Where Zephior goes further
What changes for your bid team.
Free search, then the bid
The public tender directory on zephior.com/tenders is free to browse without an account. When a tender fits, Ziva reads the full tender package and drafts the response.
Qualification on the documents
Before you commit a team, Ziva reads the tender documents against what your company can prove and shows where you are strong, where you are exposed and what only you can answer.
The submission files, finished
Ziva fills the buyer’s own Excel forms and price sheets, writes the proposal in their Word template and assembles the package as Word, Excel, PowerPoint and PDF files.
A bid team when you need one
Our Zelius bid team can take on a tender with you in the same workspace, scoped per bid.
