The quality of your buying decisions — what to order, how much, and when — directly determines your inventory efficiency and cash flow. Integrating data into the process improves accuracy significantly.
Sell-Through Rate as a Buying Signal
Sell-through can help evaluate demand relative to available inventory. Interpret it with seasonality, stockouts, lead times and the planned assortment rather than assigning a universal cut-off.
Days on Hand as a Risk Indicator
Compare days on hand with demand variability, lead times and replenishment plans. A figure that indicates risk for one SKU may be appropriate for another.
Margin by SKU Guides Assortment Decisions
Revenue without margin context is incomplete. Sort your assortment by gross margin dollars and gross margin percentage — these two lenses guide which products deserve investment and which deserve rationalization.
The fix: Calculate sell-through rate and days on hand for your top 20 SKUs this week. Identify your highest risk positions — both stockout and overstock risk. Address those in your next buying cycle.
Start with the decision the buyer needs to make
Buying reports should answer practical questions: how much to reorder, which SKUs to stop, when stock will run out and which supplier delay needs escalation. Avoid dashboards full of metrics with no action attached.
Combine demand, inventory and open supply
Use sellable stock, committed demand, open purchase orders, supplier lead time and recent sales together. Looking at sales velocity alone can create duplicate orders when inventory is already on the way.
Flag exceptions rather than reviewing every SKU equally
Highlight stockout risk, excess weeks of supply, delayed POs, high forecast error and material cost changes. Buyers can spend more time on decisions that change cash or service levels.
Keep assumptions visible
Document safety stock, lead time, promotions and manual forecast adjustments. When the outcome differs from the plan, the team can see whether the assumption or execution was wrong.

Add cash and capacity to the buying view
A mathematically correct reorder can still be a poor decision if cash is constrained or warehouse capacity is full. Include open commitments, payment timing and storage limits in high-value purchase decisions.
Review buyer overrides
When a buyer changes the suggested order quantity, record the reason. Over time, compare those overrides with actual outcomes to see whether the planning logic is missing known events or whether manual adjustments are adding noise.
Create an exception-based buying meeting
Review only SKUs with stockout risk, excess supply, delayed POs, unusual demand or cost changes. This keeps buyers focused on decisions rather than reading every line of an inventory report.
Audit outcomes against the original assumption
When a large order is placed, save the demand, lead-time and safety-stock assumptions used. Compare them later with what happened so the planning model improves over time.
Use aging views for open supply
Flag purchase orders that remain unconfirmed, delayed or partially received. Old open supply can make inventory projections look healthier than reality if the dates are not maintained.
