Pricing Model | Stax Payment Review

Pricing Model

Subscription-Based Pricing Structure

Its subscription-based pricing model sets Stax apart from the traditional percentage-based transaction fee structures. Instead of charging a percentage of the transaction, Stax charges a flat monthly fee and a minimal per-transaction fee. This could be most helpful for those running a great many transactions.

Comparison with Traditional Percentage-Based Transaction Fees

Most traditional payment processors charge a percentage of the transaction amount, which can add up for businesses that process a large volume of transactions. In contrast, the costs are much more predictable because Stax operates on a subscription model. Fees are as low as $99 per month plus $0.08 transaction fees for in-person transactions and $0.15 for manually keyed transactions. This structure can save businesses thousands of dollars, especially at higher sales volumes, thus being less expensive than a percentage-based pricing model.

Detailed Breakdown of Monthly Fees and Transaction Costs

The key subscription plans that Stax offers are three in number:

  1. Growth Plan: $99/month includes basic analytics, virtual terminal, and free surcharging capability.
  2. Pro Plan: $159 monthly; complex analytics, digital invoicing, secure credit card information storage.
  3. Ultimate Plan: This plan costs $199 per month and comes with all of the Pro features plus premium analytics, one-click shopping carts, and an Account Manager.

Combined with each plan are per-transaction fees: $0.08 for in-person transactions and $0.15 for manually keyed transactions over the interchange rate.

Cost-Effectiveness for Different Business Sizes

One of the biggest pros of using Stax is that their pricing model is very reasonable for companies with large volumes. For instance, companies processing over $8,000 per month might entail a subscription model that is significantly inexpensive compared to traditional processors. However, small businesses or businesses with uneven transaction volumes may find traditional percent-based fees more predictable and manageable.

In other words, while a subscription model from Stax will save money and add predictability for high-volume companies, it requires careful consideration for smaller enterprises.
