How much does it cost to replace spreadsheets with a custom system

Many companies rely on spreadsheets until operations become too complex. At that point, the question arises: how much does it cost to move to a structured system? There is no fixed answer. Costs depend on complexity, integrations and the level of customization required.

The real investment is not only in technology, but in structuring processes properly.

Why this happens / what to evaluate

Spreadsheets are flexible and easy to start with. However, they do not scale well. As operations grow, issues such as duplication, errors and lack of control appear.

• Manual rework
• Frequent errors
• Lack of visibility
• Data fragmentation
