The Demand Planning feature in Tightly gives you a clear, SKU-level view of recent sales trends and helps you anticipate future stock needs with confidence.
Overview
Tightly’s Demand Planning tool lets you monitor how products are selling and forecast upcoming demand based on sales velocity. It provides merchants with actionable insights to plan inventory replenishment and avoid both overstocking and stockouts.
The module is designed to make decision-making data-driven by giving full visibility into every product’s recent performance, filtered by product, variant, and location.
With Demand Planning, you can:
View 30-day sales velocity across all variants.
See expected units needed for upcoming months.
Compare forecasted demand against on-hand stock.
Easily filter, group, or search by product or variant.
Identify slow movers or fast sellers for restock or phase-out.
How It Works
What is Demand Planning?
Demand Planning analyzes recent sales velocity (typically the last 30 days) and projects how much inventory you’re likely to need in the upcoming months.
It helps you answer the question: “How many units should I expect to sell next month, and do I have enough stock to meet that?”
Tightly uses this data to support Smart Replenishment and PO decisions — but you can also explore it independently for ad hoc planning and deeper merchandising decisions.
1. Sales Velocity Calculation
Tightly calculates 30-day average daily sales for each product variant.
You’ll see this as “Sales Velocity (Last 30 days)” in units per day.
Variants with zero velocity are typically slow movers or newly launched items.
This metric is the foundation for monthly demand forecasting.
2. Monthly Demand Forecast
Columns like April, May, and so on show forecasted demand per month, based on your sales velocity.
Forecasts are calculated as:
Sales Velocity × Number of Days in Month
This helps you plan replenishment cycles in advance.
Months with “0” indicate either zero historical velocity or insufficient data.
3. Filtering and Grouping
The left-hand panel allows you to:
Filter by product, variant, or collection.
Toggle between “Group by Products” or view each variant individually.
Focus only on modified items or those with sales velocity updates.
This gives you control over what you’re reviewing — whether you’re doing a seasonal planning review or just checking up on your bestsellers.
4. Edit Mode and Forecast Adjustments
Enable Edit Mode (top right) to make manual adjustments to forecasted units.
This is useful for upcoming campaigns, product relaunches, or expected demand spikes.
Edited items are automatically flagged under the “Modified Items” section for easy tracking.
5. Search and Export
Use the top search bar to:
Search by Product Name or Variant ID.
Quickly locate specific SKUs across hundreds of items.
You can also export demand data to CSV for reporting, bulk planning, or sharing with team members.
Using Demand Planning
Access Demand Planning
Log into Tightly.
In the left-hand menu, click on Demand Planning under Replenishment.
Step 1: Filter by Product or Variant
Use the filter panel on the left to narrow your view by:
Products (by name or collection)
Variants (individual SKU sizes/colors)
Sales Velocity (active, slow, or zero)
Toggle “Group by Products” to collapse multiple variants into a single line per product.
Step 2: Review Sales Velocity
Focus on the Sales Velocity (Last 30 Days) column to understand how fast each item is moving.
This tells you which SKUs are in demand and which may need discounting or bundling.
Step 3: Forecast Monthly Needs
Use the monthly columns (e.g. April, May) to:
See forecasted unit demand per month.
Compare against on-hand or incoming stock to assess risk of stockouts.
This is your inventory roadmap.
Step 4: Edit and Refine Forecasts
If you’re preparing for promos, peak season, or expected drops:
Toggle Edit Mode to adjust demand forecasts.
All changes are saved automatically.
Adjusted items appear in the “Modified Items” tab for tracking.
Step 5: Take Action
Once you’ve reviewed demand:
Use this data to inform Smart Replenishment or create custom Replenishment Sets.
Export insights for your buying or merchandising team.
Use zero-velocity data to identify dead stock.
Bottom Line:
Demand Planning in Tightly gives you full visibility into what’s selling and what’s not — helping you take action early and plan smarter.
It’s the foundation for confident, data-driven inventory decisions.
