# Forecasting
> Predict demand and plan restocking
Stockful uses your sales history to predict future demand. Forecasting is available on all plans.
Forecasting uses the 30 days of sales history synced during setup, so predictions are available as soon as your initial sync completes. Accuracy improves over time as more data accumulates.
## What you get
For each variant at each location:
* **Velocity** - how many units sell per day
* **Days of supply** - how long current stock will last at the current sales rate
* **Projected stockout date** - when inventory will run out if nothing changes
* **Reorder point** - when you should place a reorder to avoid running out (accounts for lead time and safety stock)
* **Recommended order quantity** - how much to order based on your restock strategy
* **Sell-through rate** - what percentage of inventory has sold over the last 30 days
* **ABC classification** - whether a SKU is an A (top revenue), B, or C tier item
## Where forecasts appear
* **Inventory list** - sortable columns for days of supply, velocity, reorder point, projected stockout, and stock status
* **Inventory detail page** - full breakdown of forecast metrics for a variant at a location
* **Reorder Recommendations report** - items that should be reordered based on velocity and lead time
* **ABC Analysis report** - revenue-based classification into A, B, and C tiers
## Global settings
Configure defaults for all SKUs in **Settings → Forecasting**. These apply to every variant unless overridden at the SKU level.
### Replenishment
| Setting | What it controls |
| ---------------- | ---------------------------------------------------------------------------------------------------------------------------------- |
| **Lead time** | Days it takes to receive stock from your supplier (0–365, default 7). Longer lead time means earlier reorder recommendations. |
| **Safety stock** | Extra days of buffer stock to keep on hand beyond lead time (0–365, default 3). Protects against demand spikes or shipping delays. |
### Velocity calculation
| Setting | What it controls |
| ------------------- | ------------------------------------------------------------------------------------------------------------------------------------- |
| **Velocity period** | Days of sales history to use when calculating how fast items sell (7–365, default 30). A longer period smooths out short-term spikes. |
### Restock strategy
| Setting | What it controls |
| --------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Restock-to days** | How many days of supply you want after restocking (1–365, default 30). Higher values mean larger, less frequent orders. |
| **Demand adjustment** | A percentage modifier applied to velocity (-100% to +500%). Use this to account for anticipated seasonal changes - for example, +50% ahead of a busy period. Leave blank for no adjustment. |
| **Sales grouping** | How velocity is calculated for multi-location stores. **Per location** (default) calculates velocity separately at each location. **Combined** aggregates sales across all locations before calculating - useful when stock is fulfilled from a central warehouse. |
When in doubt, set a slightly longer lead time than your actual average. It's better to reorder a few days early than to run out waiting for a shipment.
## SKU-level overrides
Not every product has the same supply chain. From **Settings → Forecasting**, click **SKU overrides** to customise settings per variant.
Each variant can override:
| Override | What it does |
| ------------------------------ | ------------------------------------------------------------------ |
| **Lead time** | Supplier-specific lead time for this SKU |
| **Safety stock** | Custom buffer for high-value or volatile items |
| **Low stock threshold (days)** | Override the global days-of-cover low-stock threshold for this SKU |
| **Restock-to days** | Custom restock target for this SKU |
| **Demand adjustment** | SKU-specific seasonal or promotional adjustment |
Leave a field blank to inherit the global default. The override table shows the inherited default value as a placeholder so you can see what each SKU will use.
You can search by product name or SKU, and reset individual overrides back to defaults.
### AI-suggested thresholds
On the SKU overrides page, click **Suggest with AI** to have Stockful's assistant recommend values for lead time, safety stock, low-stock threshold, and restock-to days. Suggestions are based on each SKU's actual sales history, variability, and supplier link. Each suggested field comes with a one-sentence explanation; you can apply suggestions individually or all at once. Bulk mode runs across many selected SKUs; the same suggestion is also available in the inventory detail modal for single-SKU tuning.
## Low-stock threshold
The low-stock alert fires when a SKU is projected to run out within **X days** at its current sales velocity (default 7). Because it's days-of-cover rather than a fixed unit count, the same threshold works for slow-movers and fast-movers without re-tuning per SKU.
### Units floor (for new SKUs)
Brand-new SKUs have no velocity history yet, so days-of-cover can't be computed. For those, Stockful falls back to a **units floor** - alert when stock drops to or below this many units (default 5). The floor only matters until the SKU has accumulated enough sales history; after that, the days-of-cover comparison takes over automatically.
Both settings live under **Settings → Tracking**.
### Settings hierarchy
When calculating forecasts, Stockful resolves each setting in order:
1. **SKU override** - if set on the variant, use it
2. **Supplier default** - if the variant is linked to a supplier with a default lead time, use that
3. **Global default** - the value from Settings → Forecasting
This lets you set sensible defaults globally, override at the supplier level for lead times, and fine-tune individual SKUs where needed.
