If my invoice is not showing the balance it says its hidden and I did not change anything. Any ideas how to fix this

Thanks for reaching out, Wendy. We can change your customer's invoice template to show the balance. 

If you refer to the invoice page and you see the word "hidden" next to the balance due, it means that this information will not appear when you print the transaction. Only the total amount appears on the printed form. See the screenshot below for a visual reference.

Please know that the Balance due (hidden) note is generated by the system. If you want to have this information show up when you print the invoice, choose a different template instead of the Modern one. Refer to the process below on how to do it.

You can also customize the appearance and layout of your invoices to enhance your business's communications. This lets you decide what information you want your customers to see.
