Cal's Carpentry is considering outsourcing its accounts re- ceivable function. Currently Cal employs two full-time clerks and one part-time clerk to manage accounts receivables. Each full- time 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 Receiv- ables Group (SBARG) specializes in handling accounts receivable for small- to medium-size companies. Doris Roberts from SBARG has offered to do the account receivables for Cal's Car- pentry at a fixed cost of $75,000 per year plus $30 per account re- ceivable. Next year, Cal expects to have 2000 accounts receivable.
