When to kill a product: the analytics of sunsetting

Killing products is harder than launching them

Every product in your catalog once seemed like a good idea. But markets change, trends fade, and some products simply stop earning their place. Keeping underperformers drains resources, clutters your store, and distracts from winners. The analytics of sunsetting helps you identify candidates, make confident decisions, and manage the transition without damaging your business.

Signs a product should be evaluated for sunsetting

Triggers to start the analysis.

Sales decline over time:

Consistent downward trend over 6-12 months. Not a seasonal dip but sustained decline.

Negative contribution margin:

Product loses money after all variable costs. Every sale makes you poorer.

Disproportionate operational burden:

High return rates, frequent customer complaints, or complex fulfillment. The product costs more than revenue suggests.

Opportunity cost:

Inventory capital, catalog space, and management attention tied up in underperformers could be deployed better elsewhere.

Sales velocity analysis

Understand the sales trajectory.

Units per month trend:

Chart monthly units sold over 12-24 months. Is decline accelerating, steady, or stabilizing?

Revenue contribution:

What percentage of total revenue does this product represent? Declining share indicates relative underperformance.

Comparison to category:

Is the whole category declining or just this product? Category decline might be market-wide; product-specific decline is your problem.

Seasonality check:

Is apparent decline actually seasonal? Compare same periods year-over-year before concluding decline is real.

Profitability analysis

Does the product actually make money?

Gross margin:

Revenue minus product cost. Is basic margin healthy?

Contribution margin:

After all variable costs including shipping, packaging, payment processing, and returns. True profitability per unit.

Fully loaded cost:

If you allocate marketing, storage, and overhead, does the product still contribute? Some products look profitable until you add indirect costs.

Trend direction:

Are margins improving or declining? Declining margins accelerate the case for sunsetting.

Operational burden assessment

Hidden costs beyond the numbers.

Return rate:

Products with high return rates cost more than revenue suggests. Returns consume fulfillment, customer service, and inventory resources.

Customer service load:

Does this product generate disproportionate support tickets? Complex products or quality issues create hidden costs.

Fulfillment complexity:

Special handling, fragile packaging, or dimensional challenges. Some products cost more to ship than others.

Inventory management:

Multiple variants, slow turnover, or storage challenges. Inventory carrying costs add up.

Customer impact analysis

Who buys this product and what happens if it disappears?

Customer profile:

Who buys this product? Are they valuable customers who buy other things, or one-time buyers?

Cross-sell relationship:

Do customers buy this product alongside others? Removing it might affect basket composition.

Loyalty impact:

Are repeat customers attached to this product? Discontinuation might upset valuable relationships.

Substitution options:

Do you have alternatives customers could buy instead? Easy substitution reduces discontinuation impact.

Market context

External factors affecting the decision.

Market trend:

Is the broader market for this product declining? Fighting a dying market rarely makes sense.

Competitive position:

Are competitors doing better with similar products? Your execution might be the problem, not the product category.

Supplier situation:

Is the supplier reliable? Supply chain issues might make the product unsustainable regardless of demand.

Decision framework

Structured approach to the sunset decision.

Clear criteria:

Define thresholds. Products below X margin, Y units per month, or Z return rate are candidates.

Multiple factors:

Don’t decide on single metric. Product might have low sales but high margin, or high sales but terrible returns.

Time horizon:

Is decline likely to continue or stabilize? Give reasonable time for recovery efforts before deciding.

Reversibility:

Can you bring the product back if needed? Lower stakes make decision easier.

Before killing: improvement attempts

Try to save the product first.

Price adjustment:

Would different pricing improve performance? Test before discontinuing.

Marketing refresh:

Has marketing gone stale? New creative or positioning might revive sales.

Product page optimization:

Are images, descriptions, or presentation hurting conversion? Easy fixes first.

Promotion test:

Does discounting move units? If even discounts don’t work, demand has truly disappeared.

Managing the sunset process

How to discontinue gracefully.

Inventory liquidation:

Sell through remaining inventory before announcing discontinuation. Discount progressively to clear stock.

Customer communication:

If the product has loyal buyers, notify them. Offer alternatives or final purchase opportunity.

Timeline planning:

Set end date for sales, support, and returns. Clear timeline prevents lingering costs.

Supplier notification:

Inform suppliers of discontinuation. Honor commitments but stop new orders.

Post-sunset analysis

Learn from the experience.

What happened:

Document why the product failed. Market change, execution issues, or wrong product for your audience?

Warning signs:

What signals appeared early that you missed or ignored? Recognize them faster next time.

Process improvement:

Could you have decided sooner? What would enable faster recognition of failing products?

Building sunset discipline

Make evaluation ongoing, not crisis-driven.

Regular reviews:

Quarterly or semi-annual product portfolio review. Don’t wait for products to become obvious problems.

Automatic triggers:

Set alerts for products hitting warning thresholds. Proactive identification.

Portfolio mindset:

Think of your catalog as a portfolio. Regular pruning keeps it healthy.

Product sunsetting checklist

Evaluate before discontinuing:

Sales velocity trend over 12+ months. Contribution margin after all variable costs. Return rate and customer service burden. Customer profile and cross-sell relationships. Market trend and competitive context. Improvement attempts and results. Inventory liquidation plan. Customer communication strategy. Timeline for complete discontinuation. Post-mortem documentation.

Killing products feels like admitting failure. But keeping failing products is the real failure—it ties up resources that could support winners. Data-driven sunsetting keeps your catalog healthy and your business focused on what actually works.
