## Short answer

Start new subscribers on a starter pack, move them to the full size from the second order, and make the first renewals easy to accept. With Zubs that means a switch subscribers see in advance, an introductory discount, a reward at a set order and a reminder before each charge.

## What makes supplement subscriptions different?

Supplements are taken every day, so a subscription is the natural way to buy them, and the first renewals decide whether it lasts. The first order was a deliberate choice. The second is a charge the subscriber didn't actively make. Many brands also start people on a trial or starter pack before the regular size, so the subscription has to change after the first order without surprising anyone. And brands that sell across borders need prices and currencies that fit each market.

## How do subscribers move from a starter pack to the full size?

With a [sequential flow](https://zubs.app/features/sequential-flows). You tell Zubs to replace the starter pack with the full size after the first order, and every new subscriber on that plan gets the full size from their first renewal on.

Nobody is surprised. The customer portal shows the upcoming change and the new price well before the order bills, and your team sees the same change in the Zubs admin.

## How do you keep new subscribers past the first renewals?

The [early-churn playbook](https://zubs.app/playbooks/reduce-early-subscription-churn) combines three things Zubs has built in:

- **An introductory discount** on the first recurring orders, on top of the regular subscription discount, which you can keep from returning subscribers.
- **A reward at a set order**, such as a free product with the third delivery, visible in the portal before it bills.
- **A reminder before each charge**, so no renewal comes as a surprise.

[Subscription analytics](https://zubs.app/features/subscription-analytics) then show how many subscribers cancel early and how many orders they stay for, so you can see after a few months whether it works.

Read the cancellation reasons closely, too. "Too much left" can mean a subscriber stocked up, or that they never got into the habit. A skip helps the first. The second needs a reminder of how and when to take the product, ideally right after the first delivery arrives.

## How do you present pack sizes on the product page?

**Subscription Packs** shows a product's sizes as tiles, such as a 30-day pack and a 90-day pack, each with its price and saving, and can show a price per capsule. For products sold in one size, the subscribe widget does the same job. See [subscription conversion offers](https://zubs.app/features/subscription-conversion-offers).

## Can you sell in several countries?

Yes. Each [subscription plan](https://zubs.app/features/subscription-plans) can be limited to the Shopify Markets it's sold in, so a euro plan and a Swiss franc plan sit side by side, and pack tiles follow the same limits. The customer portal and subscription emails come in several languages, including German, French and Spanish.

## How do you grow the basket over time?

You choose products that the portal recommends, and subscribers add them to an upcoming order as one-time items without changing their subscription. [noms+](https://zubs.app/customers/nomsplus), who sell vegan supplements for dogs and cats, use this to offer a second product to existing subscribers. Subscribers try it once and often keep it.

## Bottom line

A supplement subscription lives or dies in its first renewals. Zubs moves subscribers from a starter pack to the full size without surprises, makes the first charges easier to accept and sells the right plan in each market.
