Thanks for reaching out to us, @A_Hendricks. I'm here to provide some helpful tips to handle your transactions in QuickBooks Online (QBO) without using online banking.
In QBO, you have the option to record Bank Deposits manually, allowing you to post transactions to your real-life bank accounts without connecting to online banking. Doing so allows you to combine multiple entries into a single record to match your actual deposits. Alternatively, you may enter a Check or an Expense and select the bank account you used as a payment method.
However, if you want to keep track of your accounts receivables and payables, you can enter them accordingly as invoices, bills, etc. I'll share these articles for your guide:
You may also save time by adding transactions manually into the account register. It is convenient when you're reviewing your Chart of Accounts and need to make a quick addition.
Moreover, QBO offers several reports to help you obtain an overview of your business, allowing you to see how your sales and expenses are performing.
Keep in touch if you need further guidance in entering transactions in QBO. I'll be more than glad to provide additional assistance. Take care, and have a good one.
