In their own words
Loyalty Interchange Protocol
Loyalty Interchange Protocol (LIP) is an open-source loyalty platform and vendor-neutral transaction protocol for restaurant technology teams that own integration work. Its checkout lifecycle includes member lookup and enrollment, balances and ledger history, order evaluation, accrual, redemption, reversal, and refund-safe adjustments. Its restaurant order model represents items, modifiers, discounts, fees, taxes, tips, tenders, and totals across channels such as drive-thru, kiosk, web, mobile, pickup, delivery, and catering. Supported program types include points, visits or stamps, wallet credit, paid membership, and hybrid multi-account programs.
The `/platform/v1` API covers profiles, consent, behavioral events, segments, campaigns, connectors, imports, analytics, and attribution. The maker provides an Apache-2.0 reference stack for self-hosting with Docker Compose or Node.js 22 and newer. Storage described includes SQLite-backed local storage and tenant-scoped PostgreSQL for multi-instance use. Customer sign-in remains external. LIP 0.2.0 is described as pre-1.0 infrastructure, not a turnkey no-code marketing service; CSV member imports are limited to 1 MiB and 1,000 rows.
Slant Loyalty
Slant Loyalty is a loyalty feature in Slant POS for restaurant customers. Restaurants set a reward percentage on purchases; customers who join earn points on orders and can later convert them into discounts. Staff can enroll customers and enter their details in the POS during a sale, so points can accrue on the first purchase. Customers can check their remaining balance on printed or emailed receipts. Restaurants can use the program across their locations and chains, and a loyalty report provides real-time information about program performance, sales impact, and loyal customers. Slant says basic loyalty functionality is included in Slant POS without extra apps, equipment, or fees. The service is available on Android and the web, and includes points rewards and offer campaigns. The Free Forever plan is free and includes 100 orders per month, limited invoices, and email support. The Paid plan is $32 a year, billed per month per outlet billed annually, and includes unlimited invoices, loyalty, support seven days a week, and remote setup and onboarding. A 14-day trial is listed.
