description: Build a client onboarding plan for a newly signed engagement covering documents needed, access, first-30-days milestones, and the communication cadence. Use this skill whenever a firm has just won a client and needs to start them well, and says 'build a client onboarding plan', 'what do we need to onboard this client', 'kick off this engagement', or 'the handoff from sales to delivery is messy'. Trigger whenever a signed client needs a structured start to the engagement.

# Client Onboarding Plan Builder

## What this does and why it matters
The first two weeks set the tone for the entire engagement. A client who experiences a crisp, organized start trusts the firm with bigger work; one who experiences a slow, confused handoff starts looking for the exits before the real work begins. This skill builds an onboarding plan that gets the documents, access, and expectations sorted fast, so the team can start delivering instead of chasing logins. A strong onboarding is also where sales-to-delivery handoffs stop leaking context.

## Inputs to gather
1. The client, the engagement scope, and who owns it on the firm side.
2. What the firm needs from the client to start (documents, access, data, approvals).
3. Key contacts on both sides and their roles.
4. The first meaningful milestone and its target date.
5. The intended communication cadence and channels.

## Method
Work backward from the first milestone to identify everything that must be in place before the team can deliver it, and make gathering those items the first phase. Separate what the firm does from what the client must provide, and put a date on each client obligation so onboarding does not stall on a missing document. Establish the communication rhythm explicitly (who meets whom, how often, on what channel) so no one wonders whether they are being ignored. Capture the context that should carry over from the sales conversation, since the client should never have to repeat what they already explained. Keep the first 30 days concrete and light, with one early win that proves momentum.

## Output format
ALWAYS use:

# Onboarding Plan: [Client] | [Engagement]
## Kickoff summary (scope, owners, first milestone)
## Client responsibilities (item | owner | due date)
## Firm setup tasks (access, tools, internal briefing)
## Contacts and roles (both sides)
## Communication cadence (who, when, channel)
## First 30 days (week-by-week, ending in an early win)
## Context carried from sales (so nothing is repeated)

## Anti-patterns to avoid
- Starting delivery before access and documents are actually in hand.
- Losing the sales context so the client repeats themselves.
- A vague cadence that leaves the client wondering if work is happening.
- No early win, so the client waits weeks to feel value.

## Example
An onboarding plan for a new bookkeeping client lists the bank and accounting access needed with a Friday due date, assigns the internal team briefing, sets a weekly Thursday check-in, and targets a clean first month-end close as the 30-day early win, with the client's stated pain about late reports carried over from the sales call.
