What is C5, and how does a freelance C5 specialist work?

By Carsten Bjerregaard, Addcapacity.com

Microsoft Dynamics C5 is a classic ERP system that has been widely used among small and medium-sized Danish companies for many years. The system is known for its robust handling of finance, inventory and order flow and has been a central part of many companies’ administrative foundation. Although C5 has now been replaced by newer cloud-based solutions, it is still used in a number of organizations with stable and well-functioning setups. However, the platform requires technical maintenance and business understanding to function optimally. A freelance C5 specialist helps with optimization, integration and possible preparation for migration.

1. What are C5’s basic functions and core purposes?

C5’s core purpose is to combine finance, inventory and order processing into one integrated ERP system. The system supports financial accounting, debtor and creditor management as well as inventory management and invoicing. Its strength lies in stability and proven functionality. Many companies have adapted C5 over time, making the system anchored in their workflows.

Core functions

• Finance and accounting management
• Accounts receivable and payable administration
• Inventory management
• Order and invoicing
• Reporting and key figures

A specific example: A trading company uses C5 to manage both inventory and invoicing in one integrated process.

2. What business value does C5 create?

C5 creates business value by ensuring stable and structured financial management. For companies with well-established workflows, the system continues to provide solid operational reliability. For management, this means an overview of key figures and liquidity. For operations, this means uniform handling of order and inventory processes.

Value-creating elements

• Stable ERP operation
• Overall financial overview
• Efficient inventory management
• Uniform workflows
• Predictable system structure

In practice: A smaller manufacturing company maintains C5 because the system is integrated throughout the value chain.

3. How comprehensive is C5 – and who is the system suitable for?

C5 is typically suitable for small and medium-sized companies with relatively standardized processes. The system is less suitable for organizations that need a cloud-based, international or very complex ERP structure, but functions stably in many established companies.

Typical organizations

• Trade and wholesale companies
• Small manufacturing companies
• Service companies
• Companies with older ERP setups
• Organizations with local installations

An example: A company chooses to optimize its C5 setup rather than migrate immediately.

4. What other systems are available in the same category?

C5 operates in the ERP category and has today been replaced by newer solutions. Many companies are considering upgrading or migrating.

Alternative platforms

• Microsoft Dynamics 365 Business Central
• Microsoft Dynamics NAV
• SAP Business One
• Visma Business

In practice: C5 users often consider transitioning to Business Central as a natural next phase.

5. What role and tasks can a freelance C5 specialist perform?

A freelance C5 specialist works with optimization, troubleshooting and integration. The focus is on ensuring correct data basis and stable workflows. The specialist can also advise on upgrading or migration to newer ERP platforms.

Typical tasks

• System review and optimization
• Data consolidation
• Integration to webshop and CRM
• Reporting and customization
• Preparation for migration

A specific scenario: A freelancer reviews the data quality in C5 before transitioning to a new ERP system.

6. What work and financial benefits can you achieve by using a freelance specialist?

C5 environments require experience, especially if the system has been customized for many years. A freelancer can quickly create an overview and ensure stable operation without extensive consulting projects. The collaboration can be temporary or ongoing, depending on needs.

Advantages in practice

• Quick technical clarification
• Specialized C5 experience
• Flexible resource use
• Lower costs than larger consulting firms

In practice: A company uses a freelancer during year-end to ensure correct reporting.

7. What are the advantages of using a freelancer rather than an agency or consulting firm?

For C5 tasks, many companies choose freelancers rather than larger consulting firms. The need is often specific and requires hands-on insight into the system. Hourly rates are typically 30–40% lower, and the effort can be targeted precisely at the challenges that need to be solved.

Important differences

• 30–40% lower hourly rates
• Direct technical dialogue
• Faster problem resolution
• Less organizational overhead

A typical choice: The freelancer acts as a temporary ERP resource during a transition period.
