How to Find Your Fastest Growing Customers
Every business celebrates winning new customers.
But many of the biggest growth opportunities are already sitting in your customer database.
Some customers gradually increase their spending every month.
Others begin purchasing new product ranges.
Some expand into new locations.
Others simply become more loyal over time.
The challenge is recognising these opportunities early enough to build on them.
Most SMEs know who their biggest customers are.
Far fewer know which customers are growing the fastest.
Growth Doesn’t Always Make Headlines
Whether you use Sage 50, Sage 200, Microsoft Dynamics 365 Business Central, Xero, Exchequer, Pegasus Opera, Dynamics NAV, SAP Business One, Brightpearl or another ERP system, your business already records every sale.
The information is there.
The problem is turning it into meaningful insight.
Business owners regularly ask questions like:
- Which customers have increased their spending the most?
- Which customers are growing year-on-year?
- Which customers have doubled their purchasing?
- Which customers have started buying new product ranges?
- Which sectors are growing fastest?
- Which customers deserve more attention from our sales team?
- Which accounts should we be investing in?
These are exactly the questions that help businesses grow revenue more efficiently.
Why Most Businesses Miss Growth Opportunities
Many companies spend significant amounts on lead generation, marketing and prospecting.
At the same time, existing customers quietly increase their spending without anyone noticing.
No congratulations.
No account review.
No additional support.
No attempt to cross-sell.
No effort to strengthen the relationship.
One Sales Director from a manufacturing company told us:
“We spent so much time chasing new customers that we overlooked the ones who were already choosing to spend more with us.”
Excel Makes It Difficult
Identifying growing customers usually involves comparing different reporting periods.
That means exporting customer sales.
Exporting last year’s figures.
Building pivot tables.
Running comparisons.
Highlighting percentage increases.
Producing reports.
Then repeating the process every month.
By the time the report is finished, the sales team has often moved on to something else.
A Real Customer Story
A national wholesaler approached Illuminis Insight Software because they wanted to improve customer retention.
After reviewing their existing reporting, we noticed something unexpected.
While management focused heavily on declining customers, there was almost no visibility of customers who were growing rapidly.
Our consultants recreated their reporting process inside Octelas, introducing live customer growth dashboards.
The business could instantly identify:
- Customers with the highest year-on-year growth.
- Customers increasing monthly spending.
- Customers buying new product ranges.
- Fast-growing accounts by salesperson.
- Growth by region.
- Growth by customer sector.
- Emerging high-value accounts.
Within weeks, the sales team had prioritised visits to their fastest-growing customers.
The result wasn’t just stronger relationships.
It led to additional cross-selling opportunities, larger orders and improved customer retention.
The Sales Director later told us:
“We realised our fastest-growing customers deserved just as much attention as our biggest customers.”
Another Customer Found Hidden Opportunities
A construction supplier believed most of their business growth came from winning new accounts.
After implementing Octelas, they discovered almost 70% of their revenue growth had actually come from existing customers increasing their spending.
That insight completely changed their sales strategy.
Instead of focusing almost exclusively on new business, they invested more time developing relationships with customers who were already growing.
The Managing Director later commented:
“The easiest sales turned out to be with customers who already trusted us.”
Every Business Defines Growth Differently
Some businesses compare this month against last year.
Others analyse rolling twelve-month performance.
Some focus on revenue growth.
Others look at gross profit.
Some monitor customer growth by product group.
Others by branch, region or salesperson.
That’s why Illuminis Insight Software doesn’t provide one-size-fits-all reports.
We begin by understanding how your business measures success.
We review your Excel spreadsheets, management reports and KPIs before recreating the reporting logic inside Octelas.
The result is reporting that reflects the way your business actually works.
More Than Business Intelligence Software
Many SMEs looking for customer growth reporting investigate Microsoft Power BI.
Power BI is excellent for creating dashboards.
But meaningful reporting requires much more than charts.
Someone still needs to understand your business.
Define your KPIs.
Build the calculations.
Maintain the reports.
Support users.
And make ongoing improvements as your reporting evolves.
Without an experienced reporting partner, those responsibilities often become another burden for the business.
A Data Partner That Grows With You
At Illuminis Insight Software, we don’t simply install software.
We become your long-term reporting and data partner.
We understand your business.
We recreate the reports you’ve already built.
We automate the repetitive work.
And we continue developing your reporting as your business grows.

As your business evolves, your reporting evolves too.
Invest More Time in Your Best Opportunities
Your fastest-growing customers are telling you something important.
They’re choosing to spend more with your business.
The earlier you identify them, the easier it becomes to strengthen those relationships and accelerate future growth.
Octelas, developed by Illuminis Insight Software, automatically analyses data from Sage, Microsoft Dynamics, Xero, Exchequer, Pegasus Opera, SAP Business One, Brightpearl and many other ERP systems to identify your fastest-growing customers and highlight new sales opportunities.
Instead of spending hours comparing spreadsheets, your sales and management teams receive live insights that help them focus on the customers with the greatest growth potential.
That’s why businesses across manufacturing, wholesale, distribution, engineering, construction, hospitality and professional services choose Illuminis Insight Software as their trusted reporting and data partner—helping them uncover opportunities hidden within the data they already own.
