Why a 2-Hour Codebase Audit Should Always Precede a Software Rewrite Quote

A software consultant argues that quoting a full system rewrite without first auditing the codebase is either guesswork or financially motivated, and insists on a two-hour code review before providing any estimate. The consultant notes that most troubled systems do not require a complete rewrite, but rather targeted fixes to a small number of genuinely broken components, which is typically faster and cheaper. The audit framework is designed for small-to-mid SaaS products under 100,000 lines of code, with larger distributed systems requiring days of structured assessment rather than hours. Before beginning, the consultant requests repository access, infrastructure details, a database schema dump, a three-month incident log, and a clear description of what the client considers broken. The incident log is highlighted as the most undervalued input, since recurring user-facing errors reveal real risk patterns that static code analysis alone cannot surface.
