You'll find your Profit & Loss report under Accounting > Reports > Summary > Financial > Profit and Loss (New).
We'd recommend you star it, and other favourite reports. This means they'll show up in the Accounting tab.
Your Profit & Loss account (P&L) will show:
Turnover (Sales)
Cost of Sales
Gross Profit
Administrative Costs
Operating Profit (Net Profit)
Profit before and after Tax
Choose the date range you are interested in and compare with previous periods if appropriate.
Use the 'Filter' option to look at one part of your business, e.g. a Department, Region or other category you track. If you're not already tracking, find out more about Tracking Categories / Departments.
If you'll need to look back at this report again and again, Save as a Draft or Published report. (These are available at Accounting > Reports > Draft or Published tab).
Alternatively, Export and select PDF, Excel or Google Sheets.
