How to handle Shopify incidents, outages, and errors (6 step framework)

Checkout failures during a flash sale. A theme update that breaks mobile payments. A Shopify outage on Cyber Monday. These incidents happen, and they can cost you thousands or millions in lost revenue if your team doesn't have a clear response process.

In this article, you will learn a practical, 6-step incident response process for the most common Shopify incidents, errors, and outages that hurt your revenue.

We will help you and your team define roles, triage steps, and severity levels, and provide a ready-made comms template for use whenever accidents occur.

The most common Shopify incidents you will face

When we talk about an ‘accident’, we refer to both outages beyond your control, whether full as the latest Cloudflare blackout, or partial platform degradation affecting different Shopify functions (Checkout, admin, etc.), and daily issues or changes you introduced that are within your control.

You have likely encountered or might be subject in the future to the following:

Theme and front-end deployment incidents (change-related)

• Bad theme release (Liquid/templates/assets broken)
• JavaScript conflicts
• Performance regression (site becomes slow after a change)

Apps, extensions, and automation incidents

• App outage or degraded performance
• Checkout extensibility/UI extension issues
• Webhooks failing (downstream desync)

Integrations and back-office incidents (order-to-fulfillment risk)

• ERP/OMS/WMS sync failures
• Fulfillment and shipping provider issues (3PL/ShipStation/labels)

We teamed up recently with our partner Patchwork to outline what merchants typically get wrong about ERP integration. Peak trading, crashing, and system failures were among the leading causes of team distress.

Tracking and attribution incidents (decision-impacting)

• GA4 purchase/refund tracking is broken
• Pixels failing/Tag Manager misfires

It's very common for merchants to encounter errors when setting up purchase and refund event tracking in GA4. It's important to follow the procedure step by step, with the right data layer we have provided in our guide.

Storefront and checkout incidents (revenue-impacting)

• Checkout not loading / checkout errors
• Payments failing
• Add to cart not working
• Storefront not loading / 5xx spikes

Incidents are only part of the reason customers fail to convert. Discover the 7 major Shopify Checkout Mistakes.

Admin and platform-level incidents

• Shopify platform incidents (checkout/API disruptions)
• CDN/DNS/edge outages

Security and compliance incidents

• Compromised staff account/suspicious admin activity
• Fraud spikes

You need a system to handle Shopify Incidents and outages

All the accidents listed above demand a different solution, and they’re just a few of what you can encounter. Our goal is to help you avoid any accident - the only way to do so is to define a system that doesn’t break in high-pressure situations.

Why a system?
It’s not uncommon for two or more incidents to occur at the same time; team members may not be present when they happen, while daily operations need to continue. There’s no option but to follow a strict operating model, similar to the one we apply for our own customers.

An outage on your busiest day, as on Cyber Monday in 2025, when a login/authentication flow issue affected merchant access to Admin, can significantly reduce your revenue. Any minute saved could mean millions, or at the worst, survival that year.

Defining roles in an incident

Ownership must be explicit, and roles must be defined when handling an accident. This is the most important part of any incident response plan.

Incident lead
The incident lead is the coordinator and decision maker. The role is to keep everyone aligned and call the shots when needed.

The incident lead has the following responsibilities:

• Declares the incident and assigns severity
• Sets the immediate objective (restore checkout, stabilize storefront, stop further damage)
• Assigns owners for triage, fix, comms, and documentation.
• Controls change: approves rollbacks/hotfixes and prevents random deployments
• Keeps a tight cadence and updates the team continuously

Technical lead
The Tech Lead owns diagnosis and resolution. This could be a single person or a group with a dedicated manager, similar to how we approach developing a Shopify store.

• Reproduces the issue and identifies scope (which pages, devices, markets, payment methods)
• Isolates the cause (theme change, app conflict, Shopify outage, integration failure)
• Implements the fix (rollback theme, disable app, revert GTM publish, adjust settings)
• Validates recovery (checkout test orders, add-to-cart, shipping rates, tracking events)
• Reports status to the Incident Lead (“cause likely X; ETA unknown; next action Y”)

So far, with these two roles, we have identified the issue and sorted it. But what happens with customers in the meantime if your page breaks?

Communications Lead
The Communication Lead is key to ensuring alignment among customers, customer support, and internal stakeholders. Without this role, you risk losing revenue and facing waves of negative reviews and support emails from frustrated customers.

