I followed your guide but I still can't connect Razor to our company's Quickbooks

If you followed this guide Configuring Quickbooks and you are still having trouble with the configuration, a Razor integration consultant can assist your company in configuring QuickBooks; however, since Razor is not legally allowed to work on your company's production environment, you will have to sign a waiver releasing our Razor integration consultant from any unintended damage caused to your environment and there is also a one-time configuration fee of $250.
