Add a signature to the purchase order Add a signature to the expense of a check

Thanks for taking the time to post your concern here in the Community.

There are different ways on how you can add signatures on your purchase order, check or expense forms. You can either print the forms and manually add the signature or you can add it as an attachment.

If you want to enter it as a different field, I'd suggest sending us feedback through the Gear icon.

Also, if you want to customise your sales forms, you can check this article: Customise invoices, estimates, and sales receipts in QuickBooks Online

I'll be around whenever help is needed. Have a good one and stay safe!
