Saldo Sub
Saldo Sub is your spendable in-app balance. It is custodial, denominated in IDR, and used across the Akupon app for:
- Redeeming vouchers from the Merchant Marketplace
- Paying merchant invoices (Premium subscription, hybrid checkout)
- Buying digital products & paying bills (PPOB)
- Receiving contest prizes and platform cashback
How it works (FIFO ledger)
Every credit to Saldo Sub is a ledger entry with three fields:
amount— value credited (IDR)remaining— value still available to spendexpired_at— optional expiry timestamp
When you spend, the system deducts from oldest entries first (First-In-First-Out). Expired entries are skipped automatically and cleared by a periodic cleanup process.
Where to see it
App → Profile → Wallet → Saldo Sub. The displayed balance is computed live as SUM(remaining) WHERE expired_at > NOW() — what you see is what you can actually spend right now.
Expiry rules
- Top-up balance never expires.
- Promotional / bonus balance may carry an expiry — always shown in your wallet history.
- Contest prizes typically expire 90 days after credit.
