What TenderOS is
TenderOS is a web platform for reviewing tender documents, tracking compliance, and preparing bid responses. Its free Tender Analyzer works in the browser without sending documents elsewhere and requires no credit card. The preview returns requirement and mandatory-item counts, three example requirements, and counts of documents, dates, and flagged clauses. It does not include the full requirement list, compliance matrix, Company Brain, evidence matching, drafting, exports, or team access. Paid workspaces can store approved company materials such as profiles, certifications, insurance, case studies, CVs, policies, and answers. Drafts use tender requirements and approved evidence, flagging missing information rather than inventing company details. The platform includes approval workflows; Business separates editing from sign-off so users cannot approve their own evidence. Compliance matrices export to Excel, and response documents to Word or PDF. Starter is $299 a month and includes one user, five tender workspaces per month, and specified processing, draft, and storage limits. Business is $799 a month, and Pro is $1,499 a month. Enterprise pricing is by annual contract.

TenderOS is aimed at bid teams, pre-sales and sales engineering teams, government contractors, and IT, SaaS, construction, and engineering vendors. Its free analyzer may suit someone seeking a limited browser-based preview before considering a paid workspace.
