My Shopify store suddenly stopped selling: what should I check first?

Yesterday you sold. Today, you didn't. You check your Shopify dashboard and orders have stopped dead. There's no error notification, no alert message — just silence where there used to be activity. It's one of the most distressing situations a store owner in LATAM can experience, and unfortunately, it's more common than it seems.

When a Shopify store suddenly stops selling, the cause is almost never obvious. It could be a silent technical error, an app that updated itself and broke something, a payment gateway that stopped working, or simply a drop in traffic unrelated to the store itself. The problem is knowing where to start.

In this article, I'll give you a concrete guide on what to check first, in what order, and how to identify if you can solve the problem yourself or if you need urgent technical help.

The first thing to rule out before panicking

Before checking anything technical, there's a question you must answer: did you really stop selling, or did you just stop receiving notifications?

It sounds obvious, but it happens frequently. Order notifications can fail due to email configurations, spam filters, or changes in the email address associated with the account. Go directly to your Shopify dashboard, navigate to Orders, and check for recent activity. If there are orders there even if you didn't receive notifications, the problem is with email, not sales.

If the dashboard confirms that there are indeed no orders, the next step is to make a real test purchase. Go to your store from an incognito browser, add a product to the cart, and try to reach the checkout. You don't need to complete the payment — just verify that the process isn't interrupted before reaching the payment screen.

If the purchase process works smoothly, the problem is likely not technical — it's traffic-related. If the process is interrupted or shows an error, you've found where to start.

Check the checkout: the most frequent culprit

The checkout is the most sensitive point of any Shopify store and the place where problems that halt sales most frequently appear. A single broken line of code, a conflict between apps, or an unauthorized change in settings can cause your customers to reach that point and leave without buying.

The first thing to check is if the payment button responds. Go to the checkout in incognito mode from your cell phone, fill in the shipping details, and verify that you can reach the payment method selection screen. If the process freezes or an error appears at any point, you have identified where the problem lies.

The second thing is to check if your theme has custom scripts in the checkout. If at some point someone added JavaScript code to the checkout for tracking, discounts, or any other function, a Shopify update may have invalidated it without notice. This is especially common in stores that migrated to Shopify from another platform and carried over old customizations.

The third thing is to verify that your payment methods are active. Go to Settings → Payments and confirm that all methods appear as enabled. Sometimes a failed account verification or a change in associated bank details can deactivate a payment method without you knowing.

Payment gateway issues in LATAM

Local payment gateways are one of the most frequent points of failure in Shopify stores in Mexico, Colombia, and Argentina. MercadoPago, Conekta, PayU, and other regional solutions have their own APIs, their own update cycles, and their own configuration requirements — and any change on their side can break the integration with your store without Shopify notifying you.

The first step is to go directly to the gateway's panel — not Shopify's — and verify that your account is active, that there are no pending verification alerts, and that the integration credentials (API keys, tokens) are still valid. MercadoPago and Conekta credentials have expiration dates that many store owners are unaware of.

The second step is to make a test transaction with the minimum allowed amount. Some gateways have sandbox environments for this. If not, use a low-priced product and complete the real purchase to confirm that the payment flow works end-to-end.

If the gateway is active and the credentials are valid but the payment still fails, the problem may be with the plugin or app that connects Shopify with the gateway. Check if there has been a recent update to that app and if there are reports from other users with the same problem in the Shopify App Store.

When the problem isn't technical but traffic-related

If you did the test purchase and everything works, the problem isn't with the store — it's with who is reaching it. Or more accurately, that no one is reaching it.

Open Shopify Analytics and check the sessions for the last 7 days compared to the previous week. If there's a significant drop in visits that coincides with when you stopped selling, the problem is traffic-related.

The most common causes of a sudden drop in traffic to LATAM stores are three. The first is the exhaustion of a paid campaign budget — if you rely on Meta Ads or Google Ads and a campaign was paused or ran out of budget, visits can plummet overnight. The second is a Google penalty for duplicate content, extreme speed, or a technical indexing problem. The third is seasonal — there are weeks of the year when certain markets simply buy less.

If traffic dropped, first check your active campaigns. Then check Google Search Console for coverage errors or recent penalties. And finally, compare with the same period last year to rule out seasonality.

Apps that updated and broke something without warning

This is one of the most frustrating problems because it's completely invisible. Shopify apps update automatically in the background. You don't receive any notifications, you don't approve any changes — one day something just stops working and you don't know why.

To identify if an app is causing the problem, there's a simple technique: temporarily disable the apps you installed most recently or those that updated in the days leading up to the sales drop. You can see your store's activity history in Settings → Activity log. If disabling an app makes the problem disappear, you've found the culprit.

The apps most frequently in conflict are those that modify the checkout, those that inject scripts into the theme, upsell and cross-sell apps, and translation or multi-currency apps. Not because they are bad apps, but because they operate in sensitive areas of the store where a small change has big consequences.

What each hour costs you without resolving the issue

When a Shopify store stops selling, the clock is ticking against you. Not metaphorically — but literally and quantifiably.

Imagine a store in Colombia that sells an average of 20 orders daily with a ticket of 150,000 Colombian pesos. That's approximately 3,000,000 pesos per day, or 125,000 pesos per hour. Every hour that the store has an unresolved technical problem is money that doesn't come in. And that money isn't recovered — customers who arrived during the failure and couldn't buy won't automatically return.

To that, you must add the cost of paid traffic that continues to run while the store isn't converting. If you have active campaigns on Meta or Google, that budget is being spent to drive people to a store that can't sell them anything.

This is the most honest argument for active maintenance: it's not about paying for something you "might" need. It's about having someone available for when the clock starts ticking, because it will. The question isn't whether it will happen — it's how much you'll lose when it does and how long it will take you to resolve it.

What to do if you've checked everything and it's still not selling

If you've made it this far, checked the checkout, payment gateways, traffic, and apps, and your Shopify store is still not selling — the problem is probably in a deeper layer that requires technical eyes with direct access to the code and configuration.

There are errors that are not visible on the surface. Conflicts between the theme and an app that only manifest in certain browsers or devices. Caching problems that cause some users to see an outdated version of the store. Errors in webhooks that process payments. Third-party scripts that block checkout loading on slow connections.

None of these are resolved with YouTube tutorials or general Shopify support. They require someone who can open the browser console, read error logs, review the theme code, and test in different environments until the root of the problem is found.

At YoSoyShopify, we do this type of diagnosis from day one when you activate the hours. No waiting, no budgets to approve, no intermediaries. If your store already generates sales and you can't afford to continue without active technical support, the next step is simple.

Maintaining your Shopify store is not an optional expense — it's what protects the income you've already built. And when something fails, the difference between resolving it in hours or days can be directly measured in lost sales.
