Sync Square Payments to Live Inventory Automatically (Claude Cowork Self-Install Kit)

Know what sold out and what to reorder before a customer is the one who tells you.

Right now you find out something's gone when a customer asks for it, and by then the sale is already lost. Sunday evenings go to matching Square receipts against a spreadsheet, and things still slip through.

That gap isn't down to effort. Your sales and your stock count live in two places that never talk, so every reconciliation is a manual re-entry job.

What this kit does

This kit connects your own AI agent to your Square account so every sale you ring up can be read against your catalog on demand. Ask what sold this week and what's running low, and your agent maps transactions to stock and surfaces reorder candidates ranked by velocity before you hit zero. The Sunday reconciliation shrinks to a short review you can do with coffee in hand.

What you can expect

You recover the 2 to 4 hours a week that manual stock reconciliation and end-of-week sales review used to eat. Low-inventory items surface while there's still time to reorder, so fewer sales walk out the door on a stockout. You walk into the week knowing what to order instead of guessing from last week's totals.

Who it's for

Local service business owners, e-commerce operators, and solopreneurs who run sales through Square and reconcile stock by hand. This is a self-install kit you run yourself with your own AI agent, built for Claude Cowork first.

What's included

Skip building from scratch. No coding. You get the complete kit your own AI agent reads, sets up, and runs for you, step by step:

• A Start Here guide, so you know exactly what to open first
• The agent install instructions, the part that lets your own AI agent stand the workflow up for you
• A guided setup that interviews you about your business, so the workflow fits how you actually work
• Workflow Briefing: the plan, the inputs, and what done looks like
• Task List your agent follows to build it
• MCP Connection Guide for the tools involved
• Tool Setup notes for accounts, keys, and permissions
• Prompt Library, including the ready-to-run prompt for this workflow
• Troubleshooting and maintenance guide for the common snags
• A Next Steps and Roadmap, so you know what to automate next once this one is running
• A Run Guide you keep, so you can run it any time with no setup again

It's a small kit, and it earns its keep on repetition: run it every Monday morning and the reconciliation hours you save add up across the whole year.

What you'll need (not included)

The kit is the workflow, the prompts, and the setup guide. You bring your own Claude with a Cowork account and your own Square account, which works on Square's free tier.

You'll also need your Claude account on Cowork's Pro plan or higher, so your agent can connect your tools and use the most capable model while it installs the workflow.

Not on Claude? The kit is plain files that describe what to achieve rather than which buttons to press, so a capable AI agent on another platform, like ChatGPT Work, can follow the same steps. If anything doesn't map to your setup, email support and we'll get you working.

How to install this kit

Open your agent in Claude Cowork and point it at your kit files. Connect Square at claude.com/connectors, grant read access to your transactions and catalog, then run the prompt to see your first reorder list. For the full picture, see How Self-Install Kits Work.

Install once, not every month

This is an inventory workflow you own, not an app that charges you every month to watch your own stock. Install it once and run it every week for as long as you sell. Add it to your cart, open it in Claude Cowork, and catch your next stockout before a customer does.
