Place a test order on your Interchange catalog once you have finished installing. You should find a file in the orders directory with the name qbYYYYMMDD.iif. (YYYY=year, MM=month, DD=day.) Transfer this file to your QuickBooks machine and run File/Import and select that file as the source. This should import the customer and order into the system. If it doesn't work, it may be due to lack of sales tax or shipping definitions, discussed below.
