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?

“Once we formed a partnership with Avrion, for the first time in seventeen years we were working with a really engaged partner, which is something unique.”

Cole Fellows – The Insurance Network

“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

“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

“With our workload and team outgrowing our old method of workflow management, we needed a solution. Having worked with Avrion in the past, we asked them to take a look. Dave, Nick and Sam took the time to go through our process with us. It was decided that a ticketing system was required - the guys set up what we required and assisted us whilst we inputted our data and got it going. I think the level of customer service we have received from Avrion is 5 stars.”

Mike Bevan – SPM Instrument UK

“After a feasibility study designed to ascertain which CRM to integrate into our business, I found that Avrion put together the best end scenario and product, Maximizer, to take our business forward. The team at Avrion showed their diligence and knowledge, which was a clear deciding factor in instigating our partnership. We look forward to strengthening our relationship going forward, as CRM evolution never stops!”

Craig Sansom – Prestige

“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

““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

“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 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

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

Tracey Hammond – Dengie
