The short answer: Selleasy is an upsell and cross-sell app for Shopify that displays post-purchase, thank-you, cart, and product-page offers through a visual builder with no code. You can have a post-purchase upsell live in about 20 minutes, and that is the only offer you should build in your first hour. The other types each require theme and design decisions that cost time before they earn anything, so they belong in hour two. This guide walks the first hour in order: install from the App Store, connect your store, create one post-purchase offer, test it in a real checkout, and stop. Selleasy's free plan includes a monthly limit on the number of orders you can process, so the first hour costs you nothing in app fees.

If you are starting from zero, our how to start a Shopify store guide covers the full setup from signup to your first product. For a broader view, how Shopify works step by step walks the admin from settings to fulfillment.

Selleasy sits in a crowded category. Shopify's App Store lists dozens of upsell apps, and the question here is narrower than "which one?" It is what you actually click in the first 60 minutes. Not what the app can do eventually. What you build, what you skip, and when you stop.

What Selleasy does, and why most of it waits

Selleasy builds four kinds of offer. Post-purchase upsells appear on the page between checkout completion and the order confirmation. Cart offers appear in the cart drawer or cart page. Product-page offers show a widget on the item page. Thank-you offers render on the order-confirmation page itself.

Each type does a different job, and each costs a different amount of setup time. The post-purchase offer is fast because it renders inside Shopify's checkout. It does not touch your theme. The other three each require you to match the offer widget to your storefront's styling, which is where the clock goes.

E-commerce adoption keeps climbing. In 2024, 23.59% of EU enterprises reported e-sales, up from 18.93% a decade earlier, according to Eurostat. And up to 70% of SMEs intensified their use of digital technologies because of COVID-19, the OECD reported in 2021. Tools like Selleasy ride that wave. But only the first offer you build matters in hour one.

The post-purchase offer renders inside Shopify's checkout, so it works with no theme edits and no widget styling. That is why it is the one to build first. The free plan's order limit leaves room to learn whether upsells move your average order value before you pay a cent.

Why the post-purchase offer earns first

The Baymard Institute reports a global average cart abandonment rate of 70.19%. That number is the whole argument for post-purchase offers. The customer who reaches the post-purchase page has already paid. You are not trying to rescue a cart. You are offering one more item to someone who just proved they will buy.

Baymard also found that only 2% of benchmarked e-commerce sites have a "good" checkout flow, while 65% are "mediocre" or worse. Adding an offer before checkout risks adding friction to a flow that is already broken for most stores. Post-purchase offers add zero steps to the checkout path. The customer has finished. The offer is a yes-or-no on a single page.

The same research found that the average e-commerce site has 32 unique checkout improvements to make and can gain a 35% increase in conversion rate through better checkout UX. That is an argument for fixing checkout, not for stacking more offers in front of it. Get the post-purchase offer working first. Then decide whether the product page needs one.

Before you install: the five-minute checklist

Five things need to be in place before you install Selleasy, or the 20-minute setup will stall. Here is our suggested pre-installation checklist:

• At least two products published in your Shopify admin.
• Shopify Payments or another payment gateway active and processing test orders.
• Your checkout set to live mode, not password-protected, so the post-purchase page can render.
• A test product priced low enough to buy with a real card.
• A desktop browser open, since the Selleasy builder is not designed for mobile screens.

If you have not connected Shopify Payments yet, how much does Shopify cost walks through the plan and processing-fee structure. The processing rate you pay per order is separate from Selleasy's pricing.

The 20-minute setup: install, connect, create your offer

This is the one numbered list in the guide. Each step takes roughly the time listed.

1. Install Selleasy from the App Store (2 min). Open the Selleasy listing in Shopify's App Store and click "Add app."
2. Accept the permissions prompt (1 min). Selleasy needs access to your checkout, orders, and product data to render offers.
3. Confirm your store is connected (2 min). The Selleasy dashboard should show your store name and domain. If it does not, reconnect from the settings tab.
4. Click "Create offer" and select "Post-purchase" (3 min). Choose this type over cart, product page, or thank-you.
5. Set your trigger and offer product (5 min). Pick a product the customer must buy to trigger the offer, and a second product to show as the upsell. Set a discount if you want one, either a percentage or a fixed dollar amount.
6. Publish the offer (1 min). Toggle it live. The default template works in checkout without design edits.
7. Place a test order (6 min). Buy the trigger product with a real card at a low price. After checkout, the post-purchase page should show your upsell.

Test your offer without breaking anything

Testing a post-purchase offer means placing a real order. There is no preview mode that shows the post-purchase page without a checkout. Shopify does not render it outside a completed transaction.

Use a product priced at $1. Run a real card through Shopify Payments. The processing fee on a $1 order is negligible. After checkout completes, the post-purchase page should display your upsell with the product image, price, and "Add to order" button.

