## The answer, as recorded

Asked on 2026-09-16 through Claude (Anthropic) with web search (model claude-opus-5).

> The short version: the right answer depends almost entirely on **how you sell** and **how much you process per month**. Here's who I'd actually name, in order:
> 
> **1. Square - best default for in-person / new businesses**
> $0 monthly fee, free POS software, free reader, no contract. You can be taking cards the day you sign up. Rates on the free plan are 2.6% + $0.15 in person, 3.3% + $0.30 online, 3.5% + $0.15 keyed. Note that Square raised the free-plan online rate from 2.9% to 3.3% in January 2026 - so if you're online-heavy, Square is no longer the cheap option it used to be. Their $49/mo Plus plan brings online back to 2.9% + $0.30.
> 
> **2. Stripe - best if you sell online or need to build something custom**
> Flat 2.9% + $0.30 online. The API and docs are the industry standard, and it has the deepest support for subscriptions, marketplaces, and custom checkout flows. Downside: the flat rate never improves with volume unless you negotiate, and many add-on products (Billing, Connect, Tax) carry their own percentage fees that stack up.
> 
> **3. Helcim - best once you're above roughly $10-25K/month**
> Interchange-plus pricing (starts around interchange + 0.15% + 6¢) with automatic volume di

Answer Watch records what one AI answer engine said on one date, nothing more. Each page names the engine and the model, carries the date the question was asked, and lists the brands that appeared in the answer in the order the engine gave them, with the sources it cited. It is a measurement, not a ranking, not a recommendation and not a claim about the world. Brands that did not appear in an answer are not named on any public page.
