Hello again and thank you for the additional information. First, it is important to understand that no one who does not have all of the detailed information about your entire work history and the Company's business, as well as the facts from the employer can tell you whether you will have a successful wage claim case. However, I can discuss the law and tell you what your options are.
Under the Federal Fair Labor Standards Act, which Kansas follows, there are certain types of employees who are exempt from the provisions of the minimum wage and overtime rules. One type are outside sales people. However, there are very specific rules as to who qualifies under this definition. You can see a discussion of that rule at the following link: http://www.dol.gov/whd/overtime/fs17f_outsidesales.pdf
If you either don't fall within that definition or you were also an inside sales employee, then you would fall under the minimum wage laws. In addition, it sounds like you might very well have a tort claim for fraud if your employer intentionally misled you about how you would be paid and intentionally hid sales from you.
I would strongly urge you to sit down with a local employment law attorney who deals specifically with employee wage issues, including commission agreements. They will be able to take a detailed intake from you and gather more information about the Company and their activities to help you decide your best course of action, likely suit, for commissions owed. If there wasn't an issue of hidden sales, I would say you would have a wage claim with the State. However, that would only get you minimum wage for the time you have worked at most. That isn't likely to be what you are looking for, thus you need to get a local attorney involved.
Please feel free to ask for clarification if needed. If none is needed, then if you could take a moment to leave a positive rating in the box above, I will receive credit for assisting you today. Thank you
