Common challenges of SAP Business One in day-to-day business

Over time, many companies reach the limits of the features and capabilities SAP Business One offers. If you currently use SAP B1, some of the following challenges and concerns may sound familiar. If so, migrating to Business Central could be your next step.

Challenge #1: Limited scalability

Because SAP Business One was designed specifically for small and midsize businesses, it can reach its limits as a company grows, especially as transaction volumes increase or processes become more complex.

• “Our company is growing, but SAP B1 feels like a bottleneck.”

Challenge #2: Limited cloud options

Although SAP Business One is available as a hosted version, it was primarily developed for on-premises use. As a result, it lacks key benefits of a native cloud solution, such as automatic updates, flexible scalability, and consistently high availability.

• “Why do we still have to take care of updates and servers?”

Challenge #3: Some integration gaps

SAP Business One can connect with other tools, but many companies face challenges when setting up those connections. Complex interfaces and limited native integrations make it particularly difficult to use modern Microsoft solutions such as Teams, Power BI, or Office 365 seamlessly.

• “Every time we try to connect Power BI or Teams to SAP B1, we run into complications.”

Challenge #4: Greater maintenance burden

Because many companies use SAP Business One on-premises, they are responsible for updates, server maintenance, and backups. This takes additional time and resources that could be put to more productive use elsewhere.

• “Our IT department spends too much time managing our ERP system.”

Challenge #5: Costly customizations

SAP’s ERP system can be adapted to specific requirements, but custom extensions often require specialized expertise and significant development effort.

• “Every small change costs us a lot of money and time because we need external developers.”

Challenge #6: Poor ease of use

SAP Business One’s interface is not especially intuitive and often requires a longer learning curve, particularly for users without an IT background.

• “It takes forever to train new employees.”

When does it make sense to switch to Microsoft Business Central?

These challenges and concerns show that SAP Business One can increasingly become an obstacle for many growing companies. A modern ERP system should not only support existing processes but also lay the foundation for further growth. Microsoft Dynamics 365 Business Central offers a powerful, flexible solution that can prepare your business for the future.

But what does a migration from SAP Business One to Business Central involve? What steps are needed to ensure a smooth transition?

Structured transition: How to migrate from SAP to Business Central

The migration from SAP Business One to Microsoft Dynamics 365 Business Central requires a strategic approach. Nexova Dynamics uses an iterative implementation process: Work is delivered in small increments, with regular progress updates so adjustments can be made early. Where possible, both systems run in parallel, allowing employees to get familiar with Business Central before the final switch.

This approach minimizes risks, reduces downtime, and ensures a smooth transition. Companies can quickly benefit from the new ERP platform. Below, we take a detailed look at each migration step and show how to make the switch successfully with a Microsoft partner.

Step 1: Analysis and planning: Assess the current state and define goals

A thorough analysis and a requirements specification form the basis of every successful migration. Together with your implementation partner, you will identify:

• Which business processes are covered by the existing SAP B1 environment?
• Which data is used?
• How should the new system be set up?
• Which interfaces and integrations need to be connected?
• Which Business Central features are required?
• Which processes should be optimized or automated?
• Which security and compliance requirements must be met?

You then develop a migration strategy, create a timeline, and assign responsibilities.

Step 2: Basic system setup

Before Business Central goes into production, the system is carefully configured. This includes basics such as user roles as well as individual requirements from the previously defined specifications. The key steps in this phase are:

1. Define company-specific settings

• Enter company data, tax information, and currency settings
• Set the chart of accounts and accounting policies

2. Configure user and role management

• Create user accounts with role-based permissions
• Ensure integration with Microsoft 365 for single sign-on
• Define release and approval processes

3. Adapt business processes and automation

• Set up workflows for accounting, purchasing, and sales
• Configure dashboards and reports for a better overview

Step 3: Data migration: Ensure error-free transfer

Data migration is a critical step in an ERP transition. To avoid errors, we take the following measures:

• Clean data in SAP B1: Remove duplicate, outdated, or incorrect data
• Export and transform data: Transfer relevant master data, accounting data, and transaction history into the Business Central format
• Initial data review: Spot-check and compare data against original values to identify inconsistencies early

Final system validation takes place at a later step to ensure a smooth go-live.

