw blades. If you don’t find a perfect fit you can always create a new nominal code under purchases >> overheads.
