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. 90-day money-back promise Order summary 3 items • $147.00 Checkout Premium Wellness Bundle Qty: 1 • $127.00 Just for you Add Recovery Serum for 40% off $45 $27 You'll earn 147 points on this order! Only 53 more to unlock $10 reward Order total $174.00 +$47 per order The cost of too many checkout apps ## Your checkout apps are fighting each other. Every 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. Studies show every tenth of a second costs about 1% of sales. ### 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. ### What if one app ran your whole checkout? One app, one set of numbers, and every sale counted once. 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. This is CheckoutOS. Every offer, discount and reward point works together, because it's all one app. 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. ## Meet CheckoutOS: more from every order One app for upsells, rewards, reorder reminders, checkout add-ons and chat, with one set of numbers. ### After purchase One-click upsells after checkout ### Rewards Points shown at checkout ### Reorders Reminders when it's time to reorder ### Checkout add-ons Built into Shopify checkout ### Discounts Flexible discount rules ### Checkout chat Answers questions before they buy ### Bundles Product bundles ### Analytics One set of numbers ### What's different Every offer, prompt and message knows the same customer. No clashing apps. No doubled-up discounts.

One app that does it all keeps adding up. ### Offers after purchase Separate apps Upsell app can't see loyalty points or subscription status. Every recommendation is a generic guess. CheckoutOS Offers based on what the customer bought, subscribes to, has in points and looked at. Orders are 15-25% bigger on average. ### Rewards at checkout Separate apps Rewards live in a separate app that 70% fewer people use than rewards shown at checkout. CheckoutOS Points, rewards and referral credit shown at checkout, when they matter most. Customers use rewards 3 to 4 times as often. ### Bundles and checkout add-ons Separate apps The bundle app clashes with the upsell app, and checkout add-ons fight for space. CheckoutOS One app runs upsells, bundles, checkout add-ons and the thank-you page, so nothing clashes. ### Reorders and subscriptions Separate apps Reorder reminders need a separate tool that can't show anything at checkout. CheckoutOS AI times reorder reminders from past orders, and offers one-time buyers a subscription at checkout. $500-$1,200/mo Industry average for 3-4 checkout tools vs. $99/mo CheckoutOS, no revenue share ## $99 a month. No cut of your sales. Everything for your checkout at one monthly price, with no setup fee and no cut of your sales. Monthly plan $99 /month No setup fee. No revenue share. #### Setup includes * We install the whole thing * Offers after purchase, set up for you * Loyalty points checkout integration * Reorder reminders set up * Checkout add-ons turned on * Discount rules set up * Offer testing set up * 30 days of priority support #### Plan includes * Unlimited orders * Unlimited upsells * All features * All updates * Email support * Community access No "per transaction" fees. No "revenue share" tiers. No surprise invoices. ### 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. 15-25% Bigger orders, on average 7-14 days To pay for itself 50x+ Return in the first year [Work out your return](https://chargezen.com/roi-calculator) ## Brands that grew their checkout sales ### High-Volume Nutraceuticals Sports Nutrition Payback: 6 days +31% Bigger orders 27% Took the offer $47K New Revenue (90 days) $24K/yr Saved on apps > "First week, CheckoutOS paid for itself.
