Where does the business really make its money?
Analyse customer and product concentration, ABC classes, revenue, quantity and margin.
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.
What changes when relationships are considered?
See Product × Customer mix, category position, location and period context.
Where does one relationship matter disproportionately?
Identify products or customers relying heavily on a single counterpart.
Where is activity disproportionate to value?
Compare Order Share with Revenue Share where Order ID is available.
