01 · The portal
Customers fix their own subscription. You stop answering "can I skip a week?"
Lives where they already log in
The portal is part of Shopify customer accounts, with a link on the profile page. Reminder emails carry a 14-day login-free link, too.
Their schedule, inside your rules
Skip, pause, swap a product, change frequency or quantity, add an item to the next box. You set what's allowed.
A cancel flow that asks why
Customers pick a reason, see a skip or pause offer before they go. On the Free plan. Starter adds a one-time discount offer, and Growth adds the report of why people leave.
What's the main reason?
I have too much right nowIt's too expensiveI'm trying something else02 · Billing
Retries that respect your customer's card, and alerts before anything quietly breaks.
Idempotent charges. Every billing attempt has a unique key, so a network hiccup can't charge twice.
Breakage alerts. When a card or address change leaves a subscription unable to renew, you hear about it the same day.
Daily summary. One email: what renewed, what failed, what needs a click.
03 · Switching
Leave Seal on a Tuesday afternoon.
- Export your subscriptions CSV from Seal, Recharge, Appstle, Loop or Joy.
- Dry run. Tidepool matches customers and payment methods and shows exactly what will happen. Nothing is written.
- Import. Contracts keep their next charge dates, so nobody is billed early or twice.
- Undo the whole import if something looks off.

06 · Questions
Straight answers.
Do you take a cut of my subscription revenue?
No. Tidepool never charges a percentage of sales on any plan. You pay the flat monthly price, billed through your Shopify invoice, and Shopify Payments processes the charges as usual.
What happens if I go over my plan's limit?
Your existing subscribers keep renewing. We never pause or lock a subscription because you grew. We'll ask you to move up a plan, and that's it.
How do failed payments work?
A failed renewal is retried on day 1, 3 and 7, a hard cap of four attempts in total, then the subscription pauses and you're told. Every attempt carries an idempotency key, so a retry can't double-charge a customer.
How long does switching from Seal actually take?
Export your subscriptions from Seal (or Recharge, Appstle, Loop or Joy), upload the file, and read the dry-run report. For a typical store that's about five minutes. Nothing is written until you confirm, and an import can be undone.
Where do customers manage their subscription?
Inside the Shopify customer account they already use, plus a login-free link in every reminder email that expires after 14 days. No separate account, no password to forget.
Do Klaviyo and Mailchimp cost extra?
No. Both are included free on every plan, including Free. Klaviyo gets every subscription and charge event as a “Tidepool …” metric. Mailchimp gets each subscriber upserted into your audience with status tags (active, paused, cancelled, payment failed) and events for Customer Journeys. Both can also be used as actions in automations.
Will it slow down my storefront?
The subscribe option is a native Shopify theme app block that uses Shopify selling plans. There's no third-party checkout and no script you have to paste into your theme.
Is Tidepool on the Shopify App Store yet?
Our App Store listing is on the way. You can install it today from this page with your store's myshopify.com domain; it uses the same Shopify install and billing flow.
