IBM Controller is IBM’s financial consolidation and close solution, designed to help group organisations automate statutory consolidation, reporting, and financial governance.

IBM Controller is available in two interfaces: IBM Controller Web and IBM Controller Classic. A common question we hear from customers is: what’s the difference between them, and which users need which interface?

This article explains what each interface is used for, how they differ, and how they typically work together in practice.
The information below applies to both cloud and on-premise implementations.

IBM Controller Web #

IBM Controller Web is a browser-based interface designed with usability and accessibility in mind. It provides a modern experience for users involved in data submission, review, and reconciliation.

Controller Web is most commonly used by:

• Users submitting financial data

• Users responsible for submissions across multiple companies

• Finance users focused on completing a clean, on-time close rather than system administration

It is intentionally designed for business users, not technical administrators.

IBM Controller Web offers  features that are not available in IBM Controller Classic, including:

• Mobile access.
• Data upload, account and intercompany reconciliation and  journal entry in an interactive workflow
• Intercompany reconciliation in the reporting company currency.
• A reporting status window that fully integrates with the submission workflow and consolidation processing
• Clear visibility of timelines and submission deadlines

The result is a more intuitive experience that helps local finance teams understand what needs to be done, by when, and what is still outstanding.

IBM Controller Classic #

IBM Controller Classic is the rich-client desktop application and remains essential for users performing more advanced consolidation and system administration tasks.

It is typically used by:

• Group finance teams

• System administrators

• Power users responsible for complex consolidation logic

IBM Controller Classic provides deeper technical and functional control, including:

• System maintenance such as company, account and form structure amendments.
• Consolidation tasks including intercompany elimination, investment elimination, cash flow and group adjustments.
•  Advanced business rules and advanced formula calculations
• User and Data Security maintenance.
• Integration with IBM Planning Analytics for financial planning and analysis using Controller data

While powerful, Classic is less intuitive for occasional users and is therefore not typically used for day-to-day data

submission.

Which interface is right for your users? #

In practice, most organisations use both.

IBM Controller Classic is essential for maintaining the Controller database, running consolidations and managing eliminations, adjustments, and security.

Users who maintain the system in Classic should also have access to Controller Web, allowing them to test structural changes and view the system as business users experience it.

IBM Controller Web is ideal for local finance teams submitting data, users responsible for multiple company submissions and finance teams needing clear workflow guidance and reconciliation visibility.

Group finance teams also benefit from Controller Web by monitoring submission progress, identifying bottlenecks early and gaining real-time visibility into close status across the group

Users reporting data into Controller benefit from using Controller Web because of its ease of use and because its workflow guides them through to a reconciled and complete submission.
