Key takeaways
- Shopify Payments is the default for many stores, but restricted products, payout holds or unsupported business models can make an external gateway necessary.
- Shopify generally adds its own transaction fee when you use a third-party provider, and some built-in features may not work. Model the full cost before switching.
- Shopify's platform rules and your processor's underwriting both still apply after you switch, so disclose your products and business model accurately.
- Test checkout end to end, set up fraud tools, and plan how you'll handle disputes before you send live traffic through a new gateway.
Most Shopify stores start on Shopify Payments because it is already built in. Some merchants find that it doesn't fit their business, though. Their products may fall outside Shopify's rules, their payouts may get held, or they may need terms tailored to a higher-risk model. That is when a Shopify third-party payment gateway becomes worth a look. This guide covers how payments work on Shopify by default, the common reasons merchants switch, the platform fees and trade-offs to weigh first, and how to connect an external provider without breaking your checkout.
How Payments Work on Shopify by Default
When you open a Shopify store in a country where Shopify Payments is offered, it is usually the default way to accept cards. Shopify bundles the gateway and the merchant account into one setup. You don't sign a separate processing agreement, card payments flow through Shopify's admin, and payouts land in your bank account on Shopify's schedule.
That convenience is real, and it also means a single company controls your storefront, your checkout and your money. A few points matter here:
- Shopify decides what it will process. Shopify Payments has its own list of restricted and prohibited businesses. Being allowed on the Shopify platform doesn't mean you qualify for Shopify Payments.
- Shopify manages risk on its own terms. It can review accounts, delay payouts or hold funds based on its risk assessment.
- Some features are tied to Shopify Payments. Shop Pay and certain accelerated checkout and dispute-management tools generally depend on it. Confirm current availability in your Shopify admin.
If you're unclear on how the pieces fit together, our explainer on payment gateways vs. merchant accounts breaks down who does what in an online transaction.
Reasons Merchants Switch to a Shopify Third-Party Payment Gateway
Plenty of stores never need anything beyond Shopify Payments. For others, the switch is a necessity, and sometimes it's simply the better fit for the business. These are the most common triggers.
Restricted or Regulated Products
Merchants selling CBD, vape products, kratom, nutraceuticals, firearms accessories, adult products and similar categories often find that Shopify Payments won't support them, or that support is limited. These businesses usually need a high-risk merchant account from a processor that underwrites their category directly. Legality varies by state and federal law for many of these products. A gateway switch doesn't change what you're legally allowed to sell or where you can ship it.
Payout Holds, Reserves or Terminations
Shopify may delay payouts or hold funds after a sales spike, a run of chargebacks or a change in what you sell. Dropshippers run into this often because long delivery windows from supplier-shipped orders can drive "item not received" disputes. Some merchants respond by setting up a dedicated merchant account so they have a direct relationship with an underwriter who knows their model. If your account has already been shut down, see our guide on what to do when Shopify Payments is suspended.
An external processor can also apply reserves. The benefit of switching is a direct relationship with the people managing your risk and clearer terms, not freedom from holds. Our guide to rolling reserves for dropshipping stores explains why reserves happen and what tends to help lower them.
Pricing Structure and Volume
Shopify Payments uses flat-rate pricing tied to your plan. As volume grows, some merchants want to compare it against interchange-plus or other pricing models from a dedicated processor. Whether that saves money depends on your card mix, ticket size and the fees involved. See interchange-plus vs. flat-rate pricing for how to compare them honestly.
Location, Currency or Business Structure
Shopify Payments isn't offered in every country, and certain business structures or cross-border setups may not qualify. Stores in that position need Shopify payment alternatives from the start.
Redundancy
Some established stores keep a backup processing relationship so a single account review doesn't stop all sales. This only works if you're fully transparent with every provider about your business. Splitting or routing transactions to dodge one provider's underwriting violates card network rules and can land a merchant on the MATCH list.
A note on compliance: A new gateway isn't a way around Shopify's Acceptable Use Policy or card network rules. Shopify's platform policies still apply to your store whichever processor you use. Your processor will also underwrite your actual products, website and business model. Describe them accurately on your application.
Platform Fees and Other Trade-Offs to Understand
Before you run Shopify without Shopify Payments, model the full cost and the features you'd give up. The main trade-offs:
| Factor | Shopify Payments | Shopify Third-Party Payment Gateway |
|---|---|---|
| Shopify transaction fee | Generally waived | Shopify generally charges an additional fee per transaction, varying by plan |
| Processing fees | Flat rate set by Shopify plan | Set by your processor and gateway; pricing model varies |
| Shop Pay and some accelerated checkouts | Generally available | Often unavailable or limited; confirm in your admin |
| Dispute management | Handled in Shopify admin | Usually handled through your processor's portal |
| Payout timing | Shopify's schedule | Your processor's funding schedule |
| Underwriting | Shopify's risk team | Your processor and sponsor bank |
| Product eligibility | Shopify Payments restrictions apply | Depends on processor's underwriting; Shopify platform rules still apply |
Shopify's added transaction fee and its processing rates change by plan and over time, so check the current figures on your plan's pricing page before you decide.
