Stock Control’s forecasting decides when a variant becomes Reorder Now. Out of the box it uses a simple 7-day threshold, but you can switch to Advanced mode for per-variant and per-supplier accuracy driven by real lead times.
Basic Mode (Default)
Every variant uses a fixed 7-day reorder threshold. If current stock covers fewer than 7 days at the current velocity, it shows up as Reorder Now.
This is simple, predictable, and good enough when you have short, consistent lead times and a small supplier base. No setup required.
Advanced Mode
Reorder point = lead time (days) + safety stock (days).
Lead time is how long it takes for stock to arrive after you place an order
Safety stock is the buffer you want on top of lead time, to absorb demand spikes or delivery delays
Example: a variant with a 14-day lead time and 7 days of safety stock has a 21-day reorder point. Once days of stock falls below 21, it becomes Reorder Now.
The Cascade
Advanced mode looks up lead time and safety stock in this order, stopping at the first one that has a value set:
Variant/supplier override — if a variant is linked to a primary supplier, any per-row overrides set on that link win
Supplier default — the lead time and safety stock you’ve set on the supplier itself
Variant manufacturing override — for variants you manufacture yourself with no supplier, the values set on the variant
Account default — the store-wide fallback set in Settings
This means you can set sensible defaults once, then only tweak variants that are unusual.
Where to Configure
Settings > Forecasting
Pick the mode (Basic or Advanced)
Set account-wide default lead time and safety stock (used as the fallback)
Suppliers > (pick a supplier)
Set a supplier-wide lead time and safety stock (overrides the account default for variants linked to this supplier)
Suppliers > (pick a supplier) > variants
Per-variant overrides on the supplier link (overrides the supplier default for that specific variant)
Inventory page > variant drawer > manufacturing tab
For variants without a supplier, set per-variant lead time and safety stock directly
When to Switch from Basic to Advanced
Stay on Basic if:
You replenish everything from one or two suppliers on similar lead times
Your sales volume is steady enough that 7 days is a reasonable buffer
You haven’t added supplier data yet
Move to Advanced when:
Different suppliers take very different lead times (2 days vs 6 weeks)
Some variants need more safety stock than others (e.g. volatile sellers, promo SKUs)
You’re tired of seeing Reorder Now either too early or too late
The switch is non-destructive — you can toggle back to Basic at any time and keep your supplier data.
Seeing Forecasting in Action
On the Inventory page, the Days of Stock column and the status bucket both respect whichever mode you’re in. Open a variant’s drawer to see the effective reorder point used for that specific row — useful for sanity-checking the cascade.
