What does a revenue leakage audit require?
The audit follows real opportunities across marketing, sales and operational hand-offs. Missing evidence is itself a finding when it prevents the business from understanding conversion.
Useful evidence
The goal is not to produce a perfect data warehouse before diagnosis.
Website and campaign analytics
Calls, forms, inboxes and messaging enquiries
CRM or spreadsheet records
Response-time and follow-up practices
Proposals, wins, losses and repeat work
What the audit should produce
A useful audit distinguishes confirmed leakage, probable leakage and unknowns, then orders repairs by value, confidence and effort.
What it should not claim
Lost revenue should not be converted into a dramatic number unless the source evidence supports a defensible estimate.
