Hi there,
Including invoice numbers is a great way to keep track of your transactions. I want to make sure you can add this field to your invoices.
Use the Custom transaction numbers feature to set your own numbering preference. This adds an Invoice no. field where you can enter any number or letter format you want.
1. Select the Gear icon.
2. Click Account and Settings.
3. Select Sales, then select anywhere within the Sales form content section.
4. Check the box next to Custom transaction numbers.
5. Select Save and then Done.
Open an invoice or any sales form, and in the Invoice no. field, enter the custom number or letter sequence you want to use for your forms. The sequence you set here applies to all sales forms.
If you have any other questions, let me know. I'm here to help.
Have a nice day.
