Vendor Management System: Key Facts

A vendor management system (VMS) helps businesses onboard, interact and transact with their external workforce, such as materials’ vendors (suppliers), wholesalers, service contractors, freelancers, and more. A custom vendor management system is a way for companies to improve the efficiency of their unique vendor-associated workflows and leverage a consistent and well-regulated approach to vendor selection, collaboration and assessment.

The implementation of a vendor management system pays off as:

  • Time savings due to vendor self-onboarding and elimination of in-person negotiations and email-based document exchange.
  • Cost savings due to transparent price bidding and low-risk vendor contracts.

Functionality Needed for Effective Vendor Management

Below, ScienceSoft have summarized functional capabilities that form the core of a vendor management solution.

Vendor self-registration workflow

You can define what information you need from your vendors to work with them productively ever after and include relevant steps/fill-in fields/document requirements in the registration process.

Vendor onboarding workflow

By setting a vendor assessment framework, you can have a VMS to automatically score registered vendors against needed criteria. Such a pre-onboarding step helps create a low-risk vendor portfolio.

Vendor profile management

In a VMS, vendors are offered to manage their business information independently. This helps maintain vendor profile information up-to-date and doesn’t require direct control from your team.

Vendor segmentation

You can plan and implement the best-suited segmentation model for your supplier base, for example you can give the highest strategic priority to suppliers of high-volume or high-value products.

A purchase requisition form

A document that describes required products/services. You can create as many requisition templates as needed for different department and procurement purposes.

Requisition approval

A VMS routes a requisition through the approval process and sends automated notifications to responsible employees according to the rules you have set in the system. Approval mechanisms can be multi-level and span different departments.

Request for quote (also called Invitation for bid)

Suppliers are notified when they are invited to participate in a bidding process. They can further submit their offering for price competition.

Processing bid responses

Upon the expiry of the bid submission period, you evaluate the bids and decide for a vendor of choice. No need for manual tracking of emails from vendors and no risk to miss a price quote.

Automated purchase order creation from a requisition

If you are not interested in price bidding, you can set to have purchase orders created automatically from approved requisitions and sent to a vendor of choice. Thus, you avoid one manual step and prevent procurement delays.


An invoice is created automatically from an approved purchase order or for a part of an order. Taxes are applied based on origin- and destination-based tax rules. The invoice is immediately available for you to pay.

Order management

Via a VMS, you gain full visibility into all your procurement orders. You can track order progress, contact vendors for explanation of delivery delays, and access shipment documents.

Business intelligence

An in-built tool to analyze vendor performance data and uncover opportunities for cost savings and risk mitigation.

3 Types of Vendor Management Systems

ScienceSoft suggests that a vendor management system may be helpful for the three different business processes.

VMS for staffing needs

Helps create a talent pool to manage contingent workers and service providers. When a job position is opened in a VMS, relevant candidates from a talent pool are immediately notified and can apply for it, which makes the hiring process really fast.

Check out helpful features

  • Full visibility into available external workforce: experience, certifications, work expectations, contacts.
  • Automated onboarding processes.
  • Digital document exchange allowing for space and time savings.


VMS for direct procurement (to manufacture products)

Helps create a supplier base for raw materials and ingredients, and make procurement requests online. Less reliance on in-person supplier communication and email messaging helps not be late with raw materials or ingredients supply and allows for uninterrupted manufacturing processes.

Check out helpful features

  • Faster requisition flow: online creation of purchase requisition, approval notifications, automated creation of purchase order from an approved requisition.
  • Volume-based price bidding.
  • Online billing and payment.


VMS for indirect procurement (for non-production-related needs)

Helps create a unified base of all suppliers of goods and services needed to maintain your organization’s life. In this case, the system targets to support internal processes and contributes to staff satisfaction, comfortable working conditions, timely facility maintenance, and more.

Check out helpful features

  • The list of suppliers for each provision need and supplier rating.
  • Scheduled reorders for recurrent supplies.
  • Role-based access and approval permissions.
  • Importing of spreadsheets with supply requests to a VMS.


Useful Integrations for Different Vendor Management Systems

As far as the processes assisted by a vendor management system are from different business areas (human resources, manufacturing, office administration), various business systems may be involved. We at ScienceSoft have thought of the most important system integrations for a VMS, yet your particular situation may require a different integration map.

Useful integrations for different vendor management systems - ScienceSoft

VMS + accounting software

  • To deliver invoices directly to the responsible team, thus eliminating protractions usually caused by manual transfers.
  • To pay contractors.


  • To rely on manufacturing capacity plans for raw material procurement, avoiding understocks and overstocks.
  • To provide visibility into procurement order statuses for the staff without access to a VMS (e.g., a procurement planning team).

VMS + HR management software

  • To provide information on current talent gaps and vacant positions needed for a limited period of time (e.g., for a project).

VMS + Intranet

  • To collect office supply requests from the staff and organize them into requisition lists.

Factors Affecting Vendor Management Efficiency

Relying on 19 years of experience in vendor portal development, ScienceSoft’s consultants have defined important factors that help bring the customer additional value across vendor management processes.

E-document management

to create, e-sign, and exchange documents with vendors digitally.

Vendor rating functionality

to automatically score vendors based on user-defined vendor performance assessment criteria.

Maximized workflow automation

to eliminate manual efforts across all kinds of vendor-associated approvals, vendor payments initiation and control, escalation of challenging situations and delays, and other rule-based vendor management tasks.

Well-designed onboarding and offboarding checklists

that cover documentation requirements, work instructions, access to corporate resources, and introduction to the team for various team roles, different company’s subsidiaries, remote and in-office positions to streamline administrative processes and set positive work experience.

The ROI for vendor management software implementation can be measured in:

  • Time savings. Your team will spend less time managing vendor relationships if the process is standardized and its part is given for vendors’ self-service.

  • Cost saving. Naturally, disorganized processes don’t leave a chance to see a big picture and make strategic decisions regarding vendor selection and contract negotiations. Operating in a vendor management system, you can assess vendors against your quality criteria from the start.
