## Quick answer

Delegate vendor comparison by establishing eligibility requirements first, then a decision rule for eligible options. Ask the assistant to gather consistent information from current official sources and the proposals you supply. Separate confirmed terms from unanswered questions. Keep vendor selection and commercial commitments with the authorized decision maker.

A vendor comparison is useful only if it supports a real choice. A long feature list can obscure the most important fact: one vendor may fail a requirement that the team cannot compromise on. Start with those gates before scoring nice-to-have features.

## Set eligibility gates

Write the conditions a vendor must satisfy to remain in consideration. Depending on the purchase, these might include service region, delivery date, required compatibility, a budget ceiling, or the willingness to meet your contracting process.

Avoid assuming that marketing language proves a gate is satisfied. “Enterprise ready” does not answer a specific security requirement. “Fast delivery” does not establish your required date. Ask for the relevant documentation, proposal commitment, or direct clarification.

After eligibility, choose a limited set of comparison criteria. Include implementation effort, ongoing operating requirements, support arrangements, total known cost, and exit considerations when they affect the decision. Give each criterion a reason tied to your actual use.

## Worked example: selecting a service provider

An illustrative studio needs a provider to produce printed materials for an event. The required delivery date and print specifications are fixed. The studio prefers a lower cost, but it will pay more for a vendor whose proposal confirms the full scope and timing.

The assistant should normalize the proposals: quantity, dimensions, finish, proof process, delivery, and known extras. If one quote excludes delivery or assumes a different finish, that discrepancy must be visible. A lower headline price is not directly comparable until the scope aligns.

The recommendation can then follow a clear rule: choose the lowest total confirmed cost among vendors meeting the required specification and delivery date. If none qualifies, return the missing requirement and decision needed. Do not choose a nonqualifying option to complete the spreadsheet.

## A vendor comparison assignment

> Compare the approved shortlist against our required specification and delivery date. Use current official documentation and the proposals I supply. First identify eligibility gaps, then compare total known cost, implementation work, support, and exit terms. Link each material finding to its source and label unanswered questions. Recommend the lowest-cost eligible option unless another criterion materially changes suitability. Do not contact vendors, negotiate, sign, or commit funds without separate authorization.

If you want the assistant to prepare clarification emails, authorize the recipients and have it draft precise questions. “Does this quote include delivery to the event location by the stated date?” is better than asking for a generic proposal refresh.

## Inspect the commercial assumptions

Separate one-time charges from recurring charges and optional services from required ones. Identify the volume, duration, or usage assumptions behind a quote. If the available information does not establish total cost for your scenario, say that rather than extrapolating confidently.

Review contracting, security, and financial questions with the relevant qualified team members. The assistant can organize evidence and highlight differences, but a comparison brief does not replace professional review of consequential terms.

Also include the cost of change. A vendor that looks attractive may require setup, training, migration, or ongoing manual work. Ask for known evidence and unanswered questions about those burdens, without inventing effort estimates.

Finally, preserve the decision rationale. Record why the chosen vendor fits the requirements and which assumptions need checking before execution. This helps the team revisit the choice if a delivery date or term changes.

## Frequently asked questions

### Should I use weighted scores?

Use them only when the weights reflect actual priorities and eligibility gates come first. A precise-looking score can hide missing evidence or incomparable proposals.

### Can the assistant negotiate?

Only with explicit scope and authority, and only through supported actions. Start with draft questions and reviewable proposed terms before allowing external negotiation.

### What if the cheapest vendor fails one requirement?

Report the failure and exclude it under the agreed rule. If you want to relax the requirement, make that a separate decision rather than burying it in the ranking.
