I'm here to help make sure that the addresses on the checks will print correctly in QuickBooks Online (QBO).
Just to verify, is the address not aligning properly? If so, the compatibility is only guaranteed with checks specifically designed for QBO, which can be found in the Intuit Market. In the meantime, let's perform some troubleshooting steps that can help us isolate this.
1. Go to Expenses at the left panel, and click Print Checks at the upper right corner. 2. Choose a check and put a checkmark beside the date, then click Print Setup. 3. Select a check type and click No, continue setup twice. 4. On the Fine-tune alignment page, you must compare the alignment grid in the preview window with where it appears in the large square on the page. 5. Drag the grid inside the large square to the place where it appears on your printout. 6. Continue to fine-tune until the alignment is OK.
