Vendor Portal Development

Vendor portal development based on ready specifications
Our web developers build supplier portal software rigidly following the provided specifications about intended functionality.
Legacy vendor portal modernization
We enhance the performance of your existing solution, ensure its smooth integration with elements and safe data migration.
After the portal is launched, our team will continue maintaining and supporting the B2B portal software to ensure its high relevance in the future.
Troublesome ERP integration
The integration of the portal with ERP system is often long, complicated and painful process. But if you want to get truly automated business processes, reduce a great volume of routine manual actions and track relevant info on the business needs, a deep ERP integration is essential for your B2B Vendor portal, thus we ensure seamless integration with this internal system for you to get the most of the new solution.
Big and slow solution
As vendors differ in size, offering and collaboration model, to avoid unnecessary complexity, we keep what suits exactly for your business. Moreover, we can introduce various vendor account options, e.g. you can provide limited functionality for your minor vendors or integrate with the internal systems of your key suppliers.
Buyer-vendor communication failure
As any communication gap may cause massive loses (imagine a delivery delay notification being lost), we ensure that you’re kept up-to-date and nothing is left unnoticed with automated alerts, notification and live charts.
