Your customers want to spend more. Your checkout won't let them.
Right now, someone's at your checkout with $347 in their cart, wondering if there's a better deal. In 8 seconds, they'll check your competitor. Unless they see the offer first.

Your checkout apps are fighting each other.
CheckoutOS is Chargezen’s checkout app for Shopify stores: offers after purchase, rewards points, pre-orders, bundles and checkout add-ons in one app. Every separate app you add to checkout slows it down, clashes with the others and splits up your reports. The real cost isn't the monthly bills. It's the sales you lose to a slow, clunky checkout.
A slower checkout
Every checkout app adds a fraction of a second to load. Three apps can add a full second.
Numbers that don't add up
Each app takes credit for the same sales. The upsell app says +$12K, the loyalty app says +$8K. The real increase is often half that.
A patchwork look
Customers see your brand, then someone else's upsell box, then a different rewards widget. It looks pieced together, and shoppers notice.
Constant fixes
Shopify updates break checkout apps. With three or four of them, something always needs fixing, and Black Friday is stressful.
This is CheckoutOS.
What if one app ran your whole checkout?
One app, one set of numbers, and every sale counted once. Every offer, discount and reward point works together, because it's all one app.
Zero conflicts
One app runs your upsells, rewards, checkout add-ons and thank-you page.
Every sale counted once
Every upsell, reward redemption and reorder is credited to what actually made it happen.
Faster checkout
One light app instead of 3 or 4 that compete. Your checkout loads faster.

What each part adds
A closer look
Offers, checkout blocks, rewards, pre-orders, discounts, bundles and cart rules. One app, one price.
One-click offers after they pay
Right after "Pay now" is when shoppers are most likely to add something. Show an offer they can accept with one click, without typing their card again.
- Pick the product. A product you choose, or the most or least expensive item they just bought.
- Show it to the right people. Target by what is in the order, order value, customer tags, first-time buyers or country.
- Build the page. Countdown timers, reviews, trust badges and FAQs, with a percent or dollar discount.
Add-ons built into Shopify checkout
Pick a block, fill it in and publish. It goes into Shopify's own checkout editor, so Shopify updates don't break it.
- Upsells in checkout. Products shoppers can add before they pay.
- Trust and reviews. Trust badges and reviews right where shoppers decide.
- Notes, banners and checks. Gift messages, image banners, quantity and variant changes, and an address check before payment.
Points where people spend them
Your loyalty program shouldn't live in a page customers never visit. Show points as people buy, and let them use them right there.
- Points this order earns. "You'll earn 135 points" right in checkout, with a progress bar to the next reward.
- Redeem in one tap. Customers see their balance and apply a reward without hunting for a code.
- Your whole program. Ways to earn and redeem, referrals and tiers, all in the same app.
Sell it before it arrives
Take orders for products that aren't in stock yet. Built on Shopify's own pre-order plans, so it works in your normal checkout.
- Deposit or full price. Take a percent or a fixed amount at checkout, or the full price up front.
- Balance charged for you. On a date you set or a set number of days after checkout.
- Failed charges handled. Retries on a schedule you choose, then hold, refund or keep the deposit.
Discounts Shopify codes can't do
Order, product and shipping discounts that run inside Shopify checkout, with rules you set in plain menus.
- Tiered and volume. Buy 2 get 10% off, buy 4 get 20% off, or a set price per item.
- Automatic or triggered. Apply on their own, or from a link, a UTM source or a cart offer.
- Who and when. One-time or subscription orders, customer tags, minimums, use limits and dates.
Bundles that check out cleanly
Cart transforms turn separate items into one bundle, or one bundle into its parts, before the order is placed.
- Merge. When every item is in the cart, they become one bundle line with your discount.
- Expand. Sell one bundle product and ship its parts as separate lines.
- Update lines. On Shopify Plus, change the title, image or price shown for chosen variants.
Stop the orders you can't ship
Checkout rules catch problem orders before they are paid for, with a message you write.
- Where you ship. Limit subscriptions or certain products to the countries you choose.
- Weight and address limits. Set weight limits by country and keep address lines short enough for your carrier.
- Blocked customers. Stop orders from emails or customer tags you have blocked.

Why one app beats five
Separate checkout apps clash. One app that does it all keeps adding up.
Offers after purchase
Offers based on what the customer bought, subscribes to, has in points and looked at. Orders are 15-25% bigger on average.
Separate apps: Upsell app can't see loyalty points or subscription status. Every recommendation is a generic guess.
Rewards at checkout
Points, rewards and referral credit shown at checkout, when they matter most. Customers use rewards 3 to 4 times as often.
Separate apps: Rewards live in a separate app that 70% fewer people use than rewards shown at checkout.
Bundles and checkout add-ons
One app runs upsells, bundles, checkout add-ons and the thank-you page, so nothing clashes.
Separate apps: The bundle app clashes with the upsell app, and checkout add-ons fight for space.
Reorders and subscriptions
AI times reorder reminders from past orders, and offers one-time buyers a subscription at checkout.
Separate apps: Reorder reminders need a separate tool that can't show anything at checkout.
Most Shopify Plus brands spend $500-$1,200/month across 3 or 4 checkout apps. CheckoutOS replaces them from a $99/month entry plan with no revenue share.

Why we price it this way
Selling more at checkout shouldn't cost you more. Every upsell, reward point and reorder reminder is supposed to make you money, not cost you more in software fees. You pay the same as your sales grow.
How fast it pays for itself
Most brands cover the first month of CheckoutOS with their first week of offers after purchase.

Our 90-day promise
Here's the math: CheckoutOS is $99 a month. The average order grows by $34. At 100 orders a month, a few accepted offers cover the cost. Most brands hit payback in week one. But let's say you're different. Let's say 90 days pass and you're not at 10x.
We'll get on a call, audit your setup, rebuild your offer strategy, and keep working until the numbers work. We've done this 200+ times. We know what converts.
Still not seeing results? $500 service credit, no questions asked. But in our experience, that's never happened.
