“Unpacking the Cost Challenges of Vertex O Series”

3.0
Jan 24, 2025
The tax engine of the Vertex O Series is something that cannot be overlooked; however, the pay as you go price model is not very helpful for planning. For a small enterprise, it may not be such a big deal. But for companies that are growing at a very fast rate, the cost becomes a real problem.

Vertex O Series Likes & Dislikes

Like

I like how accurate the computations are. Provides detailed configuration and very powerful customization.

Like

Vertex O Series handles such computations without any problem while also making sure that the right tax rules are applied to my transactions. The software has been a good fit for me as it interconnects well with my current ERP system reducing on data entry mistakes.

Like

-Accurate tax calculations based on jurisdictional level - Comprehensive reporting features - Simple and efficient UI - Improved SOX and Audit control - Vertex university and annual exchange

Dislike

I don't like the pricing model.

Dislike

Vertex charges a percentage of your total revenue, which means that as our business grows, our tax software bill rises as well. This seems wrong because I am not receiving anything more than what has been offered for the price I am paying.

Dislike

Lack of automation esp in Import/Export processes and monthly reporting areas Absence of direct E-filing options for few countries Search functionality within the portal could be improved

    Understanding the Revenue-Based Pricing Structure of the Software

    2.0
    Aug 13, 2024
    While the product performs well, the pricing structure is nonstandard. Their fees are based on overall customer revenue. Thus, the better a customer does, the more they charge. This is despite the fact that the software is not providing any improved capabilities, and the customer is providing all the costs of on-premises services. Additionally, they don't provide a contractual prices for each "Tier" of revenue and refuse to negotiate any changes to the fee structure.
