From Fax Machines to E-Invoicing: How Modern Logistics Integrates the Supply Chain

Does Logistics Matter? It’s the opening question of every Does Logistics Matter? podcast episode. When Anna Fuller, Senior Sales Executive at Descartes, joined me in the studio, her answer was simple and relatable: we are all affected by logistics every day.

From her early days standing in front of a noisy fax machine, waiting for customer orders to print, Anna has witnessed a massive transformation in how goods move across the world. Yet, despite decades of technological advancement, many supply chains still struggle with a fundamental challenge: getting legacy IT systems, modern software, and human teams to talk to one another seamlessly.

In this episode, Anna breaks down what is holding companies back from full digitalisation, why human resistance to change is often the biggest hurdle, and how emerging requirements, like mandatory e-invoicing, are pushing the industry forward.

The Digitalisation Paradox: Why Are We Still Talking About It?

It can seem surprising that in an era of AI and smartphones, digitalisation remains a top agenda item for logistics companies. But as Anna points out, modernising supply chain technology is neither quick nor cheap.

Core enterprise resource planning (ERP) systems are expensive and risky to replace. A company cannot simply swap out its core backend infrastructure every few years when a shiny new version comes along. If logistics breaks down, goods stop moving, and revenue grinds to a halt. As a result, many businesses continue to rely on legacy systems in place for decades.

The Human Factor and the “Rube Goldberg Machine”

Beyond the financial and technical risks of upgrading IT, Anna emphasises that human behaviour is often the primary bottleneck in digital transformation:

  • Fear of Change: People instinctively seek safety in familiar routines. Many fear that automation will make their jobs redundant or that unfamiliar software is a mysterious “black box” they cannot control.
  • Organic Complexity: Over time, legacy systems tend to evolve into fragile, custom-built networks, much like a Rube Goldberg machine. Workarounds and custom scripts get stacked on top of old architecture to solve immediate problems.
  • Loss of Knowledge: When key employees leave, they often take crucial knowledge of how those custom systems were originally configured, leaving companies afraid that touching one piece will cause the whole operation to collapse.

To overcome these obstacles, companies must invest in their people before investing in new systems. Involving operational staff early, mapping actual processes, and defining clear business goals ensures that tech implementations deliver genuine value rather than added complexity.

Unburdening Complexity: Making System Integration Invisible

Supply chains do not exist in a vacuum. A single business must coordinate with suppliers, logistics providers, and customers, each operating with different priorities, regulatory environments, and software capabilities.

When bridging the gap between cutting-edge, API-first solutions and decades-old legacy ERPs, flexibility is crucial. For most companies, managing complex IT integrations and Electronic Data Interchange (EDI) standards is not their core business. They simply want operational data to flow effortlessly in the background, like turning on a tap and expecting water to come out.

When done right, modernising order processing and EDI connections delivers game-changing results:

  • Faster Partner Onboarding: Streamlined integration frameworks cut onboarding time from indefinite delays to predictable, rapid setups.
  • Error Reduction: Automated data exchange minimises manual keying errors, ensuring critical shipments (such as fresh food deliveries) arrive on time without administrative delays.
  • Focus on Value: Teams can stop manually processing routine orders and focus on managing exceptions and building stronger customer relationships.

The E-Invoicing Imperative: A Mandate for Change

While EDI adoption has historically been driven by customer demands, a new wave of mandatory e-invoicing and e-reporting legislation across Europe and beyond is forcing companies to act.

For many finance departments, receiving structured digital invoices, machine-readable XML data rather than traditional PDFs or paper documents, can feel daunting. However, once companies navigate the transition, the benefits become undeniable:

“They can see that it does have advantages and that they are actually able to process a lot of invoices much faster. As a result, resources can be allocated to more value-added tasks.” – Anna Fuller

Step Back and Map the Process

Anna’s key advice for companies navigating digital transformation is to step back and closely evaluate their current workflows. By identifying where high volumes of manual, repetitive tasks occur, businesses can target automated EDI and e-invoicing solutions where they will save the most time, reduce operational risk, and deliver maximum business value.
