Custom HubSpot integration development
HubSpot is the CRM platform where your marketing, sales and service come together. But its real power only emerges when HubSpot works seamlessly with your ERP, accounting, e-commerce and other business systems.
We build custom HubSpot integrations that go beyond standard marketplace apps. Bidirectional data flows, custom objects and advanced workflows, tailored to your processes.
What is a HubSpot integration?
A HubSpot integration connects your CRM data with the systems that keep your business running. Contacts, deals, tickets and marketing activities flow automatically to your ERP, accounting software or custom software, and vice versa. No double entry, no outdated data, no manual exports.
Bidirectional sync
Data flows both ways. A new contact in HubSpot appears automatically in your ERP. An invoice status in your accounting system is updated instantly in the HubSpot deal. Always current, everywhere.
Real-time events
Using HubSpot webhooks, your system responds immediately to events: a form submission, a deal moving to a new stage or a ticket being created. No polling, no delay.
Custom objects and properties
Are the standard HubSpot objects not enough? We create custom objects, such as machines, projects, locations or contracts, that are fully searchable and usable in workflows and reports.
HubSpot Hubs we integrate
HubSpot consists of several Hubs, each with its own data and functionality. We build integrations for every Hub, tailored to your specific business processes.
Marketing Hub
Forward form submissions to your back office, sync campaign results with your BI tool, and connect lead scores to your sales system. Keep email lists automatically updated based on data from other systems.
Sales Hub
Synchronise deals with invoicing, generate quotes from CRM data and push pipeline changes automatically to your ERP. Sales reps work in HubSpot while finance sees everything in their own system.
Service Hub
Link tickets to your internal ticketing system, sync SLA data and write customer satisfaction scores back to contact records. Support staff always have the full customer history.
Operations Hub
Data quality automation, programmable workflows and advanced data syncs. Operations Hub is the engine for complex integrations, with custom code actions and webhooks.
CMS Hub
Dynamic website content powered by CRM data. Personalised pages, smart content and HubDB tables that update automatically from your product system or PIM.
Reporting and analytics
Combine HubSpot data with external data sources in custom dashboards. Revenue attribution, campaign ROI and customer lifetime value analyses that go beyond the standard HubSpot reports.

The HubSpot API: technical capabilities
The HubSpot API is extensive and well documented. We use the latest v3 APIs and build integrations that scale, are reliable and stay within rate limits.
REST API v3
Full CRUD operations on contacts, companies, deals, tickets, products and custom objects. Associations API for relationships between objects. Search API with filters, sorting and pagination.
Webhooks and events
Automatic notifications when changes occur in HubSpot. Contact created, deal moved, form submitted — your system receives the event and responds immediately without polling.
Custom code and serverless
Operations Hub custom code actions and serverless functions for complex logic. Data validation, transformations and routing that cannot be achieved with standard HubSpot workflows.
From standalone systems to a connected business operation
HubSpot holds valuable customer data: contact details, interaction history, deal values, support tickets. But if that data stays locked in HubSpot while your ERP, accounting software and internal tools work with their own version of the truth, errors and duplicated work follow. A custom integration makes HubSpot the central hub it should be, connected to every system your business needs.
Why custom instead of a marketplace app?
HubSpot's marketplace offers hundreds of standard integrations. For many businesses, that is enough. But if your processes are more complex, a standard app falls short. That is where custom development comes in.
Specific data flows
You don't want to synchronise all data, only certain fields, under specific conditions, to specific systems. A custom integration gives you control over exactly what flows and when.
Complex business logic
Commission calculations, territory assignment, lead routing based on multiple criteria — logic that doesn't fit standard HubSpot workflows but is essential to your process.
Integrations with legacy systems
Your on-premises ERP, industry-specific software or home-built tools don't have a HubSpot marketplace app. We build the integration that doesn't exist yet.
Volume and performance
Marketplace apps often have limits on the number of records or sync frequency. A custom integration scales with your data and offers real-time synchronisation where needed.
Technology and approach
Our integration specialists build HubSpot integrations using proven technology and a structured approach.
