Choose the Right Integration Method for Microsoft Business Central
Every company depends on a growing mix of digital tools: ERP, CRM, e-commerce, payroll, BI, and more.
While each serves a purpose, they deliver real value only when they work together. That’s where integration comes in.
For organizations using Microsoft Dynamics 365 Business Central, choosing the right integration method can make the difference between a flexible, future-proof setup and a complex network of fragile connections.
Understanding integration methods
System integration defines how two or more systems exchange data.
Different approaches suit different business needs, from small, straightforward setups to large multi-system environments.
Here are the five most common methods companies use with Microsoft Business Central:
1. Point-to-Point Integration – Simple and Direct
What it is:
Two systems communicate directly, typically within the same cloud or environment, for example, Business Central connected directly to Dynamics 365 Sales.
Why use it:
It’s fast to implement, low-cost, and ideal for smaller businesses or proof-of-concept projects.
Watch out for:
When you add more systems, the number of connections grows exponentially. Managing and updating them quickly becomes complex for IT teams.
2. File-Based Integration – Reliable but Legacy
What it is:
Systems exchange information using files (CSV, XML, JSON), often shared through FTP or secure cloud storage.
Why use it:
It’s a common approach for older or isolated systems that don’t support APIs.
Watch out for:
Files must be transferred and validated manually or on schedules, leaving room for outdated data, missing records, and errors. Over time, this method limits automation and scalability.
3. API-Based Integration – Real-Time and Scalable
What it is:
APIs (Application Programming Interfaces) allow systems to exchange data instantly in real time.
Microsoft Business Central exposes standard REST APIs covering financials, inventory, sales, and more.
Why use it:
- Real-time synchronization
- Reliable and transparent data exchange
- Easier maintenance and scalability
Watch out for:
Custom APIs must be adequately tested to ensure security and performance. Using Microsoft’s standardized endpoints minimizes that risk.
4. EDI ( Electronic Data Interchange ) – structured and standardized
What it is:
A long-standing standard for exchanging structured business documents between partners, purchase orders, invoices, shipping notices, etc.
Why use it:
Many government entities and large B2B partners still require EDI formats such as EDIFACT or X12.
Watch out for:
While highly structured, EDI is inflexible and expensive to modify. It’s best suited for companies that already rely on EDI in their supply chain.
5. Custom Integrations – Tailored but Costly
What it is:
A fully bespoke setup built for a unique workflow, often combining data from several Business Central tables and external databases.
Why use it:
Perfect for specialized processes that can’t be met through standard APIs.
Watch out for: Custom code means higher development and maintenance costs. Each update to Business Central may require retesting or redevelopment.
How to choose the right method
Selecting the best integration approach depends on several factors:
| Consideration | What to Evaluate |
| System Longevity | Will both systems still be used in 5–10 years? Invest in scalable, standard APIs. |
| Data Volume and Frequency | High-volume or real-time data favors API-based or integration-hub methods. |
| IT Resources | Limited internal skills? Avoid heavy custom coding; leverage standard connectors. |
| Complexity of Ecosystem | More than 3–4 connected systems calls for an integration platform or middleware. |
| Budget and Timeline | Point-to-point is cheapest short-term; integration hubs pay off long-term. |
Why Standard APIs in Business Central Are a Safe Bet
Microsoft Business Central includes a wide range of pre-built APIs covering core business entities; items, customers, vendors, orders, invoices, and more.
These APIs follow Microsoft’s standards, which means:
- Faster setup: No need to build from scratch.
- Simplified upgrades: APIs evolve with Business Central versions.
- Lower risk: Security and data consistency are maintained through Microsoft’s governance.
For most organizations, starting with standard APIs offers the right balance between flexibility and stability.
Balancing Short-Term Needs and Long-Term Growth
Integration decisions often start with an immediate requirement — “connect our webshop,” “sync our CRM,” or “automate invoicing.”
But thinking long-term ensures your digital foundation grows with your business.
The right method should:
- Support your future systems, not just current ones.
- Reduce manual maintenance as you scale.
- Align with Microsoft’s cloud-first strategy to stay compatible and secure.
Conclusion
There’s no one-size-fits-all approach to integration. What matters is aligning your technical setup with your business goals.
Whether you start small with point-to-point connections or move directly to an API-based architecture, the key is to standardize, document, and think ahead.
