Hi there, signgypsiesbaldw.

Thanks for stopping by the Community this morning. If you're trying to add a tip, there's a couple different ways. One way is to add the tips to your sales receipts. You can add another line for the tip by creating a service when making an invoice.

Please follow the detailed steps outlined below:

1. Click the Plus (+) icon at the top, then select Invoice.
2. Select the customer and enter other invoice details.
3. Enter the Service Date.
4. Under Product/Service, click +Add new, then choose Service.
   
5. Name the service as Tip, the select Undistributed Tips under the Income account section.
   
6. Click Save and close.
7. Once done, select Tip and enter the Amount.
   
8. Click Save and send to send the invoice to your customer.
