The best open source VMS should monitor products and services provided by various vendors. They must be safe and comply with the laws and regulations.

Additionally, the software should have a vendor portal and allow the organization’s workers to carry out various roles on the platform.

It should store all vendor documents and other necessary information for easy access.

What is open-source vendor management software?

An open-source vendor management software is an application developed in collaboration with the public and made freely available for individuals or businesses. The open-source VMS makes managing and procuring staffing services easier to save time and minimize errors.

Open source means anyone can use, study, change, or even distribute it after modification. The source code is publicly accessible, unlike other software.

Open source VMS makes it easier for companies to tailor the source code to run vendor management operations. The copyright holder grants the users the right to alter the source code in open-source software. 

What should an open-source vendor management software do?

The vendor management process is lengthy and costly to be carried out manually. But a VMS can be customized to carry out the process to the end automatically.

Below is an overview of how this process automation reduces the department’s workload.

First, it identifies the organization’s needs and requirements. The software monitors various supplier performances. Then, it generates reports for the critical decision to keep renewing or ending the contracts. Finding the perfect solution becomes more straightforward once the organization’s needs and requirements are determined.

Secondly, it identifies potential vendors. The software initiates bids from vendors by allowing them to key in their details for the contract. Afterward, the software identifies each vendor’s strengths and weaknesses and analyzes risks posed.

Third, it initiates the contracts after selecting vendors by compiling the score reports in budget and business criteria. After signing the contract, the software helps the vendors to understand the delivery timelines and the reporting flow. It also enlightens the vendors on contract terms and all necessary obligations.

Fourth, it executes the contract by monitoring if deliverables are completed within the stated time frames. It also records the documents and the communication between the vendor and the necessary departments. And finally, it clears the financial terms.

Fifth, it monitors and generates reports on the vendor’s performance. Then it creates a report on improvement areas and the quality of the end products.

Lastly, it generates a report with a key decision to end or renew the contracts. If the contract ends, the cycle begins again.

1. Cost control

2. Tracking performance

3. Reporting and analytics

4. Expense management

The system should identify the vendors that pose higher risks and allocate substantial resources efficiently.

5. Data storage

The software should store all necessary documents and information in one data storage area for easy assessment.

6. Security and control

Recording all the activities makes it easier to trace any risk factor and address it accordingly. So, all operations should be carried out through the software.

7. Staff management

Every department is assigned a different role. The software manages the staff by providing a platform for each to carry out their duty.

8. Vendor portal
