Master build prompt for a D2C subscription box
The build prompt for D2C subscription e-commerce: monthly box plans, a preference quiz, delivery schedules and churn-reduction flows.
Built for: D2C brands and subscription box startups
In the subscription box business, the technical challenge isn't the catalog; it's recurring billing and the logistics calendar. Skip-a-month, address changes, box personalization and cancellation-prevention flows drive most of the revenue.
The prompt explicitly defines the subscription lifecycle (trial → active → paused → canceled) and the emails and notifications each transition triggers.

FAQ
How do recurring payments work?
Payments sit behind an abstraction layer: Stripe for global customers, with Iyzico's card storage and subscription product as the default when you sell in Turkey.
Does the prompt include a churn-reduction flow?
Yes. The Growth Architect persona writes a cancellation-reason survey, a pause option and a win-back campaign into its task block.
Which tools can I paste the generated prompt into?
Claude Code, Cursor, Windsurf, v0, Lovable, Bolt and ChatGPT. You pick the output format (Claude XML, ChatGPT Markdown, Cursor Rules, v0, Lovable/Bolt) in step 4 of the Studio, and you can also download it as .cursorrules or CLAUDE.md.
Is it free?
Yes. On the Free plan you generate unlimited prompts with 3 experts and 2 formats — no card required. 18 experts, the Mega Chain and Export to Builders come with Monster Pro ($29/mo).
