Why Vertex Customers Are Looking Elsewhere (And Where They're Going)

When Vertex released its Q2 2025 earnings report, it wasn’t the adjusted EPS or revenue growth that caught attention. It was the pattern: two consecutive quarters of net customer loss.

That kind of churn doesn’t happen in a vacuum. It signals frustration. Long implementation timelines. Bloated maintenance costs. Outdated architecture. And for teams in telecom, ECM, and high-volume tax environments, it points to a tax engine that's simply not keeping up.

Why companies are leaving Vertex

Vertex has been around for decades, but that legacy comes at a cost:

• Sluggish implementation cycles that stretch into quarters
• High total cost of ownership tied to legacy infrastructure
• Rigid configurations requiring specialized scripting
• Limited agility for exemption handling and telecom tax nuances

Searches like "Vertex O Series too complex" or "Vertex exemption issues" are becoming more common. And when product updates are slow and support cycles feel ticket-based and reactive, teams start asking: "What else is out there?"

Here’s why former Vertex customers are switching:

• Proactive, human support that understands your edge cases

Vertex vs. CereTax: What’s the difference?

A smarter switch

We’re not here to bash Vertex. It served its purpose for a time. But today, enterprise tax teams need more than a legacy tool retrofitted for the cloud. They need speed, agility, and lower total cost of ownership.

CereTax delivers on all three.
