How to create an invoice for freelance consultants

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 different concepts, the hours spent working on each one of them and, if it is the case, a breakdown of any products used for the job to be billed to the customer. The consulting 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.



Choose a note to include in the invoice

In order to add additional information, like available payment methods and bank account number, just select it on "Notes on the invoice".

How can I apply a discount rate?

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:
