If you need to add a digital signature to your transactions, you can scan and add them into QuickBooks Desktop. To begin, write your signature on a piece of paper. Next, scan the image to your computer at an 11:3 aspect ratio, and we'll size your signature then place it above the signature line on Intuit supplied checks. Finally, save the image in .bmp, .jpeg, .png, or .tiff format.
Once done, you can follow these steps to add and use the electronic signature:
- Go to File > Printer Setup.
- Select Check/Paycheck from the Form Name drop-down list.
- Click the Signature button.
- Hit the File button and find the file that contains the signature image, then select Open.
- Press OK in the Signature window, then select OK in the Printer Setup window.
