A receipt has a short working life and a long list of jobs. It settles a refund argument, starts a warranty clock, and proves a purchase was a business cost. Yet receipts arrive through four separate doors — email, paper, an app store, a courier’s text — and each door leaks them somewhere different.
One folder, one filename pattern
Make a single cloud folder called Receipts, with nothing inside it but year folders: Receipts/2026, Receipts/2025. In Google Drive that is drive.google.com → New → Folder; iCloud Drive and OneDrive work the same way. A single root matters because you should never have to remember which shop a purchase came from — only that receipts live in one place.
Name every file the same way: 2026-03-14_Argos_Wireless-Headphones_89-99.pdf. Date first, because that is how you actually think (“it was around March”); shop second, because that is the word you will type into search; amount third, so you can match a bank line without opening anything. Save PDFs rather than screenshots — a PDF keeps its text layer, so a search for “Argos” or “89.99” finds the document itself, while a screenshot of an order page is unsearchable and blurry the moment anyone prints it.
Catch the email ones before they scroll away
Gmail will collect them if you tell it to. Paste (receipt OR invoice OR “order confirmation” OR “your order”) into the search box, press Enter, then click the filter icon at the right end of the search bar. Choose Create filter, tick “Apply the label” and make one called Receipts, then tick “Never send it to Spam” and “Also apply filter to matching conversations”. Outlook needs the same job done through Settings → Mail → Rules.
Once a month, open that label and download the PDFs that matter — $50 or BDT 5,000 is a sane threshold. On Amazon it is Account & Lists → Your Orders → Invoice → Print → Save as PDF, which gives business buyers a VAT invoice that a plain order email never provides. Apple purchases live at reportaproblem.apple.com, Google Play ones at pay.google.com → Activity → View receipt. Those two are the ones people forget, then need when a subscription renews for a third year.
Thermal paper is a countdown timer
Most till receipts are not ink on paper. They are a heat-sensitive dye coating, and the print fades because the dye reacts to warmth and friction — typically gone inside six to twenty-four months, faster in a glovebox in summer or a wallet pressed against a phone that warms up in a pocket.
The fastest capture method is the one already in your hand. In the Google Drive app: + → Scan, which crops the edges and exports a multi-page PDF. On iPhone, open Notes, tap the camera icon, choose Scan Documents; the Files app does the same trick. Lay the slip on a dark, plain surface, shoot in even daylight with the flash off, and let the app straighten it — flash on thermal paper blows out the faint print entirely.
Never laminate a receipt. The heat of the laminator turns the whole strip black in one pass. Keep paper originals in an envelope with the month written on it, and photograph the serial-number plate of anything expensive on the same day, because a service desk asks for the serial, not the price.
Make the answer appear in twenty seconds
A folder is storage; an index is a tool. Keep one line per purchase in a Google Sheet with six columns: date, shop, item, amount, return-by date, receipt link. Return deadlines differ more than people expect — Amazon allows 30 days from delivery on most items, online orders in the UK and EU carry a 14-day cancellation right, and Costco stretches most electronics to 90 days. Set a calendar reminder for day 25 on anything above your threshold and you stop paying restocking fees by accident.
Read the retailer’s page for two separate policies before you send anything back. “Unwanted” returns are the short window where you cover postage; “faulty” returns usually run longer and the seller pays shipping. Put the RMA number in the filename — 2026-03-14_Argos_RMA-887412.pdf — because that is the reference a chat agent will ask for.
Treat the folder as personal data
A receipt shows your address, the last four digits of a card, and a surprisingly detailed picture of your household. Give the account holding them two-factor authentication, and share single files view-only instead of handing over the parent folder.
Retention rules are shorter than most people assume: the US Internal Revenue Service generally wants three years of supporting records, HM Revenue & Customs five years after the 31 January filing deadline. Past those points, keep only the fridge, the laptop and the boiler receipts.
Then do the January prune: delete anything past its warranty, confirm the current year folder is backed up, and check the filter is still running. Capture is the easy half — the phone scanning routine covers getting a clean PDF, and the inbox cleanup system stops order emails from being buried in the first place. The UK government’s page on accepting returns and giving refunds explains the faulty-versus-unwanted split that decides who pays the postage.
