Custom Connectors
Purpose built integrations designed around your systems
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.

What do our customers say?
“Avrion truly understood our business and tailored Dynamics 365 to fit our needs. The phased approach made adoption seamless, and we’re already seeing major time savings. Our internal processes are now streamlined, and we’re well-positioned for future growth. It’s a game-changer for us. Looking back, partnering with Avrion to implement Microsoft Dynamics 365 was one of the best decisions we made. Our operations are now efficient, our team collaborates seamlessly, and we’re equipped to scale our business with confidence. If your company is struggling with inefficiencies like we were, I highly recommend working with Avrion – they’ll make sure you get a solution that truly works for you.”
Raj Mahay – Resin Products“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. 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“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“We found Avrion very professional, yet friendly and fun to do business with. They really gained our trust.”
Chris Howard – BearingNet“We would highly recommend Avrion for both CRM and tech support applications. We recently upgraded our tech support function for both internal and external support requests. This has improved our response times, planning, service level agreements and overview of the department. Avrion is always ready to suggest improvements and evolution for our business. A big thanks to Dave, Nick and Sam at Avrion for their work on this project.”
James Blair – SPM Instrument UK“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 created an automation wish list for Avrion, who were brilliant at listening and communicating as they tailored the project specifically to the scope. 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. 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“Before Dynamics 365, we were managing tours through a mix of spreadsheets, emails and manual processes. Now, everything is in one place and works together seamlessly. The system is built around how we operate, not the other way around, and automates tasks that used to take hours. Most importantly, it gives us the flexibility to manage any type of tour and confidently support our continued growth.”
Karen Leggatt – Classic Grand Touring“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 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.””