Step 4: Integration with existing systems and interfaces

Another important point is integration with existing systems. The ERP must communicate seamlessly with them so processes continue to run smoothly. Common integrations include:

• CRM systems (e.g., Salesforce)
• E-commerce platforms (e.g., Shopify, Magento, WooCommerce)
• Inventory management and logistics systems
• Payment providers

Switching to Business Central may make some existing systems redundant because their features can now be handled directly in the ERP. We assess this in the first step.

Step 5: Testing and system validation for a smooth start

Once Business Central is set up, the data has been migrated, and all interfaces are connected, the new software must be thoroughly tested. This reduces the risk of errors in production and ensures all processes work smoothly.

Important test areas include:

• Check data consistency: Is all migrated and synchronized data complete and correct?
• Run through processes: Test accounting, orders, inventory management, and reports in a test environment.
• Validate interfaces: Do CRM, e-commerce, and accounting systems work seamlessly with Business Central?
• Test permissions: Are all user accesses and roles configured correctly?
• Load and performance testing: Ensure system stability under real-world conditions.

After the successful testing phase, final optimizations are made and go-live is prepared.

Step 6: Go-live: Transition to production

A well-planned go-live minimizes risks and ensures a smooth start with Business Central. The following measures are critical:

1. Final preparations before go-live

• Final data reconciliation to ensure all data was migrated correctly and completely.
• Employee training to ensure users can confidently handle the most important processes.
• Back up the old ERP system so it can be accessed in an emergency.

2. Go-live day

• Activate Business Central and deactivate SAP B1 or switch it to read-only mode.
• Monitor initial transactions, such as entries, orders, and invoices.
• Make a support team available to resolve questions or issues immediately.

3. After go-live: Monitoring and optimization

• Conduct regular status checks to identify bottlenecks or errors early.
• Gather user feedback to identify potential improvements.
• Fine-tune workflows if processes are not yet running efficiently.

Step 7: Continuous optimization and development

After go-live, Business Central is continually optimized to make processes more efficient and remain competitive.

• System and process reviews: Regular analysis and user feedback to identify opportunities for improvement.
• Extensions and integrations: Use new Microsoft updates and implement additional add-ons and interfaces.
• Training and change management: Ongoing employee training and adjustments to support business growth.

Common pitfalls and mistakes during migration

A well-planned, structured migration is key to a successful Business Central implementation. From preparation and data migration to system integration and continuous optimization, every step helps make business processes more efficient and maintain long-term competitiveness.

Various challenges can arise during an ERP transition, from unexpected data migration hurdles to the difficulty of integrating systems smoothly.

• Poor data cleanup before migration: It is essential to clean data and remove outdated information before migrating. Incorrect or incomplete data can make the migration process more difficult and cause problems in the new system.
• Lack of user acceptance: A new system often requires changes to how people work. Without sufficient training and change management, employees may not accept it, leading to inefficient use. Training is therefore essential.
• Risk of business interruption: A smooth transition is essential to avoid major business interruptions. Careful planning, testing, and pilot projects help minimize downtime and keep business operations running.
• Failure to adapt business processes: SAP Business One and Business Central differ in structure and features. Existing processes must be reviewed and adjusted to ensure efficient use. Without these changes, workflows may become inefficient.
• Underestimating ongoing optimization: Go-live is only the beginning. Regular optimization and adjustments are needed to realize Business Central’s full potential and meet future challenges.

The good news: These common pitfalls can be addressed, and the risk of errors can be minimized by working with an implementation partner who knows all the processes and potential challenges involved in making the switch.

What does an ERP transition to Business Central cost?

Initial migration costs include license fees, basic configuration, data migration, customizations, and employee training. The resources required can vary depending on the complexity of the existing system and the desired customizations. Standard processes can be transferred relatively quickly, while integrating existing interfaces or custom workflows requires more resources.

Investing in support from an experienced Microsoft partner such as Nexova Dynamics can pay off in the long term by helping avoid errors and inefficient processes from the start. Migration project costs start at CHF 12.900.

How does Business Central deliver efficiency gains?

Using Business Central reduces costs in the long term because, as a cloud solution, it does not require expensive servers, maintenance, or manual updates; these are already included in the subscription. Automated processes, seamless integration with Microsoft 365 and Power Platform, and scalable modules let the system grow with your company without requiring major investments in new IT infrastructure or custom development. As a result, operating costs remain largely constant even as the company grows, while efficiency and productivity increase.
