What bulk actually means here
Three different things get called bulk store credit, and they are not interchangeable.
CSV upload. You have a list, one row per customer, amounts that may differ. This is the right shape for apology campaigns, imported lists, and anything where the amounts are not uniform.
Filter or segment issuance. You have a rule, not a list. Everyone who has not ordered in 90 days gets $25. This is the right shape for recurring campaigns because the rule can be rerun next quarter.
Rules-based automation. Credit issues itself when something happens, like a purchase or a review. This is cashback, not a campaign, and it is a different product category.
Most merchants asking for bulk store credit want the first two. Koin is excellent at the third.
Why Shopify does not do this itself
Shopify shipped native store credit on Plus, and it is a good implementation: balance on the customer record, applies automatically at checkout, no code. What it does not have, on any plan, is a way to touch more than one customer at a time.
So on Plus you get credit but not bulk. Below Plus you get neither, and an app supplies both.
The comparison
| App | Bulk method | Free plan | Paid | Works below Plus |
|---|
| Bulk Store Credit | CSV plus filter | 20-row CSV plus widget | $49/mo | Yes, all plans |
| Rise.ai | Bulk tools inside a loyalty suite | None | $19.99 to $599/mo | Yes |
| Koin | Rules and automation | Yes, currently free | Free | Yes |
| Growave | Loyalty module | Limited | $49 to $349/mo | Yes |
The app matters less than the amount. At an $80 average order value, a $25 credit against a 90-to-365-day lapsed segment is the standard shape and it works. A $60 credit against the same segment buys orders at a loss.
Get the amount right first, then pick the tool that can issue it to the list you have. Full method in how to bulk issue store credit on Shopify via CSV.
If you need transferable value instead
If the value has to be handed to another person, printed, or sold to a company for its staff, store credit is the wrong instrument because it is locked to a customer record. That is gift card territory. See best Shopify bulk gift card apps and the bulk gift cards guide.
