I thought the question was "where can I find the authentication code" not where do I find the field in which to enter it. I'm test flying this program and desire to see how Express Invoice interfaces with the Inventoria program. It's asking for an "authentication code" and I'm guessing I must purchase the programs before I receive one. But, in case there is some place or some way to get the code needed, I'm sending out this question. Thanks.
