Has Your Business Outgrown Excel?
What started as a practical spreadsheet often becomes difficult to manage
as more users, departments, approvals and compliance requirements depend on it.
Typical Excel Risks
- Sensitive data is visible to everyone
- Increasing effort to maintain the sheet
- Unclear permissions with growing compliance requirements
- Nobody knows which version is authoritative
- Manual copy & paste between systems
- Critical formulas understood by only one employee
- Unclear whether data is complete, approved or up to date
- Users must wait for others to finish editing
If several of these sound familiar, the issue is usually no longer Excel itself.
The issue is that the business process has outgrown Excel.
From Excel To Business Application
What changes after modernization.
Today with Excel
- Employees waiting for others to finish

After modernization
