Where Appstle is the better choice
We would rather you pick correctly than pick us.
- →Your monthly bill is what matters most and your subscription revenue is under $100,000 a month. Appstle's flat tiers with no transaction fee are cheaper at every volume in the table above.
- →You want a longer trial window. 14 days beats our 7, even with the money-back guarantee behind it.
- →You are already running Appstle and it is working. Migration is real work and inertia is a legitimate answer.
Where Subi is the better choice
The cases where the terms point our way even when the table does not.
- ✓Your subscription revenue is approaching or past $100,000 a month and you want pricing that scales without a negotiation.
- ✓You want a money-back guarantee on top of the trial. If it does not work out in the first 30 days, you get your money back, for any reason.
- ✓You want subscriptions, memberships and bundles from one app rather than assembling them.
- ✓You want your own app, portal or tools to read and change subscriptions. Subi's API and webhooks come with Starter, Subi and Subi Plus, while Appstle's listing asks you to contact them for APIs and webhooks.
If you do decide to move
Subscription migration is not a CSV import. Existing contracts have to keep billing on their own schedules, with their own discounts, asking as little as possible of your customers.
Talk to us first with your numbers. We will tell you which plan fits and what it will cost.
We map your existing plans, discounts and billing dates before anything moves.
Contracts transfer with their schedules intact, subscribers do not re-subscribe, and in most moves they do not re-enter payment details.
We stay on it through the first billing cycle, which is the one where problems actually surface.
Questions merchants ask
Will my subscribers have to sign up again?
No. Contracts move with their existing billing dates and discounts, and in most moves the saved payment method comes with them. Where the old app cannot hand a card over, that subscriber gets one email asking them to add a payment method.
Is Subi cheaper than Appstle?
No. At every volume in the table above, Appstle's flat tiers are cheaper. Subi's advantage is not on the monthly bill but on the pricing structure: our ladder has no revenue ceiling, and we include a 30-day money-back guarantee.
What happens when I pass $100,000 a month on Appstle?
Their listing says to contact them for Enterprise or API pricing. We do not know what those terms are because they are not published. Subi's Subi Plus plan covers that volume at $479 plus 0.40%, no negotiation needed.
