Integrate legacy, industry-specific and bespoke systems with your Maximizer ecosystem securely and at scale.

Most organisations operate more than just a CRM and finance platform.

You may rely on legacy databases, specialist industry software, internally developed tools or operational systems that are critical to daily performance. When these systems operate in isolation, visibility suffers and manual work increases.

Custom Systems Integrations connect Maximizer to the wider technology environment, ensuring data flows reliably and consistently across your organisation.

Avrion designs integration architecture that supports long-term stability, not fragile connections that don’t.

Why custom integration requires structure

What effective custom integration should deliver

A well-designed custom integration enables you to:

  • Connect legacy systems to Maximizer
  • Synchronise critical operational data
  • Reduce manual rekeying and reconciliation
  • Improve cross-department visibility
  • Support automation and reporting
  • Scale without repeated redevelopment

The goal is connections, resilience and clarity.

The Avrion approach to Custom integration

We approach custom integration strategically.

Our methodology includes:

  • Reviewing your current systems architecture
  • Mapping data flows, ownership and permissions
  • Designing secure API or middleware-based connections
  • Implementing validation and monitoring
  • Establishing documentation and governance
  • Planning for future upgrades and system changes

This ensures integration supports growth rather than limiting it.

Integration technologies and architecture

Depending on your environment, we may use:

  • Structured API integrations
  • Middleware and integration layers
  • Event-driven workflows
  • Secure data synchronisation models
  • Automation tools aligned to your CRM configuration

Each integration is designed around performance, security and maintainability.

Security, governance and monitoring

Custom integrations must be controlled.

We ensure:

  • Secure authentication and encryption
  • Role-based access controls
  • Logging and monitoring for performance
  • Clear ownership and lifecycle management
  • Structured documentation for ongoing support

Protecting both operational continuity and data integrity.

Operating in a complex or legacy environment?

If key systems are disconnected, manual processes are compensating for technical gaps or if reporting requires reconciliation across platforms, a Business Health Check can clarify your integration priorities.

We assess:

  • Existing architecture and data flow
  • Manual workarounds and duplication
  • Risk exposure and bottlenecks
  • Opportunities for simplification

Providing commercially focused recommendations.

What do our customers say?

“We have experienced a huge shift in the efficiency of the business with the all-round delivery of service.”

Tracey Hammond – Dengie

“We found the team at Avrion really understood our needs. It felt like they’d seen it all before, and that gave us confidence from day one. With Maximizer CRM, what it really does is allow us to track that from start to result stage… it’s helped change the mentality of our business.”

Chris Harrison – Heidelberg Materials Contracting

“After almost a year of trying unsuccessfully to engage with our existing partner, trying to get them to talk about upgrading and personalising the system, we decided to switch over to Avrion. Avrion had been in conversation with us and once we engaged with them, they immediately gave us something unique. They allowed us to effectively have an off-the-shelf CRM system that we could customise – at affordable rates. Rates that are competitive for SMEs.”

Cole Fellows – The Insurance Network

“We created an automation wish list for Avrion, who were brilliant at listening and communicating as they tailored the project specifically to the scope.”

Carly Cullen – Priors Hall Park Management

““The reason why I like working with Jon is because he always comes up with a solution. This was a small project but it has a big impact and solves lots of time problems. I can now make updates to the communications that go out myself and don’t need the support of Avrion for this going forward, although they are always on hand if I need help.””

Jane Margetts – Restore Records Management

“We were looking for best service provider for our CRM system and we came across with Avrion in 2016 and since then we have never turned back in terms of CRM system. This was our best step to move with Avrion as they understood our requirement quickly with excellent solutions and also within our budget. Working with Avrion is wonderful experience; we never need to approach them for any issues as they are always one step ahead by taking regular follow-ups. They are quick and punctual in terms of completing project. We have undertaken many projects so far and are more than happy to say that their solution is up to the mark. Avrion's people are the greatest asset of the company. I really recommend Avrion not only CRM system but for many other IT solutions as well.”

Satish Ghaghada – CWC

“Data is one of the most valuable assets any business has, but unlocking its true value depends on quality, meaningful analysis, and having the right tools and skills to turn insights into strategy and revenue. Having worked with Avrion, I can say they really do bring the expertise to help businesses make that transformation!”

Catherine Royle – Restore plc

“Our project involved coupling existing platforms with new CRM technologies, training and a complex project roll-out. Avrion managed the transition without fuss or any ‘catch-you’ extra fees – a job well done.”

David English – Restore plc

“I’m using Power BI a lot more now than I did when we started with creating refreshable dashboards for the Senior Leadership Team and other management levels showing different elements of the business. We are doing this by implementing the data warehouse built by Avrion, which is very handy. I love Power BI and think it is such a great tool that every business can have/use as it turns your raw data into a story that shows different aspects from the company over time.”

Dan Costin – Restore Datashred

“Maximizer CRM has been an invaluable tool. It enables us to be very efficient, keep on top of client projects and opportunities, and deliver the service we want to for our customers.”
