Vendoo polls every 10 minutes. SellDeck uses real-time webhooks. The reliability difference matters when your eBay account is on the line.
Vendoo is a well-known crosslisting tool, but its auto-delist feature is still in BETA, polls your marketplaces every 10 minutes, and requires your computer to be on and connected — and Reddit and Trustpilot have plenty of seller reports of the auto-delist silently failing and triggering oversells. SellDeck takes a fundamentally different approach: real-time webhooks running server-side, sub-minute response, plus a Whatnot-show-aware Lock feature that Vendoo doesn't offer at all. You also get real profit tracking, AI pricing, and tax-ready reports Vendoo doesn't touch.
Server-side webhooks fire within seconds of a sale on any marketplace and fan-out delist jobs in parallel. Vendoo polls every 10 minutes (BETA) and only works when your PC is on — sellers report missed delists and resulting oversells.
SellDeck is the only platform that pauses your eBay and Depop listings before you go live on Whatnot (plus Etsy when you connect your own Etsy app keystring), then lets you restore unsold items with one click. Vendoo cannot do this — it has no concept of live shows.
Listing 5 of an item across marketplaces? SellDeck decrements the remaining quantity on every other marketplace whenever one sells, and only delists when stock hits zero. Safer multi-stock cross-listing.
SellDeck tracks true profit — cost basis, platform fees, shipping, and expenses. Vendoo shows sales data but doesn't calculate your actual margins.
Generate P&L statements, IRS Schedule C reports with automated line mapping, and state-level tax breakdowns. Vendoo doesn't offer any tax reporting.
Upload a photo and get an instant AI price estimate backed by real eBay sold data. Price with confidence.
Plan live shows, generate QR-coded prep sheets, and import Whatnot payouts. Vendoo has no live selling features.
SellDeck starts at $8.99/mo with a free plan. Vendoo starts at $12.49/mo with no free tier and charges per listing on lower plans.

Common questions about SellDeck vs Vendoo.
Yes. Vendoo's auto-delist is still in BETA, polls every 10 minutes, and only works while your computer is on and connected. SellDeck uses real-time webhooks running server-side: sub-minute response, no PC required, with a per-incident audit trail and an oversell recovery inbox if anything ever slips through.
Yes — and Vendoo cannot. SellDeck has a Lock action on every show that pauses your eBay and Depop listings before you go live (plus Etsy when you connect your own Etsy app keystring), then lets you restore unsold items with one click after the show. Items sold mid-show stay sold; only the unsold ones get republished.
For Whatnot sellers and anyone who has been bitten by an oversell — yes. SellDeck has the oversell prevention pipeline Vendoo claims to be working on (BETA), plus full profit tracking, tax reports, AI pricing, and Whatnot show planning Vendoo doesn't do. If your primary need is bulk-crosslisting to 10+ marketplaces, Vendoo may still be useful.
SellDeck syncs listings to eBay and Depop with full oversell-prevention fan-out (auto-delist, multi-quantity sync, show locks). Etsy is supported via a bring-your-own-key path — you create a free Etsy developer app under your own account and SellDeck uses your keystring to sync listings just like the others. It's not a bulk-crosslisting tool like Vendoo, but it handles the entire listing-to-sales-to-protection-to-profit pipeline reliably.
Sellers switch when they get tired of Vendoo's polling-based auto-delist failing them and triggering oversells, or when they realize they need more than crosslisting — real profit tracking, tax reports, and live-show protection. SellDeck fills all of that at a lower price point.
