Ask questions before you list with a flat fee MLS company.  It is common practice to entice a seller with a low cost MLS listing.  It is not all inclusive.  

Most sellers need help with contracting.  This is when the extra fees are incurred.  You may be charged an additional "flat fee" for the contract negotiations.   There are also companies that will charge a percentage for contracting which means that you are no longer paying a flat fee!
