Provider registry
Maintain explicit provider capabilities, environment status and operational controls without binding business logic to a single external provider.
PLATFORM
A financial control layer between your products and payment providers.
Nexus combines provider orchestration, double-entry ledgering, internal value movement, reconciliation and settlement controls in one platform-neutral architecture.
Payment intents
Create controlled lifecycle records before any external call, retaining idempotency, source attribution and provider references.
Request and webhook audit
Preserve provider requests, responses and webhooks for investigation, reconciliation and dispute handling.
LEDGER CORE
The ledger remains the financial authority.
Balances are not treated as mutable counters. Nexus records economic events through double-entry transactions and keeps audit data around every posting.
- Double-entry ledger transactions and entries
- System accounts for clearing and operational positions
- Controlled posting lifecycle
- Provider-aware idempotency and external references
- Immutable audit trail for financial actions

RECONCILIATION & SETTLEMENT
Provider confirmation is not the end of the workflow.
Nexus compares external provider activity against the internal ledger, surfaces mismatches and requires controlled settlement states before economic positions are treated as final.

ADDITIVE ARCHITECTURE
Provider rails can evolve without rewriting the core.
Card processors, bank rails and digital-asset providers live behind adapters. The account, ledger and operator model remains stable as providers are added or replaced.
