Build the New-Buyer-To-Second-Purchase Flow Against Your Hero SKU Set (Claude Cowork Self-Install Kit)

Turn first-time buyers into second orders without ever discounting your way there.

You get someone to buy once and then never hear from them again. You keep meaning to build a proper post-purchase sequence, but every time you sit down to do it, something more urgent takes over.

The leak isn't your product. It's that the follow-up depends on you remembering each new buyer, so the second order only happens by accident.

What this kit does

On a customer's first order, the kit fires a three-touch flow that recommends three hero SKUs from a sibling category they didn't buy, hitting at day 7, day 21, and day 45. It pushes the repeat purchase rate without leaning on a discount, running across Shopify and Klaviyo. The second-purchase ask happens every time, on schedule, instead of when you get around to it.

What you can expect

First-time buyers convert to repeat customers at a higher second-purchase rate within 45 days of their first order, and manual follow-up on new buyers disappears entirely. The three-touch sequence runs without you touching it after setup.

One illustration: 300 new buyers a month, a conservative 4-point lift in second purchases, at a $100 average order, is about $1,200 a month in repeat revenue, roughly $14,400 a year. Your new-buyer volume, repeat lift, and order value set the real number.

Figures are illustrative, not a guarantee. Actual results depend on your business, tools, and usage.

Who it's for

Built for e-commerce owners and operators who win the first order and want the second without discounting. This is a Claude Cowork self-install kit you run yourself.

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 sits at the top tier because of what a second purchase is worth, not the setup time. The flow lifts repeat revenue across every new buyer at no extra acquisition cost, and that recovered revenue compounds on every cohort from here on.

What you'll need (not included)

The kit is the workflow, the prompts, and the setup guide. It does not include the tool subscriptions it runs on. You'll need your own Claude with Cowork, Shopify, and Klaviyo accounts. Those are billed by the tools themselves, not by us.

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.

How to install this kit

Connect Shopify and Klaviyo at claude.com/connectors and authorize each account. Open the kit in Claude Cowork and run the included prompt. Step-by-step instructions ship inside every kit, so you're never guessing. See How Self-Install Kits Work for the full walkthrough.

Install once, not every month

If you've been pricing post-purchase and repeat-purchase apps, this is the install-it-once alternative. You build the flow yourself and keep it, with no monthly app fee stacked on top of Klaviyo. Add it to your cart, open it in Claude Cowork, and build your second-purchase flow this week.
