Accrual Engine

Flexible point accrual across every purchase event

Define how members earn — by transaction, category, basket threshold, or campaign rule. One configuration powers every channel, no per-integration logic to maintain.

Event Schema

Accrual starts with a transaction event

Your POS, e-commerce, or app sends a structured event. Revlance evaluates it against your program rules and updates the member ledger — all within a single round-trip.

Features

Everything a production loyalty program needs

Transaction Events

Process purchase, return, exchange, and custom event types. Each event type has configurable accrual rules — returns can reduce balance or be ignored based on your policy.

Bonus Multipliers

Apply 2× or 5× multipliers based on tier status, product category, time window, or store location. Stack rules in priority order — Revlance resolves conflicts according to your precedence config.

Campaign Overrides

Create time-bounded campaigns that temporarily override base accrual rates — a weekend double-points event or a back-to-school category bonus — without changing your core program configuration.

Cross-Channel Deduplication

Idempotency keys prevent the same transaction from being accrued twice if your POS and e-commerce platform both fire events for a click-and-collect order. Configurable deduplication window.

Fractional Points

Support earn rates like 1.5 pts per dollar without rounding artifacts — Revlance stores fractional balances and rounds only at redemption, so members earn precisely what your program promises.

Real-Time Sync

Point balances update in under 200ms end-to-end. Webhooks notify your mobile app and POS display within the same transaction session — members see their new balance before they leave the register.
