Why average order value
The cheapest growth lever you are not pulling
Conversion rate and traffic get all the attention. Order value is the only one of the three you can move without spending a cent more on acquisition.
The cart is where money leaks
Most stores treat the cart as a receipt. It is the highest-intent surface you own, and the cheapest place to add margin.
Post-purchase is unowned territory
The window between "order placed" and "parcel shipped" generates support tickets, cancellations and returns — or a second sale.
The install path
Don't guess which leak to fix. Audit it.
Traffic is expensive. Another app on a healthy page is noise. Paste a store or a product URL — password-protected stores work too — we rank the constraints that can stop the sale, then name the Ninety9 app that owns each miss. One leak, one install, not a suite dump.
- Paste a store or product URLDomain is enough. Homepages pick a bestseller. No Shopify admin login. Password-protected stores work too — paste the store password if we ask.
- Get a punch listScore, ranked fails, before/after add screenshots.
- Install the ownerEach miss links the app that fixes it — Addly, Addy, Goalify, Monet or Reviso.
The suite
One app for every stage of the buying journey
Each app solves one job properly and plugs into the others. Run one, or run all five and cover the funnel end to end.

Product bundles
Catch the moment before it is lost
Monet shows upsells, cross-sells and bundles as popups triggered by the three moments that matter most: add to cart, checkout initiation and exit intent. Add AI recommendations and you capture revenue that would otherwise walk out the door.
- AI product recommendations inside every popup, running on autopilot
- Three triggers that cover the whole funnel: add to cart, checkout, exit intent
- Popup templates for bundle, cross-sell and add-on offers
- Multi-currency and translations so you can lift revenue internationally
- Analytics that show exactly which popup converts and which one does not

Order editing
Turn "cancel my order" into a bigger order
Reviso lets customers edit their orders after checkout — address, products, quantities, variants — before anything ships. Support tickets fall, cancellations fall, returns fall, and AI upsells turn the edit screen into a second revenue moment.
- Cancellation deflection flow with incentive discounts or a free gift
- Post-purchase AI recommendations and recently viewed products to lift AOV
- Fewer returns because shoppers fix mistakes before fulfilment, not after
- Smart rules controlling edits by country, customer tag and order conditions
- Change address, shipping method, variants or quantities without a support ticket

Which app should you start with?
Pick by the stage of the journey you want to improve. They stack, so adding a second app later is additive rather than duplicated.

The full-funnel stack
Four moments decide how much a session is worth. Ninety9 covers all four.
1. Product page
Addly adds bundles, quantity breaks and frequently bought together before the shopper ever reaches the cart.
2. Cart
Addy replaces the default drawer with upsells, reward goals and delivery estimates. Goalify adds the progress bar.
3. Exit & checkout
Monet catches add-to-cart, checkout-initiation and exit-intent moments with a single targeted offer.
4. Post-purchase
Reviso turns edits, address changes and cancellations into self-service — and a second upsell.

FAQ
Questions Shopify merchants ask us
How do I increase average order value on a Shopify store?
Add one offer at each high-intent moment: a bundle or quantity break on the product page, an upsell and a free-shipping goal in the cart, a single targeted popup at add-to-cart or exit, and a post-purchase offer after payment. Start with the moment where your funnel leaks most, measure for two weeks, then add the next.
Which Ninety9 app should I install first?
If shoppers buy one item at a time, start with Addly for bundles and quantity breaks on the product page. If carts are abandoned or small, start with Addy (AI cart drawer) and Goalify (free shipping progress bar). If you want one well-timed offer without touching the theme, start with Monet. If support is drowning in order changes, start with Reviso.
Do the Ninety9 apps work together?
Yes. Each app owns a different moment in the buying journey — product page, cart, checkout intent and post-purchase — so they stack without showing duplicate offers. You can install one and get the full benefit, then add another later.
Are Ninety9 Shopify apps free?
Every app has a free plan or is free to install. Where paid tiers exist they are billed through Shopify, start from a few dollars a month, and step up with your store’s monthly order volume.
Will these apps slow down my Shopify store?
No. Each app is a Shopify theme app extension: it loads asynchronously, stays out of the Largest Contentful Paint path, makes no edits to theme.liquid and uninstalls cleanly. You enable it from Online Store → Themes → Customize → App embeds.
Do I need a developer to set up upsells or a cart drawer on Shopify?
No. Install from the Shopify App Store, switch the app embed on in the theme editor and configure offers in the app. Most merchants are live in under ten minutes, and support replies from a developer, not a script.
How do I find out what is wrong with my Shopify product page?
Run the free CRO Audit for Shopify stores (https://ninety9.dev/cro-audit/). Paste your store or product URL and it checks the product page and cart the way a shopper sees them, ranks what stops the sale, and names the fix. No login and no card required.
Start with one app, free
Every Ninety9 app has a free plan and installs in a couple of minutes. Pick the moment in your funnel that leaks the most and fix it first.
Every app installs from the Shopify App Store. No theme code, no developer needed.