An Illustrative Cost Check
Illustrative only, using made-up numbers: A store doing steady monthly volume compares its current Shopify Payments cost with a quote from an external processor. The processor's rate looks lower. Once the merchant adds Shopify's third-party transaction fee, the gateway fee and any monthly account fees, the gap shrinks a lot. For this hypothetical store, switching only makes sense because Shopify Payments won't support its product line. Saving money isn't the reason.
Run this math with your own statements. For a benchmark on what online stores typically pay, see our breakdown of ecommerce credit card processing fees.
The Less Obvious Costs
- Conversion impact if Shop Pay or one-tap wallets disappear from checkout.
- Operational overhead from logging into a second portal for disputes, refunds and reporting.
- Reconciliation work when payout timing and reports no longer match Shopify's admin one-to-one.
Checking Compatibility Before You Apply for a Shopify Merchant Account
Shopify doesn't let you plug in just any gateway. It supports a specific set of approved payment providers, and the list varies by country. Check these before you apply anywhere.
- Confirm the gateway is supported in your Shopify region. In your admin, go to the payments settings and review which external providers are available for your store's country. Menu names change, so search Shopify's help center if you can't find the section.
- Confirm the processor will underwrite your business. Ask directly whether it accepts your product category, your fulfillment model (including dropshipping) and your shipping destinations.
- Ask how the integration works. Some providers process payments within Shopify's checkout. Others redirect the customer to an off-site payment page. Redirects can affect conversion and trust.
- Check currency and international needs. If you sell abroad, confirm multi-currency acceptance and settlement options. Our guide to multi-currency pricing covers the margin side.
- Ask about fraud tools. Find out what's included, such as 3-D Secure, AVS and CVV checks, and velocity rules.
- Prepare your documents. Expect to provide business formation details, bank information, processing statements if you have them, and a compliant website with clear refund, shipping and privacy policies. New stores can still apply. See getting a merchant account with no sales history.
MannyPay offers payment gateways including Authorize.net and NMI, along with a Shopify integration and merchant accounts for both low- and high-risk businesses. Approval always depends on underwriting.
Connecting a Gateway to Your Shopify Store
Once you're approved, setup is usually quick. The exact steps depend on the provider and Shopify's current interface.
- Get your credentials. Your processor or gateway gives you the account details or login needed to connect, such as an API login or merchant ID.
- Open payment settings in Shopify. Choose to add a supported third-party provider and pick yours from the list.
- Deactivate Shopify Payments if required. Shopify generally allows only one primary credit card provider at a time, though PayPal and some alternative methods can run alongside it.
- Enter credentials and enable test mode. Use the provider's test or sandbox mode where one is available.
- Run test orders. Try approvals, declines, a refund and a partial refund. Confirm orders show the right payment status in Shopify.
- Go live and watch the first batch. Make sure the first settlements reach your bank account as expected.
Keeping Checkout Smooth After the Switch
A new Shopify external payment provider changes more than where your money goes. Protect the customer experience and your risk profile with these steps:
- Review your payment method lineup. Reorder or hide options so the most-used methods show first. Our walkthrough on reordering payment methods at Shopify checkout shows how.
- Turn on authentication thoughtfully. 3-D Secure can shift fraud liability on authenticated transactions. Badly tuned settings add friction, though. See 3D Secure for online stores.
- Guard against card testing. New checkouts can draw bot attacks. Set velocity limits and use CAPTCHA where your setup supports it.
- Set up a dispute workflow. Because chargebacks will likely move to your processor's portal, decide who checks it and how fast. Dropshippers should keep proof of delivery beyond a tracking number.
- Tell your processor before big promotions. Unexpected spikes can trigger reviews. Our guide on warning your processor about a sales spike explains what to share.
- Watch conversion for a few weeks. Compare checkout completion rates before and after the switch. A drop may point to a redirect, a missing wallet or authentication friction.
Next Steps
A Shopify third-party payment gateway makes the most sense when Shopify Payments can't support your products, your payouts keep getting held, or your business needs a direct underwriting relationship. It usually costs more in platform fees and can remove built-in features. Make the decision with real numbers and an honest look at your risk profile.
