Hi there, sunshine. I'll be here to ensure you can record your invoice payment to the correct account.
QuickBooks Online (QBO) Sole Trader is a simpler version of QuickBooks for small businesses or self-employed people. It has fewer account options to make it easier to use. Since it doesn’t include predefined bank accounts, when you mark an invoice as paid, it may default to Cash. This happens as the system doesn’t know where to assign the payment unless you’ve connected your bank account. Until then, it uses Cash as a placeholder.
With that in mind, ensure your bank account is connected to QuickBooks. Open the Bank transactions section, click Link account from the dropdown menu, and select your bank. Follow the secure steps to connect your account. Please also note that transactions will sync once your bank processes them. If the payment is being deposited into your bank, wait for it to clear before recording it.
Once done, and the payment appears in your bank feed, go to the Invoices menu, select the invoice, and click Record payment. Select your bank from the Deposited to field and follow the steps to match the transactions. If the transaction doesn't appear, the payment may still be processing with your bank. Please wait for it to clear before attempting to link it.
After the transactions are linked, the invoice status will update to Deposited, reflecting that the payment has been recorded in your bank account.
