QuickBooks integration (start with empty company file?)

I've not opened my nopCommerce store yet, but I am looking at the QuickBooks integration piece. In the QB instructions it says "Make sure your QuickBooks company file is empty before enabling integration" or something to that effect.

Why? I have an existing quickbooks file. Why can't I start importing orders once I start using nopCommerce.

Bump: why???

You can use existng QB company file but you'll not be able to import orders for customers that already exist in your QB database because current QB integration supports only one-way integration (nopCommerce to QB)

Thanks for the info. That's all I expected it to do, so perfect! The warning made it seem like you'd see corruption in your QB file if it wasn't empty or something...
