The post-purchase problem nobody builds for: receipts, serials, and warranties

Everyone optimizes the buying experience. Almost nobody builds for what happens after checkout.

Every appliance, device, and tool you buy comes with records that matter later: the receipt, purchase date, model number, serial number, the manual, and the warranty terms. Most people have no system for keeping those together — they're scattered across email, a kitchen drawer, screenshots, and random cloud folders. So when something breaks, the warranty claim dies on a single question: "Can you send proof of purchase and the serial number?"

That's the gap we're building SnapRegisters for.

The simple version of the fix (works with any notes app)

The day anything substantial arrives, capture four things:

The product
The receipt
The model / serial label (it fades — grab it early)
The warranty card or manual

Organize them by product, not by document. Instead of "where's that receipt," it becomes "open the dishwasher record." When support asks for details, it's a 10-second lookup instead of a 20-minute hunt.

Where AI actually helps after the purchase

The interesting part for builders: the post-purchase layer is a great fit for AI. Point a camera at a receipt and you can extract the model, serial number, and purchase date, then track the warranty automatically — turning a tedious filing chore into a 5-second snap. It's not flashy AI, but it's the kind that quietly saves people money (most warranty coverage goes unused simply because the paperwork is gone).

If you've ever eaten a repair bill for something that was technically still covered, you've felt this problem. Curious how other builders think about the "boring but valuable" software gaps like this one.
