Contractor‑Ready Microfeature Kit: Deliver These Exact Artifacts So a Contractor Ships a Paying Flow in Two Weeks

A one‑page PRD is the single source of truth. Keep it lean: goal, success metric, target user, out‑of‑scope items, UX flow (step list), backend constraints, and the release definition (how we’ll declare the feature live). Use a small, fixed template so contractors don’t chase vague requirements.

Make the success metric a concrete paid action (e.g., “first successful charge of $X within 60s of checkout”) and attach the telemetry event key that will prove it. Under constraints list required third‑party services (Stripe, Auth provider, CMS), minimum browser/platform support, and any data residency or compliance notes.

Turn every acceptance criterion into a testable Gherkin scenario (Given/When/Then) so the contractor can demo with confidence and QA can automate or copy/paste to Cucumber/Cypress. Each scenario should map to a single observable outcome (UI message, API response code, or telemetry event).

Provide positive and key negative cases: successful payment, card declined, invalid promo code, and network failure. Include exact data to use (test user email, product id, test card numbers). This removes guessing and lets the contractor script demo flows and attach automated checks.

Provide a ready‑to‑paste JSON‑LD snippet for the product/offer so the contractor can drop it into the marketing page or demo HTML. Use the schema.org Product + nested Offer pattern and include price, currency, availability, sku/id, and url. This helps SEO, merchant tools, and any pricing displays in previews.

Keep one canonical snippet for the microfeature (include a priceValidUntil when relevant). If the paid flow uses subscriptions, include the best matching schema (Offer with priceSpecification or Product with recurringOffer where supported). Provide the final payload and the exact HTML location where it should be added.

Deliver Figma screens exported as production‑ready slices: PNG/SVG assets, a compressed sprite or asset pack, and a short style token file (colors, fonts, spacing). Add an assets manifest listing file names, intended HTML/CSS class or component name, and where each asset is used in the flow.

Include a clickable prototype link and 1–2 annotated screens that show the exact copy strings and dynamic placeholders (e.g., {{price}}, {{user.name}}). If there are responsive variants, include only the breakpoints your contractor must support for the demo to reduce scope creep.

Give a payment stub that contains the exact API endpoints, test keys, webhook endpoints (or a note that webhooks may be stubbed), and test card numbers. For Stripe or similar, include the customer and product ids you already created in test mode so the contractor can simulate a charge that mirrors production behavior.

Specify what counts as a successful charge (authorization+capture vs. only authorization), whether to create invoices, and the post‑payment UX (receipt email, redirect). If refunds or proration are out of scope for the demo, state that explicitly.
