PostToMarket Chrome Extension Setup Guide for Dealership Teams

The worst way to roll out a new tool on a sales floor is to announce it at the Monday meeting and expect eleven people to figure it out between ups. By Wednesday, three reps have it working, two have a half-installed extension on a browser profile they never use, one is logging in with someone else's credentials, and the general manager is wondering why only a third of the lot is moving. Software rarely fails on a dealership floor because of the software. It fails because of setup.

This PostToMarket Chrome extension setup guide is written for the person who owns the rollout: the internet director, the used-car manager, or the GM who ended up with the job. It assumes your reps already know how to post to Facebook Marketplace by hand and that you already have a DMS export or a spreadsheet of inventory. What it covers is the sequence that gets a team from zero to a verified first post without shared logins, browser confusion or surprise rework.

The goal is a boring, repeatable setup that every rep completes the same way. Boring is good. It means the first week is spent selling cars, not troubleshooting browsers.

Before You Install: Prepare the Browser and the People

The extension runs in Google Chrome and works with the Facebook session that is signed in on that browser. That single fact drives most of the preparation.

One person, one browser profile, one Facebook identity

Each rep should post from their own Chrome profile, signed into the Facebook account that rep is legitimately authorized to use for Marketplace. Chrome profiles let a single Windows login keep separate sessions, extensions and bookmarks. On a shared desk PC, create one profile per rep rather than letting everyone fall into the same window.

• Do not share a Facebook login between reps. Shared logins are a security risk and create the inconsistent-access patterns that make an account look compromised.
• Do not run the extension in a profile you use for unrelated browsing, extensions or testing.
• Confirm the rep can already open Marketplace and start a vehicle listing manually. If Facebook is asking them to verify identity or complete a prompt, resolve that first.

Decide who owns which role

PostToMarket separates a platform login from a Facebook identity. The dashboard has four roles: admin, manager, sales rep and sales associate. Settle the org chart before invitations go out, so every rep lands in the right queue on day one. If you are not sure how those roles divide up, read Admin, Manager, Sales Rep and Associate Roles Explained before you invite anyone.

Gather a small pilot set of inventory

Pick five to ten vehicles for the first run. Choose units with clean data: a verified VIN, a correct price, current mileage and good photos. A pilot with bad data teaches the team that the tool is the problem when the data is the problem.

Step-by-Step Setup: From Install to Verified First Post

Follow this procedure in order. Resist the urge to skip to posting.

Install and sign in with email

1. Open Google Chrome using the rep's own profile.
2. Install the PostToMarket extension in that Chrome profile.
3. Open the extension and sign in with the same email you use for your PostToMarket dashboard. There are no API keys to copy or paste; sign-in is by email.
4. Confirm that the extension shows you as signed in before moving on.

If sign-in fails, the usual causes are an email typo, a profile that is blocking the extension, or an account that has not been activated yet. Check those three before you contact support at info@posttomarket.com.

Confirm the Facebook session

Open Facebook in the same Chrome profile and confirm you are signed in as the intended person. The extension acts through that session, one vehicle at a time. If a rep is logged in as a different person than expected, listings will go out under the wrong identity, which is the single most expensive setup mistake because it is not obvious until a customer asks why the unit came from another name.

Get inventory into the dashboard

You have three practical ways to populate inventory:

• Bulk CSV or Excel import for a DMS export or spreadsheet, with an import history and a row-level error log to catch bad rows early.
• Capture from auction and wholesale sites to bring units into inventory without retyping them.
• Manual entry for a single unit that arrived this morning.

Every plan supports unlimited vehicles in inventory, so there is no reason to load only a handful of units except for a deliberate pilot. If your export is messy, the pre-posting cleanup steps in Cleaning a DMS Inventory Export Before You Post Anywhere will save you rework.

Review the AI copy and photos

PostToMarket generates a Facebook listing title and description from each vehicle's specs. It is a draft, and it is editable before posting. Read it as you would read copy from a junior associate: confirm that the trim, mileage, price and key features are correct, remove anything you cannot stand behind, and add the detail that only someone who walked the car knows. Use the Facebook photo picker to choose the photos for the listing so the strongest image leads.

