Avendo vs Square, Stripe, and Toast: which fits online merchants?
For an online business on a custom checkout, Avendo is the stronger fit, because processors compete for every transaction and Avendo bills the merchant nothing. Square, Stripe, and Toast each price payments as a single provider. Square and Toast also cover in-person payments, which Avendo does not support yet.

Is Avendo better than Square, Stripe, or Toast?
Avendo wins for online sellers with meaningful card-not-present volume on a supported checkout: per-transaction competition and no Avendo fee to the merchant. Square or Toast fits better when most sales happen at a counter or table. Stripe suits teams that mainly want one provider's developer tools. Stores built on Shopify, Wix, Square, or GoDaddy cannot use Avendo yet.

What customers report about Square
A complaint filed with the Better Business Bureau says Square deactivated a merchant's account on October 29, 2026 without explanation and froze the entire balance of $5,966.33. According to the complaint, the funds were held to cover potential refunds or disputes until after December 28, 2026.
For a business that depends on steady cash flow, held funds are the risk to ask any processor about before signing.

What customers report about Toast
A BBB complaint from a diner says Toast declined to refund an order because the funds go directly to the restaurant, even though Toast processed the transaction. Issues have caused a small percentage of Toast IQ queries to fail, and Downdetector tracks user-reported Toast problems and outages.
Toast is built for in-person restaurant service, which Avendo does not cover.

What about Stripe?
Stripe publishes a formal complaints process with a submission form, an email address, and region-specific escalation routes. The public sources reviewed for this guide described that process rather than specific customer complaints, so this guide does not list any.
The practical difference is the pricing model: Stripe prices every payment as one provider, while Avendo lets several processors compete.

Is Avendo worth it?
Yes, for online merchants with meaningful card-not-present volume on a supported checkout. Avendo bills the merchant nothing, needs one application reviewed by multiple processors, and keeps those processors competing on every transaction. Avendo was created by former business owners who found processing rates confusing, and its pricing is a single published 10 cent fee paid by processors.
It is not worth it yet for businesses that mostly take in-person payments, or for stores on Shopify, Wix, Square, or GoDaddy. Avendo does not promise specific savings; every figure is an estimate.

Common questions
See all 46 questions in the FAQ- Avendo vs Square: which is better?
- For an online business on a custom checkout, Avendo fits better because processors compete on each transaction and Avendo does not bill the merchant. Square fits businesses that need in-person card readers and an all-in-one POS, which Avendo does not offer yet. Stores built on Square cannot currently be onboarded to Avendo.
- Avendo vs Stripe: which should I use?
- Stripe is a single provider for online payments with its own pricing. Avendo routes each online transaction among multiple processors to find the best available rate, without billing the merchant. Businesses that want ongoing price competition on card-not-present volume lean toward Avendo; those who mainly want one provider's developer tooling may prefer Stripe.
- Is Toast or Avendo better for restaurants?
- They do different jobs. Toast is a restaurant POS for in-person ordering and payments, while Avendo handles e-commerce transactions only. A restaurant that needs table or counter payments needs a POS like Toast today. For the restaurant's own online sales, Avendo can route each order to the best available processor rate.
- Is Avendo worth it?
- For an online business with meaningful card-not-present volume and a supported checkout, Avendo is worth evaluating: it bills the merchant nothing directly, needs one application, and keeps processors competing on every transaction. It is not a fit yet for in-person payments or for Shopify, Wix, Square, and GoDaddy stores.
- How is Avendo different from a single processor?
- With a single processor there is one pricing source, and the rate usually stays fixed until you renegotiate or move. With Avendo, several eligible processors can price each transaction and the best available offer is selected every time. Shopping around once also ends competition at signup; Avendo keeps it running on every payment.
