Most Shopify stores are leaving revenue on the table
If your growth depends only on traffic, you are capping your revenue. More visitors help, but they are not the only driver of revenue.
Top-performing stores focus on what happens after the click. They improve how visitors buy, not just how many visitors arrive. That means getting more value from each order, recovering visitors who would have left, and increasing repeat purchases.
In this Profit Pumper article, we’ll review the best Shopify apps to increase sales across these key areas and how each one helps turn existing traffic into higher revenue.
But first…

What “Shopify Apps That Increase Sales” Actually Do
They are apps that improve how a store earns revenue from existing traffic.
Some focus on a single part of the journey, while others influence multiple stages of the buying process. From the moment a customer lands on your store to the moment they leave, each app targets a specific revenue lever.
Most high-performing stores rely on four core functions:
1. Upselling & bundling (Increase AOV)
These tools increase how much customers spend per order. They work by suggesting product bundles, quantity breaks, or add-ons that feel natural during the buying decision.
2. Conversion Tools (Reduce Drop-offs)
These apps help more visitors complete their purchase. They remove friction using popups, live chat, personalization, or on-page optimizations that support decision-making.
3. Recovery Tools (Bring Back Lost Visitors)
Not every visitor buys on the first visit. Recovery tools bring them back through email, SMS, and targeted reminders, helping capture revenue that would otherwise be lost.
4. Retention Tools (Increase Repeat Revenue)
These apps focus on customers after purchase. Loyalty programs, referrals, and rewards systems encourage repeat buying and increase lifetime value.
