How to Start Accepting Card Payments: Complete Small Business Guide

If you are still cash-only, every card-preferring customer who walks out is lost revenue. Setting up card acceptance is faster and cheaper than most owners think. This guide walks you from zero to taking your first card payment.

Step 1: Choose a Processor

Decide between flat-rate (Square, Stripe — simple, predictable, best under ~$10k/month) and interchange-plus (Helcim, Stax — cheaper at higher volume). For a brand-new business, start flat-rate; revisit when volume grows.

Step 2: Decide In-Person, Online, or Both

In-person needs a reader or register. Online needs a payment gateway and a checkout page. Many processors do both from one account, which simplifies reconciliation.

Step 3: Get Your Hardware

For a counter, an all-in-one register is the least-hassle path. For a service business on the move, a mobile reader paired to a phone is enough to start.

Step 4: Set Up a Receipt Printer and Drawer

Even card-first businesses need a receipt printer and a cash drawer for change, tips, and the occasional cash sale.

Step 5: Understand the Fees

Expect roughly 2.6%–2.9% plus a fixed per-transaction fee on flat-rate plans. Watch for monthly minimums, PCI fees, and statement fees — read the fee schedule before signing.

Step 6: Stay PCI Compliant

Use your processor's compliant hardware and never store full card numbers yourself. Most modern readers handle compliance for you.
