Managing vendors and suppliers with Excel and email often feels like the easy path – until it inevitably becomes a complex maze. What begins as a seemingly simple solution quickly transforms into a fragmented landscape of disparate spreadsheets, endless email chains, and scattered data. This environment is ripe for errors, missed deadlines, and ultimately, it becomes a significant obstacle to achieving procurement efficiency and strategic impact.

Effective vendor management is not merely an administrative task; it is essential for controlling costs, ensuring reliability, and crucially, reducing risks across your supply chain. However, relying on outdated tools like Excel and email fundamentally limits your organization's ability to scale, adapt, and truly thrive in a dynamic market.

In this article, drawing insights from an interview with Spencer Penn, Founder and CEO of LightSource AI, we will explore why the time has come to move beyond the limitations of Excel and email. We will also illuminate how AI-enabled platforms are transforming vendor and supplier management, making it a seamless, automated, and strategically capable function ready to meet the complex challenges of modern procurement.

What is Vendor Management and Why is It Important?

Vendor management refers to the critical process of strategically managing supplier relationships to ensure they consistently deliver the expected quality, reliability, and value. This involves a range of activities including evaluating performance, maintaining clear and consistent communication, skillfully negotiating contracts, and diligently tracking compliance to effectively mitigate risk.

Effective vendor and supplier management yields benefits far beyond simple cost savings; it significantly strengthens supply chain resilience and enhances your organization's agility and ability to respond effectively to market shifts and disruptions.

The primary goals of strategic supplier management are clear and impactful: ensuring on-time delivery, optimizing costs to drive value, and managing risk effectively across the supply base. Vendor and supplier management tools empower procurement teams by simplifying complex processes, maintaining vital consistency, and substantially reducing manual workloads. While Excel and email have served their purpose historically, they are increasingly inadequate in today's fast-paced and complex procurement landscape.

Why Excel and Email Are Still Prevalent (and Why That’s a Problem)

Excel and email remain widely used in vendor and supplier management largely due to their accessibility and familiarity. Most organizations already have these tools readily available, eliminating the need for an immediate learning curve or additional investment upfront.

Another perceived advantage is customizability. Excel offers procurement professionals the ability to create tailored templates, pivot tables, and specific calculations to fit their immediate needs for tracking performance metrics, compliance requirements, or costs. Email, on the other hand, is the default communication tool for most businesses – seemingly simple and effective for sending updates, managing requests, and maintaining contact records.

This combination of perceived flexibility with Excel and the universal reach of email makes them common choices for vendor management, particularly when dealing with a small and manageable number of vendors or suppliers. However, as supply networks inevitably expand and procurement becomes more strategic, these tools fall critically short in many essential areas.

The Significant Limitations of Using Excel and Email for Vendor or Supplier Management

While Excel and email may offer initial convenience, they come with significant and often detrimental limitations that hinder effective vendor management, particularly as the vendor base grows and procurement's strategic importance increases.

Data Silos and Fragmentation

A major drawback of relying on Excel and email is the creation of isolated data silos, where critical information is trapped within individual spreadsheets and personal inboxes. Collaboration becomes inherently challenging and inefficient when vital data is scattered across disparate files and communication threads, leading to confusion, missed opportunities, and a lack of a unified source of truth. As Spencer Penn aptly described, “Excel is better for the individual, but for an organization, it's like death. If I have an Excel spreadsheet, I’m aware of it and literally nobody else. Even if I save it to a common drive, it’s my own work, and there’s no way to do data capture.” This fragmentation makes it exceedingly difficult to consolidate information and gain a holistic, real-time view of overall vendor and supplier performance.

Scalability Challenges

As vendor networks expand and procurement operations become more complex, attempting to manage these critical relationships solely through Excel and email becomes an increasingly time-consuming and cumbersome process. Manually tracking dozens or even hundreds of contracts, compliance requirements, performance metrics, and communication records leads to significant inefficiencies and a heightened potential for human error. Spencer highlighted the inherent challenges of this manual process during his time at Tesla, stating, “We were just taking the drawings and emailing them to suppliers, then getting quotes back in Excel files. It was 500 emails to get a part with a supplier at a given price. It was hard to know if that price was fully fair or if there was margin padded in.” This manual burden prevents procurement teams from scaling effectively.

Lack of Automation

Excel and email fundamentally rely on manual processes for managing vendor information and workflows. Procurement teams are burdened with manually updating supplier records, tracking crucial compliance deadlines, and initiating contract renewal processes by hand. This critical lack of automation results in wasted time that could be dedicated to more strategic activities and significantly increases the risk of costly mistakes. Important tasks can easily fall through the cracks, leading to missed deadlines, compliance issues, and ultimately, negative impacts on the business. As Spencer pointedly noted, “Technically, you could cut your steak with a plastic fork—but it’s not going to help you very much.”

Version Control Issues

Version control is another common and frustrating problem when managing documents and data across multiple Excel files and email threads. Multiple versions of critical documents are often circulated simultaneously, leading to confusion and uncertainty over which one represents the most current and accurate information. Without a single, centralized source of truth, teams risk making important decisions based on outdated or incorrect data, potentially leading to significant downstream issues.

Limited Reporting and Analytics Capability

While Excel offers basic analytical capabilities, it fundamentally lacks the sophistication and power needed for modern, data-driven vendor management. Advanced data analysis, accurate trend forecasting, proactive risk assessment, and the ability to generate insightful reports are difficult or simply impossible to achieve with Excel alone. Spencer shared that, “At Tesla, there wasn't a good procurement system of record. We had an engineering system of record, a finance system of record, but procurement was done in Excel and email—leaving a massive tech gap.” This significant limitation means procurement teams miss out on the crucial opportunity to make proactive, data-driven decisions that could substantially improve vendor outcomes, optimize spend, and mitigate risks.