The Comms Leads own the following:

• Coordinates with Support/CS to ensure consistent responses and macros
• Drafts and publishes updates (internal Slack/Teams, customer banner/email/status page)
• Communicates scope, impact, and workarounds (what customers should do right now)
• Avoids speculation; confirms what’s known and what’s being investigated
• Notifies everyone when fixes are applied in the most effective way possible

All is now complete, except for one final element that’s key to handling the accident faster in the future.

Scribe
This role owns the documentation of accidents and fixes. They might or might not be separate from the other role, depending on the size of your team, but they can’t be absent unless you want to go through the same long process if the same accident repeats

• Keeps a timestamped incident log: symptoms, decisions, actions, outcomes
• Captures links and evidence (Shopify Status, error screenshots, release notes, commit hashes, GTM versions)
• Records what worked, what didn’t, and action items
• Produces the post-mortem draft (or facilitates it) within 24–72 hours

Handling Shopify issues and outages with a small team

Everything revolves around these four roles, which follow the same steps, regardless of the nature of the accident. Now, to the question you might have: how to manage these four roles when you have fewer or more people?

For a small team of 1-3 people

• Blend the incident lead and the communication lead, considering that the role requires a high level of knowledge of the accident and effective communication with all team members.
  
• Blend the tech lead with the scribe, considering the tech-savvy nature of documentation

For a large team, more roles can be added in a ‘war room’ fashion. A deputy lead should be appointed if the head lead is absent, and tech leads should be assigned based on their areas of expertise.

A good example is how we at Shero. With a large team, the various incident leads know exactly which developer is best suited to handle the issue and take ownership.

You can delegate incident response
Scaling often comes with more complex incidents. Longer offline times lead to much larger losses, so a solution is to delegate incident response to an external support team that already has the system in place.

For our clients, we handle the incident lead, dedicated tech lead, and scribe. We maintain open communication with the company throughout the process so that the company's Comms lead or the person in charge is aware of what to share with the audience.

With this Hybrid model:

• The internal team (company) owns Incident Lead, Comms, and approvals.
  The external partner owns Technical triage + Implementation under change control, plus monitoring and postmortem drafting support. The Incident lead can also be on the partner side, depending on the issues.

What would take hours generally takes minutes to solve using this system. To catch incidents on time, we also created our channels of communication that are specifically built for Shopify Plus and B2B - our Tech lead team can give you an idea of how it works and how it compares with DIY methods

The 6-step Shopify incident response framework (with examples)

Our Shopify incident response process involves six steps that loop around. To make it more practical, we will go through all based on two scenarios:

• Shopify checkout outage
• Checkout is broken due to a change on your site

1. Detection and confirmation

Assignee: Incident lead
Participants: Incident lead + Comms lead

The first phase is to determine whether there is an accident at all and not a one-off situation, and to assess its severity level

Severity levels are not assigned based on problem complexity, but on business impact.

• SEV1 – Critical: Revenue is blocked (checkout, payments, or storefront down).
  SEV2 – Major: Revenue is degraded (partial checkout failure, payment method down, region/device affected).
• SEV3 – Minor: No immediate revenue impact, but functionality or data is impaired(tracking, admin, non-critical flows).
• SEV4 – Low: Cosmetic or edge-case issue with negligible business impact.

Let’s consider the scenario where multiple customers can’t complete checkout. The first thing noticed is a sudden drop in revenue during the first hours of the day, with a few customer messages (the few who don’t simply leave for another store) saying they can’t complete checkout.

Scenario one: Shopify checkout outage

• The Incident Lead confirms there are multiple reports of the incident and assigns SEV1 - the highest severity level to this incident.
• All deployments on the website are frozen
• The issue is handed over to the Tech Lead to reproduce the problem and determine the cause.
• The Comms Lead is on hold; they are not acting yet, but are prepared to notify stakeholders immediately and support the incident Lead’s command.

Scenario two: a theme update broke checkout on mobile

In this phase, we assume the Incident Lead has no information about the nature of the error. The only information is the repeated reporting of checkout failure; thus, the same steps will be applied.

Exception: When Shopify has an outage, it quickly becomes news. Within minutes, the Incident Lead can perform a simple test and coordinate immediately with the Comms Lead to notify all parties involved.

