Introduction

A smooth checkout process means more sales, less cart abandonment, and happier customers. With Merchant.js's tools, you can implement these 10 essential tips to make your checkout experience work better for your users.

Key Checkout optimization strategies

  1. 1

    S One-Step Checkout Flow

    Reduce abandonment by minimizing form steps. Merchant.js makes it simple with one-step APIs: 

    merchant.checkout
    .create({ 
        autoCollect: true,
        oneStep: true,
        items: [...]
    });
  2. 2

    Use Smart Address Validation

    Prevent shipping errors before they happen with built-in address validation tools: 

    merchant.validation
    .validateAddress({ 
        address: userAddress,
        country: 'US'
    });
    See validation docs →
  3. 3

    Add Guest Checkout Option

    Let customers skip registration with simple code: 

    merchant.checkout
    .create({ 
        guestCheckout: true,
        emailCapture: false
    });

    See how this improves your conversion rates by up to 30%.
