How to Find Your Most Valuable Customers

Most businesses know who their biggest customers are.

Far fewer know who their most valuable customers are.

There’s an important difference.

Your biggest customer isn’t always your most profitable.

The customer placing the largest orders may also demand the biggest discounts, require the most support, return the most products or pay the latest.

If you only measure turnover, you’re only seeing part of the picture.

What Makes a Customer Valuable?

Every business defines value differently.

For some, it’s gross profit.

For others, it’s repeat business.

Some businesses value customers who always pay on time.

Others value customers who buy across multiple product ranges or have consistently increased their spending over several years.

Your ERP system already contains most of this information.

Whether you use Sage 50, Sage 200, Microsoft Dynamics 365 Business Central, Exchequer, Pegasus Opera, Dynamics NAV, SAP Business One, Xero, Access Dimensions, Kerridge, Intact, Brightpearl, Oracle NetSuite or another ERP system, the challenge isn’t collecting the data.

It’s turning it into useful information.

Looking Beyond Sales Value

Imagine being able to instantly identify:

• Customers generating the highest gross profit.
• Customers with the highest lifetime value.
• Customers whose spending grows every year.
• Customers buying the widest range of products.
• Customers placing regular repeat orders.
• Customers with the highest average order value.
• Customers who always pay on time.
• Customers generating high revenue but low profit.
• Customers becoming increasingly valuable over time.

These are the customers you should be protecting and developing.

Yet many SMEs don’t have this information readily available.

Excel Can Tell You What Happened. It Rarely Tells You What Matters.

Many businesses already produce customer reports.

Usually in Excel.

Someone exports sales data from the ERP system.

Builds pivot tables.

Creates graphs.

Emails a report every month.

The report lists customers by sales value.

But that’s only one measure of success.

One Managing Director told us:

“We’d spent years rewarding our biggest customers without realising some of them were our least profitable.”

A Real Customer Story

A manufacturing business approached Illuminis Insight Software because they wanted to understand which customers deserved more attention from the sales team.

Their reports came from Sage 200, but everything was analysed in Excel.

They could see turnover.

They could see invoices.

But they couldn’t easily identify which customers delivered the greatest long-term value.

We worked with their management team to define what “valuable” meant for their business.

It wasn’t just revenue.

It included:

• Gross margin.
• Frequency of orders.
• Product range purchased.
• Payment history.
• Growth over time.
• Customer longevity.

We then built automated reporting in Octelas that scored and ranked customers using those measures.

The sales team immediately had a clear picture of which relationships deserved the greatest investment.

The Sales Director later told us:

“We stopped treating every customer the same and started focusing on the customers that made the biggest difference to the business.”

Better Information Changed Their Sales Strategy

Another customer believed their top ten customers generated most of their profit.

The reporting told a different story.

Several medium-sized customers consistently delivered better margins, paid on time and increased their spending every year.

Those customers had received very little attention because they weren’t appearing at the top of traditional sales reports.

After changing their account management strategy, those customers became some of the company’s fastest-growing accounts.

The Managing Director later commented:

“The opportunity wasn’t finding new customers. It was recognising the value of the customers we already had.”

Reporting That Reflects Your Business

Every business values customers differently.

Some focus on profitability.

Some focus on recurring revenue.

Others prioritise growth, retention or strategic accounts.

That’s why Illuminis Insight Software doesn’t provide generic customer analysis reports.

We begin by understanding your business.

We review the reports you already produce.

We understand how your team defines customer value.

Then we recreate and improve those reports inside Octelas.

The result is reporting that reflects your business—not someone else’s definition of success.

Stop Spending Time Building Reports

Many SMEs already have someone creating customer analysis reports.

They’re often highly skilled with Excel.

But every month they repeat the same process.

Export data.

Update spreadsheets.

Check formulas.

Refresh reports.

Email management.

The reporting gets done.

But at what cost?

Imagine if those reports updated automatically every morning.

Imagine if your team spent their time acting on the information instead of producing it.

That’s exactly what automation delivers.
