Spas sell outcomes, not just minutes. Build journeys (e.g., “Detox 6: thermal + lymphatic x6”), romance packages (private suite + sparkling at the pool bar), or bridal programs (trial hair/makeup + nails + massage). Memberships (Weekday Wellness, All-Access Thermal, Local Resident) unlock day-pass access, priority booking, and retail discounts on serums and masks. Credits live on the profile, scan at spa reception or salon desk, and part-redeem across treatments or retail. Freeze rules, expiries and guest sharing are built in, so you can run seasonal pushes (Mother's Day, Valentine's) without admin tangles. Finance still smiles: deferred revenue is tracked and reported automatically.
