Every building materials distributor faces the same balancing act: carry too much inventory, and capital gets locked up in slow-moving stock; carry too little, and you miss sales or delay jobsites. Thats why tracking your stock-to-sales ratio in real time within ERP is no longer optionalits essential.
This KPI measures how much inventory you have on hand relative to what you’re selling. When embedded in ERP dashboards, it becomes a powerful lever for optimizing purchasing, improving cash flow, and aligning inventory with true market demand.
Why the Stock-to-Sales Ratio Matters
Lets say youre carrying 200,000 square feet of fiber cement board but only selling 25,000 per week. Thats eight weeks of supplyexcessive if lead times are short, dangerous if demand drops. The stock-to-sales ratio gives you immediate visibility into:
Overstocked SKUs draining cash
Understocked materials causing missed orders
Seasonal mismatch between inventory and demand
Branch-level inventory discrepancies across your network
Tracking this ratio in real time, through ERP, gives every departmentfrom procurement to sales to financea shared view of whats moving and whats sitting.
Key Features of ERP-Based Stock-to-Sales Tracking
Live SKU-Level Reporting
ERP systems break down ratios by product, category, or locationallowing you to see that pressure-treated lumber is at 1.3x target, while acoustical ceiling tile is at 0.6x.
Automated Ratio Calculations
No spreadsheets. ERP calculates the ratio daily or weekly using real-time inventory levels and trailing sales data (e.g., 30-, 60-, or 90-day run rates).
Target Ranges by Product Class
Set acceptable ratios per material type. High-turnover products like drywall may have a 1.2x target; slower-moving SKUs like rebar or sealants might tolerate 2.5x.
Alerts for Over and Under Thresholds
ERP flags items falling outside ideal rangestriggering reorder or markdown actions automatically.
Trend Dashboards for Procurement
Track ratio movement over time to identify demand shifts or seasonal peaks (e.g., insulation demand drop-off after Q1).
Branch Comparisons
For multi-location distributors, ERP reveals which branches are overstocking or understocking compared to sales velocity.
Business Impact for Distributors
Improve cash flow by reducing unnecessary inventory holding
Boost fill rate with timely reorders driven by true sales velocity
Avoid deadstock write-offs through early visibility and markdown strategy
Align procurement with demand patterns, not gut feel
ERP doesnt just tell you whats in stockit shows whether that stock makes sense.
