# Editing Invoice References

You can change the reference used to issue new invoices through the **Settings** section of the Admin Panel.

          Changing your invoice reference format only impacts future invoices.

          

If you want to change the reference of an invoice you've already issued, you'll need to open the relevant invoice and then click on its reference to edit it.

          Invoice references have a **255 character** limit.

          

## Editing the Invoice Reference Sequence

1. Log in to [dashboard.nexudus.com](https://dashboard.nexudus.com/) if you aren't already.
2. Click [**Settings > Invoices and tax > Formatting**](https://dashboard.nexudus.com/settings/1/0/3).
3. Edit the **Invoices reference format** and **Invoice drafts reference format** as needed.

          The **{1:0000}** element is required.

          

You can edit the number of zeros to change the format of your invoice numbers.

*For example, if you define **{1:00}**, your **1st invoice** will be numbered **01** and your **105th invoice** will be numbered **105**.*

*If you keep the original **{1:0000}**, your **1st invoice** will be numbered **0001** and your **105th invoice** will be numbered **0105**.*

          Want to include dates in your invoice references?

          

Add **{year}**, **{month}**, and **{day}** to include the corresponding date elements.

1. Click **Save settings**.

Any new invoice you issue will use the new reference format. **Your invoice sequence won't reset.**

*If you already issued 200 invoices using the default reference format and then change your invoice reference to **NEW-{1:0000}**, the next invoice you issue will be **NEW-0201**.*
