Every type of business has its pros and cons. One obvious con that I can think of right away is collections. While most of the checks cashed by the center will probably clear, there are some, even payroll checks that may not clear. If that happens, it will be on you to try to collect those funds. There is also the security issue. For your convenience, I have provided a link to a webpage that discusses some pros and cons of owning a check cashing business.
Let me know if I can be of further assistance to you regarding this matter.
