Run subscriptions, and keep the subscribers.

An engine and a retention layer, in one app

Most subscription apps stop at the billing. Mainstay runs the subscriptions and then does the harder job: keeping the subscribers you worked to win.

• The engine. Sell subscribe and save on your products, bill on Shopify’s own subscription contracts and Shopify Payments, and let customers skip, pause, resume, and cancel from their own portal.
• The retention layer. Recover failed payments the smart way, offer the right alternative when a customer goes to cancel, and see your churn, recovered revenue, and what needs your attention in one dashboard.

Recover failed payments the smart way

A failed charge is not always a lost customer. Mainstay reads the decline and does the right thing instead of blindly retrying a dead card.

• Soft declines retry on your schedule. You set the days between retries and how many there are. The plan you see is the plan that runs.
• A dead card asks for a new one. On a hard decline, Mainstay sends the customer a secure link to update their card instead of wasting retries. A card that needs authentication is handled the same way.
• Your problems come to you, not the customer. A configuration or out-of-stock failure alerts you and never chases the customer for a payment that was never theirs to fix.
• Every charge fires once. The billing scheduler is exactly-once, so a hiccup on our side can never double-bill a subscriber.

Save the subscriber at the moment they leave

When a customer opens the cancel flow in their portal, Mainstay asks why, then offers the best alternative you allow for that reason before the subscription is lost.

• The right offer for the reason. Pause, skip a cycle, swap the product, or a discount, matched to why they are leaving.
• Discounts with guardrails. Set the percentage, a lifetime cap per subscriber, and a minimum tenure, so the cancel flow cannot be farmed for repeat discounts.
• Honest every step. If there is nothing suitable to offer, Mainstay cancels cleanly. It never claims to have applied something it did not.

Priced fairly, and native

• Flat pricing, not a percentage of your revenue. Mainstay does not take a cut of every recurring order the way the incumbents do.
• Nothing injected into your theme. Subscriptions run on Shopify’s native contracts and checkout, so there is no fragile script added to your store.
• The subscriptions are yours. They are Shopify’s own subscription contracts, on your store, not trapped inside a vendor’s system.

How it works

1. Add a subscribe and save plan to a product: pick a weekly or monthly interval and the discount.
2. Customers subscribe at your normal checkout. Mainstay creates the contract and bills it on schedule.
3. Mainstay recovers failed payments, intercepts cancellations with save offers, and shows you what it recovered.

Built native, and honest about what it does. Mainstay runs on Shopify’s own subscription contracts and Shopify Payments, with nothing added to your theme. Coming soon to the Shopify App Store.
