Grace of Cows — Farm-to-Home A2 Dairy Subscriptions

Grace of Cows delivers fresh, chemical-free A2 milk to homes every morning. The business is deceptively hard software: thousands of standing daily orders, narrow pre-dawn delivery windows, pauses and top-ups, and payments that must reconcile to the day. We built the subscription and logistics platform that turns a herd and a delivery fleet into a dependable daily service.

A Next.js storefront and customer app sit over a custom Node.js backend with MongoDB as the distributed store for subscriptions, orders and delivery state. A nightly engine materializes the next morning's order book from active subscriptions (accounting for pauses, quantity changes and holidays), then a route-optimization layer against a maps API sequences deliveries per rider for the fastest pre-dawn run. Payment gateways settle prepaid wallets and reconcile automatically.

The window is unforgiving — everything must be delivered fresh in a few pre-dawn hours, every day, with no margin to re-run. Orders mutate until cut-off (customers pause, add curd, change quantity), so the order book, the routes and the billing all have to be correct at 4am without a human rebuilding spreadsheets.

• A high-frequency subscription engine that regenerates the daily order book from mutable standing orders, honouring pauses, top-ups and holiday calendars.
• Route-optimization that sequences each rider's stops against live map data for the fastest morning distribution run.
• A CRM lifecycle pipeline tracking every customer from trial to retention, surfacing churn signals before they cancel.
• Automatic payment reconciliation so prepaid wallets, deliveries and invoices agree to the day with no manual bookkeeping.
