FAQ – Supplier Portal Software
What is supplier portal software?
Supplier portal software digitizes collaboration between purchasing, planning teams and suppliers. It helps manage open purchase orders, delivery dates, quantity changes and supplier responses in a structured way. numi goes further by prioritizing critical purchase orders using ERP data, inventory, demand and operational risk.
How does numi reduce missing parts?
numi detects critical purchase orders early, links them with production orders, inventory and demand, and prioritizes them by business impact. This helps purchasing and planning teams focus on the supplier actions that matter before shortages disrupt production.
Can numi process SAP exception messages?
Yes. For SAP systems, numi can consume exception messages, structure them and prioritize them. Instead of unfiltered messages, teams receive operational alerts with clear relevance and recommended next steps.
How does supplier collaboration work without EDI?
Suppliers can be connected through automated emails with Excel responses, through the supplier portal or through API-based processes. This means not every supplier needs to be part of a rigid EDI project from day one.
What can suppliers do in the portal?
Suppliers can log in, review open purchase orders, confirm delivery dates, adjust quantities or reject changes. Responses are captured in a structured way and made usable for purchasing, planning and ERP workflows.
How are PO changes synced back to the ERP?
Confirmed date and quantity changes can be transferred back to the ERP automatically or through a controlled workflow. numi documents the change history, supplier response and ERP sync status.
Who uses the supplier portal software?
numi is typically used by operational purchasing, dispatching, production planning and supply chain teams. It is especially relevant for manufacturing, industrial companies and organizations with many open purchase orders, critical delivery dates or complex supplier structures.
Which KPIs can be improved?
Typical improvements include fewer missing parts, higher delivery reliability, less manual coordination effort, faster response times, lower inventory value and better traceability of PO changes. Actual results depend on ERP data quality, process maturity and supplier structure.
Is numi only a supplier portal?
No. The supplier portal is only one part of the process. numi detects risks, prioritizes critical purchase orders, supports escalations between planning and purchasing, coordinates suppliers via portal or email, and syncs confirmed changes back to the ERP.
