A developer to write a tool for you. You write that you have a software package for sale. Wouldn't you task your programmers to add this?
We have customers who buy our SaaS package, and if they want to convert their existing data (SO's Inventory, Customer information, etc) I need a tool that will do a "stare and compare" to match their existing tables/columns to ours, so we don't miss or loose anything. There are usually between SQL db's, not ACCESS to SQL. Any suggestions?
