# Message parity checklist

- Hub: Website Design & Development

Compare your sales deck and your website against one message sheet. Label every pair and fix conflicts first.

Fill the message sheet first. Then compare the deck and the site to the sheet, not to each other. Whoever edits the deck last should not be the source of truth.
Fix conflicts today, orphans this week, gaps this month. Drift can wait for the next copy pass.

*Both follow the sheet. Neither is the source.*

## 1. Message sheet (one page)

Write what the company says. Eight lines. One owner, named at the top.

| Line | Our wording |
| --- | --- |
| Who it is for |  |
| Problem / trigger |  |
| Promise (one sentence) |  |
| Proof (cleared to show) |  |
| Next step (single) |  |
| Price posture |  |
| Timeline posture |  |
| Not for |  |

- [ ] Sheet owner (one name) and date
- [ ] Every line is something we say on a live call today. No aspirations

## 2. What gets checked

- [ ] Current sales deck (version and date)
- [ ] Homepage, main service pages, and contact page
- [ ] Other things buyers see: proposal template, capabilities PDF, first-reply email, email signature

## 3. Slide-to-section map

| Deck slide (title) | Site section (URL) | Label | Action and date |
| --- | --- | --- | --- |
|  |  |  |  |
|  |  |  |  |
|  |  |  |  |
|  |  |  |  |
|  |  |  |  |
|  |  |  |  |

- [ ] Labels used: match, drift, gap, orphan, conflict
  Match: leave. Drift: pick one phrase. Gap: add to the site or keep as a call point. Orphan: add proof or remove. Conflict: fix against the sheet.

## 4. The three places that break first

- [ ] Package names and price framing are identical on deck and site
- [ ] Every proof item on the deck exists in the proof source, and the site uses the same version
- [ ] The "who it is for" line is as narrow on the site as in the deck

## 5. Fix order

- [ ] Conflicts resolved against the sheet (today)
- [ ] Orphans: proof added to the deck, or the site line removed (this week)
- [ ] Gaps: added to the site or noted as a call-only point (this month)
- [ ] Drift: one phrase chosen, both updated (next copy pass)

## 6. Keeping it in line

- [ ] Change rule: the sheet changes first, then the deck and the site within one week
- [ ] Intake form asks "What did you read or see before contacting us?"
- [ ] Next audit date in the calendar (before launch, after any offer change, or quarterly)
