The 5 Most Common Software Bugs That Hurt Small Businesses
Even the smallest bug can cause big headaches for a small business. From lost sales to frustrated customers, these issues often slip through the cracks because teams assume “it won’t happen to us.” But the truth is, most small businesses face the same handful of bugs again and again.
The 5 Most Common Bugs
Here are the top offenders we see hurting small businesses and how to prevent them:
- Login & Authentication Failures
- Customers can’t log in, reset passwords, or access their accounts.
- Action: Always test login, signup, and password reset before every release.
- Broken Checkout or Payment Flows
- Payments fail, carts don’t update, or confirmation emails never arrive.
- Action: Run a “test purchase” with a real credit card (and refund it) before going live.
- Data Entry & Form Errors
- Forms don’t validate properly, leading to missing or corrupted customer data.
- Action: Test forms with both correct and incorrect inputs (e.g., invalid emails, missing fields).
- Integration Failures
- Your CRM, accounting, or email tool stops syncing.
- Action: Schedule regular “integration checks” to confirm data is flowing between systems.
- Mobile Responsiveness Issues
- Features work fine on desktop but break on mobile.
- Action: Test on at least one iPhone and one Android device before release.
Supporting Insight
