4. Carolyn owns a small business, Snappy Frames, that sells picture frames. Carolyn says, "I let most of my employees be the CEO of their responsibilities. Trust is the key to my success!" Once customers place their order online and the products are shipped, customers will send their payment in the mail or by electronic fund transfer. Quinn, accounts receivable clerk, posts the journal entries to record the customer payments (Dr. Cash Cr. Accounts Receivable). Quinn files the payments received in the mail in the office and deposits them on a monthly basis.
