How reorder points are automatically calculated
In Smart Mode, Stockie automatically calculates a reorder point for every product variant using your forecast data.
This reorder point acts as your low-stock threshold, ensuring you reorder early enough for new stock to arrive before running out.
What a reorder point means
A reorder point is the stock level at which Stockie predicts you should place your next order.
When a product’s available inventory is forecasted to fall to (or below) this level, it’s considered ready to reorder.
Products that are expected to reach their reorder point within your notification window (for example, within the next 7 days) will appear in your Smart Mode notifications.
How Stockie calculates reorder points
Stockie’s reorder-point formula combines your expected sales during supplier lead time with your extra buffer (safety stock):
✏️ Reorder-point formula
(Lead time × Sales velocity) + (Safety stock × Sales velocity)
| Input | Description |
|---|---|
| Sales velocity | Average number of units sold per day. Calculated from recent sales history, excluding days when the product was out of stock (unless “Continue selling when out of stock” is enabled in Shopify). |
| Lead time | The number of days it takes for new stock to arrive after placing an order. |
| Safety stock | Extra buffer inventory, expressed in days of cover. Stockie multiplies this by sales velocity to convert it into units. |
💡 Tip: Defining safety stock in days keeps your coverage consistent across different products — e.g., always keeping an extra four days of inventory regardless of sales speed.
Example
Let’s say you sell a product with:
- Sales velocity: 4 units/day
- Lead time: 7 days
- Safety stock: 4 days
Stockie calculates:
Reorder point = (7 × 4) + (4 × 4) = 44 units
That means when your available inventory drops to 44 units or fewer, the product is considered ready to reorder.
If your Smart Mode notification window is 7 days, this product will be included when it’s expected to reach that reorder point within the next seven days.
Why reorder points matter
Reorder points ensure you maintain enough stock to cover both:
- Lead-time demand – what you’ll sell while waiting for new stock to arrive, and
- Safety stock – your buffer to protect against delays or demand spikes.
Without an accurate reorder point, you risk running out before your next delivery — or over-ordering and tying up cash in excess inventory.
How to adjust your reorder points
Because reorder points are automatically calculated, you can influence them by adjusting:
- Sales velocity → determined by your sales look-back period.
- Lead time → set globally, per supplier, or per product.
- Safety stock (days) → defines how much extra coverage you want.
Each time these values change, Stockie recalculates reorder points automatically in the nightly forecast refresh.
