How do I indicate that I do not want the "Paid" stamp to appear on paid invoices?

Hi lauram5,

Thanks for reaching out here.  With all QuickBooks Online products, invoices marked as paid will have the 'Paid' watermark applied.  This is set by default and cannot be removed or disabled.  Please feel free to submit a suggestion to our Development Team, to be considered for future updates.

Feel free to reach back out with other questions.  We'd be glad to assist!
