Wallet & Loyalty

Your points economy — clean, in one place.

GRVITY runs your points program in a single, auditable place: one immutable ledger, one consistent balance — no second wallet, no silent corrections.

Every entry lands immutably in the ledger — the balance stays consistent at all times.

How the wallet works
01

Credit

Fixed reason codes (signup, win-back, referral …) post cleanly.

02

Debit

Checkout debits and FIFO expiry run through the same ledger.

03

Reconcile

A daily consistency check reconciles balance and ledger.

No second wallet, no silent corrections — every move is reasoned and auditable.

One ledger

One authority for the balance — not two.

The wallet lives in the retention system, not in parallel in the backend. So there's exactly one state of truth — auditable down to the single entry.

  • GRVITY is the sole authority for the balance.
  • No update or delete on transactions.
  • Every entry with reason, source and balance snapshot.
  • Idempotency prevents double-posting on retries.

Points you and your customers can trust."
