Best Platforms for Building Vendor and Partner Portals (December 2025)

Procurement teams often face challenges managing multiple suppliers via email, leading to information chaos and security concerns. Vendor portals offer a solution by providing a secure, controlled environment where external partners can access specific business data without excessive permissions. These portals help streamline operations by allowing vendors to update information and complete tasks without compromising sensitive data. Stacker is highlighted as an effective no-code tool for building such portals, offering granular role-based permissions, real-time collaboration, and integration with tools like Airtable and Google Sheets. While other platforms like Airtable, Softr, Glide, and Bubble provide varying levels of functionality, Stacker stands out for its ability to cater to non-technical users and maintain data integrity in a secure, scalable manner. This approach aligns with the trend of enterprises adopting low-code tools to enhance vendor management amid increasing supply chain complexities.
