HubSpot Business Central Integration: How to Connect CRM and ERP
HubSpot and Microsoft Dynamics 365 Business Central often serve different but closely connected parts of the same business.
HubSpot typically supports marketing, sales and customer relationship processes, while Business Central manages areas such as finance, orders and other operational processes. Both platforms can work effectively on their own. The challenge appears when a business process needs to move from one to the other.
A salesperson might close a deal in HubSpot, for example, while Finance needs the relevant customer and commercial information in Business Central. Later, Sales may need information about the customer's orders or financial status without having to switch systems or ask another department.
Without integration, these handovers often depend on manual data entry, spreadsheets or communication between teams. As we explored in our article on CRM and ERP integration: the hidden costs of disconnected systems, those gaps can create duplicate work, inconsistent information and limited visibility across the customer lifecycle.
A well-designed HubSpot Business Central integration addresses this by allowing relevant information to move between CRM and ERP while keeping each platform focused on the processes it is designed to manage.
But connecting the platforms is only part of the challenge. The more important question is what should be integrated, in which direction, and for what business purpose?
1. What Does HubSpot Business Central Integration Actually Mean?
There is already a native way to connect the two platforms.
HubSpot provides a certified Microsoft Business Central Data Sync app, built by HubSpot, for synchronizing data between Business Central and HubSpot. According to HubSpot's Marketplace listing, the integration supports two-way synchronization, default field mappings and historical synchronization, allowing existing information to be synchronized alongside subsequent updates.
Microsoft also lists the HubSpot integration in its own Marketplace and describes the same two-way, real-time synchronization capabilities.
For organizations with relatively straightforward synchronization requirements, this provides a logical starting point.
However, installing a connector and integrating a business process are not necessarily the same thing.
The native integration has its own supported data model and configuration requirements. HubSpot's current Marketplace documentation, for example, specifically notes that Business Central customers currently synchronize with HubSpot contacts rather than companies. Custom field mappings also depend on the appropriate HubSpot Data Hub subscription.
That distinction becomes important for B2B organizations whose CRM processes are heavily structured around companies, or businesses that need information and workflows beyond the standard synchronization model.
2. What Should You Integrate Between HubSpot and Business Central?
One of the easiest mistakes in an integration project is starting with a list of fields.
A better starting point is the business process.
Consider a simplified customer journey:
Lead → Opportunity → Customer → Order → Invoice → Ongoing relationship
HubSpot and Business Central participate in different parts of this journey. The purpose of integration is to make sure that information can cross the boundary between those systems when employees or downstream processes need it.
HubSpot might contain customer relationships, sales activities, pipeline information and marketing engagement. Business Central may contain customer financial records, items, sales orders, invoices and other operational information.
That does not mean all of this information should be duplicated between both systems.
Define the system of record first
Before deciding what should synchronize, determine which platform owns each type of information.
For example, an organization might decide that HubSpot is authoritative for sales pipeline information while Business Central remains authoritative for invoices and financial information.
Other information may need to move in both directions.
There is no universal mapping that works for every organization. Customer structures, product models, sales processes and Business Central configurations can vary significantly.
What matters is establishing clear ownership before synchronization begins.
Otherwise, two-way synchronization can introduce another problem: if the same information can be independently changed in both systems, which version should the business trust?
This is also why CRM data quality is fundamental to business growth. Integrating two platforms does not automatically resolve duplicate records, inconsistent identifiers or poorly structured customer data. Without clear data governance, integration can simply distribute those problems across more systems.
Integrate for context, not duplication
The same principle applies to how much ERP information should become available inside HubSpot.
Sales teams may benefit from seeing relevant operational or financial context when working with a customer. But that does not necessarily mean reproducing the entire Business Central environment inside the CRM.
The goal should be to identify the information employees need to make decisions and complete their work.
A salesperson might need relevant order or customer information. Finance may need accurate commercial information when a sales process reaches a certain point.
Management may need information from both platforms for reporting.
Detailed ERP processes can still remain where they belong: inside Business Central.
Good integration gives each team the context it needs without unnecessarily duplicating the systems themselves.
3. Native Data Sync vs. a More Advanced HubSpot Business Central Integration
Not every HubSpot Business Central integration requires custom engineering.
