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?
“We have experienced a huge shift in the efficiency of the business with the all-round delivery of service.”
Tracey Hammond – Dengie“Working with Avrion has been easy – not just because they understand the business, but because they are open to helping make things work. The answer is almost never “no” – but if it is – there is always an alternative solution to get around the issue put forward.”
Charlotte Hurrell – Belvoir Group“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.”
Raj Mahay – Resin Products“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“Avrion’s AI and automation solution transformed our operations. What used to take three full-time staff days to process now happens automatically - accurately, consistently, and at scale. We’ve reclaimed time, reduced errors, and empowered our team to focus on higher-value work. It’s been transformative.”
COO at a leading UK waste management company“Avrion is able to grasp a concept quickly and turn it into a deliverable that can make a significant difference to a business. They take the time to understand the requirement, taking concepts and ideas and turning them into tangible benefits to achieve the best outcome possible for the customer.”
Jasmin Dudden – 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.”
Graham Cording – Smart Presentations“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““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“Avrion is an agile, approachable, friendly company. They are easy to deal with and deliver on what they set out to achieve.”
