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?

“Avrion built the system according to our needs and fine-tuned it as required once we began to use it. They have been very supportive throughout and helped us navigate through the entire process.”

Carly Cullen – Priors Hall Park Management

“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

“I'd 100% recommend Avrion. It's been a dream working with them. They have helped us at every point in this process. I've worked with people in the past where there's a bit of tension, but with Avrion they always helped to direct our journey, in a way that was working with us as a partner, over anything else.”

Jasmin Dudden – Restore Datashred

“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

“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

“We first came across Maximizer Sales Leader Edition (SLE) when looking for a CRM system with quoting functionality to replace an aged manual system based mainly on Excel! From development to implementation, each stage was found easy to transact and made easy to understand with the support offered found to be exceptional. Our main area of focus was to improve systems to reduce stress on resource with minimal impact on the team – this was achieved with great success & the system welcomed.”

Liane Atherton – AAF Air Filters

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

Tracey Hammond – Dengie

““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

“Connolly's Red Mills have been working with Avrion since 2017 with our Maximizer implementation and have found them to be a great company to deal with, projects completed in a timely manner to a high standard.”

David Dewberry – Connolly’s Red Mills

“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
