How to Find Your Most Profitable Customers in Sage 50

Every business knows who their biggest customers are.

Far fewer know who their most profitable customers are.

The two are rarely the same.

One customer may generate hundreds of thousands of pounds in sales while delivering very little profit. Another may spend far less but consistently produce excellent margins with very little support.

For many SMEs using Sage 50, identifying profitable customers isn’t straightforward.

The information exists within Sage 50, but turning that data into meaningful profitability reports often requires significant manual work in Excel.

Revenue Doesn’t Tell the Whole Story

Most standard sales reports focus on turnover.

But turnover alone doesn’t answer important management questions such as:

  • Which customers generate the highest gross profit?
  • Which customers have the best margins?
  • Which customers are becoming less profitable?
  • Which customers require the most discounts?
  • Which industries deliver the greatest return?
  • Which salespeople generate the most profitable business?
  • Which customers are no longer worth pursuing?

Without this information, businesses can easily focus their efforts on the wrong customers.

The Excel Challenge

We’ve seen many businesses export customer sales from Sage 50 every month before combining it with product costs, discounts, rebates and other financial information inside Excel.

The process often involves:

  • Multiple Sage exports
  • VLOOKUPs or XLOOKUPs
  • Pivot tables
  • Margin calculations
  • Manual adjustments
  • Charts for management meetings

Every reporting period, the same work is repeated.

One Finance Director from a distribution company told us:

“Finding our most profitable customers took longer than actually meeting them.”

Profitability Isn’t Static

Customer profitability changes constantly.

Raw material costs increase.

Discount structures change.

Buying patterns evolve.

Margins fluctuate.

If profitability reports are only produced once a month—or worse, once a quarter—management teams often miss opportunities to improve performance.

Having access to live profitability information allows businesses to make better pricing decisions, identify high-value customers and protect margins before problems become significant.

We Recreate the Reporting You’ve Already Built

At Illuminis Insight Software, we understand that every business measures profitability differently.

Some include carriage costs.

Some allocate overheads.

Some analyse by product group.

Others calculate profitability by branch, department or salesperson.

That’s why we don’t provide generic reports.

Instead, we review the reports your business already trusts.

We analyse your spreadsheets, understand your calculations and recreate your reporting logic inside Octelas.

Nothing is lost.

Everything becomes automated.

A Real Customer Story

A manufacturing company approached Illuminis Insight Software because their sales team focused almost entirely on turnover.

The Managing Director suspected some of their largest customers were actually producing very little profit, but proving it required several days of manual spreadsheet analysis every month.

Our consultants reviewed their existing Excel reports, understood how they calculated profitability and recreated the entire reporting process inside Octelas.

Today, management can instantly identify:

  • Their most profitable customers
  • Customers with declining margins
  • High-volume, low-profit accounts
  • Profitability by product group
  • Profitability by salesperson
  • Profitability trends over any date range

The Sales Director later commented:

“We completely changed our sales strategy. We stopped chasing turnover and started growing profit.”

The project paid for itself far quicker than the customer expected, simply because better information led to better commercial decisions.

It’s More Than a Dashboard

Many businesses investigating customer profitability also consider Microsoft Power BI.

Power BI can certainly display attractive charts.

But someone still has to define what “profitability” actually means for your business.

Someone needs to build the calculations.

Maintain the data model.

Update reports when your pricing changes.

Support users.

Make future enhancements.

That’s where many BI projects become expensive.

The technology isn’t usually the problem.

The ongoing maintenance is.

Your Data Partner, Not Just Your Software Provider

Illuminis Insight Software takes a different approach.

We don’t simply deliver a reporting solution and disappear.

We become part of your team.

We work alongside your finance department and management team, continually improving your reporting as your business evolves.

Need profitability by customer group?

We’ll build it.

Need to include rebate calculations?

We’ll add them.

Need to analyse profit by region or branch?

We’ll configure it.

Need to integrate another ERP or CRM system alongside Sage 50?

We’ll take care of it.

As your business changes, your reporting changes too—without you having to learn new software or hire BI developers.

Turn Better Insight Into Better Decisions

The businesses that grow most profitably aren’t always the ones with the biggest customers.

They’re the ones that understand where their profit really comes from.

Octelas by Illuminis Insight Software automatically extracts data from Sage 50, combines it with the information that matters to your business and delivers live customer profitability reporting without the need for manual spreadsheets.

Instead of spending hours building reports, your team can focus on improving margins, strengthening customer relationships and making more informed commercial decisions.

That’s why so many SMEs choose Illuminis Insight Software as their long-term reporting and data partner—because we don’t just help you understand your data, we help you use it to build a more profitable business.
