Customer & product analysis beyond traditional 80/20

See what really matters in your business.

eightytwentyplus turns ordinary customer and product transaction data into clear evidence about concentration, context, dependency and complexity — so management can see what deserves deeper investigation.

No account required to start. Your Free Diagnostic runs locally in your browser and analyses the complete accepted dataset rather than a commercial sample.

80/20 is only the beginning.

Most businesses can see what sells. Far fewer can see what actually matters.

Traditional 80/20 and ABC analysis show where revenue is concentrated. eightytwentyplus adds the relationships and operating context needed before management decides what to do.

The Four-Lens Framework

Four questions. One transparent evidence base.

Concentration

Where does the business really make its money?

Analyse customer and product concentration, ABC classes, revenue, quantity and margin.

Context

What changes when relationships are considered?

See Product × Customer mix, category position, location and period context.

Dependency

Where does one relationship matter disproportionately?

Identify products or customers relying heavily on a single counterpart.

Complexity

Where is activity disproportionate to value?

Compare Order Share with Revenue Share where Order ID is available.
