This can cause serious problems with back taxes if the IRS rules against you. Also, if the independent contractor is injured while working for you, the workers compensation appeals board will almost always rule in favor of the employee and against independent contractor status, unless your worker genuinely has her own business. This means you may end up paying huge sums if one of your workers becomes disabled while you dont have insurance. In other words, trying to save a few pennies on this insurance is just not worth the risk.     Once you arrive at a good estimate for your total insurance bill, inquire about deferred payment programs.

The program you need depends on how big your business might grow to be, what extra features like statements or payroll you want the computer to provide and so forth. You can research the different programs yourself, but remember to keep in mind the features you may need later on after your business has grown. Or you can look into an outside service, which may recommend a program to fit your business and computer, set up the books and run parallel for a month or two to make sure that you dont lose any data. The systems can be very handy and time-saving if you have no strong attachment to a paper record, or are willing to print out the documents you may want.     When designing a bookkeeping system for your business, remember that it costs a lot of time and money to change it-make sure it really fits you and your business.
