Flash sales

Flash salescan provide great opportunities to sell a large quantity of products in a short period of time, but they can require some preparation if you're expecting a large increase in your checkouts. In most cases, special preparations are recommended only if you're running a flash sale and you expect tens of thousands of customers to start a checkout within a few minutes.

For example, Shadi usually gets 10,000 visitors and 100 orders per day. They're running a flash sale and expect 50,000 visitors and 1000 orders over a period of 24 hours. This sale doesn't require any special preparation. Later, Shadi's business is featured on a major network, and they set up a flash sale to take advantage of the feature. They expect a significant increase in demand, with tens of thousands of customers competing for inventory, with stock selling out in minutes each time it's restocked. That's a substantial increase, and requires some preparation to make sure the flash sale goes smoothly.

Plan in advance

If you determine that your flash sale will generate enough orders that you need to prepare in advance, then you should start as soon as possible. When appropriate, start your preparations weeks in advance to make sure you have time.

Prepare preview products

If you want to provide a preview of the products you're offering during your flash sale, then create unique preview products separate from the ones that you'll actually be offering for sale when the event begins. When you publish products to your online store with inventory available, customers are able to complete a checkout with those products. While some theme modifications can hideAdd to cartactions, these shouldn't be relied on to stop customers from purchasing.

Review product information for international sales

If you sell internationally andcollect duty and import taxes, then consider disabling the collection of duty and import taxes until your sale is complete. If you decide to collect duty and import taxes during your sale, then review your sale products to verify that they have the following information:

确保你有这些字段填写your sale products helps to estimate duties and import tax costs. If your product does not have an HS code or a product type, duties and import tax will not be calculated for that product.

Create a branded password page

In the event that a technical issue with a third party affects your ability to serve your customers, the best course of action is to lock your storefront to prevent the issue from getting any worse. If you activate your password page, then new visitors are unable to create a new checkout in your store, but customers already in the process of checking out can complete their purchases. Locking your storefront lets you to make changes and resolve the issue in the background, and assure users that you're working to resolve the issue and resume your sale.

Create a theme with event-specific collections and product pages

Create a collection specifically for your sale items and, if possible, a theme that highlights and simplifies your product pages. Showing streamlined collections and product pages during the sale provides an easier, faster checkout experience for your customers. In particular, consider disabling the following:

Collection filtering menus
Recommended products
Social network feeds
Slideshow or carousel views
Popups or upsell functions

Deactivating fulfillment locations

If you have more than one fulfilment location active,then deactivate all locations,except for the one that inventory is assigned to for the sale. When you have more than one active inventory location during a flash sale, it can cause your online store to respond slowly, or create errors that prevent your customers from completing checkout.

Capture payments manually

If you capture payments automatically, then you should consider changing your settings tocapture payments manuallyfor the duration of your flash sale. Capturing payments manually avoids potentially high credit card fees in the event of overselling or cancelled orders, and allows you to review and verify that orders are legitimate before the payment is completed and the fulfillment process starts.

There are two versions ofcustomer accounts: classic and new customer accounts. In classic customer accounts, customers can log in using an email and a password. In new customer accounts, customers can log in using a one-time six-digit verification code that's sent to their email address. When you run a flash sale, your store can use the classic customer accounts login method, but you can't use the new customer accounts login method. You can hide thenew customer accountslogin during a flash sale. Shopify will still associate orders with customers during checkout even if the customer isn't logged in to their customer account.

Review third-party functions

For large flash sales, you need to make sure that your third-party integrations can handle the increase in traffic to your store.

Apps

If you have third-party apps as part of your checkout process, then you should contact the developers with an estimate of the volume of orders you expect and the duration of your sale. They can provide information on what their app can handle. If they're not confident that the app can support the amount of checkouts that you expect, then consider disabling the app for the duration of your sale.

Shipping apps

Shipping apps typically display poor performance during extremely high volume events. Because a checkout can't be completed if shipping rates aren't provided, consider disabling shipping apps and carrier-calculated rates for the duration of your sale. Instead,set up custom flat ratesdirectly in your Shopify admin. For example, if you have a shipping app installed in your Shopify admin that provides calculated shipping rates to your customers, then you should consider disabling the app, and use your own custom flat rates instead. Using your own custom flat rates lets your customers complete the checkout without needing to wait for shipping rates to be calculated.

Custom apps

If you havecustom appsinstalled in your store, then you should review them to make sure that they are as efficient as possible and that the API call rate is sufficient. If you aren't sure that an app can handle the volume you're expecting, then consider disabling it for the duration of your event. Refer to our guide on你使用Shopify最大化PIto learn more.

Payment providers

If you don't useShopify Payments, then contact your payment provider to ensure they can support the volume of sales you expect. Consider setting up a second payment provider in case your primary provider isn't able to keep pace with your orders. Make sure to test your providers beforehand to ensure there aren't any problems for your customers at checkout.

External payment providers

An external payment provider is a service that directs customers to complete their payment outside of Shopify, and includes payment options that allow paying later or partial payments. These payment options can result in overselling of merchandise, because of the time needed to transmit the checkout to a third-party service and back again with completed payment information. If you offer a payment option like this, then consider disabling it for the duration of your sale.