If an organization's requirements align with HubSpot's supported Data Sync functionality, the native integration may provide an appropriate solution. HubSpot provides default mappings and allows existing records and subsequent changes to be synchronized between supported objects.
The complexity increases when the business requirement extends beyond standard record synchronization.
For example, an organization may want integration to:
respond to specific events in the sales process;
transform information before it reaches Business Central;
work with a customized Business Central environment;
apply complex matching or validation rules;
coordinate multiple actions across the CRM and ERP;
make additional ERP information available to HubSpot users;
connect HubSpot and Business Central with other applications in the wider technology stack.
At this point, the requirement starts moving from data synchronization toward business-process integration.
Depending on the architecture, this can involve APIs, an integration platform, middleware or custom development. The appropriate approach depends on the complexity of the process and the systems involved.
This is why we recommend starting with the desired workflow rather than selecting the integration technology first.
A standard connector may be entirely sufficient for one organization. Another organization using the same HubSpot and Business Central products may require a significantly different architecture because its customer data model, sales process or ERP environment is different.
The objective should be to use the simplest architecture that reliably supports the required business process, rather than adding technical complexity unnecessarily.
4. What Can HubSpot and Business Central Integration Look Like in Practice?
The value becomes easier to understand when we look at the integration from the perspective of a business process rather than individual fields.
Consider a company where Sales works primarily in HubSpot while Finance and Operations work primarily in Business Central.
A potential workflow could look like this:
1. Sales manages the opportunity in HubSpot
Customer communication, activities and the commercial opportunity are managed within the CRM.
2. The opportunity reaches an agreed point in the sales process
This could create the business requirement for relevant information to move toward the ERP environment.
3. Customer and commercial information becomes available to Business Central
Instead of someone manually copying information from the CRM, the integration can support the handover between the two environments.
4. Finance and Operations continue their processes in Business Central
Business Central remains responsible for the relevant ERP processes rather than trying to reproduce them inside HubSpot.
5. Relevant ERP context can be made available to customer-facing teams
Depending on the integration architecture, appropriate Business Central information can flow back toward HubSpot, giving users additional context without requiring them to work directly inside the ERP.
The exact records, triggers and automation involved will depend on the integration method and configuration. This example should therefore not be interpreted as functionality automatically provided by HubSpot's native Data Sync connector.
Instead, it illustrates the broader objective: connecting the commercial and operational stages of the customer lifecycle.
The result is not simply synchronized databases. It is a more connected process between Sales, Finance and Operations.
For a broader look at why these connections matter, our article on CRM and ERP integration explores the operational costs that emerge when customer and back-office systems remain disconnected.
5. How Should You Approach a HubSpot Business Central Integration?
The technology should come after the process design.
Before implementing a HubSpot Business Central integration, we recommend answering several fundamental questions.
Which business processes cross the two systems? Identify where information currently needs to be manually transferred between HubSpot and Business Central.
Which system owns each type of data? Define where customer, commercial, product, order and financial information should be maintained.
What information actually needs to move? Avoid synchronizing information simply because it is technically possible.
In which direction should information move? Some data may need one-way synchronization, while other information may genuinely require updates in both systems.
How will records be matched? Reliable identifiers and matching logic are essential for preventing duplicate or incorrectly associated records.
What should trigger the integration? A field update, record creation or change in a business process may require different integration behaviour.
What happens when something fails? Error handling, monitoring and ownership need to be considered from the beginning rather than after synchronization problems occur.
What will the business need next? The integration should account for future reporting, automation and AI requirements rather than solving only today's immediate synchronization problem.
That final consideration is becoming increasingly important.
As we discussed in HubSpot AI Features Every Sales Team Should Know, AI is becoming increasingly embedded in CRM workflows. But useful AI depends heavily on the quality and context of the information available to it.
Connecting CRM and ERP does not automatically make a company "AI-ready." It can, however, create a stronger data and process foundation by making relevant commercial and operational information available across previously disconnected environments.
A successful HubSpot Business Central integration therefore should not attempt to turn HubSpot into an ERP or Business Central into a CRM.
It should allow each platform to perform the role it is best suited for while ensuring that the information required by the wider business process moves reliably between them.
At HIPER, we approach HubSpot integrations from this wider perspective. Rather than treating CRM as an isolated implementation, we consider how HubSpot connects with ERP, data, automation and AI across the wider business architecture.
