How and who for the hotel job—verified when attested. Advice unless labeled verified. This brief is a worksheet, not an appraisal and not a quote.

## The job

When a contract is up and the deck is all logos, I want a 90-day proof so I can renew, cut, or renegotiate on a number the owner will read.

**Outcome the catalog names:** A one-page ROI with a named baseline, a named window, and a caveat. Renew or exit written before the sales call.

**Desk:** owner
**Urgency on the catalog:** This renewal
**Typical budget band (catalog, not a quote):** $8–25k review
**Typical timeline (catalog, not a promise):** 2–4 weeks of evidence, not a new project

## Scoped brief

Pick one contract. Rebuild the promise as a number you can observe in 90 days. Pull the baseline from the PMS or the utility, not from the vendor QBR. Ashcroft sits on the owner side. A kill is a successful job.

1. **Restate the promise as a criterion.** If they sold ‘efficiency,’ write the labor hours or the kWh. If they sold ‘direct mix,’ write contribution after commission.
2. **Lock the baseline before the argument.** Same season, weather-normalized if energy, occupancy-held if mix. The vendor does not pick the baseline.
3. **Write the caveat on the same page.** What would have happened anyway. What you cannot attribute. Harbor will not list a proof without a caveat.
4. **Decide before the renewal call.** Renew, cut, or renegotiate. Shopping operators in the same breath is only leverage if you mean it.

## When not to buy

Do not hire the vendor to grade their own homework. A referral-fee advisor is not an advisor.

## Provider shortlist

## Success the brief names

- Baseline and window written before evidence pull.
- Caveat on the same page as the number.
- Renew/cut/renegotiate decided before the sales call.

## Pitfalls

- Letting the vendor pick the window.
- Counting logins as value.
- An advisor paid by the vendor under review.
