Frequently Asked Questions

- Supremo is a complete inventory management platform for Shopify. It helps merchants manage purchase orders, vendors, inventory transfers, stocktakes, multi-location inventory, reorder planning, and inventory reports. Free for up to 100 products and 2,000 variants.
- Does Supremo replace Stocky?
- Stocky stopped operating on August 31, 2026. Shopify says existing installations retain read-only export access for at least 90 days after shutdown, with no exact end date published. Supremo supports Shopify purchase orders, suppliers, reorder points, transfers, stocktakes, reporting, and customer-order fulfillment, but does not offer an automated Stocky import or reproduce every Stocky workflow. Check current plan limits and compare the workflows you need before switching.

- How does Supremo calculate reorder points?
- Supremo uses the formula: daily sales velocity (units sold per day over the past 30 days) x vendor lead time (days) + safety stock buffer.
