Vendor (Specific) purchases Report by years (All) broken out by year

Hello there, @tj1953.

When pulling up a Purchases by Vendor Summary report, you can customize the reporting period as well as the columns to have a Previous Year, Year-To-Date, or Previous Period. However, running the report you need that's broken out by years is unavailable. In the meantime, you can run the report by year, then export them to excel file and merge them to view them as one. 

To export the report, here's how:

1. Open the report you want. 
2. Click the Excel drop-down arrow at the top of the report.
3. Select whether you want to create a new worksheet or use the report data to update or replace an existing worksheet.

See this article for more information about this process: Export reports as Excel workbooks in QuickBooks Desktop.

On the other hand, if you want to have a more detailed version of the purchases by vendor summary report, you can pull up the Purchases by Vendor Detail report. 

For additional reference, here's a great resource about running vendor reports and how you can customize them: Customize vendor reports.
