4. Fast Finish, Inc. (FFI) has made a technological breakthrough in snow board finish application. FFI will apply the finish for $0.23 per unit in variable costs plus a fixed annual cost of $230,000.

6. Cal’s Carpentry is considering outsourcing its accounts receivable function. Currently, Cal employs two full-time clerks and one part-time clerk to manage accounts receivable. Each fulltime clerk has an annual salary of $36,000 plus fringe benefits costing 30 percent of their salary. The part-time clerk makes $18,000 per year but has no fringe benefits. Total salary plus fringe cost is $111,600. Cal estimates that each account receivable incurs a $10 variable cost. The Small Business Accounts Receivables Group (SBARG) specializes in handling accounts receivable for small- to medium-size companies. Doris Roberts from SBARG has offered to do the accounts receivable for Cal’s Carpentry at a fixed cost of $75,000 per year plus $30 per account receivable. Next year, Cal expects to have 2000 accounts receivable.

(d) What other alternatives might Cal consider in terms of his current staffing for accounts receivable?
(e) What additional criteria should Cal consider before outsourcing the accounts receivable?
