  • JAGGAER: Best for source-to-pay procurement

  • Gatekeeper: Best for vendor and contract lifecycle management

  • Proade: Best for specialized vendor-management requirements

  • VectorVMS: Best for contingent workforce management

What is a Vendor Management System?

Vendor management systems, also called contingent workforce management software, help organizations source, onboard, manage, and monitor external workers and suppliers. A VMS centralizes requisitions, candidates, contracts, compliance records, time, invoices, and supplier performance. Modern platforms can also support SOW and services procurement.

Key Features

  • External workforce management: Manage contractors, temporary workers, freelancers, and other non-employees.

  • Candidate and supplier management: Source talent, compare candidates, manage suppliers, and track performance.

  • SOW management: Define scopes, milestones, rates, deliverables, approvals, and budgets.

  • Workflow automation: Configure approval, onboarding, compliance, and offboarding processes.

  • Compliance management: Maintain documents, certifications, and required checks.

  • Time and expense: Track hours, expenses, approvals, and billing.

  • Analytics: Monitor spend, supplier performance, tenure, workforce metrics, and project progress.

  • Integrations: Connect with HRIS, ERP, procurement, finance, and enterprise systems.

Benefits

Procure Qualified Labor

A VMS gives procurement teams a structured way to create requisitions, source candidates, compare submissions, and manage approved suppliers.

Fill Positions Faster

Automated requisitions, notifications, candidate workflows, and approvals can reduce delays and reliance on spreadsheets and email.

Improve Compliance

A VMS can centralize documentation, automate checks, and create an audit trail for workforce processes.

Improve Workforce Visibility

Reporting helps organizations understand workforce volume, spend, supplier performance, and project progress.

Control SOW Spend

SOW features help teams define deliverables, milestones, rates, budgets, and approvals while tracking project performance.

Types of Contingent Workers

Organizations may use VMS software to manage:

  • Temporary workers: External workers engaged for a defined period.

  • Freelancers: Independent professionals hired for specific work.

  • Contractors: External workers supporting business or technical functions.

  • Consultants: Specialists brought in for expertise or projects.

  • SOW resources: External personnel working within a defined service engagement.

A VMS can manage different engagement types with the right workflows and approvals.

Healthcare VMS Software

Healthcare organizations often rely on contingent clinical and non-clinical workers, making compliance and credential management important. A healthcare-focused VMS can help track licenses, certifications, onboarding, assignments, and supplier performance.

Pricing Details

VMS pricing varies by workforce size, modules, implementation, integrations, and services. Enterprise platforms commonly use custom pricing. Buyers should compare software, implementation, integrations, and support costs.

Which VMS has the best workforce analytics and reporting?

SimplifyVMS is a strong option for workforce analytics and reporting, with capabilities for tracking workforce volume, spend, supplier performance, tenure, and other workforce metrics. VectorVMS also provides workforce reporting and spend visibility. The right choice depends on the reporting depth, data sources, and analytics requirements of the organization. 

Which is the best VMS for multi-country workforce? 

For organizations managing a workforce across multiple countries, a VMS should support configurable workflows, centralized reporting, compliance requirements, and regional processes. SimplifyVMS is a strong option for multi-country workforce programs because it supports configurable enterprise workflows and centralized management of contingent labor, suppliers, SOWs, and workforce data. Buyers should also evaluate localization and integration requirements for each region. 

Final Thoughts

Choosing the right VMS depends on how well the platform fits an organization’s workforce, supplier, SOW, compliance, reporting, and procurement needs. SimplifyVMS, JAGGAER, Gatekeeper, Proade, and VectorVMS each serve different requirements. 

Enterprises should compare workflow flexibility, SOW capabilities, workforce analytics, integrations, multi-country support, implementation, and pricing before making a decision. The best VMS is the one that aligns with the organization’s processes and provides the visibility and control needed to manage its external workforce effectively.
