Crately | AI B2B Food Supplier Flutter App (Admin Panel + Customer & Driver, Next.js + Postgres)

Crately is a 3-in-1 bundle — a Next.js admin panel + customer web + REST API, a Flutter customer app, and a Flutter driver app. Single supplier, many restaurant customers. Eight AI features ship enabled out of the box.

Wholesale ordering, B2B-grade

• Credit terms — NET-15, NET-30, COD, prepaid; per-account configurable
• Delivery cutoff times per zone, owner-approval threshold for large orders
• Standing orders — recurring weekly patterns, auto-submit with reminder
• Multi-location restaurant chains — chains pick a location at checkout
• Quality credits applied to invoices (not refunds)
• FIFO/FEFO inventory batches with expiry awareness

5 AI hero features + 3 secondary

• AI Order Predictor — pre-filled next order from history + seasonality
• AI Recipe → Order Converter — chef pastes a recipe, AI returns priced ingredients
• AI Quality Audit — driver photos analysed on delivery; flagged items auto-credit
• AI Smart Replenishment — nightly demand forecast becomes a draft purchase order
• AI Credit Risk Monitor — flags accounts before they go bad based on AR + payment patterns
• AI Substitution Engine — picks 3 closest in-stock alternatives priced for the customer
• AI Demand Insights — weekly Sunday digest (top movers, anomalies, pricing opportunities)
• AI Description Generator — admin generates product copy from a few keywords

Realtime delivery tracking

Driver streams GPS every 15s. Customer’s order screen shows a live Google Map with the driver pin moving — Pusher Channels for sub-second updates, polling fallback for graceful degradation.

Stripe pay online

One-tap “Pay $X online” on open invoices. Stripe Checkout opens in the system browser, returns to the Flutter app via deep link (crately://), invoice flips to PAID via webhook.

Real KPI dashboard

Today’s orders + revenue, 7-day chart, AR aging buckets, AI alerts, top accounts this month, recent activity feed — every section pulls from the live data, every card deep-links to its detail screen for fast triage.

FCM push notifications

Order status transitions + Stripe payment success automatically push the right person. Tapping a notification deep-links into the app on the right screen.

Industrial Harvest design system

Material 3 token set with Deep Forest Green primary + Sage Cream surface. Change one CSS variable and one Dart variable to rebrand the whole app. Sora + JetBrains Mono typography. Custom SVG mark + raster pipeline regenerates every platform icon size with one command.

B2B credit + AR aging

Invoices issued per order, due-date computed from snapshotted credit terms, 5-bucket AR aging dashboard, statements PDF (React-PDF), payments table with Stripe + manual reconciliation, quality credits applied to oldest open invoice.
