Vendor Management System (VMS)

What is a Vendor Management System?

A Vendor Management System (VMS) is software that helps businesses manage the entire vendor lifecycle in one place. It simplifies vendor onboarding, compliance, contracts, performance tracking, invoicing and payments, while giving businesses better visibility over their suppliers and contingent workforce.  

With everything in one system, it's easier to stay on top of vendors, paperwork, and day-to-day processes.

What does a Vendor Management System do?

A Vendor Management System (VMS) brings all your vendor information into one place, making it easier to manage suppliers from start to finish.  

Depending on the VMS software you choose, it can help with:

• Vendor onboarding and document collection  

• Contract and renewal management  

• Vendor compliance management  

• Purchase orders and invoicing  

• Contingent workforce management  

• Vendor performance tracking and reporting  

• Approval workflows and audit trails

How a Vendor Management System works

Most Vendor Management Systems follow a straightforward process:

1. Add a vendor - Create a vendor profile with business details, contacts, and required documents.  

2. Complete vendor onboarding - Collect contracts, certifications, insurance, and compliance information.  

3. Assign work or services - Issue purchase orders, approve requests, or manage contingent workers.  

4. Track performance - Monitor delivery times, costs, service quality, and agreed KPIs.

5. Manage payments and renewals - Process invoices, keep contracts up to date, and receive reminders before important deadlines.

Why businesses use a VMS

Managing suppliers through emails and spreadsheets works for a while...until it doesn't. As businesses grow, keeping track of contracts, compliance, invoices, and vendor performance becomes far more time-consuming.  

A Vendor Management System keeps everything in one place, helping teams work faster and make fewer mistakes.

It's also becoming a bigger priority. Deloitte's Global Chief Procurement Officer Survey found that 64% of procurement leaders are investing in greater supply chain visibility, while 61% are improving supplier information sharing and collaboration to strengthen resilience.  

A VMS helps businesses:

• Save time on everyday admin  

• Keep vendor records organised  

• Stay on top of compliance requirements  

• Monitor supplier performance  

• Make better purchasing decisions with real-time data

Key features to look for in a Vendor Management System

Do not expect every Vendor Management Platform to offer the same features, so choose one that suits your business needs. Look for:

• Simple vendor onboarding  

• Contract and document management  

• Vendor compliance management  

• Vendor performance tracking and reporting  

• Invoice and payment management  

• Approval workflows  

• Dashboards and real-time reporting  

• Integrations with your HR, finance, or ERP (Enterprise Resource Planning) systems  

• Cloud-based access for remote teams and multiple locations

Which businesses benefit most from a VMS?

A Vendor Management System is a good fit for businesses that regularly work with external suppliers, contractors, or agency staff, including:

• Growing SMEs managing multiple vendors  

• Recruitment and staffing agencies  

• Construction and engineering firms  

• Manufacturing businesses  

• Healthcare organisations  

• Retail and logistics companies  

• Businesses with a large contingent workforce  

The more vendors you manage, the more useful a VMS becomes for keeping information organised and reducing manual admin.

Vendor Management System example

Business: Growing construction company

Challenge: The company works with over 50 subcontractors. Vendor documents, contracts, and invoices are scattered across emails and spreadsheets, making it difficult to track compliance and renewal dates.

Solution: The business introduces a Vendor Management System to centralise vendor onboarding, contracts, compliance documents, and approvals.

Result: Project managers can quickly check vendor status, receive reminders before documents expire, and monitor supplier performance, while spending far less time on manual admin.

Vendor Management System vs procurement software

A Vendor Management System looks after your vendors, while procurement software helps you buy from them.

Common misunderstandings about VMS

There are a few common myths about VMS:

• "It's only for large companies." Many SMEs use a VMS to save time and stay organised.  

• "It replaces procurement software." A VMS manages vendors, while procurement software manages purchasing.  

• "It's only for contractors." A VMS can be used to manage all types of suppliers and service providers.

FAQs

1. Is a VMS only for managing contractors?

No. A Vendor Management System can manage all types of suppliers, including contractors, service providers, and product vendors. Many businesses use it to oversee their entire vendor network.

2. Can small businesses use VMS?

Yes. Many VMS platforms are designed for SMEs as well as large organisations. If you work with several vendors, a VMS can reduce admin and keep everything organised.

3. What's the difference between VMS and supplier management software?

Supplier management software mainly focuses on maintaining supplier information and relationships. A Vendor Management System (VMS) goes further by managing vendor onboarding, compliance, contracts, performance and, in many cases, contingent workers from a single platform.
