Most developers and vibe coders build their Stripe checkout to accept payments. They don't build it to survive disputes with people, their customers. In Stripe's ecosystem, a single ban or badly handled chargeback can cost your business everything. This article is about how to make sure it doesn't.
Your Refund Policy Is Your First Line of Defence
Before you write a single line of checkout code, you need a refund and chargeback policy. Not a template you copied from the internet. A policy you have actually stress-tested against real scenarios.
For example, I am working on a platform that sells music beats. These fall under digital products. My thought process was: What happens when a customer pays for a beat, downloads it, then says they don't want it anymore and claims they never used it? What if they didn't download it? How would I even prove that? What if they come back after 2 days? 2 weeks? 2 months?
These disputes will come.
Some will be genuine, some will be fraudulent. Your policy is the wall between you keeping that money and Stripe taking it back.
This policy must be visible to the user. The user must accept it before they complete the purchase. The usual feature on most sites is a checkbox with: "I accept and agree to the terms and conditions." Simple. But if it's not there, you have nothing to stand on.
When building, you want to spend more of your initial time in the Stripe Sandbox where you test all of this before real money is involved. Play both God and customer. Simulate every scenario you can think of. Who has access to the payment gateway and at what stage? How are payments reflecting on your dashboard? Don't take the Sandbox for granted because it is the only environment where mistakes cost you nothing.
Capture Every Event. Prove Everything.
When a dispute hits, Stripe doesn't take your word for it. They want evidence. The card provider wants evidence. And if you haven't been recording the right events from the start, you have nothing to give them.
Every interaction between the user and your checkout process needs to be logged. Every click, every purchase, every policy agreement. What IP address did the user have? Was it consistent with their usual IP? Was the purchase made from a valid session? Did the user explicitly agree to the refund policy? Did you deliver the product? You need to be able to prove and demonstrate all of this with timestamps and unique IDs.
This is the part where you have to be deliberate with your AI. If you are vibe coding your checkout, there is a real chance your AI won't build evidence capture unless you specifically ask for it. AI is great at making the payment flow work. AI is not great at thinking about what happens when a customer disputes that payment six weeks later. You have to stress this requirement yourself.
Pro tip: Stripe has an AI Assistant for general queries and Agent Skills and Connectors for deeper integration. Use these if you are on Claude.
Event logging should be built as a feature not an afterthought. You want to be able to export all the evidence Stripe and card providers require, as a PDF or JSON, with all the required fields populated. When the dispute comes, and it will, you pull the file and submit it. That's the difference between keeping the money and losing it.
For reference, look at Stripe's dispute evidence object documentation. It tells you exactly what fields they expect: customer email, customer IP, product description, proof of delivery, refund policy disclosure, and more. Build your logging around that schema and you won't be scrambling when the first chargeback arrives.
Send Receipts and Invoices. Build Trust Before You Need It.
You can configure Stripe to send customer emails in Settings β Business β Email β Customer Emails. This isn't a legal requirement but think about it from the human side. You just made a $240 purchase and you don't get a receipt in your email. That's how distrust starts. That's how chargebacks start.
Receipts, invoices, upcoming deductions, subscription reminders. These are not nice-to-haves. They are evidence that you communicated with your customer. They are proof that the customer knew what they were paying for and when. If a dispute lands, a clean email trail showing receipts sent and subscription reminders delivered tells a very different story from silence.
If you want to go beyond Stripe's default emails and build custom branded ones, a tool like Resend works well for this. You create React template emails, hook them to your Stripe webhooks, and fire a custom receipt whenever a checkout.session.completed event lands. Resend gives you 100 emails a day for free. If you are hitting 100 emails a day, that means you got 100 customers a day and you can afford their $20 a month subscription.
Build For Humans. Defend Against The Worst Ones.
The thread running through this article is that you should build your software for human behaviour. Defend against malicious intent and protect yourself from legal punishment at the same time.
Most startups get burned not because their product was bad but because they didn't think about what happens when a real person with real emotions and real incentives interacts with their payment system. People forget what they bought. People regret purchases. People lie. And some people game the system because they know most small developers don't have their evidence in order.
Your checkout is not just a technical flow. It is a legal document, a communication channel and a defence mechanism. Treat it that way from day one.
