How to accept credit card payments online as a small business

Last updated:

To accept credit card payments online as a small business, you need a checkout, a payment gateway, and an approved processor and merchant account, and you should choose your pricing model before you choose a provider.

Online payment processing for small business comes down to six decisions, from where your checkout lives to how your price is set. Getting the pricing model right at the start matters most, because it is the hardest thing to change later. Avendo lets you start with processors competing on every transaction.

What do I need to start accepting card payments on my website?

You need a website checkout, a gateway to transmit card data securely, and a processor that approves your merchant account. Processors will ask for a tax ID, bank account proof, recent statements, business details, and a government ID. Avendo estimates its single application takes about 10 minutes with those ready.

Six steps to accept credit card payments online

  1. 1

    Decide where your checkout lives

    A custom cart on your own site gives you the most payment options. Hosted store builders often push you toward their built-in processor. Avendo currently supports custom-cart integrations.

  2. 2

    Understand the three building blocks

    A gateway carries card details securely from checkout, a processor moves the payment through the card networks, and a merchant account holds approved funds before payout to your bank.

  3. 3

    Pick a pricing model before a provider

    Flat-rate is simplest, interchange-plus often costs less above $10,000 a month, and Avendo routing lets several processors compete on every transaction.

  4. 4

    Gather your documents

    Processors need a tax ID (SSN, EIN, or ITIN), a voided check or bank letter, recent processing or bank statements, business contact details, and a government ID.

  5. 5

    Check security and PCI DSS

    Use PCI DSS compliant processors and gateways. Your own obligations depend on how your checkout touches card data.

  6. 6

    Apply and start processing

    With Avendo you apply once. Eligible processors review your business, and once approved they compete on price for each sale.

Choosing a provider for online payment processing

Questions to ask any provider

  • What will my effective rate be on my real card mix?
  • Which fees are fixed, and which are your markup?
  • When and why would you hold my funds?
  • Can my pricing ever be revisited without switching?
  • Do I need to change my checkout?

Avendo routes each transaction to the best available rate, so your markup is tested on every sale. It never bills merchants, it integrates with checkout pages you may already use, and its dashboard shows how each transaction was priced. It currently serves e-commerce businesses only, and cannot onboard Shopify, Wix, Square, or GoDaddy stores today.

Common questions

Short answers here. The full credit card processing FAQ covers 47 questions.

How do I accept credit card payments online as a small business?
You need a checkout on your website, a payment gateway to carry card details securely, and a processor and merchant account to approve and deposit funds. With Avendo, you apply once, eligible processors review your business, and approved processors compete on every online transaction.
What is the difference between a payment processor, a gateway, and a merchant account?
A gateway carries card details securely from your checkout, a processor moves the transaction through the card networks, and a merchant account is where approved funds land before reaching your bank. Many providers bundle all three. Avendo sits in front of several processors and chooses which one handles each transaction.
What do I need to apply with Avendo?
The application requires five items: your SSN, EIN, or ITIN; a voided check or bank letter showing account and routing numbers; three months of processing statements, or three months of bank statements instead; your business address and contact details; and a government-issued ID such as a driver’s license or passport.
How long does the Avendo application take?
The application takes about 10 minutes to complete if you gather the documents first. Approval timing then depends on the processors reviewing your account. To confirm current timelines for your specific business, contact Avendo directly through its contact page.
What does PCI DSS compliant mean for a small online store?
PCI DSS is the card industry’s security standard for handling card data. Avendo connects merchants to PCI DSS compliant processors and gateways, and its co-founder created the company’s compliance framework under PCI DSS. Your own obligations depend on how your checkout handles card data, so confirm them with your processor or the PCI Security Standards Council.
What types of businesses can apply to Avendo?
Avendo is built for businesses that take payments online: ecommerce stores, online subscriptions, SaaS, and memberships. Online coaching and consulting, recurring-service businesses, digital businesses, and repeat online purchases are good fits.
