Claude for Small Business: The Owner's Guide to Anthropic's Free Cowork Plugin

If you run a small business, you've probably used Claude to write an email or clean up a quote. What most owners haven't noticed is that Anthropic now ships a free Small Business plugin inside Claude Cowork that does something bigger: it runs the unglamorous back-office work — the cash position across a slow month, the missed-call list that turned into lost jobs, the month-end close, the campaign you keep meaning to send.

It's free, it's built by Anthropic, and it installs in about two minutes. This guide is the owner's manual: what it actually does, how to turn it on, and the one thing it won't do for you (which is where your profession's vault comes in).

💡 Start with the free owner's guide. We turned everything below into a free, copy-and-run download: Claude for Small Business — The Free Owner's Guide. It maps every plugin skill to the job it does, tells you which connector to switch on, and what to approve before Claude sends anything. Pay-what-you-want, $0 is fine. Get it free →

What "Claude for Small Business" actually is

It's a plugin — a bundle of pre-built skills — published by Anthropic inside Claude Cowork. Two terms worth pinning down, because the rest of this guide leans on them:

• Claude Cowork is the workspace inside Claude (desktop, web, and mobile) where Claude can run skills, connect to your tools, and read the files on your computer directly. You don't upload anything — you point Claude at a folder.
• A Cowork Project is that folder plus a set of instructions and a memory that persist between sessions. Think of it as your business's filing cabinet that Claude already knows how to read.

The Small Business plugin drops a set of ready-made business skills into that workspace. You trigger each one with a slash command — type / in a Cowork task and the installed skills show up. No prompt-writing, no setup wizard, no prompt library to maintain. Anthropic wrote the prompts; you just run them.

The mental model that makes the whole thing click: the plugin is the operator layer. It runs the business. It is not the practitioner layer — it doesn't do the regulated, reputation-on-the-line professional work that's specific to your trade. Hold that distinction; we come back to it.

Install it in two minutes

1. Open Claude and go to the Cowork tab.
2. Open Customize → Plugins (or the Marketplace).
3. Find the Anthropic & Partners section and install Small Business.
4. Start a new task and type / — the plugin's skills now appear in the list.

That's the whole install. The first time you run a skill that needs data — say, your cash position — Claude will ask to connect the relevant tool. You approve the connection once, and only for the tools you choose.

The jobs it does, grouped the way an owner thinks

The plugin's skills line up with the jobs a small business actually has. You don't need to memorize them — you run the one that matches what's on your plate this morning. Here's the map.

The job	What you run	What it needs
The front door — stop losing leads	Triage missed calls, web forms, and texts into a prioritized call-back list	Your inbox / phone log; Gmail or a CRM
Sales follow-up — work the pipeline	Build the call list, draft the follow-ups, flag who's gone cold	CRM (HubSpot) or a spreadsheet
Marketing — actually send the thing	Plan and run a campaign; turn it into social posts and graphics	Canva, your email tool
Finance — know your number	Cash-flow snapshot, AR (who owes you), invoice chase, month-end close	QuickBooks, Stripe, PayPal, or Square
Customers — keep them happy	Customer sentiment pulse, complaint handling, ticket triage	Email, support inbox
Reporting — the Monday brief	A weekly brief that pulls pipeline, cash, and what needs your attention	Whatever you've connected above
Contracts & hiring — the occasional heavy lift	Plain-English contract review; a structured hiring plan	A document; your notes

Representative skills you'll see once it's installed include things like /business-pulse, /lead-triage, /call-list, /run-campaign, /cash-flow-snapshot, /invoice-chase, /close-month, /customer-pulse, /contract-review, and /friday-brief. The exact roster shifts as Anthropic updates the plugin — the slash menu in your own Cowork is always the source of truth, and the free owner's guide keeps a current job-by-job map.

The connectors are the unlock

A skill is only as useful as the data it can reach. The plugin connects to the tools a small business already runs on, through Cowork connectors:

• Money — QuickBooks, Stripe, PayPal, Square
• Customers & marketing — HubSpot, Canva
• The everyday stack — Gmail, Google Drive and Calendar, Microsoft 365, Notion, Slack

Enable only what you use. Until you connect a tool, the skills still work on files you point Claude at — you just lose the live data. The first real "oh, this is different" moment for most owners is the first cash-flow snapshot that pulls the actual numbers from QuickBooks instead of a guess.

The trust pattern: Claude drafts, you approve

The thing that makes this safe to run on a real business is the boundary baked into how you use it: Claude drafts; a human approves anything customer-facing, financial, or contractual before it ships. The campaign email gets written, but you send it. The invoice reminder gets drafted, but you release it. The contract gets reviewed and flagged, but you decide.

Set that rule once in your Project's instructions ("draft, don't send; flag anything that touches money, a customer, or a contract for my approval") and every skill inherits it. That single line is the difference between a helpful assistant and an automation you're nervous about.

Where the plugin stops — and your vault begins

Here's the honest limit. The Small Business plugin is profession-neutral by design. It runs the business beautifully. It does not do the regulated, voice-sensitive, reputation-defining work that's specific to your trade — and it doesn't carry the guardrails your field requires.

A few examples of what the operator layer leaves on the table:

• A real estate agent needs listing copy that sells and never trips Fair Housing language. Generic AI cheerfully writes "perfect for a young family" into a description and walks you toward a complaint.
• A bookkeeper needs a hard CPA boundary so the draft never drifts into tax advice.
• A loan officer needs TILA/RESPA/ECOA-aware language on every borrower comm.
• A photographer needs AI-edit-aware contract clauses that generic templates miss.

That's the practitioner layer — and it's exactly what the profession-specific vaults are built for. Each one is a set of skills tuned to how the work is actually practiced in that field, with the compliance guard running passively in the background.

🧭 The two-layer setup, start to finish. Install Claude for Small Business (free) to run the back office, grab the free owner's guide to master it fast, then add your profession's vault for the regulated, voice-sensitive work the plugin won't touch. Find the vault for your profession →

The operator layer is the OS. The vault is your professional license. Most owners run both.

Start this week

1. Install the plugin. Cowork → Customize → Plugins → Anthropic & Partners → Small Business. Two minutes.
2. Make a Project for your business. Point it at a folder with your real files and write the one-line approval rule into the instructions.
3. Run one finance skill and one front-door skill. A cash-flow snapshot and a missed-call triage will both pay for the setup in the first sitting.
4. Grab the free owner's guide so you're not guessing which skill does what.
5. When the back office is humming, add your profession's vault for the work the plugin can't do.

The plugin is free and it's from Anthropic. There's no reason not to have it running by the end of the week.
