Back-in-Stock is an opt-in add-on for stores that want to notify shoppers via WhatsApp when a product is restocked. It is billed as a monthly tier with an included subscriber limit. Above the included limit, overage is charged at $0.02 per additional subscriber. Enterprise core plan includes the Starter tier (250 subscribers) by default — every other plan opts in by purchasing a tier.

Enterprise core plan ($399/mo) includes Back-in-Stock at the Starter tier (250 subscribers) at no extra cost. If you exceed 250 subscribers as an Enterprise customer, you can upgrade to a higher BIS tier — only the difference is billed.

​
Overage

Above the included subscriber limit, overage is billed at $0.02 per additional subscriber per month. This is added as a usage-based line item on top of your monthly tier subscription.
We recommend monitoring subscriber count in Billing → Usage and upgrading to the next tier when you hit 80–90% of the included limit — it almost always works out cheaper than paying overage.

​
Choosing the right tier

1

Check current subscriber count

Go to Billing → Usage → Back-in-Stock to see your current subscriber count.
2

Pick the smallest tier that covers you

Start one tier above your current count if you expect modest growth. Skip tiers if you’re seasonal or running a launch.
3

Watch for overage early

Subscribers can pile up faster than expected after a viral product or restock event. The Usage page shows a 30-day trend.
4

Upgrade when 80% full

A tier upgrade is cheaper than accumulating overage above ~10% of the included limit. Upgrades take effect immediately.

​
Where to track Back-in-Stock usage

Go to Billing → Usage in the Galantis app to see:
  • Current subscriber count vs included limit
  • 30-day trend
  • Overage units and cost (if applicable)

​
How Back-in-Stock appears on your invoice

Back-in-Stock charges appear on the Galantis (Shopify) invoice as:
  • “Galantis WhatsApp — Back-in-Stock [tier name] — $X / month”
  • “Galantis WhatsApp — Back-in-Stock Overage — N subscribers × $0.02”
For Enterprise customers, the included Starter tier does not appear as a separate line item — it’s part of the core plan price. Only upgrades above Starter and overages are billed separately.

FAQ

A subscriber is a unique customer who has opted in to receive Back-in-Stock notifications for one or more products via WhatsApp. The same customer subscribing to multiple products counts as 1 subscriber.
Subscribers remain on your list until they opt out, are unsubscribed automatically due to inactivity, or are manually removed. See Subscription lifecycle.
Yes — each delivered Back-in-Stock notification consumes 1 Conversation credit, drawn from your plan allowance and Conversation tier. The Back-in-Stock add-on covers the subscriber list management itself; the actual delivery uses the same credit pool as campaigns and automation flows.
Yes. Upgrades take effect immediately and are prorated for the remainder of the current Shopify cycle. Downgrades are typically applied at the start of the next billing cycle to keep invoicing predictable.
