CrossOff: Crosslister & Auto Delister for Resellers

Inventory and crosslisting for resellers: list an item once, post it to your selling sites, and take the rest down when it sells.

Post it everywhere. Sell it once. CrossOff is inventory and crosslisting for resellers and estate sellers. Add an item once (AI can write the listing from your photos), post it to the marketplaces you sell on, and when it sells anywhere, CrossOff removes your other listings so you never sell the same thing twice. HOW IT WORKS 1. Create a free CrossOff account at crossoffai.com 2. Add items with photos, or import your existing listings or a spreadsheet 3. Add this extension, then open CrossOff → Setup in Chrome: it connects by itself 4. Select items → Post to… → Start posting. When something sells, the other listings come down. WHAT THIS EXTENSION DOES - Posting: opens a marketplace's sell page and fills in your item's title, description, price and photos. You review it and click List yourself. On marketplaces that support it, you can turn on Publish for me to finish the listing too, slowly and one at a time, only when every field is filled in. - Removes your own listings after an item sells elsewhere, in your logged-in Chrome - Imports your existing listings into your CrossOff inventory - Inbox: gathers buyer messages from the marketplaces you choose into one CrossOff Inbox, with phone notifications. When you reply from CrossOff, it opens the chat with your reply typed in; you press Send. - Works slowly, with pauses between actions, and stops if it can't find exactly one matching listing - Shows every post, removal and result in CrossOff, so nothing happens silently WHAT IT DOESN'T DO - It never sends a message for you - It doesn't read other people's listings or your browsing history - It only runs on CrossOff and supported marketplace pages - It never sees your marketplace passwords CROSSOFF ALSO GIVES YOU - Inventory with up to 12 photos per item, storage spots, quantity, brand, size and condition - Listing age on every item, with stale listings flagged at 90 days - Cash and in-person sales with one tap - Revenue, fees and profit by month and platform, plus CSV export Free for up to 25 items. Unlimited items and the Inbox from $14.99 CAD a month. The full list of supported marketplaces is at crossoffai.com. Some marketplaces don't offer seller APIs, and automating their pages isn't something they officially allow. Using the extension is your choice; CrossOff also works without it. CrossOff isn't affiliated with or endorsed by any marketplace.
