Kitchen Automation
That Keeps Running
Even When the Internet Doesn’t

Rest-O-Pi OS is a Shopify-native ordering and kitchen automation platform for independent Australian restaurants, cafés, and retail shops. Orders flow from every channel straight to your kitchen — printed and displayed with zero manual steps.

The market opportunity

The AU hospitality POS market has a gap nobody fills

Enterprise platforms serve chains. Budget apps serve the smallest cafés. Independent SMBs on Shopify — hundreds of thousands of them — have no kitchen-native solution built for them. Rest-O-Pi OS is that solution.

Enterprise zone

Complex & expensive

Multi-site chains only. Long setup. Enterprise lock-in.

Unserved gap — Rest-O-Pi OS

Independent SMBs on Shopify

Restaurants, cafés, and retail shops who already use — or plan to use — Shopify as their commerce platform.

Rest-O-Pi OS fills this gap

Budget zone

Simple but insufficient

Retail-first. No kitchen print. No offline mode. Inconsistent reliability.

Why Rest-O-Pi OS

Three things no competitor combines

Shopify-native

Built on Shopify's battle-tested payments, orders, and inventory infrastructure. No parallel systems, no manual reconciliation, no data split across platforms. One source of truth for your entire operation.

Local-first — built for real-world outages

Your Raspberry Pi server runs on your restaurant’s local network, so kitchen printing and display continue even during internet dropouts. Orders already placed keep flowing — your kitchen doesn’t stop when the connection does.

Built for partners

Designed for IT agencies and Shopify partners to deploy, customise, and scale across multiple clients. A clear path to white-label and reseller distribution as you grow.

Full platform

Everything your kitchen needs, nothing it doesn't

Rest-O-Pi OS is a complete, production-grade system — not a collection of third-party apps stitched together. Every feature is built to work together reliably in a real kitchen environment.

Ordering channels

  • Shopify online store — mobile-first, no app install required
  • QR code dine-in ordering — scan at table, order and pay instantly
  • Staff counter POS — works with Shopify POS extension
  • Order type detection — Dine-in, Takeaway, Delivery automatically identified

Technical overview

Built on proven infrastructure

Rest-O-Pi OS uses Shopify as its commerce engine — meaning payments, PCI compliance, product catalog, and inventory are all handled by one of the world's most trusted platforms. We build the restaurant layer on top.

The flow

From order placed to kitchen ticket — in under 10 seconds

1
Customer places an order

Via your Shopify website, a QR code scanned at their table, or a staff member at the counter. All channels feed into one unified queue.

2
Shopify fires a webhook instantly

The moment an order is created, Shopify sends a secure, HMAC-signed notification to your Rest-O-Pi OS server. Fraudulent requests are blocked automatically.

3
Kitchen ticket prints automatically

The Raspberry Pi server formats the order with all items, modifiers, table number, and special instructions — then sends it to your Epson thermal printer. No one clicks anything.

4
KDS displays the live order board

The kitchen iPad shows all active orders colour-coded by status. New orders trigger a sound alert. Staff tap to move orders from New → Preparing → Ready.

5
Fulfilment synced to Shopify

One tap on the KDS marks the order fulfilled in Shopify via the Admin API. Inventory, reports, and customer notifications all update in real time.

6
Remote monitoring if anything needs attention

Raspberry Pi Connect lets you SSH into the server from any browser, anywhere. Check logs, restart the server, or update settings — no need to be on-site.
