How to Accept Payments on Your Website: Complete Setup Guide 2026

Whether you are launching an e-commerce store, selling digital products, or offering services online, adding a payment method to your website is a fundamental step. This guide walks through every option available in 2026 so you can choose the approach that matches your business model and technical capability.

Step 1: Choose Your Payment Model

Before selecting a gateway, clarify what you are selling:

Physical products: You need a full shopping cart with inventory management, shipping calculation, and tax handling.

Digital products: Simpler checkout flows work well. You need payment + automated digital delivery.

Services: Fixed price, custom quote, or subscription billing all require different configurations.

Recurring subscriptions: You need a gateway with robust subscription management and automatic retry logic for failed payments.

Step 2: Select a Payment Gateway

Your payment gateway is the infrastructure that moves money from your customer to your bank account. The main options:

Stripe

Stripe is the most developer-friendly option and the default choice for custom-built sites. It handles credit cards, digital wallets (Apple Pay, Google Pay), buy-now-pay-later options, and 135+ currencies. Setup requires adding a JavaScript snippet or using one of the many no-code integrations.

Cost: 2.9% + $0.30 per transaction.

PayPal

PayPal has the broadest consumer recognition and the fastest checkout for customers who already have a PayPal account. Adding a PayPal button to any website takes minutes with no coding. However, the transaction fees are slightly higher than Stripe for credit card payments.

Cost: 3.49% + $0.49 per transaction (standard checkout).

Square

Square is ideal if you also sell in-person, since it unifies online and physical payment processing on one platform. The online checkout is clean and easy to set up without developer help.

Cost: 2.9% + $0.30 per transaction.

Shopify Payments

If you are building on Shopify, using Shopify Payments eliminates the additional 0.5-2% fee that Shopify charges when using third-party gateways. Everything is configured within the Shopify admin.

Step 3: Choose Your Integration Method

No-code options: Platforms like Shopify, Squarespace, and Wix have payment processing built in. Enable it with a few clicks. Best for non-technical business owners.

Pre-built checkout pages: Stripe Checkout, PayPal Standard Checkout, and Square Online Checkout let you redirect customers to a hosted page. No coding required, but you lose some brand control.

Custom integration: Embedding a payment form directly in your site gives you complete control over the checkout experience but requires developer work (or use of a well-documented SDK).

Step 4: Set Up Security

Payment pages must use HTTPS. Modern web hosts provide free SSL certificates via Let Encrypt. Confirm your site shows a padlock icon before going live.

If you are collecting card numbers directly (not using a hosted checkout), you must comply with PCI DSS standards. Most small businesses avoid this complexity by using hosted checkouts or tokenization provided by gateways like Stripe.

Step 5: Configure Tax Collection

Tax requirements vary by location and business type. Key considerations:

• Sales tax: Required on physical goods in most US states. Stripe Tax, TaxJar, and Avalara can automate calculation.
• Digital goods: Rules vary significantly by country. EU VAT applies to digital goods sold to EU customers.
• Services: Generally not subject to sales tax in most US states, but exceptions exist.

Step 6: Test Before Launch

Before accepting real transactions, test your checkout flow thoroughly:

1. Use test card numbers provided by your gateway (Stripe provides 4242 4242 4242 4242 for testing)
2. Test declined cards and error states
3. Test the post-payment confirmation email
4. Test from a mobile device — most purchases happen on phones
5. Confirm the payment appears in your gateway dashboard

Ongoing: Monitor and Optimize

After launch, watch your cart abandonment rate. High abandonment at the payment step signals friction in your checkout. Common fixes include adding more payment methods (Apple Pay reduces friction significantly), reducing form fields, and adding trust signals near the payment button.

Our Recommendation

For most small businesses getting started, Stripe with its hosted Stripe Checkout provides the best balance of security, capability, and ease of integration. If you are on Shopify, use Shopify Payments. For the simplest possible setup requiring zero code, a PayPal button is functional in minutes.
