Is there any solution for adding one more free item in invoice when customer buy some qt. of the same item?

the obvious way to add 100% line discount somehow didn't work. Customer should see in invoice that one item is for free.

Hi

One solution would be to add the articles in negative, which would look like this:

Another option is to create a similar item with a RRP of 0 so that you are not affected by stock.

I agree with @Abhishek easiest way is to add a line with 100% discount. If you want that free line to be created automatically, you can achieve it with a small code customization.

// Event Subscriber on Sales Line Insert OnAfterInsertSalesLine(SalesLine: Record "Sales Line") begin // Check if the item qualifies for free item if (SalesLine.Type = SalesLine.Type::Item) and (SalesLine.Quantity >= 10) then begin FreeLine.Init(); FreeLine."Document Type" := SalesLine."Document Type"; FreeLine."Document No." := SalesLine."Document No."; FreeLine."Line No." := GetNextLineNo(SalesLine); // helper function to fetch next line no. FreeLine.Type := SalesLine.Type::Item; FreeLine."No." := SalesLine."No."; // Same item FreeLine.Quantity := 1; FreeLine."Unit Price" := SalesLine."Unit Price"; FreeLine."Line Discount %" := 100; // make it free FreeLine.Insert(true); end; end;

You should be able to do this by adding a full line discount but you have to tab out of the field so the value sticks. Or you can do this by setting the Unit Price to zero for that line, then when you tab off the Line Amount and Amount Incl VAT should be zero.

what did you mean by 100% line discount somehow didn't work?

Is it because your invoice layout doesn't support it?

why not post using 0 unit price?

Hi,

Applying a 100% line discount may seem like the obvious solution, it doesn’t always render clearly on the invoice layout, especially when customers expect to see a distinct line showing the free item.

Here’s how to approach it:

Option 1: Add a Separate Line with Zero Price

On the Sales Invoice, add a new line for the same item.

Set the Quantity to 1 (or however many are free).

Set the Unit Price to 0.

Add a Line Comment such as “Free item included with purchase” to make it clear to the customer.

This ensures the free item appears as a distinct line and is not bundled into a discounted total.

Option 2: Use a Non-Inventory Item for Free Goods

Create a non-inventory item called “Free Sample” or “Promotional Unit”.

Add it to the invoice with zero price and a clear description.

This avoids affecting inventory and keeps the invoice clean and transparent.

Option 3: Customize the Invoice Layout

If you're using RDLC or Word layouts, you can highlight zero-priced lines with a label like “Free Item” or “Complimentary”.

This improves readability and avoids confusion for the customer.

Option 4: Use Item Charge (Type = Charge (Item))

If the free item is part of a bundled promotion, you can use an item charge to reflect the promotional value.

Assign it to the original item using the Item Charge Assignment function.

This method is more useful when the free item is not a separate SKU but a value-based benefit.
