Why 80% of Data in Wholesale Sales Remains Untapped

And what revenue potential is already hidden in your ERP system.
In modern wholesale businesses, enormous volumes of data are generated every day. Every order, every price change, and every customer purchase leaves a trace in the ERP system. In theory, this information should be a goldmine for sales.
In practice, however, something different happens. Many companies collect data over years but only use a small portion of it systematically for decision-making.
This gap is clearly visible even among mid-sized companies. A study shows that 82% of German SMEs consider data analytics strategically important, yet 75% do not have a systematic data strategy.
The result is a paradoxical situation: companies have more data than ever before, yet continue to make sales decisions based on the same rules as 20 years ago, often relying heavily on gut feeling.
Especially in wholesale environments with thousands of customers and tens of thousands of products, this unused data foundation can contain enormous opportunities.
Wholesale Is a Data Machine
B2B wholesale is one of the most data-rich industries. Every order, every price negotiation, and every customer relationship is digitally documented.
Typical wholesalers today work with several thousand active customers, tens of thousands of products, and millions of transactions per year.
ERP systems store a wide range of valuable information, including order histories, customer frequency, product combinations, price developments, and seasonal demand patterns. At first glance, this may sound unremarkable—but these data have significant advantages.
They are generated automatically in daily operations. They do not need to be collected manually, they already exist. They are also highly reliable and up to date. So, the problem is not a lack of data. The problem is how it is used.
Why So Much Sales Data Remains Unused and Why 80 %?
In wholesale, one number appears again and again: 80. It comes from the well-known Pareto principle, which states that roughly 80% of results are often driven by 20% of causes. This pattern can be observed in many economic contexts.
Our own analyses of sales data in wholesale show a similar picture. Not exactly down to the percentage, but broadly speaking, many wholesalers generate around 80% of their revenue from about 20% of their customers.
These are the classic A-customers. They order regularly, generate high revenue, and are very well known to the sales team. Accordingly, they receive a great deal of attention. Field sales teams know their contacts, understand what they buy, and usually notice immediately when something changes.
The real problem, therefore, often does not lie with these top customers. It lies with the remaining 80 %. This large group consists of many smaller customers who order irregularly, purchase only specific product categories, or whose potential has not yet been fully developed. For sales teams, they are difficult to keep track of in day-to-day operations. A single sales representative often manages several hundred customers at the same time, making it nearly impossible to monitor every order history.
This is where a major data problem emerges. The information is actually available. ERP systems make it possible to see which products these customers buy, which ones they have never ordered, and how their purchasing behavior changes over time. However, this data is rarely analyzed systematically.
Instead, sales teams understandably focus on their most important customers. The remaining 80 % are easily overlooked in daily business. Yet this is precisely where significant growth potential often lies.
In addition to this natural prioritization, other factors also play a role. The volume of data in wholesale is simply very large. Thousands of customers, tens of thousands of products, and years of order history create a level of complexity that is difficult to manage using traditional spreadsheet analysis.
Moreover, sales staff have limited time for data analysis in their daily work. Customer meetings, quotations, and operational tasks take priority.
The result is a paradox: wholesalers possess vast amounts of valuable sales data—but a large share of insights remains hidden within the ERP system.
The Hidden Revenue Potential in ERP Data
Within this valuable ERP data, patterns can be identified that are easily overlooked in day-to-day operations.
A classic example is cross-selling relationships between products. Customers who buy product A often also purchase product B. Such relationships are difficult for individual sales representatives to detect, as they only become visible across thousands of transactions.
Another example is gradual customer churn. Often, a customer’s order volume declines over several months before they stop buying altogether. This trend is clearly visible in the sales data but is often recognized too late in practice.
There are also many interesting patterns in pricing. ERP data can provide insights into whether prices for certain customers or products are aligned with the market. They can also reveal the actual price sensitivity of individual customers. In some cases, inconsistencies become apparent. For example, when similar customers pay very different prices for the same product, or when pricing structures have evolved historically and no longer match current market conditions. These patterns are difficult to detect in daily operations but become visible in the data.
From Data to Decisions
The key difference between data-rich and data-driven companies lies in their ability to translate data into concrete decisions.
Many companies create reports and dashboards, but these often remain unused. In practice, a large share of reports provides little real value for decision-making.
Real value is created only when data is actively integrated into the sales process and used to drive decisions.
This means, for example: a sales team identifies at-risk customers early. An account manager receives concrete insights into cross-selling opportunities and proactively offers relevant products. An inside sales representative does not rely on blanket discounts but makes pricing decisions based on data about price sensitivity, demand, and customer behavior.
In other words, data evolves from a passive archive into an active decision-making system.

Why 80% of Data in Wholesale Sales Remains Untapped – Conclusion
Today, many wholesalers are sitting on a surprisingly valuable data asset. ERP systems contain years of order histories, pricing developments, and customer behavior data. Yet a large portion of this information is hardly used systematically in day-to-day sales operations.
This is not because sales organizations are ineffective. It is because the volume of data has grown so large that it can no longer be fully managed using traditional methods.
However, significant potential lies beyond the well-known A-customers. The data from the many smaller customers often reveals cross-selling opportunities, shifts in purchasing behavior, and insights into market-appropriate pricing.
Companies that begin to systematically analyze this information gain a clear advantage. They understand their customers better, apply more differentiated pricing, and identify opportunities earlier.
The key question is no longer whether enough data is available. The more important question is: Are you using the knowledge already embedded in your ERP system?
