I have a suggestion. Under Econoview, you currently have Sales, Ongoing expences and Resources.
My suggestion is that they be changed to Sales, Cost of Sales (CoS) and Operating Expenses. Cost of Sales can also be Cost of Goods Sold. These are the terms currently used. Also, CoS normally follow Sales in your P&L statement. Followed by Operating expenses. After Operating Expenses, you can have non operating income/expenses like interest, sale of equipment.
Here is an example I found of Google that gives a quick explanation. You can also search for “IAS 1” (International Accounting Standard) online for the full guidelines of a P&L.
