The outcome

Solution details

We ask for a sample without sensitive data and review data entry, repeated calculations and common errors. Where useful, we separate inputs, calculations and reporting.

We verify formulas against agreed examples and boundary values. The workbook comes with guidance so your team understands updates and can keep using it independently.

FAQ

Common questions

Do you need live business data for an estimate?+

An anonymised copy with fictional values is enough for an initial review if it preserves the structure and problematic formulas. Remove personal data, passwords and payment information. Live-file access is discussed only when necessary.

When should a spreadsheet become a dedicated system?+

When you need distinct permissions, an audit trail, reliable concurrent editing or relationships across many datasets. First compare the cost of errors and manual work with building and maintaining a new system.
