Hi, so i was wondering how to buy materials for jobs, up until now I was just buying on my debit card in say wickes and then charging customer with like 10% profit on it, but im worried about large amounts of money going into my bank and I don't really know how to put that through quickbooks either. I started collecting cash for material for each job before I start but not everyone is keen on giving cash to somebody they just met without guarantee that they ever gonna come back... Any advice ?
