The whole system is three moves: photograph the receipt the day you buy the thing, note how long the warranty runs, and set a reminder a month before it ends. Thirty seconds per purchase, and you'll never again pay to fix something that was covered.

Why does something this simple need a guide? Because a warranty claim asks you to produce three separate things, usually years apart — and most of us store them in three different places, if anywhere at all.

Why warranties go to waste

To use a warranty, you need:

  1. Proof of purchase — the receipt or order confirmation, showing what you bought, where, and when.
  2. The warranty terms — how long coverage lasts and what it covers, printed on a slip in the box you recycled the same afternoon.
  3. The memory — knowing, on the day the thing breaks, that it might still be covered at all.

Each piece lives somewhere different. The receipt is a fading thermal slip in a junk drawer or an email you can't find. The warranty card went out with the packaging. And the memory — be honest — was never really stored anywhere. So when the washing machine starts making that noise fourteen months in, the default move is to shrug and call a repair service, because checking feels hopeless.

The fix is to capture all three pieces in the same place, at the same moment: the day you buy.

Step 1: photograph the receipt at purchase

Before the receipt leaves your hand — while you're still in the parking lot, if that's what it takes — take a photo of it. Paper receipts, especially thermal ones, fade to blank grey in a year or two, which is often shorter than the warranty they're supposed to prove. A photo doesn't fade.

For online orders, the order confirmation email is your receipt. Screenshot it or save it as a PDF, because "it's somewhere in my email" works right up until the retailer's messages start looking identical in search results.

If you're doing this at any scale, it's worth setting up properly — there's a best way to store receipts digitally, and it's not "in the camera roll between vacation photos." But even the camera roll beats the junk drawer.

While the box is still open, photograph two more things: the warranty card or terms slip, and the serial number on the product itself. Manufacturers often ask for the serial when you file a claim, and reading it off a photo beats pulling the fridge away from the wall.

Step 2: note the warranty period

Now find how long the coverage runs. It's on the warranty slip, on the manufacturer's website, or on the product page where you ordered. Coverage varies a lot — a year is common for electronics and appliances, and some products carry longer coverage on certain components — so check the actual terms rather than guessing.

Then do the one bit of math this system requires: purchase date plus warranty length equals the date that matters. Write that date down with the receipt photo — in the photo's caption, in a note, wherever it will stay attached to the proof.

Two things can stretch that date, and they're worth a minute to check:

  • Extended warranties you bought at the register or registered online. If you paid for one, the paperwork for it is now part of the same bundle — photograph it too.
  • Credit-card warranty extensions. Some cards quietly add extra coverage to items purchased with them. Benefits vary by card and change over time, so check your card's benefits guide — but if yours has this, the receipt you just photographed is exactly what a claim will require.

Step 3: set a reminder near the end

A warranty end date you'll never look at again is trivia, not protection. The useful version is an alert that arrives while you can still act on it.

The manual way (works today, costs nothing):

  1. Open Reminders or Calendar on your iPhone.
  2. Create an entry a month before the warranty end date: "Dishwasher warranty ends March 12 — test everything now."
  3. In the notes, say where the receipt photo lives.

Why a month early? Because that reminder is your cue to give the thing a shakedown. Run the appliance through its paces, check the laptop battery, wiggle the wobbly hinge. Problems found inside the window are free; the same problems three weeks later are a quote from a repair shop. If something big is under warranty and acting up, here's how a claim or return actually goes — it's far less painful when the paperwork is already in hand.

The honest weakness of the manual way: it depends on you doing all three steps, for every purchase, forever. Most people manage it for the fridge and skip it for the headphones — and it's always the headphones that break.

The automatic version

This is precisely the kind of bookkeeping Paperlock is built to delete. Photograph the receipt once and it reads what you bought, where, for how much, and on what date — then files it behind Face ID with a clear title, no naming or folders. When a warranty end date is in play, you get reminders 30 days and 7 days before it expires, with no setup. And on the day something breaks, you don't dig — you ask: "do I have the receipt for the dishwasher?" and the answer comes back with the receipt attached. That's the whole idea of the app, and it's coming soon to iPhone.

Keep the receipt even after the warranty ends

One last habit worth keeping: don't delete receipt photos when coverage runs out. Receipts for big purchases stay useful for insurance claims, resale, and returns long after the warranty is history — there's a longer answer in what documents to keep and for how long, but the short version is that a photo costs you nothing to keep and can be irreplaceable exactly once.

The system, one more time: photograph the receipt today, write down the end date, set the alert. The next time something dies at month eleven of twelve, you'll be the rare person who gets it fixed for free — and gets to feel just a little smug about it.
