Shopify referral discount program.
Capped on both sides.

A Shopify referral discount program is the cheapest acquisition channel you have — until somebody refers a friend who buys $800 worth of product. A $30 cap on each side keeps the advocate reward and the new-customer discount predictable, no matter how big the referred cart.

    Why a Shopify referral discount program needs two caps

    Most referral programs reward both the advocate and the new customer. Without a cap, a single big order pays out twice — 15% to the advocate as store credit, 15% off for the new buyer. A Shopify referral discount program without caps turns one $800 checkout into $240 of margin burn for a single acquisition, and the advocate who refers a whale ends up more expensive than a paid ad.

    02

    A Shopify referral discount program that caps each side independently

    With Nex Discount each side carries its own $30 ceiling, so the Shopify referral discount program costs you at most $60 per successful referral — regardless of the cart size. Finance can budget against advocate count rather than cart distribution, and CAC stays bounded to a line item you can actually forecast before the quarter starts.

    03

    Ship a Shopify referral discount program on unique codes at scale

    Generate one capped code per advocate and run the whole Shopify referral discount program natively: Nex tracks attribution by code prefix and rolls redemptions up inside your Shopify analytics. No extra referral app, no third-party dashboard, no duplicate source of truth — just unique codes with the cap baked in.
