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?
“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“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“After almost a year of trying unsuccessfully to engage with our existing partner, trying to get them to talk about upgrading and personalising the system, we decided to switch over to Avrion. Avrion had been in conversation with us and once we engaged with them, they immediately gave us something unique. They allowed us to effectively have an off-the-shelf CRM system that we could customise – at affordable rates. Rates that are competitive for SMEs.”
Cole Fellows – The Insurance Network“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 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“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““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“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“Avrion is an agile, approachable, friendly company. They are easy to deal with and deliver on what they set out to achieve.”
