Hello Dustin, there is an option in QuoteWerks to export to a csv file rather than to a pdf (right click on the report and export it to your desktop, manually changing the extension to .csv). If you were to do this then you could send the exported file to your supplier and then have them enter their pricing.
There is also an option under the Edit menu called "Paste Special" which allows you to input into QuoteWerks from an Excel worksheet. Once you have a template set up then importing would take only a matter of seconds. A combination of the above may be what you are after.
