Customer analysis One of the key concerns when evaluating the allowance for doubtful accounts is a customer's payment history. HGL's accounting system tracked both the number of days taken to settle an invoice (DaysToSettle) and the number of days that the payment was late (DaysLate). As items sold in the last 30 days of the fiscal year are not "due" until the new year, it is reasonable to exclude these current items from our analysis of old invoices. i. Create a table displaying all of the outstanding invoices at year end. ii. Create a table displaying all "late" outstanding invoices at year end. iii. Create a table that displays customers who regularly pay more than 180 days late
