Where Loop is the better choice
We would rather you pick correctly than pick us.
- →You are pre-launch or very small and want to stay free indefinitely. Loop's free tier runs to 50 active subscriptions with no clock on it; ours is limited to development stores.
- →You want longer to evaluate before paying. 14 days beats our 7, even with the money-back guarantee behind it.
- →You have already built around Loop and it is working. Migration is real work and inertia is a legitimate answer.
Where Subi is the better choice
The cases where the table above and the terms both point our way.
- ✓You are past Loop's free plan and the monthly bill starts to matter: $29 to begin against Loop's $99 Starter.
- ✓Your subscription revenue is growing. Our rate steps down to 0.40%; theirs stops at 0.75%, and on a six-figure month that difference is most of a salary.
- ✓You want subscriptions, memberships and bundles from one app rather than assembling them.
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, without asking your customers to re-enter anything.
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 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. Asking subscribers to re-enter payment details is how a migration loses customers, so the process is built to avoid it.
Is Subi cheaper than Loop?
At every volume in the table above, on the plan that fits, yes, though the size of the difference is not a straight line. Around $11,000 a month the two of us cost within a few dollars of each other, because that is where our own plan steps from Starter up to Subi. Past that the gap opens as our rate keeps stepping down: by $100,000 a month it is about $220 every month. A store with 50 or fewer active subscriptions pays nothing on Loop's free plan, which is less than any paid Subi plan.
Are either of you charging per-order fees?
No. Neither Subi nor Loop charges a flat fee per order. That is a real difference from the older incumbents, and it is worth checking on any app you compare.
