does anyone have any thoughts on how to add 30c to every line item for a particular product group that will neatly calculate towards the net/tax/gross amounts? is it a custom line field + workflow or is there something a bit more built in and dynamic as the sales order is created?

Like if the price of the item is $2.00 you want to make it $2.30?

yeah exactly

Does it have to be per line or can you just add 1 line at the bottom for the sum of all the extra $0.30 from all the lines

interested in either option

You could use a workflow to sum it all up into 1 line Just make a saved transaction search that adds your $0.30 per item/line that matches your item group. Then make it a summary search Use that search as the source of a custom field on your sales order Then make an Other Charge item for sale (Can be Fullfilled = ‘F’. And call it whatever you want. Then make a workflow and use the. Create Line action on After Record Submit In your action set the item to your custom item above, quantity is 1 and Rate is from your custom field above

that’s awesome, thank you!
