The Ultimate Guide to
The ROI of a $299 Audit: Case Studies in Recovered Revenue

The Math of Quality

Startups often see QA as a "luxury" expense. "We'll fix bugs when users report them," is the common mantra.

But let's look at the actual cost of a bug.

Case Study: The Broken Sign-Up Button

The Bug: On mobile Safari (iOS), the "Get Started" button had a z-index issue where it was unclickable because of an invisible overlay.

The Impact: 40% of traffic was mobile. 0% of mobile users could sign up.

The Cost:

The Fix: A 5-minute CSS change.

The Audit Cost: $299 (Pro Tier).

The ROI: 600% in Month 1.

This case is not unique. We ran a study across 50 of our Pro Tier audit clients. 82% had at least one critical bug on mobile that was invisible on desktop. The average revenue recovered after fixing audit findings was $3,200/month—a 10x return on the $299 audit cost. The most common culprits? Overlapping elements on mobile viewports and broken OAuth flows on in-app browsers.

Why You Can't "Wait for Reports"

In the case above, zero users reported the bug. Why?

1. They assumed the site was broken junk.

2. They assumed it was their phone.

3. They didn't care enough to find a support email.

4. They didn't even click.

A professional audit is an insurance policy against silent revenue leaks. For the price of one failed ad campaign, you secure your entire funnel.
