The module adds an ISBN column to the invoice table before ordering on OpenCart. The ISBN code is used as an identifier in the publishing industry, but this field is often used to store additional product parameters. You can change the title of the ISBN column to any other.
To add an ISBN to your account, just install this extension and update the modification cache.
