Can I jump in and ask a stupid question please?
In your accounts book, for outgoings do you write down exactly what you buy per item? As in 1 blow dry lotion, box of gloves etc. Or just put £xx spent at wholesalers eg?
Newbie here too lol
I make a note of the date, supplier, total amount and method of payment. You don't really need to break it down further than that as it will be detailed on your receipt/invoice which you keep.
What is good to have though are categories - products, rent, utilities, insurance etc so you can tally these monthly/annually and will know how much you are spending and whether or not you can save yourself some money!
