Choosing a payment provider can feel bigger than it is. For a first online store, the best option is usually the one that lets customers pay easily, sends money to the right account, supports your business model, and keeps the checkout experience clear.
This guide explains the decision in plain language.
Important: payment providers set their own rules, fees, supported countries, approval requirements, holds, and risk reviews. Always confirm current terms directly with the provider before launch.
What a payment provider does
A payment provider helps you accept money from customers. It usually handles card processing, payment authorization, payout timing, fraud checks, and some dispute workflows.
Your store platform and your payment provider are related but not the same thing. Aegis Commerce can help you build the storefront and guide setup, but the merchant account or connected payment account is what allows the seller to receive funds.
The quick decision
Choose based on how you already sell:
- Use Stripe when you want a clean online card checkout and expect your store to be your main sales channel.
- Use PayPal when your customers already trust PayPal or you want to offer it as an additional familiar payment option.
- Use Square when you also sell in person and want online and point-of-sale activity closer together.
Many sellers eventually use more than one option, but you do not need every payment method on day one.
Stripe: strong for online checkout
Stripe is often a good fit for sellers who want a modern online checkout, card payments, subscriptions, invoices, or platform-connected commerce flows.
Stripe may be a good fit if:
- Your primary checkout is online.
- You want customers to pay by card.
- You need a connected-account model through a platform.
- You may later add subscriptions, deposits, or custom checkout behavior.
Watch for:
- Account verification requirements.
- Payout timing.
- Disputes and chargebacks.
- Product categories that may be restricted.
PayPal: familiar to many customers
PayPal can be helpful when your customers recognize and trust it. It may reduce hesitation for some buyers, especially if they already use a PayPal wallet.
PayPal may be a good fit if:
- Your audience likes PayPal checkout.
- You want a familiar alternative to card entry.
- You sell to customers who prefer wallet-style payments.
Watch for:
- Customer checkout flow differences.
- Holds or reviews for new sellers.
- Buyer dispute expectations.
- How PayPal integrates with your storefront.
Square: useful for in-person and local sellers
Square can be a strong fit for local businesses that already use Square at events, in a shop, or for point-of-sale payments.
Square may be a good fit if:
- You sell both online and in person.
- You already use Square hardware or POS.
- You want local pickup and in-person sales to be part of the same operating flow.
Watch for:
- How product catalog sync works.
- Online checkout options.
- Payout timing.
- Whether the integration supports your store flow.
What to check before deciding
Before connecting payments, confirm:
- Supported country and currency.
- Business type and product category eligibility.
- Transaction fees and payout schedule.
- Refund process.
- Chargeback or dispute process.
- Tax settings and reporting needs.
- Whether you need in-person payments.
- Whether your store platform supports the integration.
Start simple
For a first launch, one reliable payment path is enough. Add more options later if customers ask for them or if your sales channel expands.
A payment setup is successful when the customer can pay, you can receive funds, order notifications are clear, and refund/dispute expectations are understood.
Bottom line
Stripe is often best for online-first checkout, PayPal is useful when customer familiarity matters, and Square is strong for sellers who also operate in person. Choose the provider that fits how you sell now, not every possible way you might sell later.
