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.

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?

“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

“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! 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

“We found Avrion very professional, yet friendly and fun to do business with. They really gained our trust.”

Chris Howard – BearingNet

“Working with Avrion has been amazing from start to finish. We use Maximizer as a main system, however we required a bespoke quote tool building for our sales team. From start to finish, the integration of the software and support has been nothing short of phenomenal. Their entire team are very knowledgeable, efficient and nothing is ever too much. We look forward to using Avrion moving forward and continuing a great business relationship.”

Luke Hogg – Knoxford Fabrications

“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

“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

“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

“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

“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

“At our internal review in 2019 we, as a company, asked if we were doing ourselves justice using Maximizer as our CRM solution or was there something better? We concluded that the price point for the system gives us a budget to develop our own specific customisations that are more beneficial for productivity and efficiency as well. 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. 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. Avrion enabled the changes to revolutionise our workflow through small steps that added huge impact. Not many people do that.”
