What Is a Vendor Management System (VMS)? | Benefits, Features & How It Works

What is a Vendor Management System (VMS)?

A Vendor Management System (VMS) is a software platform that helps organizations manage their contingent workforce and staffing vendors more efficiently. A VMS provides the visibility, control, and automation needed to optimize spend, compliance, and performance across all non-employee labor - including contractors, temporary staff, and consultants.

 

 


A Vendor Management System (VMS) is a Centralized Hub

A VMS will centralize, automate and consolidate your entire contingent workforce processes in one easy-to-use software solution. This tech solution will allow you to manage vendor relationships and measure vendor performance, as well as procure, manage and pay non-employee workers sourced either through a staffing agency or another sourcing avenue. 

Essentially, a VMS acts as a centralized hub where businesses can:

  • Procure and onboard contingent workers,
  • Manage vendor performance,
  • Track time, invoices, and costs
  • Gain data-driven insights into their extended workforce

By replacing manual processes with automated workflows, vendor management systems save time, reduce costs, and increase visibility across the entire workforce lifecycle.

By acting as a system of record for your company’s contingent workforce, a vendor management system will capture and store the data you need to make better vendor and hiring decisions in one centralized location (as opposed to being fragmented across your entire organization.

How Does a Vendor Management System Work?

A VMS connects all the moving parts of your contingent workforce program in one platform. It serves as the system of record for all vendor and worker data - ensuring accuracy and efficiency. 

Typical VMS features include:

  • Requisition and approval workflows for job orders

  • Automated onboarding and compliance management

  • Time and expense tracking for non-employee workers

  • Invoicing and payment automation

  • Analytics and reporting for workforce visibility

Instead of relying on spreadsheets or email chains, companies using a VMS can manage hundreds of vendors, track performance in real time, and control costs with precision.

How a Vendor Management System Works

 

Why a Vendor Management System is Important

The contingent workforce has grown dramatically - up to 30% of the U.S. workforce today is non-permanent labor, and that number continues to rise.  Yet many organizations still rely on manual tools like Excel or SharePoint to manage this complex ecosystem. These outdated methods lead to:

  • Human errors and compliance risks

  • Inefficient processes and overspending

  • Fragmented visibility across business units

Implementing a VMS transforms contingent workforce management by automating processes, reducing risk, and giving HR, procurement, and finance teams unified visibility.

Key Benefits of a Vendor Management System

A modern VMS delivers measurable ROI. Here’s how:

1. Improved Efficiency

Automation of onboarding, time entry, and approvals saves countless hours while reducing administrative overhead.

2. Full Visibility

All data lives in one platform, enabling clear insight into worker performance, vendor spend, and compliance.

3. Vendor Consolidation

Centralizing vendors enables better performance tracking and smarter sourcing decisions.

4. Cost Savings

By eliminating rogue spend, improving rate management, and optimizing vendor usage, companies can save up to 20% on contingent workforce costs.

5. Risk Reduction

A VMS ensures workers are classified correctly, credentials are up-to-date, and contracts meet compliance standards.

Vendor Management System Pricing and ROI

Historically, VMS platforms were designed for large enterprises and came with complex pricing.
Today, cloud-based VMS solutions like Conexis VMS offer powerful functionality for mid-market organizations at a fraction of the cost.

When choosing a VMS solution, one of the biggest factors in your decision will be pricing.  Here's what you need to know about VMS solution pricing models: 

1- The Traditional VMS Pricing Model

Once implemented, VMS providers typically charge a percentage of every dollar that is processed through the Vendor Management System. Depending on spend levels the cost of a VMS could be as low as 35 basis points and go up as high as a full percentage point assessed on spend processed through the system.

2 - Monthly License Fee

Recently, some VMS providers have begun to offer a more traditional monthly license fee which is tied more to the data processing costs (which when you think about it aligns more with the VMS’ cost structure). These license fees start as low as a few hundred dollars and can go into the millions per year depending on the scale and complexity of the processing required.

Be Aware: The Hidden Costs of VMS Pricing

Processing and implementation aside - there are many hidden costs that you might not be aware of. When evaluating VMS providers, be sure to ask these about these potential hidden costs. You can also find a list of specific questions to ask in our free VMS Buyer's Guide.

