Does Advanced get the same 99.99% uptime positioning and priority support as Plus, or is that support-tier difference real?

What uptime does Shopify promise on every plan?

Shopify's Terms of Service promise no uptime on any plan. They provide the Services on an “as is” and “as available” basis “without any warranty or condition, express, implied or statutory” (Shopify Terms of Service, October 2026). They add that Shopify “does not warrant that the Services will be uninterrupted, timely, secure, or error-free.”

That is the baseline for Basic, Grow and Advanced. There is no published uptime commitment on any of them, not even a weaker one. The Terms carry no plan-specific uptime clause, so that floor sits under any Advanced vs. Plus decision at $1M a month.

Does Shopify Plus come with a 99.99% uptime service level agreement?

Shopify Plus might come with a 99.99% uptime service level agreement (SLA), but Shopify does not state it as an inclusion. The Help Center's Plus plan page says the plan “might also include a 99.99% uptime SLA (service level agreement)” (Shopify Help Center, October 2026).

We did not find published SLA remedy terms. Nothing says what a breach entitles a Plus merchant to, how the SLA measures uptime, what it excludes, or whether service credits exist. Shopify does not publish them with the plan description, so we will not describe remedies we have not read. If uptime is load-bearing for your business, ask for the SLA by name before you sign a Plus term:

1. How is uptime measured?
2. What is excluded? Shopify's own platform uptime figure leaves out third-party outages, errors from theme customization or apps, planned maintenance, and major or natural events outside Shopify's control (Shopify Help Center, October 2026).
3. What is the remedy?

Is the 99.99% on Shopify's Plus pages a commitment?

No: the 99.99% on Shopify's Plus page is an observed platform average, not a commitment to any store. The page shows “99.99% uptime” “on average across Shopify worldwide during the biggest flash sales and events of the year” (shopify.com/plus, October 2026). Because the average covers all of Shopify, Advanced stores sit inside it too.

An average describes how the platform behaved. A service level agreement (SLA) describes what Shopify agrees to, so the same digits make two different claims. We often hear the average quoted back as though it were the contract, and it is not. Because Advanced stores share the average, upgrading for uptime reassurance buys priority support and, at most, an SLA, not a better platform average.

How does Plus support differ from Advanced support?

Plus support differs from Advanced support in priority, channel and what it can switch on, not in any published response time.

Shopify Plus Support is also how some Plus features get turned on, so it is more than a faster queue. Bot protection needs a request to Shopify Plus Support (Shopify Help Center, October 2026). The Plus plan page adds that you “can request increased API rate limits by contacting support” (Shopify Help Center, October 2026).

When should uptime and support stay out of the Plus decision?

Uptime and support should stay out of the Plus decision when your incidents are your own, when nobody can use an escalation path, or when the 99.99% comes without a source.
