Within ecomdash you have the ability to generate bar codes for your products on the Inventory Management screen. The value of the bar code can be your SKU or your UPC.
To change which value it defaults to you can follow the instructions below:
1. Navigate to Settings > Inventory Settings > Inventory
2. You will see a drop down under the bar code options. You will select from the drop down which option you want your bar codes to generate off of.

If you have a larger SKU Number, you do have the option to stretch the barcode to accommodate the larger SKU number.
From there you should be all set to see your bar codes generate with the new setting you have selected.
