Custom Connectors

Secure, scalable connectors that link CRM, finance and specialist platforms into one connected environment.

Not every system integrates neatly.

Many organisations rely on specialist software, legacy platforms or industry-specific tools that do not offer simple, out-of-the-box integration. Standard connectors often fall short, forcing teams to rely on manual workarounds.

Custom Connectors solve this problem.

Avrion designs and builds secure, purpose-built integration layers that connect your systems properly, ensuring data flows reliably and processes remain structured.

When custom connectors are required

Off-the-shelf integration tools are not always sufficient.

Custom connectors become necessary when:

Legacy systems lack modern integration capability
APIs are limited or inconsistent
Data structures differ significantly between platforms
Complex business logic must be preserved
Security or compliance requires controlled architecture
Manual data transfer creates operational risk

In these cases, structured integration architecture is critical.

What custom connectors should deliver

A well-designed connector enables you to:

Synchronise data automatically between systems
Preserve data integrity and validation rules
Trigger workflows across platforms
Maintain clear master data ownership
Reduce manual reconciliation
Improve cross-system reporting

The objective is systems reliability, not simply connectivity.

Types of systems we commonly connect

Custom connectors are frequently built between:

CRM platforms and finance systems
ERP and operational software
Industry-specific databases
Marketing automation tools
Bespoke web and mobile applications
Reporting and data platforms

Each connector is designed around specific business requirements rather than generic assumptions.

Automation and workflow integration

Custom connectors often enable:

Automated order-to-invoice processes
Real-time data synchronisation
Cross-system approval workflows
Customer status updates
Performance reporting alignment

Integration becomes a driver of operational efficiency.

Security, governance and monitoring

Integration must be properly controlled.

We ensure:

Secure authentication and encryption
Role-based access management
Structured error handling
Logging and performance monitoring
Clear ownership and lifecycle planning

Protecting both data integrity and systems performance.

The Avrion approach to custom integration

We approach connector development architecturally.

Our methodology includes:

Mapping systems architecture and dependencies
Defining data ownership and synchronisation logic
Designing secure API or middleware connections
Implementing validation, logging and error handling
Documenting integration logic
Establishing governance and monitoring processes

This ensures integrations remain maintainable, lawful and scalable.

Relying on manual data transfers?

If teams export and import spreadsheets between systems regularly, or data inconsistencies create reporting challenges, a Business Health Check can identify where custom connectors would deliver measurable improvement.

We assess:

Current integration gaps
Data duplication and accuracy risks
Workflow inefficiencies
Scalability concerns

Providing structured recommendations mapped to your commercial priorities.

Planning a custom integration project?

A structured discovery conversation ensures your integration architecture supports long-term growth.

We help you:

Refine integration requirements clearly
Reduce operational complexity
Strengthen reporting reliability
Build scalable digital infrastructure

What do our customers say?

“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

“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

“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

“Avrion is an agile, approachable, friendly company. They are easy to deal with and deliver on what they set out to achieve.”

Tom Crowther – Belvoir

“Avrion has, from the start, been very honest and clear about what we can achieve without spending vast sums of money on an entirely new system. We now have a system that can evolve as the development does, to improve and continually improve account visibility for our homeowners and improve cash flow by utilising the automation that we required.”

Carly Cullen – Priors Hall Park Management

“Integrating over 30 acquisitions, meant harmonising over 60 customer databases. Impressive, but of little use if the data is unstructured. Maximizer meant structured data, yes it requires focus, but the output is efficient to say the least; the new improved pipeline made us twice as effective, cross selling across the 5 business units - closure went up 4-fold. Integrating this with front line operational calls gave us a holistic view, reducing hundreds of days spent on internal calls, joining up the dots for our customers. Opportunities grew by over 20% with straightforward data polishing. The icing on the cake was with GDPR, good process with opt-outs and customer choice on contact options. When you feed this into the business it allows us to be focussed on the day-to-day operation, the back-end processes of store, scan and shred just become slicker – our focus with customers substantially better. Hundreds of hours freed up for improvements on invoicing, value added services, the day to day delivery with document management”

David English – Restore plc

“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 can now see in real time how all of our opportunities are progressing. We also have automated reports in our Dashboard module showing the business sales performance and pipeline, which allows us to focus on each individual opportunity without any being left unnurtured. Avrion has now linked our Maximizer with Mailchimp to allow for focused marketing campaigns based on the data we add to the Address Book. We now have a clear sales process that can be tracked with clear ‘what’s next’ actions to implement.”

Craig Sansom – Prestige

“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

“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.”
