Hi Emily. I actually had the same question as Annabel, except I'm not VAT registered. I've recently gone self employed but purchased my computer a few months back. I joined Quickbooks Self Employed today and connected my bank account, found the transaction to Apple for my new computer back in July and marked it as 'other business expenses'. But reading your advise here should I manually enter this as a new transaction, attach the receipt and enter the date as the 5th October (the date I became self employed)? Thanks!
