The operational problem
Reorder timing is different for every product
A fast seller with a slow supplier needs an earlier trigger than a slow seller available from a local supplier.
A fixed store-wide low-stock number ignores these differences and can create both stockouts and unnecessary purchasing.
The workflow
Calculate the trigger for each SKU
- 1Measure average daily sales from recent Shopify orders.
- 2Record the supplier lead time for the product.
- 3Choose a safety-stock buffer in days.
- 4Compare current available inventory with the resulting reorder point.
What Supremo provides
Specific capabilities for this job
- Automatic or manual reorder points per SKU.
- Transparent formula with visible inputs.
- Sales velocity based on actual Shopify orders.
- Supplier-specific lead time.
- Safety stock expressed as a practical number of demand days.
- Replenishment reports and draft purchase orders.
Fit boundary: The calculation is only as useful as its inputs. Merchants should review supplier lead times, unusual sales periods, and stock accuracy.
Example: two products need different triggers
Two products may each have 50 units available. One sells one unit per day and arrives in five days. The other sells ten units per day and takes two weeks to arrive. The second product is much more urgent even though the current stock count is identical.
