Anthropic packaged the stuff every business owner drowns in, chasing invoices, closing the books, sorting leads, reviewing contracts, tax season, into one plugin with 30+ ready-to-run commands that plug into QuickBooks, PayPal, HubSpot and more.
Here is the full setup and every command it ships with.
What This Plugin Actually Is
A plugin is a pre-packaged set of skills for Claude. Instead of you explaining your business and typing the perfect prompt every time, the Small Business plugin ships the workflows already built: chase invoices, close the month, triage leads, review a contract, prep for tax season. You run them like commands. Type a slash, pick the job, done.
It works inside Cowork, the tab of the Claude apps built for longer, hands-on work. And it connects to the tools your business already runs on, QuickBooks, PayPal, HubSpot, Stripe, Square, Gmail, your calendar, so the commands work on your real numbers, not hypotheticals.
What "free" means here
The plugin itself costs nothing. You install it and every command is included. Plugins live on Claude's paid plans (Pro and up), so it is "free" the way an employee who comes with your existing subscription is free. Which, compared to hiring a part-time bookkeeper, it basically is.
The 60-Second Install
Step 1: Open Cowork. Open Claude (the desktop app or claude.ai) and click the Cowork tab.
Step 2: Customize, then Plugins. Open Customize, then click the Plugins tab.
Step 3: Browse and install. Click Browse plugins, search for Small Business, and hit Install. That is the whole setup.
Step 4: See everything it can do. Start a new chat and type / (or hit the + button). Search "small business" and you will see the full list of commands the plugin just gave you. Pick one and run it.
Best first command: /smb-onboard. It is the plugin's built-in trainer. It helps you connect your first two tools, runs one job to prove the value, and interviews you about your business so every other command gets smarter.
Connect Your Tools
The commands run on your real data through Claude's connectors. You do not need all of these, every command works with whatever you have connected and tells you what it is missing. But the more you plug in, the more of your week this thing takes over.
Connect them in Claude under Customize, then Connectors. Each one is a click plus a sign-in to that tool.
Tip: Start with just two: your accounting tool (QuickBooks) and your payments tool (PayPal, Stripe or Square). That unlocks the money commands, which is where most owners feel it first.
Every Command, Organized By Job
The plugin ships 30+ commands. Here is the full menu as of this writing, grouped by the part of your week they take over.
Money
Sales and leads
Customers
Marketing
Your week on autopilot
Paperwork and people
Do not memorize any of this. Typing / shows you the whole menu with descriptions, and you can also just say what you need in plain English ("who owes me money?") and the plugin routes you to the right command. The slash is a shortcut, not a requirement.
The Walkthrough: /invoice-chase
This is the command that sells the whole plugin. You are tired of chasing unpaid invoices every week. Type:
Here is what actually happens:
You are always the last click
The plugin drafts, organizes and stages, but money-touching moves, sending reminders, issuing a refund, anything a client sees, wait for your approval. It is a part-time hire that never sends anything you have not glanced at.
Tip: Make it a habit machine. Run /invoice-chase every Monday morning right after /monday-brief. Ten minutes, coffee in hand, and the two worst parts of your week are done.
Your First Week With It
Do not try all 30 commands on day one. One a day for a week and it is part of how you run the business.
If something does not work
Nine times out of ten it is a missing connector, and the command will tell you which tool it could not reach. Connect it under Customize, Connectors, and run the command again. For anything else, just ask Claude in the same chat. "Why didn't that work?" is a perfectly good prompt.
Your Action Plan
It is like hiring someone part-time, except it is already on payroll.
