See here which reports can help you showing your store's profit!
These reports work in a simple and practical way, allowing you to check the profitability of your store by two different criteria, one being the REVENUE / EXPENSES report and the other by SOLD PRODUCT.
Revenue /Expenses: In this report you can check your store's revenue in a given period, as well as the expenses that were paid. This way, you can have a control over the profit of your business in a broader way. Here is how to generate this report.
By Sold Product: This report will show the profitability of each product that was sold in the selected period. For the system to be able to perform this calculation, it is necessary that the product has a registered COST PRICE (learn more). Not only it will display the total profit information, the profit percentage is also calculated, in which the final profit (net) is compared with the sales turnover (gross revenue). Here is how to create this report.
