Architecture
A reference enterprise architecture for BillXPro as a revenue control layer: system boundaries, integration posture, data flows,
deployment options, and non-functional design principles.
providing an orchestration and control layer for revenue workflows without forcing disruptive replacement programs.
Reference Architecture Overview
The reference architecture is structured around a layered approach with clear system boundaries, controlled interfaces,
and enterprise-ready governance.
Layered Model
- Experience Layer: admin console, finance workbench, customer portal
- Revenue Orchestration Layer: billing logic, invoicing, subscriptions, collections workflows
- Controls Layer: approvals, maker-checker, audit trails, RBAC, entity boundaries
- Integration Layer: API gateway, webhooks/events, batch exports, adapters
- Data & Evidence Layer: transactional store, logs, reporting store, audit evidence outputs
Boundary Principles
- ERP remains system-of-record for accounting and GL posting (unless otherwise agreed)
- BillXPro owns revenue workflow: invoice, billing schedules, collections orchestration
- Acquiring remains external: BillXPro aligns to acquiring APIs, settlement and reconciliation flows
- Identity & access: can align with enterprise SSO policies where required
- Auditability: every sensitive action can be traced to user/role/time/context
Enterprise System Interaction Map
Typical integration posture across enterprise systems. Exact integration scope is aligned during design workshops.
Upstream Systems
- ERP/Finance: chart of accounts mapping, invoice posting references
- CRM/Contracts: customers, plans, schedules, entitlement triggers
- Master Data: entity/branch structure, segments, tax identifiers
BillXPro Core
- Billing rules & schedules
- Invoice generation & control
- Collections workflows
- Approvals, RBAC, audit trails
- Reporting and intelligence
Downstream Systems
- Acquiring/PSP: payment execution, settlement references
- Messaging: email/SMS/WhatsApp (approved channels)
- BI/Analytics: exports, dashboards, reporting feeds
End-to-End Data Flow (Reference)
A typical invoice-to-cash flow illustrating how BillXPro preserves traceability from billing policy to collection and reconciliation.
Invoice-to-Cash Flow
- Billing event triggered (schedule/on-demand/policy event)
- Invoice generated with entity template, tax policy, line-item structure
- Approval checks (if required) before release
- Payment journey created (link/portal/reminder plan)
- Customer pays via approved channels aligned to acquiring infrastructure
- Receipt issued and invoice status updated with settlement references
- Reconciliation outputs prepared for finance and operations
Traceability Guarantees
- Invoice ↔ billing policy ↔ schedule / event linkage
- Payment link ↔ invoice reference mapping
- Payment logs ↔ acquiring settlement reference tracking
- Controlled lifecycle events: credit notes, cancellations, refunds
- Audit trails: who changed what, when, and under which approval
Exact reconciliation model depends on acquiring outputs, settlement schedules, and enterprise finance operating standards.
Deployment & Topology Options
Deployment approach is aligned to enterprise security posture, data residency, and operational governance requirements.
Single-Tenant Enterprise
Dedicated platform deployment for one enterprise group, supporting multi-entity operations with isolated governance boundaries.
- Entity/branch segregation
- Dedicated encryption boundaries
- Enterprise SSO alignment (where required)
Multi-Entity Program
Structured topology for group-level governance with multiple operating entities and controlled rollout sequencing.
- Group governance + entity autonomy
- Central policy model with localized templates
- Consolidated reporting with drill-down
Partner / Bank Enablement
Enablement aligned to institutional governance models where revenue flows span multiple merchants, segments, or programs.
- Strict role separation
- Audit-first operational model
- Alignment with acquiring infrastructure
Enterprise Non-Functional Posture
Non-functional design is a key evaluation criterion for enterprise environments. The posture below reflects typical requirements;
exact targets are finalized per engagement.
Scalability & Availability
- Horizontal scalability for transaction peaks
- Separation of workload domains (billing, reporting, messaging)
- Controlled degradation for non-critical services
- High-availability design aligned to hosting standards
Observability & Operability
- Operational dashboards and system health visibility
- Audit logs for configuration and critical actions
- Traceability across billing → invoice → payment → settlement
- Structured exports for enterprise monitoring/BI needs
Security Baseline (Summary)
- Role-based access control and entity boundaries
- Approval workflows for sensitive actions
- Encryption-in-transit and standard secure storage controls
- Secure integration patterns and controlled interfaces
For detailed controls, review the Security & Governance page.
Data Governance
- Defined data ownership boundaries across systems
- Evidence and audit artifacts for compliance review
- Configurable retention policies (as per agreement)
- Structured exports and controlled reporting access
Implementation Blueprint (Reference)
A structured approach aligned to enterprise delivery expectations — discovery, architecture alignment, phased rollout, and controlled enablement.
Step 1 — Architecture Alignment
Confirm system boundaries, integration patterns, identity alignment, and deployment topology.
Step 2 — Controlled Enablement
Configure entities, governance, policies, templates, and billing/invoicing lifecycles.
Step 3 — Integration & Rollout
Implement ERP/CRM/acquiring integration, validate data flows, then expand entity-by-entity.
