Stax review

Stax is a payments provider with separate products for businesses and platforms. Stax Pay is its payment processing platform; Stax Connect provides technology and partnership models for embedding payments; and Stax Bill automates subscription billing. CardX by Stax offers programs for passing credit card processing fees to customers through surcharging.

That makes Stax broader than a card processor alone, at least on paper: businesses can look at it for processing, recurring billing and surcharging, while platforms can explore embedded payments. The products are presented as distinct offerings, so we would confirm which ones are included in a specific quote rather than assume one subscription covers the full suite.

The pricing page lists monthly subscription prices based on annual processing volume, starting at $99 per month for businesses processing up to $150,000 yearly. Stax also highlights transparent pricing and access to support from real people. Those are stated selling points, not a published service-level commitment.

The clearest selling point is that Stax addresses several payment needs under one vendor. Stax Pay handles payment processing, Stax Bill is for subscription billing, Stax Connect covers embedded payments, and CardX by Stax offers compliant surcharging programs. If you are comparing providers, that breadth is worth pricing out before stitching together separate vendors.

The published Stax Pay tiers also spell out the monthly subscription and some per-transaction costs. According to the pricing page, the plans include 0% interchange markup and unlimited users. For the two lower tiers, card-present transactions are listed at $0.08 and card-not-present transactions at $0.15. The monthly subscription is $99 for up to $150,000 in annual processing, or $139 for $150,000–$250,000.

Stax says real people are ready to help, and its homepage emphasizes transparent pricing. Those claims may appeal to teams that want a named support option and visible costs while comparing processors. But we would still get the full quote in writing, including the products, equipment and any extra fees that apply to your setup.

The published prices are not a complete cost comparison. The monthly subscription is only one part of the bill: Stax lists per-transaction charges of $0.08 for card-present and $0.15 for card-not-present processing. ACH processing is listed at 1% per transaction, capped at $10. Debit surcharging is listed at 1.25% plus $0.25 per transaction, and terminal protection costs $19 per month.

Volume also sets a hard pricing boundary. The $99 tier covers up to $150,000 in annual processing; the $139 tier covers $150,000–$250,000; and the $199 tier is for $250,000 or more. The page says higher-volume businesses need a custom quote, so the listed price does not tell larger merchants what they will pay. Equipment pricing is not published, and annual billing discounts are not published. The published pricing details also do not list a free trial or prices for Stax Connect, Stax Bill or CardX. We would ask for a quote covering every product and fee before switching.

The pricing page lists monthly subscriptions based on annual processing volume: $99/month for up to $150,000, $139/month for $150,000–$250,000, and $199+/month above $250,000. The first tier jump is $40/month; the next is $60/month, with higher-volume pricing available by custom quote. All three tiers list 0% interchange markup. The first two include unlimited users and card processing at $0.08 per card-present transaction or $0.15 per card-not-present transaction; the $250,000+ tier lists unlimited users but not those transaction rates in the published pricing details.

Add-ons can change the total: ACH is 1% per transaction, capped at $10; terminal protection is $19/month; and debit surcharging is 1.25% + $0.25 per transaction. Equipment prices aren’t published. These are monthly subscription prices tied to annual processing volume, not a stated annual-billing offer; annual billing discounts aren’t published. Stax has no free plan, and trial availability is not published.

The available Stax information names Stax Pay, Stax Connect, Stax Bill and CardX, but doesn’t explain migration steps, data export, contract terms or how to move stored payment details. Those points matter when switching, so ask Stax directly what it can transfer, what your current provider must supply, and whether fees or timing depend on your setup. Equipment pricing is also not published, which makes it worth confirming any hardware costs before you commit.

We don’t have Reddit posts or comments in the published material, so we can’t credibly say what users tend to leave Stax over. Before switching from Stax, request written details on exporting transaction and customer records, ending service, and any effects on subscriptions or embedded payments. The pricing information alone doesn’t establish whether those capabilities or terms are available. Stax’s product range may suit buyers who want payment processing, subscriptions and embedded options from one vendor, but it doesn’t answer the practical questions that determine migration effort or lock-in.