Run the verified first post

1. Add one pilot vehicle to your queue.
2. Start posting from the queue and watch the extension complete the listing.
3. Open the listing in Facebook and compare it to the vehicle record: title, price, mileage, description, photos and location.
4. Check that the inventory status moved from draft to posting to posted.
5. Only then queue the rest of the pilot set.

Do not queue the full pilot at once and walk away. The first post is a verification step, not a production run.

Common Setup Mistakes and How to Prevent Them

Most setup problems fall into a handful of patterns. A short checklist at the desk beats a long training deck.

Handling failed posts

A vehicle that lands in the failed status is information, not a catastrophe. Open the unit, read what you can see about the problem, correct the underlying field, and queue it again. If several units fail for the same reason, stop and find the shared cause in your data before you retry the batch.

Keep Facebook behavior in perspective

PostToMarket is an independent tool and is not affiliated with, endorsed by or sponsored by Meta. Marketplace rules and the forms Facebook shows can change, and no tool can guarantee that Facebook will distribute every listing. The practical consequence is that setup is not a one-time event; when something behaves differently on Facebook, re-run the verified first post before you resume normal volume.

Setup Checklist for the Rollout Owner

Print this and tick it off per rep.

• Rep has a dedicated Chrome profile.
• Rep is signed into their own Facebook account and can open Marketplace.
• Extension installed and signed in with the rep's email.
• Rep is assigned the correct dashboard role.
• Pilot vehicles are in inventory with verified VINs, prices and mileage.
• AI titles and descriptions reviewed and edited.
• One vehicle posted, inspected on Facebook and confirmed as posted in the dashboard.
• Rep knows how to mark a vehicle sold from inventory or the queue.

A rep who ticks every box in the first morning is ready for real volume. A rep who cannot tick one of them should not be handed a queue yet.

How PostToMarket Automates This

Setup is a one-time effort, and the product is designed so the ongoing work is not manual. Once the extension is signed in and the Facebook session is confirmed, the heavy lifting moves off the rep.

Posting handled one vehicle at a time

The extension posts to Facebook Marketplace, and also to the rep's Facebook profile and Facebook groups, one vehicle at a time with human-like delays. Daily post limits and delays are enforced on the server, so a rep who is in a hurry cannot accidentally override the pacing the rest of the team follows.

Queues that remove the "what do I post today" question

• A personal posting queue for every rep.
• Managers assign vehicles to associate queues; sales reps self-queue from shared inventory.
• A team queue view where managers can see and release any claim.
• A mobile dashboard that can be installed on a phone's home screen, so a rep can reorder the queue between customers.

Clean inventory in, accurate status out

• Bulk CSV and Excel import, with import history and a row-level error log.
• AI-generated Facebook titles and descriptions that stay editable.
• Inventory statuses: draft, posting, posted, sold and failed.
• Mark as sold and archive from inventory or the queue.

None of this removes the need to review. It removes the repetitive typing and the coordination overhead, which is where dealerships lose the most time.

Roll Out to the Whole Floor in Three Passes

Once the pilot is clean, roll the rest of the team out in passes rather than all at once.

1. Pass one, managers and top reps. They install, post their own units, and find the rough edges in your specific data.
2. Pass two, the rest of the floor. Run a 20-minute desk session: install, sign in, review a draft, post one unit.
3. Pass three, associates. Managers assign vehicles to their queues so they can focus on posting and follow-up rather than deciding what to post.

Schedule a ten-minute check-in at the end of the first week. Ask three questions: what failed, what confused you, and what did you do manually that you expected the tool to handle. Those answers are your next round of training.

Put Your Team on a Setup That Works: Start the 10-Day Free Trial

A rollout that takes a week of back-and-forth is a rollout that your reps quietly abandon. The point of this guide is that a single rep can be signed in, verified and posting inside a morning, and the whole store can follow inside a week.

You can test every step above during the 10-day free trial, with secure Stripe checkout and the freedom to cancel anytime. The Starter plan is $59 per month for a solo seller or independent lot with 1 login. The Dealership plan is $299 per month for a full floor team with up to 13 logins and 2 managers. Unlimited vehicles in inventory are included on both.

Pick the pilot units, assemble the team and start your 10-day free trial. By the end of the trial, your PostToMarket Chrome extension setup should be a checklist your reps can run without you.
