Hi, everyone.

I'll be sharing the steps depending on the QuickBooks products you're all using.

For attainmentcb, currently. QuickBooks Online only offers basic functionality in creating and printing checks. Since attaching an e-signature is unavailable, I suggest affixing your signature manually on every check you’ve printed or integrating a supported third-party application.

For KWalkerjdg, QuickBooks Desktop has a functionality to add an electronic signature for checks and paychecks. I'll show you how.

First, create the electronic signature:

1. Write your signature on a piece of paper.
2. Scan the image to your computer at an 11:3 aspect ratio. We'll size your signature and place it above the signature line on Intuit-supplied checks.
3. Save the image in .bmp, .jpeg, .png, or .tiff format.

Then, add and use the electronic signature for checks and paychecks. Here's how:

1. From the QuickBooks File menu, go to Printer Setup.
   
   
2. In the Form Name dropdown list, select Check/Paycheck.
   
   
3. Choose the Print Signature Image checkbox.
4. In the Signature window that appears, select File.
   
   
5. Find the file that contains the signature, then click Open.
6. Select OK in the Signature window, then hit OK in the Printer Setup window.
