Replace $6K/Month of Back-Office Work With Claude Max and 11 MCPs

The premise

A typical small business back office — lead generation, sales support, content, marketing, accounting, operations, client communications, and hiring — runs $6,000 to $12,000 per month in combined headcount and SaaS.

A single Claude Max subscription at $200/month, configured with the right MCPs and skills, handles all eight functions. Not at the same level as dedicated humans, but good enough for most small businesses — and it runs 24/7 without onboarding.

Step 1: Get Claude Max

Claude Max ($200/month) is required for the Claude Code access and run limits needed to power a back office. Lower-tier plans hit rate limits too quickly.

Step 2: Install Claude Code

bashCopy
# macOS / Linux
curl -fsSL https://claude.ai/install.sh | bash

# macOS Homebrew
brew install --cask claude-code

# Windows PowerShell
irm https://claude.ai/install.ps1 | iex

Step 3: Install the 11 MCP servers

Install one at a time, verify each before moving to the next.

1. Context7 (docs lookup):
   promptCopy

   npx ctx7 setup --claude

2. Google Workspace:
   promptCopy

   uvx workspace-mcp --tool-tier core

   (requires Google Cloud OAuth app)

11. Plaid: optional, pairs with QuickBooks for live bank transaction feeds

Step 4: Install the skills foundation pack

• Anthropic official — pdf, docx, xlsx, pptx, writing-plans, executing-plans, verification-before-completion
• wshobson agents (75+ subagents) — clone from github.com/wshobson/agents, add to Claude Code config (do NOT use
  promptCopy

  /plugin marketplace add

  )
• Corey Haines marketing — copywriting, page-cro, email-sequence, cold-email, ad-creative, seo-audit, marketing-ideas
• mem0 (persistent memory) —
  promptCopy

  pip install mem0ai

Step 5: The CLAUDE.md template

The CLAUDE.md is your instruction layer — seven sections: Role, Voice rules, ICP, Connected tools, Skills, Folder convention, and Approval rules.

The Approval rules section is the most important for a back-office setup: define exactly which actions require human approval before Claude executes them. Anything involving money, client communications, or external publishing should require approval.

The 8 roles and sample prompts

Lead Gen: "Find 20 SaaS founders in [city] who posted about hiring challenges in the last 30 days. Export name, LinkedIn URL, company, and the post that triggered the search."

Sales: "Draft a follow-up sequence for the leads in leads.csv. 3 emails over 10 days. Use the pain points in their LinkedIn posts as the hook for each message."

Content Ideation: "Review my last 30 posts in content-archive.csv and identify the 3 topic clusters that drove the most engagement. Suggest 10 new post angles for each cluster."

Marketing: "Audit the homepage at [URL] against the ICP in my CLAUDE.md. List the top 5 conversion friction points and write replacement copy for each."

Accounting: "Pull all transactions from QuickBooks for last month. Categorize any uncategorized items, flag anything over $500 that doesn't match a known vendor, and produce a P&L summary."

Operations/SOPs: "Watch the Loom recording at [URL] of how I do the client onboarding call. Write a step-by-step SOP from it with decision points flagged."

Client Comms: "Read the last 10 emails in the [client name] thread. Draft a status update that covers progress, blockers, and next steps. Flag for my approval before sending."

Hiring: "Review the 15 applicants in applicants.csv against the job description in jd.md. Score each on required skills, write a 2-line summary, and rank them. Top 5 get a first-round invite draft."

Frequently asked questions

Does Claude actually replace these roles or just assist? Assist, primarily. Claude handles the repeatable, structured parts — research, drafting, categorization, summarization, first-pass analysis. It doesn't replace judgment calls or relationship management. The comparison to $6-12K is to full-time headcount plus SaaS; Claude gets you to 60-80% of that output at a fraction of the cost, with humans reviewing outputs before they go anywhere.

How do I handle the QuickBooks 100-day token expiry? Set a reminder 90 days after initial setup. When the token expires, Claude gets a 401 from the QuickBooks MCP. Re-run the OAuth flow in your QuickBooks developer console and update the token in your MCP config.

Which role delivers the clearest ROI fastest? Accounting and Lead Gen. Accounting because monthly categorization and P&L prep is pure time. Lead Gen because the research loop that takes a human half a day runs in under 10 minutes with Firecrawl and a tight prompt.
