What TenderOS is

TenderOS is a web-based platform for business and strategic procurement teams running tenders and requests for information, quotations, or proposals. It covers the process from creating a tender through supplier selection and award. Templates, supplier responses, and centralized questions and answers support RFI, RFQ, and RFP workflows. TenderOS normalizes bids so buyers can compare price, quality, delivery time, sustainability, and technical requirements. Its TOSY AI assistant can help draft tenders, review documents and offers, and suggest recommendations, while the buyer keeps decision responsibility. Suppliers respond through a portal without needing a license. The cloud service offers API access and custom integrations in its Enterprise package and is described as complementing existing ERP and category-management systems. TenderOS says data is hosted in Germany, processed in the EU, handled under GDPR, and not used to train AI models. Pricing is on request, with no free plan.
