Custom Integrations
and Configuration and Beyond
Make your tools talk. And listen. And automate the heck out of your processes.
We integrate HubSpot with your other systems — CRMs, ERPs, finance tools and more — so your business runs like a single, smart machine.
Our custom HubSpot integrations connect your platforms into a cohesive, automated tech stack that works for you — not the other way around.
Whether you need a simple data sync or an enterprise-grade API solution, we design and build integrations that are secure, scalable, and purpose-built.

Our integration services include:
We design HubSpot integrations that go beyond simple connections — creating intelligent workflows that save time, reduce errors, and improve customer and team experiences.
Bi-directional syncs with Salesforce, NetSuite, and Dynamics — keep CRM data consistent across platforms without manual effort.
Custom middleware for complex business logic — connect CMS, CRM, and fulfilment systems with rules that match your operations.
Real-time data orchestration and reporting — centralise insights with tools like BigQuery or Snowflake.
API integrations and custom UI components — surface delivery updates, purchase history, or ticketing data directly inside HubSpot.
Smart automations — eliminate repetitive tasks and reduce human error.
Scalable, fully documented solutions — built for non-technical users with clear training and long-term support.
If it can be integrated, we've probably done it.
From syncing Salesforce CRM with HubSpot to connecting ecommerce inventory, accounting platforms, or legacy tools, we’ve likely done it. We specialise in both custom and no-code middleware integrations, and we’re not afraid of messy documentation or complex business logic. If the integration doesn’t exist, we’ll build it. If the system is obscure, we’ll make sense of it.
Whether it’s a lightweight sync or a full-blown orchestration engine, we architect solutions that are secure, scalable, and — most importantly — make sense for the people using them.
From no-code middleware to robust custom and enterprise-grade APIs, our team has connected HubSpot to ERPs, CRMs, finance systems, inventory platforms, customer apps, marketing tools, and even a few industry-specific tools you’ve never heard of (and may never want to). If the integration doesn't exist, we build it. If the documentation is terrible, we write it better.
We also build custom HubSpot cards that bring third-party data straight into your records. Think live ticketing info, delivery updates, purchase history, or anything else your team needs at their fingertips — all without switching tabs or platforms.
Use cases include:
Healthcare patient portals with medication reorders and treatment plans
Partner portals for onboarding, resource libraries, and reporting
Investor dashboards with payment history and real-time portfolio data
We had a great experience working with Geff and the team at Engaging.io. From the outset, they approached the project with professionalism, curiosity, and a genuinely collaborative spirit. Their flexible, can-do attitude made it easy to navigate shifting requirements and timelines without friction, and their positive energy helped keep momentum up across the process. Geff in particular brought strong technical insight and creative execution to our design and development work, translating our brief into clean, effective templates and solutions that served both our brand and user needs. The wider team was consistently responsive, proactive, and thoughtful in their communication - always focused on outcomes, never stuck in process. Engaging.io operate with a rare mix of deep capability and grounded pragmatism. They feel like partners, not vendors, and it’s clear they take pride in doing excellent work while being good humans to work with. We’d gladly work with them again.
