Orders fail halfway when another system is down. How do I actually fix this?

This is one of the more expensive, invisible failures a small business website can have. A customer places an order, your site tries to log it in your CRM or notify your shipping system, that other system is briefly slow or down, the call fails, and because nothing retries it, the order just... doesn't fully register anywhere. The customer thinks they ordered. You don't know they did. Nobody finds out until the customer asks where their order is.

Why this actually happens

Most websites are built to call other systems synchronously, meaning the order process waits right there, in that moment, for the other system to respond before continuing. That works fine when every system responds instantly and reliably, which is most of the time, but not all of the time. Payment processors, shipping APIs, CRMs and other third-party services all have occasional slow responses or brief outages, and a website built without any retry logic treats that brief hiccup as a permanent failure, often silently, with no alert to you and sometimes no clear error to the customer either.

The fix most small businesses actually need: a no-code automation tool with retries

If your order flow already runs through an automation tool like Zapier or Make, connecting your store or form to your CRM, email, or shipping system, check whether error handling and automatic retries are turned on for that specific step. Both platforms support this, and it's often not the default; you may need to explicitly add a retry step or turn on a built-in retry policy for a given automation. This covers the overwhelming majority of small business setups, where the "other system" is a well-known CRM or shipping tool with an existing Zapier or Make connector, and no custom code is involved at all.

The custom-build fix: background jobs that retry automatically

If your order flow is part of a custom-built website rather than a no-code automation chain, the proper fix is a background job system designed specifically for this: the job runs after the order is placed, independently of the customer's checkout experience, and retries automatically if the system it's calling doesn't respond the first time. Netlify's version of this is called Async Workloads, built for exactly this kind of job: something that can wait, retry, and eventually succeed, like notifying a shipping system, or a delayed follow-up such as a reminder email sent days after an order, rather than something that has to happen instantly while the customer is still on the page.

The key design difference from the broken version of this flow: the customer's checkout doesn't wait on the other system at all. They see their order confirmed immediately, and the notification to your CRM or shipping system happens in the background, with retries, completely separate from what the customer experiences. If the other system is down for ten minutes, the background job simply retries until it succeeds, rather than the whole order failing the instant that system has a bad moment.

According to Netlify's own documentation, this is available on any site and plan level, billed like other provisioned resources on your account rather than as a separate add-on. I'd confirm the exact current limits directly with Netlify before committing a high-volume order flow to it, since the specific throughput ceiling for your plan isn't something I could independently verify on a reachable page, but the underlying model, a job that runs separately and retries, is the right shape for this problem regardless of the exact numbers.

A worked example

Say your online store notifies your shipping provider's API the moment an order is placed, and that API has a thirty-second outage during a busy sale. Under a synchronous setup, every order placed during those thirty seconds either fails outright or the customer sees a slow, possibly timed-out checkout, and you don't find out until shipping complains they never received those orders. Under a background-job setup, the order itself completes instantly and independently, the shipping notification job queues up, and when the shipping API comes back online a few seconds or minutes later, every queued job retries and succeeds without anyone needing to notice the outage happened at all, let alone manually resend anything.

When to skip building this yourself

A no-code automation tool covers most small business flows without any developer involvement at all, and that's genuinely the right call for most people reading this: check your Zapier or Make setup for retry handling before assuming you need custom code. A background job system like Async Workloads is for a genuinely custom application, not a standard e-commerce or form-to-CRM flow that an automation tool already handles well.

A practical note on finding out this already happened to you

Before assuming your current setup is fine, check whether you'd actually know if it wasn't. Look at whatever logs your payment processor, shipping tool or CRM keeps on their side, specifically for failed or rejected calls from your site around any day you know had unusual traffic or a known outage elsewhere. A surprising number of businesses find at least one quiet gap this way, orders that technically went through on the storefront side but never successfully reached the system that was supposed to act on them next, sitting unnoticed until someone finally went looking.

A practical note on alerting yourself while you wait for a proper fix

If a proper background-job fix isn't happening this week, a cheap interim step is worth doing immediately: add a simple alert, even a basic email notification, whenever a call to the other system fails, so you at least know it happened in near-real-time rather than finding out days later from a confused customer. This doesn't fix the underlying reliability problem, the order still fails the first time, but it closes the much worse gap of nobody knowing at all, buying you time to manually recover the specific order while you work on the real fix.

What I'd actually tell you

If you've had even one order silently disappear this way, it's worth the half-day of setup to fix properly, because the actual cost isn't the occasional outage, it's the customer who never got their order and the trust that costs you when they find out the hard way. Most of the time this is a cheap fix: either a retry setting you turn on in a tool you already use, or, for a genuinely custom build, a background job that someone needs to design once and then never think about again.

How I'd approach this

When I build an order or lead-capture flow for a client, I design the critical path (the part the customer actually sees and waits for) to be as short and reliable as possible, and push everything that can tolerate a short delay, notifications, CRM syncs, follow-up emails, into a background job that retries on its own. That one architectural decision is usually the difference between "an outage somewhere else briefly inconveniences us" and "an outage somewhere else loses us a real order," and it's worth getting right from the start rather than retrofitting after the first customer complaint.
