I've noticed that on the Annual Profit & Loss report item 6810 - Equipment Purchase isn't included.
Do I need to change the item number of Equipment Purchase to something else so that it will show up on the Annual Profit & Loss report? If so, where can I find a list of item numbers that will show up on the report?
It is not showing up on your P&L report because, when you purchase equipment, you are purchasing an asset and have not expensed anything yet. If you run a balance sheet report, you should most likely see it under 'Fixed Assets'.
Income and expense accounts show up on the P&L and asset, liability and equity accounts show up on the balance sheet (what you own vs. what you owe).
You can't just expense equipment without knowing whether or not it is allowed. Some equipment can be expensed immediately and others need to be depreciated (an expense) over time. You should contact a CPA to know for sure.
Allow me to share some insights about running reports in QuickBooks Desktop (QBDT).
In QBDT, you can customize reports base on your preferred data. A possible reason it doesn’t show in your annual profit and loss report is that the item is not yet created within that time frame. Thus, it only shows on your monthly profit and loss report.
You’ll want to ensure the data or information you’re looking for in a report matches the setting you set. For more details about running reports and how to generate it base on your preference, you can check out these articles for guidance:
