# DenQAI: purchasing vendor workbook

File-specific companion · 2026-09-10

## Purpose

Which comparable offer has documented economics and acceptable sourcing and exit terms?

**Who:** Owner, purchasing lead, clinical reviewer, and relevant contract reviewer

**Records:** Same-scope written quotes; package sizes and usable units; freight/tax/fees; received rebates; sourcing, service, and exit records.

## Complete the file

1. Read Start Here and replace coded fictional Quote Inputs with one annual comparable scope.
2. Inspect Calculations while keeping documented invoice economics separate from uncertain operating scenarios.
3. Complete Sourcing Checks and GPO Review, then resolve questions before relying on Decision Summary.
4. Treat Hypothetical Charter as a design worksheet rather than an operating program.

## Definitions

- **Usable-unit rate:** Fraction of purchased units assumed usable in the modeled denominator.
- **Received annual rebate:** Rebate actually received for the comparable period.
- **Operating scenario:** Entered labor, waste, downtime, recurring, or exit effect kept apart from documented invoice economics.

## Fictional example

Fictional example: Offer A and B both quote 120 packages of 20 capsules; one has lower package price but higher shipping. Compare the documented result and operating assumptions separately.

## Review and next action

Request the missing quote or sourcing term that prevents a defensible comparison.

The guided workbook compares entered offers; it does not endorse vendors, certify products, verify quotes, or create purchasing authority. Excluded offers do not enter the comparison. Missing prices and undefined unit costs are unavailable, not free or zero-cost offers.

## AI coach prompt

Help me use DenQAI’s purchasing vendor workbook. My question is: Which comparable offer has documented economics and acceptable sourcing and exit terms? Explain these terms in plain language: Usable-unit rate, Received annual rebate, Operating scenario. Ask one question at a time about the required records: Same-scope written quotes; package sizes and usable units; freight/tax/fees; received rebates; sourcing, service, and exit records. Walk through the supplied fictional example before asking me for inputs. Treat every missing value as unknown, not zero. Do not invent source records, contract terms, legal conclusions, or clinical facts. Use only permitted fictional or aggregate, non-identifying information. Follow this boundary: The guided workbook compares entered offers; it does not endorse vendors, certify products, verify quotes, or create purchasing authority. Excluded offers do not enter the comparison. Missing prices and undefined unit costs are unavailable, not free or zero-cost offers. End with the missing evidence and this next step: Request the missing quote or sourcing term that prevents a defensible comparison.

Review my permitted fictional or aggregate draft of DenQAI’s purchasing vendor workbook against the file instructions. Check each required field and period, units, evidence locator, assumptions, arithmetic where formulas are actually supplied, and unresolved contradictions. Check the sequence: Read Start Here and replace coded fictional Quote Inputs with one annual comparable scope. Inspect Calculations while keeping documented invoice economics separate from uncertain operating scenarios. Complete Sourcing Checks and GPO Review, then resolve questions before relying on Decision Summary. Treat Hypothetical Charter as a design worksheet rather than an operating program. Separate facts from assumptions and missing records. Do not supply unsupported numbers or make a professional decision for me. Apply this limitation: The guided workbook compares entered offers; it does not endorse vendors, certify products, verify quotes, or create purchasing authority. Excluded offers do not enter the comparison. Missing prices and undefined unit costs are unavailable, not free or zero-cost offers. Return corrections, questions for the responsible reviewer, and the next action.
