Welcome to the Community, Oliver. It's our pleasure to help you with managing your concern. We'll ensure to share some insights to help you manage your transactions to ensure the accuracy of your business.
We understand the importance of keeping your accounts accurate and your past transactions in sync with our program. In this case, we can enter historical information in QuickBooks Online (QBO). You'll want to enter past sales and Accounts Receivable (A/R) transactions, as well as past supplier transactions, before entering any past cheque or bank transactions. QBO updates your bank balance as you enter payments received from customers and payments to suppliers.
You can enter past sales and A/R transactions in two ways for accurate reporting. These methods are Chronologically, in which you record your charges in order, and In Batches if you don't have the time to enter them in order. See this article for further guidance: Enter historical information in QuickBooks Online. It also includes the steps and insights in recording historical supplier transactions and bank transactions.
