Cross-Listers, Inventory Apps, or a Spreadsheet: What Actually Finds Your Stock?

Ask a reselling group how to manage your inventory and you'll get three answers: get a cross-lister, get an inventory app, or "honestly, a spreadsheet is fine." All three are reasonable advice. All three are also answering a different question to the one that costs you money, which is: when an item sells, can you walk straight to it?

Here's what each option actually does, where it's genuinely good, and the gap in the middle.

Cross-listers (Vendoo, List Perfectly, Crosslist)

Cross-listers solve the listing problem: write once, post to eBay, Poshmark, Depop, and the rest, then de-list everywhere when something sells. If you list in volume across several marketplaces, they earn their subscription.

What they don't do is care where the item physically is. Your listing lives in the cloud; the jumper lives in one of eleven tubs in the garage. When it sells, the cross-lister's job ends and your dig through the tubs begins. That's not a criticism, it's just not the job they were built for.

Good at: getting stock listed on more marketplaces, faster. No help with: finding the item after it sells.

Generic inventory apps (Sortly and friends)

General-purpose inventory apps are built for tracking stuff in locations: warehouses, tool cribs, office assets. Some, like Sortly, are genuinely pleasant to use, with folders, photos, and QR labels.

The catch for resellers is that they don't know what a listing is. There's no concept of "this bin has 14 items listed on eBay and 6 still waiting." You end up maintaining a parallel universe: your marketplace knows what's for sale, your inventory app knows where things are, and you're the sync layer between them, manually, forever.

Good at: general "what's in this box" tracking with tidy labels. No help with: anything to do with your listings or sales.

The spreadsheet

Free, flexible, and always there. A disciplined reseller with a simple system can genuinely run on a spreadsheet for a while, and plenty do.

The problems are the ones every spreadsheet has: it's only as accurate as your last manual update, it doesn't scan anything, it can't print labels, it doesn't know your listings exist, and on your phone in a cold garage it's a pinch-zoom nightmare. It also fails silently: the row says tub 7, the item left tub 7 two months ago, and nobody told the spreadsheet.

Good at: starting out, zero cost, total flexibility. No help with: staying accurate once the pile gets serious.

The gap in the middle

Line them up and the pattern is obvious:

	Deathpile	Cross-listers	Generic inventory apps	A spreadsheet
Knows which tub every item lives in	✅	❌	partial	manual
Mobile pick lists with scan-confirmed dispatch	✅	❌	❌	❌
Reads your real eBay and Shopify listings	✅	partial	❌	❌
QR labels for items and storage	✅	❌	partial	❌
Built for resellers specifically	✅	✅	❌	❌
Cross-posts listings to marketplaces	❌ by design	✅	❌	❌

Notice the last row. Deathpile deliberately doesn't cross-post, that's what cross-listers are for, and a good one is worth keeping. Deathpile owns the column the others skip: every item tied to a tub, a shelf, and its listing, with QR labels and scan-confirmed picking so the right item goes out the door every time.

So what should you actually run?

• Low volume, one marketplace, tidy spare room: a spreadsheet is fine. Come back when finding things starts costing you time or refunds.
• High volume across several marketplaces: a cross-lister for listing, plus something that tracks physical location, they solve different problems and stack well.
• The pile has outgrown your memory: that's the exact problem Deathpile was built for. Give every item a home, print the labels, and let a sale become a two minute pick instead of a twenty minute dig.

The tool that lists your stock and the tool that finds your stock don't have to be the same tool. But the second one is the one that stops you refunding a sale because the item is somewhere in the garage.