Mobile devices (excluding tablets) accounted for 51.48% of global website traffic in Q2 2026, down from 62.73% in Q2 2025, according to Statista. Test the offer on a phone, not just a laptop. The Nielsen Norman Group's mobile checkout research documents how often mobile-specific layout breaks — form fields, button sizing, scroll behavior. If the upsell page looks broken on a phone, most of your customers will never see it.

After confirming the offer appears, refund the test order from your Shopify admin. The upsell product will not be in the order unless you clicked "Add to order" during the test. If you did, refund that line item too.

Skip these in hour one

Features that look urgent but belong in hour two or later.

• Bundle offers. Bundles require you to choose which products group together, set a bundle price, and decide whether the discount applies per item or per set. That is a pricing decision, not a setup task.
• A/B tests. Split testing needs traffic you do not have yet. Running a test on 20 orders tells you nothing statistically meaningful.
• Custom CSS. Selleasy's builder has a CSS tab for styling overrides. The default template works. Custom CSS on your first offer is time spent on aesthetics, not revenue.
• Cart and product-page widgets. These require matching the widget to your theme: fonts, colors, button radius, spacing. That is 30 to 60 minutes of design work before the first customer sees anything.
• Funnel logic. Selleasy supports rules like "show offer A to customers who bought product X, and offer B to customers who bought product Y." That is a second-hour feature. One offer, one trigger, in hour one.
• AI-powered recommendations. Selleasy offers AI-driven product recommendations for automated cross-sell pairings. Those belong after you have proven that manual pairings convert. Let the data from your initial orders inform the AI, not the other way around.

Your free plan covers this setup

Selleasy's free plan covers up to 50 orders per month, according to its App Store listing checked August 30, 2026. Prices can change, and the App Store listing is the authoritative source. The free plan includes all offer types, not just post-purchase. Paid tiers scale by monthly order volume, so the upgrade decision should follow your order count, not your ambition.

The practical read: if your store does fewer than 50 orders a month, the free plan covers everything. If you do more than 50, the paid plan's cost should be less than the extra revenue one working upsell generates. If it is not, turn the offer off and rethink the product pairing before paying for a higher tier.

Selleasy is developed by Logbase, a Shopify app developer. The subscription bills in USD through your Shopify invoice, alongside your plan fee. Whether your state taxes SaaS subscriptions varies, so check your state revenue department if it matters to your bookkeeping.

When Selleasy is the wrong app for your store

Three situations where the first hour is better spent elsewhere.

Very low order volume. If your store does five orders a month, one upsell offer will not move the needle. The post-purchase page appears five times. Even a modest take rate can significantly increase the number of orders. Spend the hour on product descriptions or ad creative instead.

You already use another upsell app. ReConvert, Honeycomb, and other apps occupy the same checkout surfaces. Running multiple upsell apps at once means multiple post-purchase pages fighting for the same slot, which Shopify's checkout does not support cleanly. Pick one.

Your checkout cannot render the offer. Some custom themes and most headless storefronts bypass the post-purchase page that Selleasy hooks into. If your store uses a headless architecture or a heavily modified checkout, the app may not fire. Test before you commit.

Frequently asked questions

Does Selleasy work with Shopify's new checkout extensibility?

Yes. Selleasy's post-purchase offers use Shopify's checkout extensibility framework, the same system Shopify built for app developers after retiring checkout.liquid. The older checkout.liquid-based upsell apps stopped working when Shopify migrated to checkout extensibility, but Selleasy was rebuilt for the new framework. Your store needs to be on a Shopify version that supports checkout apps, and all current plans do.

What is the exact setup time for Selleasy on a standard Shopify store?

About 20 minutes for a single post-purchase offer, assuming your products are already published and Shopify Payments is active. The process involves a few steps: installing and connecting, configuring the trigger and offer product, and placing a test order to confirm the upsell renders. A cart or product-page offer takes 30 to 60 minutes because it requires theme matching.

Can Selleasy be used on headless or custom storefronts?

Not reliably. Selleasy's post-purchase offer depends on Shopify's native checkout rendering the post-purchase page. Headless storefronts that use a custom checkout, like Hydrogen with a third-party checkout or a fully custom React storefront, often bypass that page entirely. The app's product-page and cart widgets may also fail to inject if your theme does not use Shopify's standard section rendering. Check with your developer before installing.

What is the maximum number of campaigns or offers allowed on each plan?

Selleasy does not publish a fixed cap on campaigns per plan tier, according to its App Store listing checked August 30, 2026. The free plan limits you to 50 orders per month across all offers combined, not per offer. Paid tiers are priced by monthly order volume rather than by campaign count, so the constraint is orders processed, not offers created. You can build as many offers as you want, but the plan limits how many times they can fire.
