HubSpot integration: one single version of the customer truth

A HubSpot integration connects the CRM to the company's other applications (ERP, billing tool, e-commerce, telephony, support, business tools) so data flows automatically, with no double entry. A successful integration defines three things before a single line of code: which data flows, in which direction, and which application is the reference for each one.

The simplest option that will hold over time. A native connector from the HubSpot marketplace is enough when the need is standard. An API integration becomes necessary as soon as business rules are specific (custom objects, calculations, conditions). Middleware or an iPaaS platform makes sense when several applications must exchange with each other and flows need monitoring. We choose after mapping the flows, never before.

Yes. It is one of the most common integration projects: bringing customers, orders, invoices or outstanding balances from the ERP into HubSpot so sales and customer service teams work on up-to-date data. At Sprinter, we connected the Odoo ERP, the e-commerce site and HubSpot: sales, billing and stock are visible in the CRM. Most of the work is on the data model and synchronization rules, not on the technical connection itself.

Each piece of data must have a single system of record. In general, the ERP is the reference for financial and logistics data (invoices, orders, payment terms) and HubSpot for relationship and sales data (contacts, interactions, deals). These rules are written in a property-by-property matrix, approved by business teams and the IT department before development.

Yes. Many organizations keep Salesforce or Dynamics for sales and use HubSpot for marketing, or the other way round. The synchronization must then be scoped precisely: synchronized objects, mapped properties, creation and update rules, duplicate handling. Left on default settings, it is the number one cause of degraded databases.

Through three mechanisms: a shared identification key across systems (ERP customer ID, company registration number, email), clear creation rules (which system is allowed to create a record) and error monitoring with alerts. Most synchronization errors come from missing data governance, not from the API.

The project involves the IT department from scoping onward: target architecture, access security, data hosting, documentation and the acceptance testing plan are deliverables in their own right. We work in phases, flow by flow, with business acceptance testing on real cases before each go-live. The goal is that an internal team can understand and maintain the integration years later.

It all depends on the number of flows, the quality of existing data and the availability of APIs in the tools to connect. A well-configured native connector is quick to roll out. An ERP integration with specific business rules runs in several phases. Scoping lets us give a firm schedule, flow by flow.

An integration lives with the information system: new properties, new processes, API updates. We deliver operations documentation and can handle monitoring and changes as part of ongoing support, or hand maintenance over to your internal teams.

An information system map, the target architecture, the data mapping matrix, flow documentation, technical specifications, the testing strategy and operations documentation. These deliverables let the integration evolve without depending on a single person.