Here's a rundown of some potential hidden costs. You can learn more about each of these at How Much Does a VMS Cost

1- Integration Complexity: VMS solutions must integrate with existing systems such as HRIS, ERP, and procurement software. If the integration is complex, it can lead to significant costs in time and resources. Be sure to ask the VMS if they have an open or closed API. An open API will be more cost-effective and give you control over the integration.

2 - Change Management: Employee resistance to new systems can be costly. Effective change management requires training and possibly even shifts in company culture, which can be resource intensive. Find out from the VMS how they handle and support your change curve.

3 - Customization: Solutions may not fit your company’s unique processes. Customizations can be expensive and time-consuming and may require ongoing maintenance. Find out from the VMS how they handle and charge for customization.

4 - Data Migration:  Transferring data from old systems to a new VMS can be a hidden cost, particularly if the data needs to be cleaned up or converted to a new format. Find out from the VMS if there are any costs for this. 

5 - Compliance and Security: Ensuring the VMS complies with labor laws, data privacy regulations, and industry-specific compliance standards can incur costs, particularly if you operate in multiple jurisdictions. Find out from the VMS what data privacy legislation they follow. GDPR is the gold standard.

6 - User Training: Staff will need training on the new system. This training can be costly, especially if the VMS is complex or if there is high turnover in the staff using it. Find out from the VMS if they charge for training, if its included or if they can train the trainer so you can conduct your own training.

7 - Ongoing Support and Maintenance: Monthly or annual subscriptions, support contracts, and updates for the VMS can add up over time. Find out from your VMS if they charge for updates or any other items as part of your subscription.

8 - Vendor Lock-in: If the VMS is not interoperable with other systems or data formats, it may lead to vendor lock-in, which can be costly if you decide to switch providers in the future. Your VMS should provide an open API ensuring easy migrations.

9 - Scalability: If your contingent workforce grows, the VMS must scale accordingly. Some VMS providers charge more as you scale up, which can be a hidden cost. Find out from your VMS what their back-end architecture is. The most advanced today is a micro server architecture which scales instantly providing a fast user experience regardless of the load being put on the system.

10 - Reporting and Analytics: Most VMS' have a set of standard reports and a way for you to generate your own reporting. However, some VMS' charge a cost to set up metrics and analytics to measure the performance of your contingent workforce through the VMS. Find out if there are any extra costs for the specific reporting and analytics that your business needs.

The Difference between a Legacy and a Modern VMS

For organizations managing a contingent workforce, the choice of Vendor Management System (VMS) can define how effectively they attract talent, control costs, and scale operations. Yet, too many businesses remain stuck with Legacy VMS providers; platforms built decades ago, patched over time, and unable to keep pace with today’s speed of work.

Modern VMS platforms, by contrast, are designed for flexibility, user experience, and rapid integration. The difference between a legacy provider and a modern solution isn’t just about technology, it’s about business outcomes.

If your organization is still operating on a legacy VMS, the consequences go beyond clunky software - they directly impact your bottom line, workforce agility, and competitive edge.

Here’s how:

  • Higher Costs: Legacy platforms often require ongoing customization, manual workarounds, and extra support fees that drive up your total cost of ownership.

  • Slower Time-to-Hire: Outdated workflows and long approval chains delay the hiring process, leaving critical roles unfilled.

  • Poor Visibility: Without real-time reporting, it’s harder to track spend, monitor supplier performance, or stay compliant with labor regulations.

  • Frustrated Stakeholders: Hiring managers, suppliers, and workers all struggle with complex systems that reduce engagement and adoption.

  • Missed Opportunities: While competitors leverage AI-driven insights and automation, legacy users risk falling behind in workforce strategy and cost control.

By contrast, a modern VMS empowers your business to:

  • Scale faster with flexible, mobile-first workflows

  • Control spend through automation and transparency

  • Engage suppliers and workers with user-friendly tools

  • Unlock strategic insights that drive smarter workforce planning

In other words: moving to a modern VMS isn’t just an IT upgrade - it’s a business decision that directly improves efficiency, cost savings, and agility
