DemandTools is my favorite client application to support our Salesforce implementation

I am currently using the Find / Report IDs module in preparation for a data migration into Salesforce. I'm a consultant for a large printing manufacturer and I'm currently working with the Channel Program team. We are sunsetting two legacy systems for them and migrating both Accounts and Contacts for both. The Find / Report IDs module enables me to locate existing records in our system using a series of complex matching scenarios. The reason this is extremely helpful for us is that it eliminates manually work of searching each Contact and Account to determine if there is an existing record in Salesforce to avoid creating duplicate records. We have hundreds of records so this is saving us days of work! I'm an avid user of DemandTools and recommend it to many companies I consult for!
