XFlow Pricing Release: Send Unlimited Emails & Pay as You Earn

We've made a significant decision. After months running XFlow as a free tool during our MVP phase, we're introducing paid plans, and we want to be completely transparent about why and what you get in return.

Our paid plans will take effect from August 6th, 2026. For full reference and features, come and check out our official pricing page! 

We Are Releasing New Pricing with Unlimited Emails on All Plans

The Reason We're Making This Change

When we launched XFlow, we set out to prove that merchants lose significant revenue when products go out of stock, and we could solve it. We've now helped 1,500+ stores recover sales through back-in-stock automation.

To scale XFlow to the level you deserve. More channels, smarter automation, better integrations. We need to build sustainably. That's why we're introducing paid plans, built around sellers like you and one principle: you only pay based on recovered revenue, not email volume.

XFlow now offers 4 plans:

Our Free plan:

• All core restock automation features
• Limited to 5 lifetime attributed orders
• 1 active campaign

Our Paid plans (Starter, Growth, Professional)

• Premium features based on your tier
• Monthly recovered revenue threshold included
• Usage fees apply only when you exceed your revenue threshold

No surprises. Charges are predictable and tied to your results, not activity.

Our Unlimited Emails Advantage Remains 

What's NOT changing: Unlimited back-in-stock email notifications on every plan, including the Free plan.

Here's why this matters:

There are back-in-stock apps that limit email volume or charge per send. You face caps like 500 emails/month on basic plans, or pay $0.01–$0.10 per email. With 2,000 subscribers, you either reach only a quarter of them or pay $200–$2,000 just to send notifications, before seeing a single sale.

XFlow has NO EMAIL LIMITS on any plan. Unlimited emails sent means you won’t have to choose between reaching your subscribers and keeping costs down as much as you used to.

More about XFlow pricing: There is our fee calculator that helps you find out exactly how much you will pay based on the sales generated from our app. This will be most helpful when you are exceeding the revenue milestone marked in our pricing. Also, this fee calculator will help you choose the most money-saving plan based on your sales volume. Take a look at it right here:

Understanding Your Pricing: How Our Plans Work in Real Life?

Let’s talk about your recovered revenue first. Note that recovered revenue includes only orders from customers who received your XFlow back-in-stock notifications and completed a purchase. And you can track this on XFlow. And one more thing: Like any other app, you pay according to the Shopify monthly cycle. Each cycle counts from the 1st day of each month. 

Orders from other sources, such as Facebook ads, organic search, and physical stores, don't affect your bill.

You always pay the base fee for your plan. You only pay additional usage fees if you exceed the included recovered revenue threshold. 

However, we understand that you’ll have many more scenarios and may be wondering how our pricing works. Now, take a look right below and see if any of the following matches your case. 

Real-life scenario 1: You upgrade from Free → Starter (first time ever, trial starts)

Setup: Merchant has never subscribed to a paid plan. Currently on Free with $2,500 revenue recorded.

Revenue generated before and during trial is never charged. Billing counter starts at $800 after the trial ends.

Real-life scenario 2: You upgrade from Starter to Growth plan (within quota of $800)

Setup: Merchant on Starter, revenue $800 (within $1,000 quota, no charges yet). Upgrades to Growth.

Since $800 is within Starter's quota AND within Growth's quota, upgrading has no billing impact. The first charge under Growth fires at $3,001.

Real-life scenario 3: You upgrade from Starter to Growth plan (heavily exceeding $3,200, multiple blocks charged)

Setup: Merchant on Starter, revenue $3,200. Has crossed $1,000 ($7), $2,000 ($7), $3,000 ($7) → total $21 charged.

Prior $21 charge locked. Growth quota is $3,000 — merchant is already at $3,200, so the system waits for $4,001 before charging at Growth rate ($5).

Real-life scenario 4: You downgrade from Growth to Starter (exceeding the new quota of $3,200, 1 block charged)

Setup: Merchant on Growth, revenue $3,200. Crossed $3,000 → $5 charged. Downgrades to Starter.

$5 charge locked. After downgrading to Starter, each subsequent milestone costs $7 instead of $5; downgrading while exceeding quota is more expensive.

Real-life scenario 5: You downgrade from Paid to Free but upgrade to Paid (same month)

Setup: Growth → Free at $3,200 (1 block charged) → upgrades back to Starter at $5,800.

Skipped milestones ($4,001, $5,001) are gone forever. System resumes at $6,001, and the next unskipped milestone is charged at the Starter rate.
