How to Analyse Sales Trends Over Time

Most businesses know what they sold last month.

Far fewer understand why sales are changing.

Are sales genuinely growing?

Or is one large customer masking a decline elsewhere?

Is a product becoming more popular?

Or are sales simply seasonal?

Are margins improving?

Or are discounts increasing?

Without trend analysis, you’re making decisions based on snapshots instead of the bigger picture.

Every Business Has Trends Hidden in Its ERP Data

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, years of valuable sales history are already available.

The challenge is turning that history into meaningful information.

Imagine being able to compare:

  • Sales this week against last week.
  • This month against the same month last year.
  • Quarter-on-quarter performance.
  • Year-to-date sales.
  • Rolling 12-month sales.
  • Sales by customer over any date range.
  • Sales by product or product group.
  • Branch performance over time.
  • Salesperson performance over time.
  • Gross profit trends.
  • Average order value trends.
  • Customer buying patterns.

Those are the questions business owners ask every day.

Most Trend Analysis Happens in Excel

We’ve worked with businesses where sales trend reporting relied entirely on one Excel workbook.

Every week someone would:

  • Export sales from the ERP.
  • Copy data into Excel.
  • Refresh pivot tables.
  • Update graphs.
  • Change date ranges.
  • Check formulas.
  • Produce management reports.

It was a well-established process.

It was also taking a day or two every week.

One Commercial Director told us:

“We knew the reports were valuable because everyone wanted them. We just didn’t realise how much they were costing us to produce.”

A Real Customer Story

A national wholesaler contacted Illuminis Insight Software because they wanted to understand why certain product ranges were declining.

Their finance team produced monthly sales reports from Sage 200, but comparing trends over different time periods meant exporting data into Excel and manually rebuilding reports every month.

We spent time understanding the questions management regularly asked.

Not just total sales.

But trends by:

  • Customer.
  • Product.
  • Product group.
  • Branch.
  • Salesperson.
  • Region.
  • Time period.

We then built automated trend analysis dashboards in Octelas.

Managers could compare any period against another with just a few clicks.

Weeks.

Months.

Quarters.

Years.

Rolling periods.

Financial years.

Custom date ranges.

Instead of asking someone to build another report, managers could answer their own questions instantly.

The Commercial Director later told us:

“We’ve stopped asking for reports and started exploring the data ourselves.”

Finding Problems Earlier

Another customer believed one of their product ranges had suddenly declined.

The trend analysis showed something different.

Sales had actually been falling slowly for nearly eighteen months.

Because the change happened gradually, nobody had noticed.

By identifying the trend early, they reviewed pricing, supplier costs and marketing activity before the problem became significantly worse.

The Managing Director later commented:

“The trend was obvious once we could actually see it.”

That’s the difference between reporting what happened and understanding why it happened.

Every Business Asks Different Questions

Some businesses compare products.

Others compare customers.

Some analyse regions.

Others focus on account managers, branches or product groups.

Many need to compare completely different date ranges depending on the question they’re trying to answer.

That’s why Illuminis Insight Software never delivers generic reporting templates.

We start by understanding your business.

We review the Excel reports you’re already producing.

We learn which comparisons matter most.

Then we recreate and improve your reporting inside Octelas.

The result is reporting that’s designed around the way your business makes decisions.

Stop Rebuilding the Same Reports

One thing we see again and again is businesses asking someone in finance to produce the same reports every week.

“Can you compare this month with last month?”

“What did this customer buy this time last year?”

“Can you compare Product A with Product B over the last three years?”

Every one of those questions usually means another Excel report.

Another export.

Another manual task.

Those hours add up.

More importantly, they delay decisions.

Automation allows managers to answer those questions themselves, while giving your finance team time back to focus on work that really adds value.

At Illuminis Insight Software, we don’t simply deliver reporting software.

And as your reporting requirements grow, we continue developing new dashboards, reports and analysis.
