I'm delighted to have you here sharing your concern about Square payment options on your invoices, Li_R. Let me share insights to help you achieve this matter.

Creating invoices with several payment options is convenient for your customers when paying the invoice received. Please know that QuickBooks is always dependent on the information imported from your banking data to your company file. Thus, to help you enable and connect your Square account to the online program, make sure to link your bank account so QB then downloads your transactions and matches them to your Square entries.

Then, you can set up the Connect to Square app feature on your account. To do this:

1. Sign in to QuickBooks Online.
2. Search Connect to Square in Find apps.
3. Click Get App now and choose Get started.
4. Select Give permission.
5. Sign in to Square, then select the Square locations you want to sync.
6. Find and select the bank account you want to deposit to, then click Next.
7. Choose whether you want the app to import sales individually, or as a summary of your daily sales. Select Next.
8. Once done, select a starting date, then click Finish.

After setting up, the Connect to Square app downloads your Square transactions to QuickBooks.

For more detailed information, you can refer to this article: Connect your Square account to QuickBooks Online.

Once everything's ready, you can start reviewing and categorizing your transactions in your account to make sure all data matches your bank and credit card entries.

Moreover, I'm including this guide to help you reconcile your accounts, so they match your bank and credit card statements: Reconcile an account in QuickBooks Online.

Just keep me posted in the comments below if there's anything else you need further assistance with when managing Square integrations or payment options. I'll always be available in this thread to keep you going. Keep safe and have a good one!
