Each product style has different colors and so I used the Product Attribute Grid mod which allows a shopper to enter the quantities of  each attribute on the same page.

To add Net Terms as a Zen Cart payment option, I duplicated the Money order payment module.

Most Wholesale Purchase Order’s will also have a Ship Order date and a Ship Cancel Date which is the window of time that an order once placed will be accepted within.  There was some coding done for this by Peter Martin that contained a Ship Order Date.  I collected the changes he made and further added changes so that a Cancel Order Date was also included.

Additional download links to the mods.  Use these at your own discretion.  Make sure to back up all files and your Database before any installation. I am not responsible for you installing or using any of the following:
