Most home insurance providers recommend keeping a home inventory — a list of what you own, in case you ever need to file a claim after a fire, flood, or burglary. Almost nobody actually has one. The advice is sound; it just sounds like a weekend-long project, so it never starts.

Here's a version that takes about ten minutes, plus five minutes a month after that.

Start with what actually matters

Don't try to catalog every spoon in the kitchen drawer on day one. Walk through your home room by room and note anything that would genuinely hurt to lose: electronics, furniture, jewelry, tools, appliances, anything you'd have to specifically justify to an insurer rather than just "replace it, it was cheap." That's usually 30-60 items for an average home, not 500. You can always add the small stuff later — the goal today is covering yourself for the claim that actually costs money.

A photo beats a description every time

If an adjuster ever asks "prove you owned this," a photo of the actual item sitting in your actual home is worth more than a perfect written description. In Colistor, every item you add can have a photo attached directly to it — so the habit is simple: see something worth listing, take one photo, done. No separate photo folder to cross-reference against a spreadsheet later.

Group it the way you'd actually look for it

A single giant list gets unmanageable fast. Set up a few inventories that match how your home is actually organized — "Living room," "Garage," "Home office" — rather than trying to force everything into one category scheme. When you add something new, you already know which list it belongs in, so there's no filing decision to make later.

Note what you'll actually need later

For each item, jot down whatever detail you'd want on hand if you ever had to describe it to an insurer or just to yourself in six months: roughly what it cost, when you got it, a serial number if it has one. There's no rigid form to fight with — just write it in the description the way you'd actually remember it.

If you live with other people, this is where it gets easier

A home inventory usually lives in one person's head, which means it dies the day that person forgets, or it was never shared with a partner or roommate in the first place. Share the inventory with the people you live with and anyone can add to it, or check it, without you being the single point of failure.

The five-minute monthly top-up

The whole thing falls apart if it's a one-time project you never touch again. Pick one day a month — the day your bank statement lands, or the first Sunday — and spend five minutes adding anything new: a purchase from the last few weeks, something you forgot the first time. Ten minutes to start, five minutes a month to keep it honest, and you have something real to hand an insurer the day you actually need it — not a memory of what you think you owned.
