Sole trader expenses

I run a sole trader business and have just purchased an item of equipment using the business debit card. In reality, the use of this tool will be shared between the business and own use. The full cost has gone out of my business current account - how will I show a 50% contribution back into the business (from personal monies) within QF? Will it just be a case of Dr bank and Cr my nominal account for tools and equipment?
