Ihave very little cash and yet he says that i had a good year with $15,000 net income. he said it was because we use accrual accounting (whatever that means). i know i paid 6 month’s rent ($1,400 a month) in advance at the end of the year. i also paid my insurance for the next year. insurance cost $6,000. i have several customers who had a lot of services done on credit and haven’t paid yet. i think that totals $11,948 owed to me. can you explain?
