5 points to consider before implementing Business Central and a customer Portal

The technology may be ready, but are your processes, data, users, and ownership model ready to support it?

Implementing Microsoft Dynamics 365 Business Central can strengthen control over finance, sales, purchasing, inventory, service, and reporting. A customer portal can extend selected processes to customers, vendors, distributors, and service partners. The risk comes when the two are treated as separate projects. Business Central may work well internally while external users still depend on email, spreadsheets, and staff intervention. Before implementation begins, leadership teams need five decisions that determine whether the connected environment will simplify operations or add complexity.

1. Define the business problem before selecting customer portal features

The first discussion should not be about dashboards or feature lists. It should focus on the operational problem the company needs to solve.

A typical mid-market business may receive orders through email, phone calls, spreadsheets, and messaging platforms. Employees then transfer requests into Business Central, answer recurring status questions, resend invoices, and reconcile information held by different departments. The ERP contains the data, yet customers cannot reach it without asking an employee.

Connect these problems to measurable objectives. The business may want to reduce manual order entry, increase self-service transactions, shorten payment cycles, improve customer-facing information, or reduce routine enquiries.

The best customer portal is not the platform with the longest feature list. It is the one that removes the processes creating the most friction and produces outcomes the business can measure.

2. Map the complete process beyond Business Central

ERP projects often focus on internal departments. A customer portal requires a wider view because the process begins and ends outside the ERP.

Take a common order scenario. A customer creates an order in the portal. Business Central validates pricing, availability, credit limits, taxes, and approvals. The warehouse processes it. A logistics system returns the shipment update, and the customer sees the new status without contacting operations.

That flow may also involve payment providers, CRM platforms, document storage, EDI services, and APIs. Mapping the process from the first customer action to the final result exposes dependencies before they become implementation problems.

It also clarifies which system owns each record, how data is validated, what happens when an integration fails, and who resolves exceptions. For teams asking how to extend Business Central, begin with the complete business journey, not a list of ERP fields.

3. Decide what the customer portal can show and change

Business Central should normally remain the source of operational and financial information. The customer portal should expose only selected data and actions through a controlled interface.

A purchasing user may create and review orders. A finance contact may access invoices and balances. A warehouse coordinator may review shipments. A manager may need account-wide visibility, while an administrator may invite or remove users.

Before development starts, decide:

which accounts and locations each user can access

which documents and transactions are visible

who can create, edit, approve, or cancel requests

which actions require internal approval

how inactive users are removed

Data quality must also be reviewed. Duplicate accounts, outdated descriptions, incorrect discounts, incomplete shipment statuses, and unmatched payments can all become visible. A customer portal does not hide weak data; it makes the consequences immediate.

Someone must therefore own customer records, products, prices, documents, portal content, and access rights after launch.

4. Start with high-value scenarios and control integration scope

Trying to launch every possible function at once increases cost, complexity, and risk. A stronger approach is to begin with scenarios that customers already need and the business can measure.

Common starting points include order creation and history, invoice and balance access, service requests, shipment visibility, and document sharing.

A portal for ERP/CRM should exchange only the information required for those scenarios. Moving every available field into the external environment creates unnecessary work and makes support harder.

Integration rules should specify what moves from Business Central to the customer portal, what moves back, whether synchronisation is immediate or scheduled, and how errors or outages are handled.

The certified Xpand Portal Connector, available on Microsoft AppSource, supports integration between Microsoft Dynamics 365 Business Central and a secure customer-facing environment. It presents selected ERP data and processes externally without giving customers or suppliers direct ERP access.

Some procedures may exist only because of old system limitations or spreadsheet workarounds. Recreating all of them in a Microsoft ERP portal can make the new environment unnecessarily complex. Configure what creates value and customise only where a genuine operational, contractual, or regulatory requirement exists.

5. Plan adoption, ownership, and measurement before go-live

A technically complete customer portal will not create value unless customers and employees use it correctly.

Internal teams need to understand which activities customers can complete independently, when employees must intervene, how transactions appear in ERP and who handles access requests or errors. Customers need clear onboarding through invitations, short guides, demonstrations, FAQs, and support details.

Assign responsibility for portal administration, data quality, onboarding, support, integration monitoring, security, release planning, and user feedback.

Measure success against the original objectives. Useful indicators include orders submitted online, reduction in manual entry, active portal users, invoices downloaded through self-service, fewer routine enquiries, faster request processing, fewer data-entry errors, and employee time saved.

These measures show whether the customer portal has started to improve efficiency and where the next investment should go.

How the customer portal fits the wider Business Central strategy

Business Central and the customer portal should be designed as one connected operational environment. Business Central remains the source of truth for internal operations and financial control. The external layer gives customers, vendors, and partners secure access to the services, records, and actions they need.

In this model, a customer portal integrated with Microsoft Dynamics 365 Business Central is not a separate website added after the ERP project. It is part of the process design from the beginning.

Xpand Portal supports this approach through configurable access, ready-to-use customer scenarios, and integration capabilities that can be introduced in stages. Companies can start with an order, receivables, or customer-care process and expand as adoption grows. More information is available at xpandportal.com.

What to do next

Before approving implementation, confirm five things: the business problem is measurable, the complete process is mapped, data and access ownership are clear, the first scenarios are limited and valuable, and long-term adoption has an owner. With that foundation, Business Central can manage internal operations while a customer portal gives external users secure, structured access to the information and services they need.
