Understanding suggested reorder quantities

Suggested reorder quantities help you decide how much stock to order to reach your target inventory level after restocking.

The way this value is calculated depends on whether you’re using Classic Mode or Smart Mode.

Classic Mode

In Classic Mode, you set your Restock to levels in quantities.

These are configured per notification under the Products and thresholds page.

You can:

• Set a Default restock to value that applies to all included products.
• Override the Restock to level for specific products or variants (depending on your plan).

This number represents the target inventory quantity you want to have after restocking.

✏️ Suggested reorder quantity formula

Restock to − Available inventory

Example

If your Restock to value is 100 units, and your Available inventory is 35 units:

→ Suggested reorder qty = 65 units

When you restock 65 units, your total stock will reach the 100-unit target you’ve set.

Smart Mode

In Smart Mode, Stockie automatically calculates reorder quantities using your sales velocity and forecast settings.

Instead of setting a quantity, you set a Restock to value in days of inventory cover — this represents how many days of stock you’d like to have after your next order arrives.

You can configure this on the Inventory Forecasting settings page:

Forecasting → Manage settings

There you can:

• Set default restock settings that apply across your store.
• Override specific products or variants if needed.

How it’s calculated

Smart Mode converts your “days of cover” target into units, based on your average daily sales.

Then it adds lead time demand (the quantity expected to sell while your next order is in transit).

Finally, it subtracts your current available inventory to determine how much to reorder.

✏️ Suggested reorder quantity formula

(Target inventory + Lead time demand) − Available inventory

Where:

• Target inventory = Restock to (days) × Average daily qty sold
• Lead time demand = Lead time × Average daily qty sold
• Available inventory = Current available stock

The quantity is always rounded up to the nearest whole unit and will never be negative.

Example

Let’s say:

• Average daily sales = 5 units/day
• Restock to = 30 days
• Lead time = 10 days
• Available inventory = 60 units

1️⃣ Target inventory = 30 × 5 = 150 units

2️⃣ Lead time demand = 10 × 5 = 50 units

3️⃣ Suggested reorder qty = (150 + 50) − 60 = 140 units

That means ordering 140 units will bring your total back up to your 30-day inventory target once your order arrives.
