To get started accepting credit card payments online quickly and without getting bogged down by monthly subscription fees or complex merchant account applications, flat-rate aggregators are your best bet. They have zero monthly fees and straightforward "pay-as-you-go" pricing.
The top simple, low-fee options to consider depend on how you plan to build your site:
Note: If your transaction volume scales past $10,000 a month, flat-rate processors become more expensive than "interchange-plus" providers like Helcim , which trade a wholesale markup for lower per-transaction percentages.
To help narrow down which one makes the most sense for you:
If you’re a U.S. business and want **simple setup + reasonable fees**, I’d start with **Stripe**. - **Stripe** — 2.9% + 30¢ per successful domestic card transaction, with no setup or monthly fee on standard pricing.

If you’re a U.S. business and want simple setup + reasonable fees, I’d start with Stripe.
My practical pick: Stripe for a primarily online business; Square if you want a simple system that can handle both online and physical sales.
If you tell me roughly your average transaction size, monthly online sales, and whether you need subscriptions/invoices, I can compare the actual dollar cost of Stripe vs. Square vs. PayPal for your business.
If you're in the U.S. and want **simple setup + reasonable fees**, I'd start with **Stripe**. - **Stripe:** 2.9% + $0.30 per successful domestic card transaction, with no setup or monthly fee on standard pricing. It's particularly good if you have a website or online application and want a clean checkout/API.…
If you're in the U.S. and want simple setup + reasonable fees, I'd start with Stripe.
Stripe for a normal website selling products/services online. It's inexpensive enough to start, has no monthly fee, and scales well if you later need subscriptions, invoices, Apple Pay/Google Pay, or a custom checkout.
If you tell me what you're selling, your typical transaction size, and roughly how many payments/month, I can calculate which processor would actually cost you the least.
For getting started quickly and simply online, three main processors dominate the small business landscape. They all feature **no monthly fees** (you only pay when you make a sale), but they differ slightly in cost and complexity.[](https://onenine.com/stripe-vs-square-vs-paypal/)…

When you are starting out online, the "simplest" processors use a flat-rate pricing model (no monthly fees, you just pay a fixed percentage per sale). While specialized "interchange-plus" pricing can be cheaper at high volumes, flat-rate options are the easiest to set up in an afternoon without dealing with traditional merchant account underwriting.
The best simple, low-fee options to get started include:
If you're in the U.S., I’d start with **Stripe** for a typical online business. - **Stripe:** 2.9% + 30¢ per successful domestic card transaction, with no setup or monthly fee on standard pricing.

If you're in the U.S., I’d start with Stripe for a typical online business.
Choose Stripe if you're primarily selling through your website and want a clean, developer-friendly setup.
Choose Square if you expect to combine online payments with a physical store, appointments, invoices, or a POS system.
For example, on a $100 sale, a 2.9% + 30¢ rate costs $3.20, leaving you $96.80 before other costs.
If you tell me what you're selling, your approximate monthly sales, and whether you need subscriptions or just one-time payments, I can tell you which processor is likely cheapest for your specific situation.
