In order to find out if she is in profit she must keep detailed accounts. She can then work out properly whether she is making a profit week by week...for example on the debit side she would need to list stock bought, postage, packaging, printer paper, printer ink etc etc..as is appropriate for her business...the list could be huge although not add up to a great deal....on the other hand she needs to list what she sells and the price paid. From this she will be able to work out profit/loss and whether to adjust her pricing. The summer house may well be an asset should she sell her house but I hope it is very secure if that is where she stores business related items
