Build an E-commerce Store with AI Execution Map — Roadmap, Workflows & Tools

Step 1 of 10

Define the store

Requirements for a single-vendor catalog, cart, checkout, and orders.

Phase Define & Scope

Workflow AI Product Requirements Workflow Turn a fuzzy business need into requirements a team can build from — interrogate the need into concrete requirements, shape them as user stories, and write the PRD. Resource Product Requirements Assistant Turn a rough feature idea into a structured requirement: problem statement, acceptance criteria, and what's explicitly out of scope. Tool System Prompt Generator Build structured system prompts from role, tone, constraints, and model target.

Step 2 of 10

Model the catalog and orders

A products/variants/inventory/cart/orders schema.

Phase Design

Workflow AI Database Design Workflow Design a schema on its data, not a hunch — model the entities and relationships, set the constraints that protect integrity, plan indexes around real queries, then document the schema and migration. Resource Schema Design & ERD Prompt — Entities, Relationships, and Keys Turn product requirements and key entities into an ERD-ready schema spec: tables, fields, primary and foreign keys, relationships with cardinality, indexes, and constraints — with the modeling gaps named as open questions. Tool SQL Optimization Prompt Build evidence-based SQL optimization prompts — goal, platform, and the evidence you have turn into a query tuning contract.

Step 3 of 10

Design the store API

An API contract for catalog, cart, checkout, and orders.

Phase Design

Workflow AI API Design Workflow Design an API on its contract instead of discovering it endpoint by endpoint — model the resources, design the endpoints and payloads, pin the contract, then review it before code locks it in. Resource Turn a JSON Schema into a Prompt You have the schema — fields, types, requirements. The translation into a prompt the model actually follows: schema lines, realistic example, and validation rules. Tool JSON Output Prompt Builder Build prompts that return structured data — JSON first, with YAML, XML, and CSV modes — parseable every time.

Step 4 of 10

Design the storefront

A component system for product pages, cart, and checkout.

Workflow AI UI & Component Design Workflow Structure a UI so it stays consistent as it grows — inventory the screens, break them into reusable components, specify the component system and its rules, then review the structure for drift. Resource Design System Spec Prompt — Components, States, and Accessibility Turn UI requirements and component needs into a design-system spec: a component inventory with states, variants, responsive behavior, accessibility requirements, microcopy rules, and developer handoff notes. Tool Markdown Output Builder Build prompts that produce documents in a fixed structure — headings, sections, and tables.

Step 5 of 10

Add customer accounts

Customer accounts and store-owner admin (single-vendor, no seller signup).

Phase Build & Refine

Workflow AI Auth & Identity Workflow Design access control before you build it, not after a breach — choose the authentication approach, model the roles and permissions, review the design for gaps, then document the identity model. Resource Authentication Strategy Prompt Choose how users prove who they are — sessions vs tokens, passwords vs passwordless, SSO and MFA — decided on your real constraints, not the default tutorial. Tool Role Prompt Generator Generate expert role prompts — perspective, responsibilities, and decision criteria, not just "act as".

Step 6 of 10

Wire payments and fulfillment

Payment, shipping, and notification integrations wired reliably.

Phase Build & Refine

Workflow AI Integration & Webhook Workflow Connect systems so they don't break each other — map the integration boundaries, design the event and webhook contracts, plan retries and failure handling, then document the integration. Resource Turn a JSON Schema into a Prompt You have the schema — fields, types, requirements. The translation into a prompt the model actually follows: schema lines, realistic example, and validation rules. Tool Multi-Step Prompt Builder Break a big goal into a sequential prompt workflow — each step with an objective, prompt, and expected output.

Step 7 of 10

Run a security review

The checkout, account, and order paths reviewed for vulnerabilities.

Phase Build & Refine

Workflow AI Security Review Workflow Review code for what an attacker would do, not just what tests catch — anchor the model as a security engineer, run a threat-focused review, then back the findings with auth and input tests. Resource Security Code Review Prompt Twelve security checks — injection, auth, secrets, SSRF, privilege escalation — reviewed the way an attacker would read the code. Tool Code Review Prompt Generator Generate code review prompts for any scope — snippet, file, diff, or full pull request — with focused review rules.

Step 8 of 10

Lock behavior down with tests

Tests covering the cart, checkout, and order paths.

Phase Build & Refine

Workflow AI Test Generation Workflow Build a test suite that fails for real reasons, not green decoration — coverage across unit, integration, and edge cases, then a review for the gaps. Resource Unit Test Prompt — Isolation Done Right Mock the dependencies, test the business logic, one behavior per test — the unit testing contract that bans plumbing tests. Tool Test Case Prompt Generator Build test generation prompts — unit, integration, or E2E — with framework modes and edge-case coverage rules.

Step 9 of 10

Ship the store

The store shipped with a rollback path and checkout monitoring.

Phase Ship & Validate

Everything you need for this step Download full path PDF

Workflow AI Deployment & Release Workflow Cross the gap between 'tests pass' and 'safe in production' — assess release readiness, plan the deploy and its rollback, and set up the monitoring and launch checks before you ship, not after. Resource Production Readiness Review Prompt SHIP or DO NOT SHIP: twelve checks on failure modes, observability, rollback, and load — the review that happens before the incident. Tool Markdown Output Builder Build prompts that produce documents in a fixed structure — headings, sections, and tables.

Step 10 of 10

Validate the product with real evidence

The shipped outcome measured against its success signal, with an iterate, pivot, or scale decision documented.

Phase Ship & Validate

Everything you need for this step Download full path PDF

Workflow AI Product Validation Workflow Find out whether the thing you shipped actually worked — define the success metric, plan the measurement, classify the real evidence, then render a verdict and an iterate / pivot / scale decision. Resource Product Validation Report Prompt Consolidate the whole validation into one shareable report — the success metric, the evidence, the hit / partial / miss verdict, and the iterate / pivot / scale decision, in a form the team and stakeholders can act on. Tool Markdown Output Builder Build prompts that produce documents in a fixed structure — headings, sections, and tables.
