Enterprise platforms designed for scale, integration and audit.
BitAzure builds SaaS products, ERP and CRM systems, financial platforms and automation for organisations that need multi-tenant architecture, single sign-on, role-based access, audit logging and clean integration with the legacy systems already running the business.
- SaaS, ERP, CRM and financial systems
- Microservices, APIs and event-driven integration
- SSO, RBAC, audit logging and multi-tenancy
- Data platforms, reporting and enterprise dashboards
What is enterprise software development?
Enterprise software development is the design and delivery of applications that run core business processes for organisations: customer, finance, operations and workflow systems that must integrate with existing platforms, enforce access control, preserve an audit trail and keep working as users, data and regulations grow. It includes product engineering, systems integration, data platforms and the cloud infrastructure underneath.
BitAzure delivers enterprise software as custom SaaS platforms, ERP and CRM systems, financial back offices, business automation and data products. Engagements typically start with an integration and domain model, then deliver microservices behind an API gateway, an event bus for asynchronous processes, a data platform for reporting and the identity, tenancy and audit controls that enterprise buyers expect.
Our background in financial and blockchain systems shapes how we build: ledgers are double-entry, actions are attributable, permissions are explicit and integrations are resilient to the failures of the systems on the other side.

- Coexistence strategies during phased cutover
Reference enterprise platform architecture
Clients reach domain services through a gateway and backend-for-frontend, services publish events to a bus that feeds the data platform and integrations, and observability covers every hop.
Hover or focus a component to see its role in the architecture.
- Web Clients (React · admin & portals): Internal consoles, customer portals and partner interfaces built on a shared design system.
- Mobile Clients (React Native): Field and approval apps sharing TypeScript logic with the web clients.
- API Gateway / BFF (Auth · routing · aggregation): Validates SSO tokens, resolves tenant context, enforces RBAC and aggregates service calls per client.
- Observability (Metrics · logs · traces): Centralised telemetry with tenant-aware dashboards and alerting across every service.
- Identity Service (SSO · RBAC · tenants): Federation with SAML and OpenID Connect providers, role and permission management, tenant directory.
- Billing & Ledger (Subscriptions · invoices): Double-entry ledger, subscription lifecycle, invoicing and reconciliation with payment providers.
- Workflow & Reporting (Cases · approvals · reports): Configurable workflows with SLAs and escalations, plus scheduled and ad-hoc reporting.
- Event Bus (Kafka): Durable domain events consumed by the data platform, integrations and asynchronous processes.
- Data Platform (Warehouse · lake): Governed models for dashboards, regulatory reports and embedded analytics with row-level security.
- Integrations (ERP · CRM · banks): Adapters with retries, idempotency and reconciliation for legacy and third-party systems.

Enterprise systems we build
Vertical SaaS products
Multi-tenant platforms for a specific industry with billing, onboarding and admin built in.
Financial back offices
Ledgers, reconciliation, settlement and reporting for payment, lending and treasury operations.
ERP replacement or extension
Custom modules where packaged ERP does not fit, integrated with the modules that stay.
CRM and customer operations
Pipelines, case management and customer 360 views built on your data model.
Operational automation
Approval chains, onboarding and compliance workflows replacing spreadsheets and email.
Data and reporting platforms
Warehouses, dashboards and regulatory reports fed by every system in the estate.
Why organisations build enterprise software with BitAzure
Domain modelling first
Entities, ownership and lifecycle are agreed before code, so services map to how the business actually works.
Integration resilience
Retries, idempotency and reconciliation protect the platform from failures in legacy and third-party systems.
Enterprise controls built in
SSO, RBAC, audit logs and tenant isolation are part of the foundation, not a later hardening phase.
Financial-grade data handling
Double-entry ledgers, immutable audit trails and reconciliation practices from our fintech work apply to every system.
Scalable by design
Stateless services, event-driven processing and a data platform that grows with users and tenants.
Clear ownership and handover
Source, infrastructure code, runbooks and documentation delivered so internal teams can operate the platform.

How we deliver enterprise platforms
Every engagement follows a documented, milestone-driven path from discovery to continuous development.
- 01
Discovery and domain modelling
Processes, systems, data ownership and compliance obligations are mapped into a domain model and integration inventory.
- 02
Architecture and tenancy design
Service boundaries, tenancy model, identity, event schemas and data platform design are documented and reviewed.
- 03
Foundation build
Gateway, identity, audit logging, CI/CD and observability are delivered first so every feature inherits them.
- 04
Domain services and interfaces
Services, workflows, dashboards and portals are delivered in prioritised increments with automated tests.
- 05
Integration and migration
Adapters to legacy and third-party systems, data migration with reconciliation and phased cutover planning.
- 06
Operations and evolution
Production support, performance tuning and a roadmap for new modules, tenants and integrations.
Security practices in enterprise software
Identity and access
SSO federation, MFA enforcement, RBAC with least privilege and periodic access reviews.
Tenant isolation
Row-level or schema-level isolation with tenant context enforced in every query and event.
Audit logging
Immutable, searchable logs of user and system actions with retention aligned to policy.
Data protection
Encryption at rest and in transit, secrets management and field-level encryption for sensitive data.
Secure SDLC
Code review, dependency scanning, static analysis and penetration-test coordination before major releases.
Audit preparation
Controls, evidence collection and documentation designed to support SOC 2 or ISO 27001 readiness programmes.
We coordinate independent third-party audits on request and never claim an audit, certification or compliance status unless it has actually been obtained.
What to decide before an enterprise build
Build versus configure
Packaged ERP or CRM may cover most needs; custom software is justified where differentiation, integration or scale demands it.
Tenancy model
Shared schema, schema-per-tenant and database-per-tenant differ in isolation, cost and operational complexity.
Integration ownership
Legacy systems change on their own schedule. Define contracts, monitoring and ownership for every integration.
Data governance
Decide the system of record for each entity early; conflicting sources cause the most expensive bugs.
Change management
Enterprise rollouts depend on training, migration windows and coexistence with old systems as much as on code.
Compliance scope
Frameworks such as SOC 2 or ISO 27001 shape logging, access and vendor requirements; plan for them during architecture rather than before an audit.
Enterprise Software questions
Both. We build custom modules where packaged software does not fit and integrate with existing ERP, CRM and core systems through APIs, files or message queues. The choice is made per capability during discovery.
