if i orders two or more quantity of same orders then the quantity adds up automatically e.g
1 Chilli 9
1 Chilli 9
becomes
2 Chili 18
but if add same items with modifiers the quantity dont sum up e,g
1 Chilli 9
1 Chilli 9
how do i add quantity of same item in bill ?
If they have modifiers then they are not the same item. How would you show which one has the modifiers?
if modifiers are added with extra stuff with different price then it should be considered different dish on bill
if modifers are added for comments only then the quantity should be added up for bill
Can you show use case example? Sounds like you may need a different approach if your using modifiers for notes.
let say i have order:
1 Paneer Chilli $4
1 Paneer Chilli $4
*extra spicy
1 Paneer Chilli $4.50
*extra butter
so
if Item modifier exist
check if item price * qty == total amount * qty
then
update existing item qty
this is what i was thinking if you have a better and simple approach advise so
How would you know how many to make extra spicy if you combine them?
i want to combine the quantity on bill only not in kitchen order
I have the same issue with madiha, so i’m using notes instead of order tags, add {NOTES} in kitchen template and remove {NOTES} in bill template. Any custom tags that don’t add product price i’ll type in the “Notes” for kitchen use only.
Will take any suggestion 
example of what i wish.
Kitchen
1 beef steak $10
*Rare
1 beef steak $10
*Medium Rare
1 beef steak $10
*Extra Sauce $2
Bill
2 beef steak $20
1 beef steak $10
*Extra Sauce $2
I have tried to use “Portion modifier” and “Custom Product Tag” as substitute for “Order tag” but it’s not worked in this case. I think the answer is in Bill template. But i can’t find the right value tags or the syntax combination.
I’ll add another merging method that merges order tags contains price and removes remaining order tags, on next update.
leaving out no excuse for not to update to v5
