Decision snapshot

Is this worth validating?

Build this if

The cafe has repeat pickup demand, a stable menu, and staff capacity to maintain a separate paid-order queue.

Avoid this if

The primary need is delivery, multi-location inventory, event management, or customer messaging.

Validate first

Run fifty real or staff-simulated pickup orders through the morning rush and verify slot capacity, modifier accuracy, preparation order, and one-time loyalty earning.

Problem and target customer

Why this exists

Customer problem

Regulars wait in the same line as complex walk-in orders, while phone pre-orders lose customization details and disrupt the barista queue. Paper stamp cards are easy to forget and do not connect rewards to completed purchases.

Who pays

Independent neighborhood cafes with repeat morning traffic, a stable menu, and staff who can maintain a dedicated order-ahead preparation queue.

Business model

Monthly software license for one cafe location plus payment-processing fees charged by the connected provider.

Editorial note

The cafe needs a reliable paid-order queue before it needs chat, events, or sophisticated gamification. Pickup capacity is the operational promise that connects the customer experience to what baristas can actually prepare.

Rewards should follow collection rather than checkout. That boundary prevents abandoned, cancelled, or refunded purchases from inflating the bean balance and gives staff a clear final action.

A beta should be judged during a rush: modifiers must survive payment, the queue order must be understandable at a glance, and delayed provider events must recover without duplicate drinks or credits.

Product goal

Who it serves and what it must change

Target user
A repeat cafe customer ordering before arrival and the barista responsible for preparing paid orders in pickup order.
Problem
Phone orders omit modifiers and paper rewards do not align with fulfilled purchases, while staff lack a clear preparation sequence.
Measurable outcome
A customer can place and collect a customized paid drink; staff can advance it through preparation, and loyalty credit appears exactly once only after collection.

Primary flow

  1. The customer selects available items, valid modifiers, and a pickup slot with remaining capacity.
  2. Checkout creates a pending order; a verified payment webhook moves it to Paid and places it in the staff queue.
  3. A barista starts preparation and marks the order Ready, which updates the customer's status.
  4. Staff verify the pickup code and mark the order Collected.
  5. Collection creates one loyalty earning entry; a future eligible cart may redeem the configured reward before payment.

Business rules

  • Prices and modifier choices are snapshotted on OrderItem so later menu edits do not alter paid orders.
  • Only a verified provider webhook may move Checkout pending to Paid; repeated events are idempotent by provider event ID.
  • A pickup slot cannot accept paid orders beyond capacity, and capacity is checked again before checkout creation.
  • Beans are earned exactly once when an eligible paid order becomes Collected; cancelled or refunded orders do not earn them.
  • Reward redemption cannot make the total negative and creates a separate immutable debit entry.

Architecture and data flow

Components, integrations, and controls

Customer web app

Render menu, customization, checkout return, order status, and bean wallet.

Staff console

Manage availability, pickup capacity, and valid order transitions.

Application API

Price carts, reserve slots, create checkout sessions, and enforce loyalty rules.

PostgreSQL database

Store catalog, order snapshots, payment events, status history, and loyalty ledger.

Webhook worker

Verify and process payment and refund events idempotently.

Integrations

  • Stripe Checkout and webhooks for payment and refund status
  • Transactional email for receipts and pickup notices
  • Optional Make webhook for bounded staff-volume alerts

Data flow

  1. The server prices a validated cart from active menu records and reserves a pickup slot for a short checkout window.
  2. Stripe completes payment and sends a signed event; the webhook stores the event and activates the order once.
  3. Barista actions append status timestamps visible to the customer status page.
  4. Collection writes the loyalty earning in the same transaction as the final order transition.

Failure handling

  • Release an expired slot reservation when checkout is abandoned.
  • If payment succeeds before the app receives the webhook, show Payment confirming and reconcile from the provider event.
  • If Ready notification fails, keep the order Ready and let staff resend without changing preparation state.

Security

  • Verify payment signatures, use idempotency keys, and never store raw card details.
  • Protect staff actions with role checks and short sessions on shared tablets.
  • Use unguessable status tokens and reveal only the minimum order details on customer links.

Rate limits

  • Limit checkout creation by customer, device, and pickup slot.
  • Throttle status polling and switch to slower intervals after collection.
  • Deduplicate payment events permanently and cap notification retries.

Deliverables and acceptance

Definition of done for the MVP

Deliverables

  • Responsive menu, customization, cart, checkout return, status, and bean wallet
  • Tablet barista queue and menu availability controls
  • Schema, migrations, payment event ledger, and sample menu
  • Stripe integration with slot reservation and refund states
  • Tests for pricing, capacity, idempotency, transitions, and loyalty

Acceptance criteria

  • A customer can buy a customized item only from the currently valid options and see the final price before payment.
  • Two simultaneous checkouts cannot oversell the last space in a pickup slot.
  • Repeating the same payment webhook creates one Paid transition and one queue ticket.
  • Beans appear once after Collected and never for an order cancelled before pickup.
  • When a payment confirmation is delayed, the customer sees a non-final state and the later webhook activates the original order without duplication.

Recommended stack

Enough technology for the first version

Web application

Next.js and Tailwind CSS

Deliver fast mobile ordering and a tablet queue from one codebase.

Data and auth

PostgreSQL with Auth.js

Keep catalog rules, capacity, order history, and staff permissions consistent.

Payments

Stripe Checkout

Handle card entry outside the app and expose signed payment and refund events.

Email

Resend

Send receipts and pickup notices with observable delivery status.

Media

Cloudflare R2

Serve optimized menu images without bloating relational backups.

Why this is sufficient

Order integrity depends on server-side pricing, capacity checks, and idempotent payment events. The loyalty ledger belongs in the same relational boundary so collection and earning cannot drift apart.
