Post your whole inventory to Facebook Marketplace in seconds
Listing a vehicle on Facebook Marketplace by hand takes minutes of retyping and photo uploads. MarketSync's Chrome extension fills the entire listing for you — you just click Post.
What is the MarketSync auto-poster?
MarketSync is a Chrome extension and dashboard that lets car dealers and sales reps post their inventory to Facebook Marketplace fast. Pick a vehicle, click Post, and the extension opens the Marketplace listing form and fills in the year, make, model, price, mileage, colours and body style, uploads the photos in order, and pastes a clean description. A listing that used to take several minutes now takes seconds — and you still click the final Post button yourself.
How it works
Install the extension
Add the MarketSync Chrome extension and sign in. Your synced inventory appears in a side panel.
Pick a vehicle
Choose any vehicle from your inventory and click Post. The extension opens the Marketplace form.
Auto-fill & post
Every field and photo fills in automatically with a live progress bar. Review, then click Post.
What you get
Seconds, not minutes
Fills every field and uploads photos automatically so a rep can list dozens of cars in the time it used to take for a handful.
Side-panel workflow
The extension docks beside Marketplace so you can see your inventory while you post, like Market Post Pro but broader.
Photos in order
Drops your vehicle photos into the listing in the right sequence — no manual drag-and-drop.
Account-safe
You post on your own account and click Post yourself, with built-in posting-safety limits to keep your cadence natural.
