Where do you get credit staff? You may have an existing employee who has worked for you for many years, who knows all your customers, and has no trouble getting your invoices paid on time. This is a common scenario in many companies. What will happen when this capable employee leaves the company or is sick etc.?
Some other companies have a bookkeeper who comes in once or twice a week 'to do the books' and chase payments. My experience is that the bookkeeper leaves very little time for debts, and has a general dislike of 'chasing debts'.
Most companies have dedicated Sales Ledger staff: again, my experience is that they would rather file documents for hours at a time than make one telephone call to a debtor. I would never suggest they would all avoid debts. If you have one that gets 'stuck in' you should look after them!
The other scenario is the business owner chasing payment. You may be very good at it, however, I am sure you would be better deployed at the core of your activity.
