Supermarket stock and revenue

Every till writes to the same stock figure, so the shelf count and the sales figure cannot drift apart the way they do when the two are kept in separate books. The owner opens one screen at the end of the day and sees takings per branch, per till and per hour.

Features

• Barcode till with an offline fallback that reconciles when the line returns
• One stock figure shared by every till and every branch
• Purchase orders raised from real sales history rather than from a guess
• Stocktakes taken while the shop is open, reconciled against sales during the count
• Expiry and batch tracking for perishables, with a shelf-life warning
• Daily takings broken down by branch, till, hour and payment method
• Margin per product and per category, not just turnover
• A shrinkage report comparing counted stock against what should be there

Counting is the hard part. A stocktake is a claim about a moment rather than a freeze, so the system reconciles it against whatever sold while the counting was going on.
