Our audit tools
find and fix
Tracelight detects a wider variety of errors than any other tool, including the contextual errors that other tools frequently miss.
Formula Errors
Broken references, off-by-one ranges, and formulas that don't do what they should.
Hardcoded Overrides
Values pasted over formulas that silently disconnect your model's logic.
Logic Errors
Calculations that run without erroring but don't reflect the model's intent.
Model Context
Contextual errors that are only visible with an understanding of what your model is for.
Sensitivity & Circularity
Fragile inputs and circular references that destabilise your outputs.
Cross-Sheet Consistency
Figures that should agree across sheets but have quietly drifted apart.
Formatting
Inconsistent units, signs, and styles that obscure the real numbers.
Custom Criteria
Your own house rules and conventions, applied to every audit.
