The most reliable online ordering system in the UK, and how to check

Updated 13 Nov 2026. Every provider fact below comes from that provider's own pages, read on 12 or 13 November 2026 (each source and its date is listed at the end).

Every ordering system says it is reliable. Almost none publishes a number you can hold it to, and that is the honest starting point of this guide. We could not find an uptime percentage or a service level agreement (SLA) on the public pages of any provider listed here, except that Storekit lists "Contracted SLAs" on its Enterprise plan. We have not made up a figure for Chefzi or anyone else, and nobody can honestly name "the most reliable" system from public pages alone. What you can do is compare what each provider commits to in writing, how the system behaves when the internet or the kitchen tablet fails, and how fast a human answers. Chefzi wrote this guide and is one of the providers covered, so we state Chefzi's limits as plainly as the others.

The short answer

• No provider here publishes an uptime figure. Treat any uptime percentage you are quoted as something to ask for in writing, with what happens if it is missed.
• Reliability on a busy night is mostly about failure behaviour: does the order keep ringing until someone answers, what happens when the device or the internet drops, and can you keep trading.
• Support hours differ a lot. Published hours run from Monday to Friday office hours (Posso, and Square's free plan) to 24/7 support (Chefzi, Eatzy, Fudli, and Square on Premium).
• Chefzi's documented reliability features: a kitchen app that rings until an order is accepted or rejected; an SMS and an automatic call to your mobile or phone line if an order arrives while the device is offline; 24/7 support and a UK landline (020 3411 8110); and ordering that stays open until you pause it.

An ordering system that doesn't miss orders

An ordering system that doesn't miss orders keeps alerting until a person answers, tells you when the device is offline, and has a human you can reach. Here is what Chefzi documents for each, and nothing more:

• It rings until someone answers. The Chefzi Orders app rings until an order is accepted with a prep time or rejected with a reason.
• It tells you when the device is offline. If an order arrives while the device is offline, Chefzi texts the restaurant by SMS and automatically calls their mobile or phone line, so you know you are missing an order.
• You can reach a person. Chefzi support is available 24/7, and there is a UK landline: 020 3411 8110.
• It runs on a device you already own, with ordering staying open until you pause it in the dashboard.

Chefzi is £12 a month (£9 billed annually) on Starter, per location, ex VAT, with the first month free and no credit card. These alerts are on every plan. We publish no uptime percentage, and neither does any other provider we read, so test it yourself with the checklist below.

What each provider publishes

Providers are listed alphabetically. This is not a ranking. "Not stated" means we did not find it on the pages we read, not that it does not exist.

Flipdish, Grub Direct and Hungrrr show customer testimonials that mention reliability. Those are customers' opinions, not measurements, and we have not counted them. We did not find an uptime figure or SLA on their pages we read.

What Chefzi documents

These are the reliability features Chefzi describes on its own pages, and nothing more:

• Rings until answered. The Chefzi Orders app, on Google Play for Android and included with every plan, rings until someone accepts an order with a prep time or rejects it with a reason the customer can see.
• A text and a call if an order arrives while the device is offline. Chefzi texts the restaurant and automatically calls their mobile or phone line, so they know they are missing an order. Ordering stays open until you pause it, so a quiet tablet is not a closed shop; pause ordering in the dashboard if you need to stop orders.
• Orders on one device you already own. Orders arrive on a phone or tablet you already have. Chefzi does not sell hardware, so keep a charged spare, and read our kitchen tablet guide.
• Separate collection and delivery hours, so you can stop delivery at a busy time and keep collection open.

Like every provider in the table, Chefzi does not publish an uptime percentage or an SLA. Read the terms of any provider before you sign up, and compare the liability clause in each.

How to test reliability yourself

1. Ask for the commitment in writing. An uptime percentage, how it is measured, and what you get if it is missed. If the answer is "we don't publish that", you now know.
2. Pull the internet on your kitchen device during a test order. See what the system does, what the screen says, and how you would find out in a real service.
3. Check that unanswered orders cannot be missed. Does it ring until accepted, or send one notification?
4. Check how a human reaches you. Hours, channel and a named route for urgent problems, such as a Friday evening.
5. Place real test orders at your busiest hour. Not a quiet Tuesday, and not the provider's demo.
6. Keep a manual fallback. A phone number on your ordering page, a printed menu, and a rule for when to pause online orders.
7. Check who handles card payments and what you do if the card service is down but the ordering page is up.

When a different setup may suit you better

• If your top priority is a till that works with no internet, Posso and Gofood describe offline-capable tills. Chefzi's kitchen app needs a connection to receive online orders.
• If you need a contracted SLA, Storekit lists one on its Enterprise plan.
