Sell the subscription after they have already paid
The hardest part of selling a subscription is asking for it before the buyer trusts you. So ask after. On the page Shopify shows between the payment and the order confirmation, when the card has already gone through and the sale is banked.

Sell a subscription to a one-time buyer
They bought once. On the post-purchase page they get a one-tap offer to make it recurring, charged to the card they just used. No second checkout, no re-entered details.
On every plan, including the free one
Extend a subscription they just took
They subscribed for three months. Offer six at a better price, right after they pay, and the contract they already have is the one that gets extended. No second subscription, nothing to cancel.
Scale plan
Why nobody does the second one
Because Shopify will not let you. An order that already carries a subscription cannot have another one added or modified through the normal post-purchase route, and the Admin API keeps subscription contracts out of reach of apps that did not create them. Both doors are shut.
The open door is your subscription app's own API. We go through it, which is why this sits on the Scale plan: it is an integration with software you already pay for, not a feature we can switch on for everyone.
The detail that decides whether this is safe
When we move a plan from three months to six, the next charge date does not move. The buyer is not billed earlier and does not lose a cycle. We tested it by writing to a live contract and reading it back: one contract, longer term, same billing schedule.
That is the whole risk of this feature. An upgrade that quietly re-dates someone's billing is a refund request and a one-star review, and it would be your name on it, not ours.
Selling a subscription to a one-time buyer works on the free plan, on a live store. You can find out whether your buyers say yes before you pay anyone anything.
Install from the Shopify App StoreWhat we refuse to do
We never invent the frequency
The target frequency is derived from the selling plan in Shopify, not typed into a box. A "6" entered next to a quarterly plan would have extended real customers' commitments by a year without anyone noticing.
Prepaid plans are out
A prepaid plan has two cadences, delivery and billing. Merging them would change when a real person gets charged. We detect it and fall back to a normal checkout instead of guessing.
Consent is a gesture, not a default
Shopify requires the buyer to actively agree to a subscription. The button stays disabled until the box is ticked. Pre-ticking it is what earns apps their worst reviews, and we are not doing it.
No shipping settings, no offer
A subscription changeset needs a shipping charge and we cannot guess one. If you have not set it, the offer is not served. An absent shipping cost is not free shipping.
The rest of what the app does
Subscriptions are one branch of a post-purchase funnel. Three levels, seven offers, and every offer has its own two children: one for the buyer who just accepted, a different one for the buyer who just declined. Targeting on order total or on cart contents.
And because Shopify does not render the post-purchase page for every payment method, the offer also runs on the thank-you page, which renders on every order. On that surface it can be added to the order that already exists rather than opening a second checkout, so your buyer gets one parcel and you pay one shipping label.
You can click through the buyer screen yourself, accept and decline, on the demo page. Nothing there charges anything.
Pricing
Selling a subscription works on every plan, free included. Extending an existing one needs Scale, at 49.99 dollars a month, alongside the 3PL connector and A/B/C/D testing. Pro is 19.99 dollars a month, flat, with no commission on the revenue the app generates at any volume, and the price you install on is the price you keep. That is written into the Code this app is built under.
Free plan shows 100 offers a month on a live store. Enough to find out whether your buyers accept anything before you pay for a tool.
