Welcome back to NoteLoft Newsletter - the shortcut for founders who want to go from MVP to scale. My goal is to share what actually works when building software, so you can spend more time on deals, growth, and scaling your startup.

If you need help taking your product from MVP to scale, get in touch! We’ve grown our tech team, and we can’t wait to help you.

Let’s get into it!

Every team thinks their software works. Then a user finds a bug in the password reset flow, the one thing everyone swore was "fine"…and suddenly the whole team is in a Slack thread at 11pm trying to figure out why users can’t log into your product.

And to that I say 🚩🚩🚩

Here's the thing: your users are not supposed to be your QA team. But most testing processes are quietly built to confirm things work, not to find where they don't. Those are two very different jobs. If you want to catch the bugs before your users do, here's where to actually look.

1. Test the paths everyone assumes are "too obvious" to break Login. Password resets. Checkout. Cancellations. Permissions. These get skipped in test plans for one reason: everyone assumes they already work. Which is exactly why they're usually the most fragile.

2. Test with bad data, not just clean data Your seed data is well behaved. Your users are not. Missing fields, duplicate records, expired links, weird characters, five-year-old accounts, half-finished profiles; real people don't fill out forms the way your test accounts do.

3. Test what happens when people do things out of order Skip onboarding. Refresh mid-purchase. Click a link from an email three weeks old. Hit back during checkout. Start on a phone, finish on a laptop. Nobody follows the happy path. Nobody.

4. Look for bugs at the handoff between systems This is where it gets interesting. The scariest bugs rarely live inside your app; they live in the seams. Payments. Auth. Email. Analytics. Third-party APIs. Every handoff is a place where two systems that are supposed to work together, break.

5. Test every role as if you are the wrong person Can a regular user see an admin's data? Can staff peek into another customer's account? Permission bugs don't announce themselves. They just sit there, invisible, until exactly the wrong person is able to see something they shouldn’t, or do something they shouldn’t.

6. Simulate failure before failure happens Kill the wifi mid-action. Time out an API call. Reject a payment on purpose. Take a third-party service offline. Failure is coming either way; the only real question is whether your app fails gracefully, or just leaves the user stranded.

7. Review the code behind your highest-risk workflows Testing shows you what's already broken. Code review shows you what's about to be. Especially in payments, migrations, permissions, and anything touching money. One finds today's problem. The other prevents next quarter's.

Your users should not be your first real QA team.

So make sure your engineers find these bugs first!

See you soon,
