   Online payments aren’t optional anymore—they’re expected. Today’s customers:

   Not offering digital payment options? That’s like not having a phone number for your business.

   Benefits:

   •  Faster cash flow (get paid in 1–2 days)

   •  Global reach

   •  Better customer experience

   •  Simplified bookkeeping

    Step 1: Set Up a Business Bank Account

   Before you accept payments, you need a business bank account to receive the funds.

   Why it matters:

   • Keeps business and personal money separate

   • Helps with taxes and legal protection

   • Looks professional

   How to set it up:

   • Choose a business-friendly bank or credit union

   • Bring your business license, EIN, and formation docs

   • Look for perks like mobile banking and low fees

   • Consider getting a business debit and credit card

   ---

    Step 2: Choose a Payment Processor

   Your payment processor moves money from your customer’s card to your business account.

   Some include extras like fraud protection, invoicing, and analytics.

   Best for Beginners:

   • Stripe – Great for online businesses and developers

   • Square – Ideal for both in-person and online sales

   • PayPal – Easy setup, widely trusted

   • Nationwide Payment Systems (NPS) – Great for small businesses with flexible options: recurring billing, ACH, invoicing, payment links, POS systems, WooCommerce plugin, and more.

   Look for:

   • Transparent pricing (Flat rate, Cost Plus, Surcharge, Dual Pricing)

   • Good customer support (phone + email)

   • Easy integration with your website or tools

   • Built-in fraud protection

   ---

    Step 3: Decide If You Need a Payment Gateway

   A payment gateway is the digital guard that encrypts and transmits your customer’s payment securely.

   Some processors (like Stripe or Square) include a gateway. Others (like banks) may require a separate one.

   You might need a separate gateway if:

   • You’re using a custom website

   • You want to use your own merchant account

   • You need features like subscriptions or multi-currency support

   Top Gateways:

   • Authorize.net

   • NMI

   • NPS ONE

    Step 4: Choose an E-Commerce Platform or Invoicing Tool

   Now decide how you’ll accept payments—through a website or by sending invoices.

    Option 1: E-Commerce Platforms (For Selling Products or Services)

   Use these if you’re selling online:

   • Shopify – All-in-one and beginner-friendly

   • Wix – Drag-and-drop, easy to use

   • Squarespace – Stylish templates, simple store setup

   • WooCommerce – Flexible for WordPress users (NPS offers a free plugin)

    Option 2: Invoicing Tools (For Services & Freelancers)

   Perfect if you’re offering services like coaching, design, or consulting:

   • QuickBooks Online

   • NPS ONE and Clickbillr – Both integrate with QuickBooks and support “Pay Now” invoice links

   Pro Tip: Make sure your platform and processor integrate smoothly—this saves time and accounting headaches.

    Step 5: Apply for a Merchant Account

   A merchant account is a special bank account that holds card payments before transferring them to your business bank account.

   Stripe, Square, and PayPal include this by default, but having a dedicated merchant account (like from NPS) can offer:

   •  Faster deposits (even same-day)

   •  Better reporting tools

   •  More control + fraud protection

   •  Potential for lower fees as you grow

   You’ll need:

   • Business license & EIN

   • Voided check or bank paperwork

   • Monthly sales estimates

   • Possibly your personal credit info

    Step 6: Set Up and Test Your Checkout System

   Now it’s time to create your checkout or payment flow.

   Checklist:

   •  Connect your payment processor to your website or app

   •  Customize checkout with your logo, colors, and secure icons

   •  Enable multiple payment options (cards, Apple Pay, etc.)

   •  Set up email receipts and notifications

   •  Add tax/shipping calculators if needed

   Test it:

   • Make test payments

   • Try different devices (mobile, tablet, desktop)

   • Make sure money lands in your dashboard

   First impressions matter—make checkout seamless.

   STEP 7: SECURE YOUR WEBSITE

   Security isn’t optional—protect your business and your customers.

   MUST-HAVES:

   • SSL Certificate (your site should show https://)

   • PCI Compliance (most processors help with this)

   • Data encryption

   • Fraud detection tools

   • Two-factor authentication

   • Chargeback prevention tools (Ethoca, RDR, CDRN)
