Working tools / Three transparent models
Decision tools for proposals, tenders and automation
Turn an early commercial question into a reviewable first estimate. Each tool exposes its assumptions, separates evidence from judgment and gives you a result you can challenge with the people who own the work.
Decision model / Ziva
RFP response effort estimator
Estimate team hours and daily capacity for an RFP response from question volume, answer reuse, drafting, review, coordination, production and contingency.Decision model / Zelius
Tender bid or no-bid evaluator
Run a transparent tender bid or no-bid assessment across package completeness, mandatory gates, scope, evidence, capacity, evaluation, commercials and submission readiness.Decision model / Zenith
Automation ROI calculator
Estimate released capacity, monthly benefit, payback and first-year value from process volume, coverage, time saved, exceptions and operating cost.Method / Evidence
A useful estimate makes the next conversation more precise
These tools are designed for orientation before a detailed plan. They do not know your customer, tender package, employment cost, contract, systems or operating exceptions. Use the result to identify the assumptions that matter, then replace defaults with observed data and accountable decisions.
No input is sent to Zephior or stored on a server. The calculation runs in the page. If you need a delivery plan, bid decision or investment case, preserve the assumptions you used and review them with the relevant commercial, legal, operational and technical owners.
