New guideModernizing a legacy system without stopping the business

Eryon AI Software Solutions

B2B / Enterprise

Core systems for B2B companies and enterprise operations.

B2B companies run on long relationships, complex pricing, multiple sites and many internal teams. Their core systems need to be dependable, integrated and adaptable over years.

The Industry Challenge

Core processes are split across legacy systems, packaged tools and spreadsheets that don't share data.

The operational problem

  1. 01Multiple sites or business units report differently.
  2. 02Legacy systems block integration with newer tools.
  3. 03Partner and customer requests are handled by email.
  4. 04Workforce, project and billing data don't reconcile.

The Digital Solution

ERPs, partner portals and integration layers that give each business unit the tools it needs and leadership one consistent view — modernized in stages rather than replaced in a single risky project.

Systems Required

What the software stack usually includes.

01

Enterprise resource planning

Projects, workforce, materials and billing.

02

Partner and customer portals

Orders, requests and documents.

03

Integration layers

APIs and events connecting existing systems.

04

Executive reporting

Consolidated operational and financial views.

Who We Build For

B2B / Enterprise segments we understand.

  • Construction and infrastructure

    Attendance, wages and client bills are reconciled monthly by hand.
    What we build
    Construction ERP with role-based portals, payroll support and automated ledgers.

  • Industrial suppliers

    The problem
    Customer-specific pricing and orders are handled by email.
    What we build
    B2B ordering portals with account pricing and approvals.

  • Multi-unit enterprises

    The problem
    Business units report in different formats.
    What we build
    Shared data models and consolidated executive reporting.

  • Companies on legacy systems

    The problem
    Old software blocks integration with new tools.
    What we build
    API layers and staged modernization without big-bang cutovers.

  • Field-heavy operations

    The problem
    Site and field data arrives late and on paper.
    What we build
    Mobile field apps feeding the central system in real time.

Where To Start

What we'd build first.

Pick the process that crosses the most teams — often projects and billing, or orders and inventory — and build a system of record for it with APIs from the start. Other modules and legacy integrations follow in stages.

Typical Workflows

The work the system has to support.

  1. STEP 1Project setup and tracking
  2. STEP 2Attendance and payroll
  3. STEP 3Procurement and materials
  4. STEP 4Client billing and ledgers
  5. STEP 5Cross-unit reporting

Security & Compliance

Considerations we design for.

We build software that supports your compliance obligations. We are not a certification body; formal compliance remains with your organisation and its advisers.

  • Segregation of duties in approval workflows
  • Single sign-on and centralised access control
  • Audit trails across modules
  • Data residency options on major cloud providers

FAQs

B2B / Enterprise software questions.

What is enterprise software development?

Designing and building systems that run core business processes across many teams — ERP, portals, integrations and reporting — with the security and reliability that daily operational use requires.

Can you work alongside our existing IT team?

Yes. We can deliver whole modules or work as an extended engineering team within your processes.

Do you support single sign-on?

Yes, with your identity provider through standard protocols.

How do you integrate with legacy systems?

Through APIs, database integration or scheduled exchange, chosen after reviewing what the legacy system can safely support.

Can the system be hosted in our own cloud account?

Yes. Infrastructure is provisioned in your AWS, Azure or Google Cloud account and managed as code.
