For eBay resellers

Strooply

An AI listing and profit-tracking app for people who sell on eBay. Take a photo of an item and Strooply tells you what it is, what it sells for, and drafts the listing. When it sells, Strooply works out what you actually made after every fee.

Why we built it

Strooply started as a tool for our own eBay store. Sourcing at thrift stores and estate sales was the fun part. The hours afterward spent looking up comps, typing titles and item specifics, and reconciling fees in a spreadsheet were not.

So we built the app we wanted: point a phone at an item, get a real answer on what it sells for, and have a draft listing waiting by the time we got home. Every feature was used on our own inventory before it shipped. In our store, the time from scan to published listing dropped from roughly 10–20 minutes to about 90 seconds.

How it works

Three steps, from the shelf to sold.

  1. Snap or scan

    Take a photo or scan a barcode. AI identifies the brand, model and visible condition, so there's nothing to type.

  2. Check the numbers

    See live eBay comps, up to six months of sold history, sell-through rate and an estimated net profit before you decide to buy.

  3. Publish and track

    Save a draft on the spot, add photos at home, and publish with a tap. Profit is tracked automatically when the item sells.

Features

Everything a reseller needs from sourcing to tax time, in one synced account.

AI listing generator

Turns a photo into a draft with title, description, category, item specifics and a shipping estimate. You review every field before it goes live.

Sold comps & pricing

Live listings plus sold history, median sold price, sell-through and time-to-sell, so pricing is based on what actually sold.

True net profit

Pulls final value fees, promoted listing costs, shipping and refunds from eBay's own records and subtracts your cost of goods.

Barcode & bulk scanning

Scan books, media, games and hardware at the shelf. Queue up to 10 barcodes and send them to drafts together.

Inventory management

SKUs, storage bins and locations, lot purchases split across units, and aging reports that show what's been sitting too long.

Receipts & tax summary

Photograph a receipt, link its lines to items, and export a tax summary for your records. It isn't tax advice.

Sourcing trips & ROI

Group stops into trips, log mileage, and see which sources (thrift, estate sales, yard sales) earn the best return.

Teams

Pro and Team plans add seats for helpers, each with their own role, so your whole operation works from one account.

Free reseller calculators

eBay fee, max buy price, sell-through, mileage and store break-even calculators, free to use without an account.

Who it's for

Strooply is designed around how resellers actually source and sell.

Thrift store flippers

Quick, phone-first research in the aisle so you know what's worth buying before you reach the register.

Estate sale buyers

Barcode and bulk scanning, lot cost allocation, and multi-category drafting for big hauls.

Full-time sellers

Profit analytics, source ROI, inventory aging and team seats for an established store.

Safe for your eBay account

Strooply connects through eBay's official developer APIs using OAuth, so your eBay password is never shared with us. Access tokens are encrypted, and you can revoke access at any time from your eBay account settings.

Nothing is published without your approval. AI drafts the listing, but you review and confirm every one before it goes live. There's no scraping and no bots.

Frequently asked questions

Do I need an eBay account to use Strooply?

Not for research or saving drafts. You'll connect your eBay account when you want to publish listings and sync sales, fees and payouts.

How does Strooply identify items?

It uses Google Gemini, through Google Cloud's enterprise Vertex AI service, to read the photo for brand, model, size and condition, then matches it to eBay listings. Common items like electronics, sneakers and clothing identify well. Obscure or handmade items may need a quick title edit.

Where does the pricing data come from?

Live eBay listings plus up to six months of sold history. When there are no recent sales, Strooply shows an AI estimate and clearly labels it as one.

Which fees are included in net profit?

Final value fees, promoted listing costs, actual shipping versus what the buyer paid, and refunds or return costs, all taken from eBay's Finances API.

Can Strooply publish listings on its own?

No. Every listing is a draft until you review and confirm it.

Who makes Strooply?

Strooply is built and operated by The Stroop LLC, a Washington software company. Questions go to zach@strooply.com.
