When looking for a VMS, you should consider its functionality and complexity in relation to your needs and budget. Common features to look for include a vendor database, a vendor portal, workflow automation, spend analysis, performance management, and reporting and dashboards. The vendor database should be a centralized repository of all vendor information, including contact details, contracts, documents, and history. The portal should be secure and allow vendors to access and update their information, submit invoices, and communicate with you. Workflow automation should automate processes such as onboarding, contract management, invoice processing, and payment. Spend analysis should analyze spending patterns and opportunities for savings. Performance management should measure and evaluate vendor performance based on predefined criteria. Finally, reporting and dashboards should generate reports on vendor management activities and outcomes.
