When running an online store, one effective technique for significantly boosting sales in a short period is the "flash sale." A flash sale is a promotional strategy that runs for a very short, limited period—anywhere from a few hours to a day—offering a much larger discount than usual.
This article provides a practical explanation of how anyone can easily start a flash sale using Shopify's standard features.
What Is a Flash Sale?
A flash sale is a limited-time discount offer that runs for a very short period (typically anywhere from a few hours to a day). As the name "flash" suggests, this type of sale has a "momentary," "sudden" character.
Characteristics of a Flash Sale
- Extremely short sale period (a few hours to around 24 hours)
- Large discount rate (discounts of 50% or more are not uncommon)
- Limited quantity, ending as soon as stock runs out
- Little advance notice in many cases
- Stimulates purchasing motivation by creating a sense of urgency
Difference Between a Flash Sale and a Time-Limited Sale
A time-limited sale is a sale that runs for a set period with a time restriction. The main differences between a flash sale and a time-limited sale are as follows.
| Item | Flash Sale | Time-Limited Sale |
|---|---|---|
| Duration | A few hours to about a day | A few days to a few weeks |
| Notice | Sudden, announced right before it starts | Advance notice is common |
| Discount rate | Very high | Moderate to high |
| Frequency | Irregular, sudden | Often held on a regular basis |
| Number of products | Limited | Wide range of products, up to the entire catalog |
| Strategy | Creating a sense of urgency and scarcity | Planned promotion |

How to Run a Flash Sale on Shopify
Use Shopify's Native Discount Feature
By using Shopify's native discount feature, you can easily run a flash sale on specific products or specific collections.
The blog article below explains Shopify's native discount feature in detail. Please use it as a reference.
Use a Shopify App
If you want to run a flash sale limited to specific members, such as VIP members only, or want to run a tiered flash sale (e.g., 50% OFF for 1 item, 60% OFF for 3 items, 70% OFF for 10 items), Shopify's native discount feature will fall short. If you want to run a more complex flash sale, consider using a Shopify app.
