What evidence would show that a price increase worked?

Evidence that a price increase worked starts with matched prices after discounts, credits and rebates. Revenue growth alone cannot separate price from volume, mix or changing scope. A commercial review must also examine customer response and costs.

Define what worked means before the increase

Record the affected customers, products and period. Name the planned net price and any approved exceptions. Set a review date and decision owner. State the conditions that would trigger another decision.

A plan can retain its intended prices while losing profitable volume. Revenue can also rise while net prices fall. Choose measures that distinguish these outcomes before reading the result.

Keep the evidence levels separate

The levels answer different questions. An announcement supplies a target, while invoice records show implementation. Neither establishes how much of a profit movement the increase caused.

Four cases, four checks

These are selected readings of existing public-record cases. The companies are not ranked or presented as peers. Their public disclosures do not expose every internal check.

Domino’s: distinguish the pricing approach from its application

The selected Domino’s record discusses pricing and promotions across several markets. The case separates stated rules from evidence about their application. A published approach cannot establish the outcome of every promotion or store decision.

For your business, keep the intended offer beside observed invoices and channel checks. Specify the market and dates. Avoid extending a local trial’s finding beyond the customers or products tested.

Caroma’s owner GWA: distinguish price and mix from retained prices

GWA’s selected disclosures discuss price and mix together. That combined description does not isolate matched net price changes. Group sales cannot settle the question alone.

For your business, compare the same customer-product lines before and after the change. Record approved discounts and subsequent credits separately. Explain changes in the comparison set before interpreting its average.

Konnect and Artia’s owner Coventry: distinguish sales growth from margin evidence

Coventry’s case examines reported sales alongside gross profit and management explanations. Growth does not establish improved pricing. Mix, input prices and other changes need their own evidence.

For your business, reconcile revenue and gross profit separately. Keep comparable periods and reporting definitions. Attribute management explanations, then identify what transaction records would test them.

Costco: distinguish the effective date from recognised revenue

Costco’s selected fee increase record separates the announced change from later reporting. Accounting timing matters when interpreting the reported result. Renewal measures also have a defined population and period.

For your business, distinguish the effective date from billing and recognition dates. Check the population behind customer response measures. A later revenue result is not automatically a clean test of the fee change.

Bring a reconciled bridge to the review

Start with the announcement and remove exemptions and timing effects. Compare the remaining target with matched fully net prices. Distinguish approved discounts from unapproved differences. Report any unexplained residual rather than assigning it to price.

Next examine volume and customer losses against the stated comparison. Include product and customer mix changes. Add cost movements before judging contribution. Seasonal changes and wider demand can limit causal conclusions.

No single public case supplies a benchmark for your business. Missing public evidence also says nothing about whether a company performed an internal check. Use these cases to sharpen questions, then answer them with your own records.

Work through the checks

• Inspect the public-record reader.
• Follow one invented increase through all stages.
• Make a pricing decision sheet.
• Measure matched price realisation.
