Gather these records before you start
Use the current written quote, product labeling, FDA decision record, recall search, service schedule, warranty, software terms, training scope, consumable schedule, financing agreement, and any study the vendor uses to support a material claim. Save the publication or decision date with every source. A screenshot or sales slide can help locate a claim, but it should not replace the underlying record.
Run one worksheet for each competing configuration. Use the same collection, treatment-volume, staffing, downtime, financing, and resale assumptions across options. If a field cannot be verified, label it unknown. That keeps a company statement, a market observation, and your own forecast from being treated as the same kind of evidence.
Bring the completed worksheet to the vendor review and assign each open question to a named person. For any answer that changes price, support, permitted use, or exit cost, ask where that term appears in the final agreement. Recheck the configuration and attachments before signature because a revised quote can change the equipment bundle, warranty dates, software term, or financing schedule without changing the sales summary.
Keep the completed record with the signed contract for later reference.
