One family, five inboxes: how to keep household receipts in one place

Count the email addresses your household's receipts arrive at. Two personal accounts each, maybe an old Yahoo that still gets the electricity bill, the address the school portal insists on, the one attached to the App Store family account. Five is typical; some households clear eight. Every receipt lands wherever the vendor happened to be told, and eight months later "who has the email for the washing machine?" is a genuine research project.

Receipt apps mostly ignore this because they're built for one person or for companies. But the household is the natural unit for receipts — one budget, shared appliances, kids' costs that belong to everyone — so the system should be built household-first. Here's the shape that works.

One library, fed from every inbox

The core move: pick one shared receipt account, then plumb every family address into it. There are two pipes, and you can mix them per inbox:

• Connect the busy inboxes. The one or two accounts where most receipts land are worth connecting directly — Gmail via read-only OAuth, iCloud/Yahoo/Fastmail via IMAP. Connected inboxes backfill history (up to 12 months on first import) and pick up new receipts automatically, so the bulk of the household archive builds itself on day one.
• Forward from the rest. Every account gets a personal forwarding address ([email protected]). For the low-traffic inboxes — the old Yahoo, the school-portal address — set a forwarding rule pointing at it, or just forward the odd receipt manually. A partner who'd rather not connect their inbox at all can participate entirely through forwarding; nothing reads their mail, and only what they send over leaves it.

Paper receipts — school uniform shop, the market, the vet — are one photo from whoever's phone is closest, uploaded to the same place.

Whose receipt is it? Usually the wrong question

Most of the time "whose" doesn't matter: what the household actually asks is did we already pay this, what did the term's swimming lessons cost, where's the proof of purchase for the fridge. A single shared library answers those in one search precisely because it doesn't partition by person.

The exception is tax. Deductions belong to the individual who incurred them, so two earners means two returns drawing on one archive. The fix is a two-second habit, not a second account: tag each deductible receipt with a name (alex, sam) as it lands. At tax time, filter by tag and each person gets their own deductible subset out of the shared pool — the approach one of our households described in family receipt sharing, as we actually do it.

Categories that match how families spend

Household categories earn their keep when they answer real questions: Kids — school, Kids — activities, Medical, Home & appliances, Groceries, plus each earner's work-deduction categories. That's enough to see term-by-term school costs, pull every medical receipt for a health-fund claim, or produce the warranty receipt for any appliance in the house. Resist granularity beyond what you'll query — small lists survive.

What this costs

Nothing extra, is the point. The Paper Keep has no per-user pricing and no per-inbox pricing — one subscription ($3/month) covers however many inboxes the household plumbs in. Corporate expense tools charge per seat because companies have seats; a family has a junk drawer, and the pricing should match.

The one rule that keeps it working

Route everything into the library and never try to maintain a parallel system on the side — no separate folder of "important ones", no second spreadsheet. One place, every receipt, each person tagging their own deductibles. The households this works for aren't the organised ones; they're the ones who removed every decision except "tag it if you'll claim it".
