User guide

Everything you need to use BackToFirst, from installation to automatic rules.

Install and activate

Open the BackToFirst page on the Chrome Web Store and press Add to Chrome. It works the same way on Edge, Brave and Opera.
Start the free trial from the pricing section. After checkout you see your licence key, which you also receive by email and can always find in your account.
Click the BackToFirst icon in the Chrome toolbar to open the dashboard. Go to Settings, paste the licence key and save.

Each licence works on a limited number of browsers (2 with Base, 3 with Pro). If you switch computer, disconnect the old one from your account to free up the slot.

BackToFirst never asks for your Vinted password. It works with the session already open in your browser.

Sync your listings

Open Vinted in a tab and log in as usual. In the dashboard press Sync all the first time: BackToFirst reads your whole wardrobe and stores it in your browser.

From then on the dashboard opens straight away with your archive. Sync only fetches new listings; Sync all, worth running now and then, also updates favourites, views and sold items.

The table shows price, hearts, views, days online, publish date and last action. The orange dot next to the hearts flags items that people like but that have been sitting for more than two weeks. Export CSV downloads the archive for Excel.

Relist

Relisting recreates the listing with the same photos and details, so it shows up among the newest in search again.

Tick the listings you want back at the top.
Press Relist selected and confirm.
For each listing BackToFirst saves a safety copy, deletes the old one and publishes the new one. It waits a few tens of seconds between listings.

If a listing fails to publish, it appears in the To relist box: you can recreate it in one click, download its photos or delete the copy. The draft also stays on Vinted, so you can finish it by hand.

A relisted item is new: favourites and views start from zero. For items with lots of hearts, a price cut usually works better than relisting.

Change prices

Select the listings and choose how to change the price: by percentage, by an amount in euros or to a fixed price. Set a minimum price not to go below and the rounding (whole euro, half euro or ending in .90).

Press Preview to see the old and new price of each listing, then Apply.

Delete listings

Select the listings and press Delete selected. Type DELETE to confirm: deletion is permanent. Sold or reserved items are never touched.

Automatic relisting

In the Automatic relisting tab you choose:

the time of the daily run;
how many listings to relist per run;
the minimum age, for example only items online for more than 14 days;
how many hearts make an item skip relisting.

At the chosen time, if Chrome is open, BackToFirst relists the oldest items and then closes the tab it used.

Automatic offers

Available on the Pro plan, in the Offers tab. There are three modes:

Off: nothing happens.
Simulation: BackToFirst reads your chats and writes in the history what it would do, without sending anything. Recommended for the first few days.
Active: it really carries out the actions.

Offers you receive

For each listing BackToFirst works out a threshold: the highest of the price minus the maximum discount you chose, the listing's Min € (a column in the table) and the minimum price for all listings.

If the offer is at or above the threshold, it is accepted.
If it is lower, BackToFirst makes a counter-offer (for example price minus 5%, never below the threshold) or leaves it to you.
Orders with more than one item are always left to you.

Offers to people who favourite

When someone adds one of your listings to their favourites, BackToFirst sends them an offer with the discount you chose, never below your minimum. One offer per person and listing; people who have already messaged you are left to you.

Accepting an offer cannot be undone: the buyer can pay straight away. Set a Min € on the items you care about and check the history in Simulation before switching to Active.

Improve listings with AI

Available on the Pro plan. Select the listings and press Improve with AI. For each one you see the current text next to the suggestion: title, description and price, with Vinted's suggested price for similar items.

Edit whatever you like, untick the ones you are not happy with and choose Apply changes or Apply and relist. The AI must not add information you did not write: if useful details such as flaws or accessories are missing, it tells you.

Safety and limits

Vinted does not officially approve third-party tools, and using them can lead to account restrictions. To lower the risk, BackToFirst:

works from your browser, with your own session;
waits a random pause between actions;
sticks to a maximum number of actions per day, which you can lower in Settings;
stops by itself if Vinted answers with an access error or too many requests, and only restarts when you unlock it.

If the safety stop appears, open Vinted and check that your account works normally before pressing I have checked, unlock.

Your account and subscription

Go to Log in and enter the email you used to subscribe: you receive a link to log in, no password needed. In your account you can:

see your plan, trial status and next renewal date;
copy your licence key or generate a new one if you think someone else is using it;
see connected devices and disconnect the ones you no longer use;
download your invoices;
change plan, update your payment method or cancel with Manage subscription;
download your data or delete your account.

Common problems

The top bar says "No Vinted tab open"

Open Vinted in a tab, log in and reload the page. Then reopen the dashboard.

Sync cannot find my profile

In Settings enter your user ID: it is the number in your Vinted profile address, for example /member/12345678-name.

The extension says the device limit has been reached

Log in to your account and disconnect a device you no longer use. Devices unused for 30 days free up their slot automatically.

An action stopped halfway

Check the log at the bottom of the dashboard: every error explains what happened. Unfinished relists stay in the To relist box.

Anything else
