How it works
Referrals that run themselves
Three automatic steps turn one sale into the next. No spreadsheets, no manual codes.

A customer buys
After any order, Gluesale emails your customer their own unique referral link — automatically, with your branding.
-
2
They share it
Friends tap the link and instantly unlock a first-order discount code, created live in your Shopify store.
-

Everyone wins
When the friend checks out, your original customer is automatically rewarded with a thank-you discount. Repeat.

FAQ
Questions, answered
How much does Gluesale cost?
Your first 10 successful referred customers are completely free. After that it's a simple $5 per successful referred customer — you only pay when a referral actually converts. A monthly usage cap protects you from surprises and can be raised anytime.
How do referral rewards work?
When a customer buys, Gluesale gives them a unique referral link. Their friend gets a discount on their first order, and once that friend purchases, the original customer is automatically emailed a thank-you reward. Both are real Shopify discount codes created automatically.
Can I customize the rewards?
Yes. Set the friend and referrer rewards as a percentage or fixed amount, choose validity windows and minimum-order rules, and update them anytime. Changes go live instantly.
What data does Gluesale access?
Only what's needed to run referrals: read access to customers and orders, and permission to create discount codes. Gluesale handles Shopify's data-request and redaction webhooks.
Will it slow down my store?
No. Gluesale adds no scripts or extra weight to your storefront. It works entirely through Shopify's API behind the scenes, so your site's speed is completely unaffected.
How do I install Gluesale?
Add Gluesale from the Shopify App Store, approve the permissions, and your referral program is live. No theme code or developer setup required.