2. Triage

Assignee: Technical Lead
Participants: Technical Lead, Incident Lead

The goal of the Triage phase is to pinpoint where the failure occurs and, if possible, isolate it to minimize the impact on revenue.

The Tech Lead received a notification from the Incident Lead that there are multiple reports of failed checkout.

Scenario one: Shopify checkout outage

• The first thing (unless it’s already news) is for the Tech Lead to reproduce the error across multiple devices and screens. During an outage, none will work unless it’s a partial outage affecting only one platform.
• The Tech Lead will check the Shopify store's status. In this scenario, it will report the problem to the Incident Lead.
• The Incident Leads notify the Comms Lead, who notifies all customers via a banner on the website, and customer support of the problem and what to report to customers.

Speed is essential: There is an art in communicating outages and website failures to customers. Thus, the Comms Lead's role should be tightly controlled yet have sufficient authority to deliver a message on time without micromanagement.

Scenario two: a theme update broke checkout on mobile

• Same as the original scenario. The Tech Lead receives the message from the incident lead and reproduces the error in multiple devices. Checkout errors only on mobile are noticed
• Shopify status is green
  
• The Tech Lead notifies the incident Lead of the error and its connection to the possible recent theme update.

The conclusion: the issue is internal and change-related.

3. Mitigation

Assignee: Technical Lead
Participants: Technical Lead, Incident Lead, Comms Lead

The mitigation phase is where the work of fixing the problem or minimizing its impact is done.

Mitigation is often about quick action, such as rolling back the theme, disabling app embed, reverting the pixel, and stopping ads. Remediation might or might not be possible; even when it is, it’s typically followed up after the incident report loop is closed.

Scenario one: Shopify checkout outage

The Tech Lead can’t fix a Shopify outage. Thus, mitigation is the only way.

• Paid campaigns driving to checkout are paused.
• The Comms Lead is notified to set up a storefront banner or status message, and the Tech Lead approves (in some cases, the Incident Lead). In busy periods, social media messaging also helps.
• The Comms Lead is notified of the technical specifics to share with customers.

Scenario two: a theme update broke checkout on mobile

• The Tech Lead rolls back the theme update.
• The Tech Lead tests if the issue is fixed, and only then messages the Incident Lead.

4. Validation

Assignee: Technical Lead
Participants: Technical Lead, Incident Lead

The validation phase ensures that the issue is resolved. For a small problem, it might already be validated in the Mitigation phase; however, there is a difference. Validation goes a level deeper, through the whole customer journey, and might find new issues the fix introduced.

We recommend that the Comms Lead notify stakeholders and customers that the issue is resolved only after it has been validated by both the Incident Lead and the Tech Lead.

Scenario one: Shopify checkout outage

• Shopify status is first checked
• Tech Lead tests whether the full checkout flow is tested, payments succeed, and the confirmation page loads.
• The Incident Lead is informed that “Checkout and payments are validated successfully.”

Scenario two: a theme update broke checkout on mobile

The same steps are followed, whether it’s an outage or not. Now it’s up to the Incident Lead to instruct the Comms Leads whether to share an update or wait until monitoring is complete.

5. Monitoring

Assignee: Incident Lead
Participants: Incident Lead, Technical Lead, Scribe

The next step is to monitor whether the issues recur. The Incident Lead determines the monitoring window based on severity and traffic patterns.

How long to monitor?

• SEV1 incidents: Monitor for at least 2 hours after validation, extending to 24 hours during peak traffic
• SEV2 incidents: 60-90 minutes of active monitoring
• SEV3/SEV4 incidents: 30 minutes or until the next traffic pattern shift
• High-traffic periods (Black Friday, flash sales): Extend to 24-48 hours with rotating coverage

What to monitor exactly and how?

The table below outlines what to monitor and what tools to use.

Now it's time to take the final call.

Escalate and reopen the incident if:

• Any monitored metric degrades by >10% from baseline after 20+ minutes
• New error patterns emerge that weren't present during initial triage
• Customer support reports a different symptom related to the same area
• The issue recurs intermittently

Close the incident when:

• All four metric categories show stable baseline performance for the full monitoring window
• No new reports from customers or support
• Tech Lead confirms system logs are clean
• Scribe has captured all data for the postmortem
