Curated AI Stack · Agencies and solopreneurs onboarding 2–6 clients per month

AI-Powered Client Onboarding Stack for Service Businesses (2026)

Onboarding fails when the client gets a generic welcome email and a Google Drive link that 404s. This stack automates welcome sequence, intake form → project hub, and kickoff brief generation — without hiring an ops person. Core: Notion (hub), Make (automation), Claude (brief synthesis). Typical cost: $29–47/month. Human kickoff call still required; AI handles prep and chase-up.

Stack Operator Reliability Score

Composite from core tools only — supplementary picks do not dilute the score. Your stack fails on the weakest glue, not the average.

Stack score = 0.60 × mean(core tool scores) + 0.40 × min(core tool score). Supplementary tools are listed but do not dilute the composite — your stack fails on the weakest core glue.

30-Day Implementation Plan

  1. Week 1 — Onboarding SOP on paper

    1. List every step from signed contract to “day 7 delivered.” No tools yet.
    2. Identify client actions vs your actions — who blocks progress?
    3. Build Notion template once manually for next client before automating.

  2. Week 2 — Notion hub live

    1. Clone template on next won deal. Send portal link in welcome email.
    2. Claude: intake form → internal kickoff brief. You edit before call.
    3. Log client time-to-first-action (upload assets, book kickoff).

  3. Week 3 — Make automation

    1. Deal won trigger → Notion duplicate → task assign → day 3 chase email if incomplete.
    2. Test with sandbox client name. Watch execution log for field mapping errors.
    3. Internal Slack notification with link to Notion — no “where is the file?” pings.

  4. Week 4 — Measure drop-off

    1. Which onboarding step loses clients? Fix SOP before adding tool #6.
    2. If automation saves 3+ hours per onboard, keep Make Core.
    3. Run useToolCraft wizard if service type diverges (e.g., productized vs custom).

How we curated this stack

This stack pairs 3 core and 2 supplementary tools around one weekly workflow. Tools in curated stacks are evidence-checked on a weekly schedule: pricing is read from the vendor page and compared with the catalog band, public user reports from the last 90 days are collected with sources, and a person reviews the result before it is published. The check date and sources sit under each tool above; job-in-stack copy is editorial, not a hands-on test claim.
