Managing replenishment can be one of the trickiest parts of running a retail business. Order too little, and you risk stockouts. Order too much, and you tie up capital in products that sit in your warehouse. Tightly’s Replenishment Policies and Smart Replenishment work together to keep your inventory balanced and profitable.
Where to Find Replenishment in Tightly
On the left-hand menu, click Replenishment. You’ll see five tabs:
Smart Replenishment – the central hub where all replenishment recommendations are displayed.
Replenishment Policies – where you define the rules that generate recommendations.
Demand Planning – where you can manually adjust demand for upcoming periods.
Events – where you set special scenarios like promotions or seasonal spikes.
Budget – where you control financial limits and spending constraints.
This guide focuses on the first two tabs: Replenishment Policies and Smart Replenishment.
Replenishment Policies
Tightly Default Policy
Every account starts with the Tightly Default Policy. This ensures replenishment recommendations are available immediately, even if you never set up a custom policy.
Here’s how the default logic works:
Sales history requirement: At least 14 days of sales data must be available before a product is eligible for recommendation. (We call this the warm-up period.)
Sales velocity calculation: The product must have at least 31 non-stockout days within the last 180 days for us to calculate a reliable sales velocity.
Composite score: Products are ranked using a profitability + demand score, which decides which ones need replenishment sooner.
👉 Newly added products won’t be recommended until they collect enough sales data.
Creating Custom Replenishment Policies
While the default policy is powerful, you can create custom replenishment policies tailored to your business. When setting up a custom policy, you define:
Replenishment Trigger – When should replenishment happen?
Days of Cover: Maintain a set number of days of inventory on hand.
Safety Stock: Maintain a buffer stock to prevent stockouts.
Reorder Amount – How much to reorder once the trigger is reached?
Tightly Default Quantity: The system’s calculated reorder amount.
Quantity: The amount you want to be recommended each time when the policy is triggered per variant.
MOQ (Minimum Order Quantity): Ensures orders meet supplier requirements.
Custom policies can be applied across all products or targeted to specific products and suppliers.
Smart Replenishment
The Smart Replenishment tab is where all recommendations are displayed. These recommendations come from:
Tightly Default Policy
Any Custom Replenishment Policies you’ve created
So instead of jumping between different policies, you have a single view of all replenishment needs.
What You’ll See
In the Smart Replenishment tab, you’ll see a Products Table with all recommended products. Each row includes:
Product name
Recommended quantity
Policy source (e.g., Tightly Default or a custom policy you created)
“See details” button
Click this to view a breakdown of the recommendation, such as:
Days of cover if you restock now
Supporting calculation details
Incoming Purchase Orders
Planned Events in the near future that the recommended product is included in.
Filtering Recommendations
The table includes a filter panel that allows you to narrow down recommendations by:
Replenishment policy (Default or custom)
Supplier
In stock/on order
Shopify tags
Health status
Many other product attributes
This makes it easy to focus only on the recommendations that matter most at the moment.
Acting on Recommendations
From Smart Replenishment, you can move directly toward replenishing stock:
Select products using the checkboxes.
Click Add to Basket.
The products are added with the recommended quantities.
You can always adjust these quantities later in the basket before creating a Purchase Order.
In summary:
Replenishment Policies (Tightly Default or the custom ones) generate the logic.
Smart Replenishment tab is where you see and act on all recommendations.
Together, they help you stay stocked at the right levels without over-ordering.
