The Opportunity

Problem

Small retail business owners are frustrated by clunky loyalty programs in retail tech that fail to track customer purchases across multiple channels like in-store and online.

Solution

LoyalLinker gives customers a single ID or QR code to use at POS and online checkout for automatic point accrual. Business owners manage programs via simple dashboard with receipt photo upload fallback. It bridges channels without heavy integrations, perfect for small shops.
