## Avis

### "Stax - Better than the rest\!" — 5.0/5

> **Utilisateur vérifié** | *9 septembre 2025* | Vente au détail | Taux de recommandation : 10.0/10
> 
> **Avantages**: While Stax is becoming a larger and larger you still maintain communications with their fantastic US based support team who will do EVERYTHING in their power to chase down any issue you may have.
> 
> **Inconvénients**: Rate changes can be hard to follow however that is due to the underlying processor changing and Stax works with you to ensure smooth processing.
> 
> Overall Stax is 10/10 I've shopped around for other solutions and no one else can compare. On either price or support.

### "Always a good experience" — 5.0/5

> **Syeda** | *28 février 2026* | Santé, bien-être et fitness | Taux de recommandation : 3.0/10
> 
> **Avantages**: Stax is very easy to use. It also has simple billing and reasonable fees compared to other terminals
> 
> **Inconvénients**: Not really much. It would’ve been nice if the online terminal was free to use as part of the subscription
> 
> Great experience. Had such a good history with Stax, I’m not using it at my second office that recently opened

-----

### "Worst Support experience" — 1.0/5

> **Jaspreet** | *12 décembre 2025* | Vente au détail | Taux de recommandation : 0.0/10
> 
> **Avantages**: Processing rates are competitive, even though they are higher than promised. Sales team was responsive enough.
> 
> **Inconvénients**: Support is extremely slow and incompetent to resolve critical issues even after 6 weeks of reporting. Even the leadership doesn't understand how much 'compliance violation' can hurt a merchant and Stax itself.
> 
> Easy to sign up but worst experience getting simple but critical technical issues. Support and leadership both have been disappointing ao far.

### "Stac works well" — 4.0/5

> **Tom** | *25 février 2026* | Automobile | Taux de recommandation : 10.0/10
> 
> **Avantages**: I like the ease of set up. And that you can use multiple devices to run the dongle. It makes it easy.
> 
> **Inconvénients**: I’m frustrated that deposits are not always next business day. Sometimes it happens next day others two days. Sometimes it’s there early in the morning others late in the afternoon.
> 
> I’m happy with it. If the direct deposit occurred next business day morning.   That’s my only real gripe.

### "Great service and communication" — 5.0/5

> **Joe** | *25 février 2026* | Logiciels de construction | Taux de recommandation : 10.0/10
> 
> **Avantages**: They are great with communicating with the business owner, they even helped with completing the PCI compliance forms.
> 
> **Inconvénients**: No cons yet.  The app and SimpleSwipe are extremely easy to use tools for payment processing. Would highly recommend
> 
> Very satisfied and affordable processing company.  It's easy to understand their fees and status of payments.
