How to create an invoice for computer engineers, programmers or graphic designers.

Our invoice templates create a unique invoice reference number automatically to comply with legal requirements. Your legal information and the one from your client will appear automatically once you have registered your customer in the program. Remember to modify the invoice date in case you are issuing the invoice in a different day from the one the service took place. Add the due date and terms of payment too.


Elements that your invoice should include

Describe the different services provided as difference concepts and the hours spent working on each one of them. The programmer invoice template that you can see above is an example of an invoice that uses the hourly rate system to calculate the total net amount. Visit the following link to see an example of and invoice billed by project.

The program will calculate the total automatically. Add the percentage of taxes if required.

You have two options: whether to apply a discount rate for a specific customer, or apply a discount rate only for some invoice concepts.

When you create a customer, you can set a discount rate for them to apply to all concepts of your invoices. The subtotal of the invoice net amount will decrease accordingly:
