the 90-day onboarding doc we wish someone had given us.
what to ship in days 0–30, 30–60, 60–90. the onboarding milestones that actually matter on a new retainer, the meetings to skip, and the receipt every client should have by day 90.
the first 90 days decide whether the retainer renews at month nine.
the first 90 days of a retainer determine the next 270. the milestones that matter are the ones that produce shared receipts — not the ones that produce shared decks. here is the doc, day by day, that we wish we'd had when we started.
most agency onboardings fail in week six. not week one. week one is fine — everyone is excited, the kickoff deck is sparkly, the first post lands. week six is when the relationship either has receipts to point at or doesn't. if it doesn't, the renewal call in month nine is a coin toss.
we wrote this doc after the fifth onboarding that went sideways for the same reason. it has held up across about forty retainers since. days 0–30 build the listening posts. 30–60 ships the first body of work. 60–90 produces the receipt.
— phase onedays 0–30 / the listening.
- 01the audit. 100 of the brand's last posts. 100 of the top three competitors. one page each. patterns named.
- 02the dm trawl. the cm reads the last 60 days of dms and comments. produces a list of the ten most-asked questions. these become the first month's content spine.
- 03the stakeholder call. 45 minutes. one question: what would make this retainer feel like a win at month nine? answer in writing. revisited monthly.
- 04the first post. ships in week three at the latest. small. specific. not the kickoff post. a real one.
the trap in this phase is decks. everyone wants decks. clients ask for strategy decks. account leads produce strategy decks. the deck gets reviewed for two weeks while nothing else ships. we now hard-cap month one decks at four slides. one for what we heard. one for what we'd ship. one for what we'd cut. one for what we need from the client. that's it.
the first 30 days produce two artifacts, not ten. anything more is the agency reassuring itself, not the client.
— phase twodays 30–60 / the body of work.
- 01the first 20 posts. in market. on schedule. all four formats — opinion, demonstration, receipt, community-response.
- 02the weekly community digest. the friday synthesis lands in the client's inbox every friday. it does not get rolled into the monthly report. it goes weekly.
- 03the hook bench. first proper shoot day. 30–40 hooks tested. survivors scripted in the second half of the month.
- 04the brand-voice doc. first draft. three pages. updated from the actual posts that shipped in weeks one and two.
this phase is where the agency learns whether the kickoff promises were realistic. almost half the time they weren't. we now build a small reset call into the end of week six: 30 minutes, one question, "what's harder than we thought." we own the answer. the client respects it more than they respect the optimistic version.
— phase threedays 60–90 / the receipt.
- 01the first compounding post. a post that performs at least 3x the median of the previous 60 days. if there isn't one organically, we plan one.
- 02the receipts doc. 8–10 pages. what we heard. what we shipped. what worked. what didn't. what we'll do next quarter. delivered before day 90, not on day 100.
- 03the audience map. the artifact paid and organic now share. first version goes out at day 75.
- 04the renewal conversation. we open it at day 80. not month nine. early enough that the answer is "yes, with these tweaks."
— section fourthe meetings we cut.
we cut the weekly status meeting after day 30. it gets replaced with a written update on monday morning — the planner walkthrough, in writing, in the same airtable the team works in. the meeting was theater. the written update is faster, more durable, and forces specificity. clients pushed back at first. nobody has asked to bring the meeting back.
we also cut the month-end "review deck." it gets replaced with the receipts doc on a quarterly cadence and the friday synthesis on a weekly one. the monthly review was a deliverable in search of a use. the receipts doc has a use. the friday synthesis is read on the day it lands.
— closingthe only question that matters at day 90.
"can the client point at three specific things and say 'this would not have happened without the agency'." if yes, you have a retainer. if no, you have a vendor relationship that will be re-pitched in six months, no matter how friendly the call is.
the doc above is the version we use to make sure the answer is yes more often than not. it has held up, with small tweaks, across about forty onboardings. the first 30 days are about listening. the next 30 are about shipping. the last 30 are about handing the client something they can forward to their boss. if you do those three things, month nine is a formality.
