Good day, @info-goscription. I'm here to help share information on how to deposit your checks.
You'll have to deposit the check to your bank first and transfer it to your QuickBooks Cash account. You may need to set up an account you already linked for online banking a second time for QuickBooks Cash.
To track the money movement, you can record the deposit in QuickBooks Online (QBO). You'll have to choose the Add funds to this deposit option from the bank deposit window and select checks as the payment method.
Follow these easy steps to get this done right away:
Navigate to the +New button and choose Bank Deposit.
Pick the Account where the funds will be deposited.
In the Received From section, choose where the money is coming from.
Please know that you're always welcome to comment below if you have other concerns or follow-up inquiries about the QBO. I'm just around to help. Take care always, @info-goscription.
