Your first sale can bounce for reasons that have nothing to do with your product. A misconfigured payment gateway, a checkout field that doesn’t match how your customer actually shops, or a tax setting you forgot to touch — any one of these kills a sale silently, and you won’t see it in your analytics as anything other than an abandoned cart.
This is the setup most sellers rush through in ten minutes and then spend their first sales spike quietly fixing under pressure.
If you’ve already worked through How to Start a Shopify Store in 2026 (Complete Beginner’s Guide), this is the section worth slowing down on before you launch—not after.
Shopify Payments vs Third-Party Gateways: Pick the Right One First
Shopify Payments is built in, requires no third-party account setup, and avoids the extra transaction fee Shopify charges when you use an external gateway instead. Unless you’re in a country where Shopify Payments isn’t yet supported, or you have a specific reason to use PayPal or Stripe directly, Shopify Payments is the default that makes sense for almost every new seller.
The extra fee for skipping it — typically 0.5% to 2% depending on your plan — sounds small until you’re running real volume, at which point it quietly becomes one of your biggest line items.
Setting Up Shopify Payments: The Actual Steps
Go to Settings, then Payments, and activate Shopify Payments with your business details—legal name, address, and bank account for payouts. Where sellers get stuck: the bank account name must match your business or personal name exactly as registered, or the verification gets flagged, and payouts stall for days while support sorts it out.
Enter this carefully the first time, because correcting a mismatched bank detail after the fact is slower than doing it right at setup.
Configuring Checkout: The Fields That Actually Matter
Under Settings, then Checkout, you’ll find options that feel minor but shape conversion meaningfully. Turn on account-optional checkout—forcing account creation before purchase is one of the most reliable ways to lose a customer who’s already decided to buy.
Enable Shop Pay if you haven’t already, since one-click checkout measurably reduces cart abandonment for repeat Shopify shoppers who already have it saved. And set your order confirmation and shipping notification emails to actually reflect your brand voice, not the generic default text every new store ships with.
Tax Settings: The Part Sellers Avoid Until It’s Urgent
Since tax obligations vary by where you’re registered and where your customers are, this is worth resolving before launch rather than during your first sales spike. Shopify’s tax settings can auto-calculate based on your nexus locations, but you still need to confirm which states or regions you’re required to collect tax in — that determination is on you, not the platform.
Get this wrong and you’re either overcharging customers (which erodes trust fast) or under-collecting, which becomes your problem to fix retroactively out of pocket.
Abandoned Cart Recovery: Setting It Up Before You Need It
A meaningful percentage of Shopify carts get abandoned before checkout completes—industry estimates commonly run 65-70% across e-commerce broadly. Shopify’s built-in abandoned checkout emails are free and can be activated under Settings, then Checkout, with a simple sequence: one reminder at one hour and a second at twenty-four hours.
This alone recovers sales that would otherwise disappear silently, and it costs nothing to turn on beyond the five minutes it takes to configure the timing.
Testing Your Checkout Like an Actual Customer
Before launch, place a real test order using Shopify’s test payment gateway or a real card you’ll refund immediately. Walk through it on your phone specifically, since most of your traffic will arrive there. How to Choose a Shopify Theme (2026 Guide) affects this experience directly—a theme with a clunky mobile checkout flow will undo good payment configuration underneath it.
If any step feels confusing to you, someone who already knows how the store works, it’ll feel worse to a stranger who doesn’t.
Getting the Full Setup Right the First Time
You can walk through this entire configuration inside a Shopify free trial before you’ve committed to a plan, which is the easiest way to catch mistakes without any live sales on the line.

Ten minutes spent here properly is worth more than the hour you’ll spend troubleshooting a broken payout during your first real sales week.
Payments and checkout aren’t the exciting part of building a store, and that’s exactly why sellers rush through it. Slow down here specifically because it’s the one part of your store where a mistake doesn’t just look bad—it directly costs you money you’ll never see disappear.
