Hey there, @ddddddd.
Let me help view your last 3 years' worth of data in the profit and loss report. This way, you can review your income, expenses, and net income for the last three years.
All you have to do is to customize its report period by year and print each data. This way, you can easily compare them together with your accountant.
Let me show you how:
- Go to Reports and open the Profit and Loss report.
- Select Custom in the Report period drop-down list.
- Change the date range and select Run report.
- Click the Print icon to print.

Repeat the steps until you get all of the necessary information. Then, you can now compare them.
In addition, you can customize this report to have a better view of your business.
Should you have any follow-up questions or concerns, don't hesitate to post again here in the Community or leave a comment on this thread. Take care and have a good one.
