What is the biggest mistake small businesses make when setting up an online store?

The single most expensive mistake is launching a store before the conversion path has been tested by a real person on a real phone. It doesn’t matter how good your products are if the shipping cost appears for the first time at checkout, the buy button doesn’t work on Safari, or there’s nothing near the “Add to Cart” button that gives a first-time visitor a reason to trust you. These aren’t polish issues — they’re revenue leaks that start losing customers from hour one.

The Most Common Conversion-Path Failures

• Hidden shipping costs at checkout. Shoppers abandon carts at extraordinarily high rates when the shipping cost appears for the first time at the payment step. Show shipping estimates on product pages or at minimum on the cart page — not as a surprise at checkout.
• A checkout that breaks on mobile. Most Texas shoppers are buying on their phones. If your checkout flow has a form field that’s hard to tap, a payment button that’s off-screen, or a confirmation page that doesn’t load — you’re losing those sales with no visibility into why.
• No trust signals near the buy button. A first-time visitor to your store has never bought from you before. They need to see something — return policy, secure checkout badge, a short customer review — within visual range of the purchase action. Hiding this information in the footer doesn’t count.
• Out-of-stock products with no alternative. Sending a customer to a dead-end product page with no suggestion of what to buy instead ends the session. Configure related product recommendations and out-of-stock behavior before launch.
• No confirmation email. If a customer completes a purchase and doesn’t receive an order confirmation within minutes, they’ll assume something went wrong and call their bank. Test the full transactional email sequence before going live.

Pre-Launch QA Checklist

• Complete a test purchase on iOS Safari and Android Chrome.
• Verify shipping rates display before checkout.
• Confirm order confirmation emails fire correctly.
• Check that trust signals (return policy, secure payment, reviews) are visible on product pages and at checkout.
• Test every payment method you’ve enabled — not just one.

Our e-commerce builds go through this QA process before any store launches. Let’s talk if you want a store built to convert from day one.
