Can I add yearly historical financial statements in QBO from 2021 to 2023? I am starting a client's file in QBO in 2024. I do not have past years detailed transactions.

The best option is to have trial balances for those historical years and import them as JE.

Hi there romina-startupof,

Thanks for reaching out about your prior history. QuickBooks Online is a great tool able to assist you with keeping track of your sales and expenses so you know the profit of your company. I can provide some information about entering these transactions.

To enter it all at once, you can create or import a journal entry as mentioned by 4Gal. To create a Journal entry, go to +New, then Journal entry. To import one instead, you can follow the steps in this article.

If you have any other questions, feel free to reach out here.
