Sell cookies as singles, 6-packs, and 12-packs from one batch of 50. Sell one 6-pack and all variants update instantly. Define shared stock, link variants with consumption ratios, and every sale recalculates and syncs all connected variants in seconds. Works for pack sizes, weight-based products, bundles, and limited editions. No double-deductions during simultaneous orders. Full activity log with before and after quantities.

• Consumption ratios for pack sizes, weight-based products, and bundles
• Updates within seconds of each sale, not on a long polling cycle
• Two orders at the same time? No double-deductions, no overselling
