Quality Cost & Returns | Valverus

Quality Cost / Returns / Customer Complaints

Every return has a cost you’re not tracking.

Quick answer Cost of poor quality (COPQ) includes scrap, rework, warranty, returns, and the harder to quantify cost of customer trust. It is almost always higher than what shows up on the P&L directly. Quality issues persist because defects and variation are treated as isolated incidents rather than statistical patterns, and because a genuine continuous improvement culture is missing.

The challenge

Quality issues, complaints, and warranty costs don’t just hit the P&L where you expect them to-they erode trust in the market long after the defect itself is fixed.

Root causes

Defects and variation get treated as isolated incidents instead of statistical patterns. Certifications exist, but a genuine continuous improvement culture doesn’t. No one has calculated the true, all-in cost of poor quality, so the business case for fixing it never gets made.

Our approach

Valverus improves quality performance and reduces total cost of quality by deploying targeted defect and interval variation reduction improvements that eliminate scrap at the source, thus drastically reducing warranty and return liabilities. We also deploy quality systems, continuous improvement programs, and support the development of company-wide, employee-engaged quality cultures.

Cost of poor quality (COPQ) can consume 15–20% of annual revenue for manufacturers. External failure costs, the ones that reach the customer, like recalls and warranty claims, can run 10 to 100 times higher per defect than catching the same issue internally.

Frequently asked questions

CEOHow do repeated quality issues damage market reputation long after the defect itself is fixed? +

Customers and channel partners remember failure patterns longer than the specific defect. Repeated issues erode trust in a way that a single corrective action can’t undo quickly.

CFOHow much is poor quality really costing us in warranty, returns, and rework? +

Cost of poor quality typically runs 4–15% of revenue, and most organizations only track the direct warranty and return line items, missing scrap, rework labor, and expedite costs hidden elsewhere in the P&L.

COO / Supply Chain LeaderHow do you reduce the cost of quality without slowing down delivery? +

Targeted defect and variation reduction at the source, rather than added inspection downstream, improves both quality and throughput at the same time, instead of trading one for the other.

PE Managing PartnerHow does cost of quality affect EBITDA multiples at exit? +

Unresolved quality liabilities are a common diligence flag. Buyers discount for the risk of undisclosed warranty exposure, which directly compresses achievable multiples.

What is cost of poor quality (COPQ) and how is it calculated? +

COPQ sums the cost of prevention, appraisal, and both internal and external failure: scrap, rework, warranty, returns, and lost customer trust. Most companies only track external failure costs, understating the true number significantly.

What’s the difference between a quality management system and a continuous improvement culture? +

A quality management system is the documented process and certification (like ISO); a continuous improvement culture is whether employees at every level actually catch and fix problems day to day. Certifications alone don’t guarantee the culture exists.
