Indie Skincare Brand Storefront with Routine Builder

Problem and target customer

Why this exists

Customer problem

Shoppers can compare individual products but still struggle to choose compatible steps, apply them in the right order, and keep the total within budget.

Who pays

Independent skincare brands with a small curated catalog and customers who need guided product selection rather than clinical advice.

Business model

Direct-to-consumer product sales

Editorial note

The routine builder is a merchandising tool, not a diagnostic engine. Its credibility comes from visible product attributes, explicit exclusions, and a shopper's ability to edit the recommendation.

The most useful beta signal is whether guided selection improves confidence before checkout. Replenishment, loyalty, and generated advice should wait until the catalog rules prove understandable.

Product goal

Who it serves and what it must change

Target user: A first-time shopper at an independent skincare brand who wants a simple morning and evening routine.
Problem: Product pages explain individual items, but shoppers still have to decide which products work together, in what order, and within their budget.
Measurable outcome: A test shopper can answer the quiz, understand each routine step, remove or swap an item, and reach hosted checkout without asking for product-order help.

Core entity outline

Entities and business rules

Product

Defines a sellable skincare item and the tags used by the routine matcher.

Fields: name, product_type, price, inventory_status, concerns, skin_feel_tags, sensitivity_flags, usage_period, sort_order
Relations: Appears in RoutineItems, Appears in OrderItems

QuizResponse

Stores one shopper's answers and consent to save them.

Fields: skin_feel, primary_concern, sensitivity, routine_size, budget_band, created_at
Relations: Produces one Routine

Routine

Records a generated and shopper-edited set of ordered steps.

Fields: quiz_response_id, status, total_price, version
Relations: Has many RoutineItems

RoutineItem

Places a selected product in a morning or evening sequence with a match explanation.

Fields: routine_id, product_id, period, step_number, match_reason, selection_source
Relations: Belongs to Routine, References Product

Order

Tracks the Stripe Checkout result without storing card data.

Fields: checkout_session_id, status, currency, subtotal, customer_email
Relations: Has many OrderItems, May reference a Routine

Business rules

Every suggested item must be active, in stock, and allowed by the shopper's sensitivity answer.
Routine steps sort by configured usage order, not by price or popularity.
A swap must satisfy the same product type and exclusion rules as the replaced item.
Price and stock are rechecked before checkout session creation.
Content must use cosmetic guidance language and never diagnose a condition.

Architecture and data flow

Components, integrations, and controls

Commerce web app

Serves catalog pages, quiz steps, routine results, cart, and saved order status.

Routine rules service

Matches complete quiz answers to tagged products and produces ordered, explainable steps.

Catalog database

Stores products, compatibility tags, quiz answers, routine versions, and order references.

Checkout adapter

Creates Stripe Checkout sessions and verifies payment webhooks.

Integrations

Required: Stripe Checkout for hosted payment and signed order-status webhooks.
Product images may use the deployment platform's object storage or CDN.
Optional fulfillment automation can forward paid-order details to an existing sheet or inbox after the webhook is verified.

Data flow

The quiz stores a complete QuizResponse or remains local until the shopper submits.
The rules service filters active products, applies exclusions, orders the selected steps, and writes a Routine.
Shopper edits create a new routine version and the cart reads current product prices.
The server creates a Stripe Checkout session using server-side catalog data.
A verified webhook changes the Order from pending to paid or failed.

Failure handling

If no valid routine exists, explain the conflicting answer and offer catalog browsing instead of inventing a result.
If stock changes before checkout, return the shopper to an updated cart with the unavailable item identified.
Ignore duplicate Stripe webhooks by event ID and expose a payment-status refresh action.

Security

Never accept product price or payment status from the browser.
Keep payment card data in Stripe-hosted Checkout.
Require explicit consent before associating quiz answers with an account.
Escape catalog content and restrict catalog editing to brand staff.

Rate limits

Limit quiz submissions per session to reduce spam.
Rate-limit checkout session creation by shopper and cart hash.
Cache public catalog reads while invalidating on product changes.

Deliverables and acceptance

Definition of done for the MVP

Deliverables

Responsive storefront and catalog
Five-question routine quiz
Deterministic matching rules with editable results
Stripe Checkout and webhook handling
Seed catalog and rule-maintenance guide

Acceptance criteria

The same catalog and quiz answers produce the same ordered routine.
A sensitive-skin exclusion prevents a tagged product from appearing.
Changing a routine item updates the kit total from current catalog prices.
An out-of-stock item blocks checkout and points to the affected step.
A repeated payment webhook does not create a second order.

Recommended stack

Enough technology for the first version

Storefront

Next.js and TypeScript

Supports fast catalog pages and an interactive multi-step quiz in one application.

Catalog and routines

Postgres

Relates quiz answers, product tags, routine versions, and orders with enforceable constraints.

Payments

Stripe Checkout

Keeps payment collection hosted and returns signed order events to the app.

Media

S3-compatible object storage

Serves optimized product images without placing binary assets in the database.

Why this is sufficient

A deterministic rules layer is easier for brand staff to audit than an LLM and keeps every recommendation grounded in maintained product attributes; hosted checkout narrows payment scope.
