Selling plans in a few clicks
Pick a frequency in days, weeks, months or years and a discount by percentage, fixed amount or flat price. Start from a template — Subscribe & Save, tiered savings, weekly delivery — or write your own.
Shopify subscriptions
Sell subscriptions without babysitting the billing
SubFlow builds the selling plans, charges every renewal, retries the cards that fail, and gives subscribers a place to skip, pause or change a delivery themselves — so the only thing left on your desk is the products.
- Native Shopify subscription contracts
- A theme app block — no theme code
- Free to install
Every charge runs through Shopify Checkout on the card already on file. No second payment processor.
The problem
Recurring revenue is not recurring work
Subscriptions are supposed to run themselves. Most of the effort is in the parts that go wrong after checkout.
Renewals waiting on someone to charge them
Due billing cycles are charged for you, every hour
A failed card nobody chases
Retries on your own day pattern, then pause or cancel
Every skip and pause arriving as a support email
Subscribers do it themselves from their account
Cancellations that leave without a word
A reason and a save offer first, both logged
Features
What SubFlow runs for you
Built on Shopify's own subscription APIs, so plans, contracts and payments stay where your store already keeps them.
Billing that runs itself
Shopify does not charge subscription contracts on its own. SubFlow does, on a schedule, and reads every success and failure back from Shopify's billing-attempt webhooks.
Dunning you control
Failed payments retry on your own day pattern — 1, 3, 5, 7 and 10 days by default, up to five attempts. When the retries run out the subscription pauses, cancels, or is left alone: your rule, not ours.
A self-service customer portal
In their Shopify account, subscribers pause, resume, skip the next delivery, change frequency or quantity, add a one-off product to the next order, and edit what is in their box.
A save offer before the cancel
Cancelling asks why first, then offers a discount, a pause or a skip based on the answer. Every reason and outcome lands in a log you can read.
Nine emails you never write
Renewal reminders, payment receipts and failures, dunning nudges, pause and resume confirmations, cancellations, skipped out-of-stock lines and win-backs — each one switchable, in your sender name and brand colour.
How it works
Three steps, then it is running
Create a plan
Choose an interval and a discount, or start from a template. SubFlow creates the Shopify selling plan group and attaches the products you picked.
Add the block to your product page
The subscribe-and-save widget is a theme app block. Drop it into your product template in the theme editor — nothing is written into your theme files, and it leaves with the app.
Leave it alone
Charges, retries, emails and the customer portal carry on without you. The dashboard tracks MRR, active subscribers, churn and average order value, and exports to CSV.
Use cases
What merchants sell with it
Replenishment
Coffee, supplements, pet food, refills — anything that runs out. One subscribe-and-save discount, or a bigger one for a longer interval.
Curated boxes
Build-a-Box: you define the pool of products and the number of slots, the customer fills the box on the product page and can change next month's from their account.
Memberships and access
A recurring charge with no shipping decision to make — the contract renews, the emails go out, and cancelling still goes through the save offer.
Rent-to-own
An optional module: a deposit, a fixed number of monthly payments, an agreement the customer signs online, and a buyout or hand-over at the end of the term. Off until you switch it on.
Pricing
One plan, and it is free
There is no paywall inside SubFlow and no feature held back for an upgrade.

FAQ
Questions merchants ask
Does this use Shopify's native subscriptions?
Yes. Your plans are Shopify selling plan groups and each subscriber is a Shopify subscription contract, charged through Shopify Checkout on the payment method already saved there. No money moves through a second processor, and if you ever remove SubFlow the contracts remain Shopify's.
What happens when a renewal payment fails?
Shopify sends the failed billing attempt, the subscription enters dunning, and SubFlow retries on the day pattern you set — 1, 3, 5, 7 and 10 days out of the box, up to five attempts — emailing the customer along the way. If the retries run out, it pauses the subscription, cancels it, or does nothing, whichever you chose.
Can customers manage their own subscriptions?
Yes, in the customer account area. They can pause, resume, skip the next delivery, change the frequency or quantity, add a one-off product to the next order, edit the contents of a box, and cancel — which is where the save offer appears.
Do I have to edit my theme?
No. The product-page widget is a theme app block you place in the theme editor, and the customer portal is a Shopify customer-account extension. Nothing is injected into your theme files and nothing is left behind if you uninstall.
What if something in a subscription goes out of stock?
SubFlow checks stock before it charges and does what you told it to: hold the whole cycle until the item is back, skip just that line and email the customer, or substitute a variant you nominated in advance.
Can customers build their own box?
Yes. A Build-a-Box plan has a slot count and a pool of eligible products; the customer picks their box on the product page, it becomes a normal subscription contract, and they can change what is inside before the next charge.
