How GP is calculated
For each product, StockLens uses the most recent supplier cost (from imported invoices), recipe yield and average net selling price (from EPOS imports). The result is a current, accurate GP figure with no spreadsheet involved.
Catching margin erosion early
Supplier price increases erode margin invisibly. StockLens flags products whose GP has dropped below your target, so you can re-price or renegotiate before it hits the P&L.
GP at the category and venue level
Roll GP up by category (spirits, wine, draught, food) and by venue to spot which areas of the business are performing and which need attention.
