- Integer minor units
- All money is integers in minor units. No floating-point drift, ever — the ledger that reconciles to the centavo is a design decision, not an aspiration.
- Fund allocation at capture
- Fee rules from the Government Pack split every payment across funds (judiciary development funds, special education funds, general fund) at the moment of capture — not in a year-end spreadsheet.
- OR series integrity
- Official-receipt numbers issue from monitored series with gap detection. A missing OR number is an alert, not a mystery.
- Gateway adapters
- Cards, mobile wallets, bank transfers, and regional payment rails plug in as adapters; over-the-counter cashiering is first-class for the counters that will exist for decades.
- Reconciliation
- Daily three-way reconciliation: system ledger, gateway settlement, and bank statement. Variances surface as work items with owners, not as footnotes.
- Refunds & adjustments
- Refunds, over-payments, and adjustments follow audited workflows with approval chains — the corrections are as traceable as the payments.
