A balanced product mix starts with what the market is actually buying—not what the plant can produce most easily. Compare sales by product size and grade with customer feedback, stock levels, and the time each product spends in inventory. Keep dependable, high-demand products available, but avoid building excess stock of slower-moving material.
Trial changes in controlled quantities. Track whether demand holds, then adjust the production plan and replenishment to reflect customer needs, plant capability, and delivery lead times. A short-term spike may not justify a lasting change, so check the trend against order history before shifting the mix. When reviewing stockpiles or plant equipment, follow site procedures and isolate equipment before inspection or maintenance.
Track Sales to Identify High- and Low-Demand Products

Track sales by product over consistent time periods to identify what customers buy regularly and what sits in inventory. Compare unit sales, revenue, and sell-through rates week to week or season to season.
Account for promotions, stockouts, and changes in operating schedules; otherwise, the numbers can point you in the wrong direction.
Rank products by sales velocity and margin, then group them as fast, steady, or slow movers. Use those patterns to set reorder points that reflect supplier lead times and demand variability.
For quarry and plant operations, consider how parts and consumables support equipment uptime: a slow-moving item may still be critical if running out could stop production.
Update forecasts as sales trends change, and review unusual results regularly. Adjust purchasing quantities to limit excess stock without risking avoidable downtime or missed sales.
Before checking inventory or handling parts around operating equipment, follow site lockout procedures and use the required personal protective equipment.
Use Customer Feedback to Refine Your Product Mix
Sales data shows what customers buy. Direct feedback can help explain why they choose a product and what they can’t find. Ask focused questions through surveys, reviews, support calls, and follow-up messages. Record responses by product, sales channel, and customer type. Group recurring comments into practical themes, such as missing features, sizing problems, or price concerns.
Compare feedback with sales patterns before making changes. A request from one customer may not reflect wider demand. Look for differences among new and returning customers, regions, and buying occasions. Use those signals to adjust product features or assortment priorities, then track sales and feedback to see whether the change meets customer needs.
As with any product change, confirm that the product remains suitable for its intended use and operating conditions.
Balance Your Product Mix With Bestsellers and Newcomers
Keep proven bestsellers in your product mix while testing new options in controlled quantities. Track sales velocity, gross margin, return rate, and repeat purchases using the same measures for every item.
Segment customers to see who prefers established products and who’s open to trying something new. Review competitors’ assortments to identify gaps, but don’t add a product just because a competitor carries it.
Set aside a defined share of shelf space or purchasing budget for new products. Before each test, set clear performance thresholds and a review date.
Keep products that meet your targets and discontinue those that don’t. This approach protects dependable revenue while giving you practical evidence about emerging demand.
Adjust Inventory and Promotions When Demand Shifts
When demand shifts, adjust reorder quantities and promotion timing based on recent sales, stock on hand, and supplier lead times.
Compare weekly sales with forecasts to spot products gaining or losing momentum. Replenish rising products as needed, but check storage capacity and cash flow before increasing orders. Reduce purchases of slower-moving items, and promote surplus stock before it becomes harder to sell.
Use pricing carefully to clear excess inventory or respond to competitor changes without giving away margin unnecessarily. Track conversions, units sold, and gross margin during each campaign. Stop or revise offers that miss your targets.
Share updated forecasts with suppliers early to discuss lead times and flexible order quantities. As on a crushing or screening job, sound decisions start with current operating data—not assumptions.
Conclusion
Balance your product mix by tracking sales, listening to customers, and protecting proven bestsellers while testing new products carefully. Use demand data and supplier lead times to adjust stock before shortages disrupt sales or excess inventory ties up cash.
When demand shifts, respond with targeted promotions, sensible pricing, and timely reorders. Review results regularly, compare performance across products, and adjust your assortment based on what customers are actually buying. In crushing and screening, the same principle applies to wear parts and other supplies: stock what your operation uses reliably, and test alternatives before committing to larger orders.
