The operational problem
Static thresholds become stale
A threshold entered once does not respond when sales velocity changes. It can also become unreliable when supplier delivery time or the desired safety buffer changes.
Automating the calculation makes the threshold responsive while keeping every input visible and editable.
The workflow
How automatic reorder points work
- 1Supremo calculates average daily sales from the last 30 days of Shopify orders.
- 2The rate is multiplied by the supplier lead time stored for the product.
- 3Safety stock, configured in days, is converted to units and added.
- 4The threshold is recalculated hourly and compared with current inventory.
What Supremo provides
Specific capabilities for this job
- Formula: average daily sales times lead time, plus safety stock.
- Thirty-day Shopify sales window for automatic velocity.
- Hourly recalculation.
- Safety stock entered as days and converted to units.
- Manual override when future demand needs business context.
- Draft PO creation when configured thresholds are met.
Fit boundary: This is a transparent rules-based calculation, not machine-learning demand forecasting. It does not automatically predict promotions, trends, or seasonal events.
Worked reorder-point example
Average daily sales are eight units, lead time is seven days, and the safety buffer is three days of demand. Lead-time demand is 56 units and safety stock is 24 units, producing an 80-unit reorder point.
