NO! All of our software packages have a flat-fee, except one. If you want a variable-rate contract, we offer it to those organizations who are just starting out and have NO IDEA how much money they will raise. We call this our Starter Package and if you plan on having an auction that would raise less than $5,000 – it could be a good place for you to start. Contact us to inquire about our starter package and see if it is a fit for you.
