Open the Toolkit page

In Google Chrome, go to sellerio.in/q/toolkit — that link opens the Toolkit's page directly.

Prefer to find it yourself? Open sellerio.in, scroll down to Free Chrome Extensions, and take the first of the three cards — Sellerio Seller Toolkit.

The Free Chrome Extensions section on sellerio.in — all three cards, with Sellerio Seller Toolkit on the left.

Full section width · light theme

It must be Google ChromeThe Toolkit installs from the Chrome Web Store. Edge, Brave and other Chromium browsers accept Web Store extensions too, but Chrome is what it is tested on.

Click Add to Chrome

Click the blue Add to Chrome button on the Toolkit card. The Chrome Web Store opens in a new tab.

Check you have landed on the right listing: Sellerio — Seller Toolkit for Amazon, Seller Flex, Flipkart & Meesho, published by sellerio.in. Then click Add to Chrome at the top right of that page.

SHOT 02

The Chrome Web Store listing header — the extension name, the sellerio.in publisher line, the rating, and the blue Add to Chrome button.

Include the address bar so the store URL is visible

Click Add extension

Chrome asks you to confirm. Click Add extension.

The box says "Read and change your data on a number of websites". That is Chrome's own summary wording, and it is the same sentence it shows for every extension that works inside a website. Click Show Details to see the actual list.

SHOT 03

Chrome's Add "Sellerio — Seller Toolkit…"? confirmation box, showing Show Details and the Add extension button.

Crop tight to the dialog

What that list actually containsfour seller panels — Seller Central, Seller Flex, the Flipkart Seller Hub and the Meesho Supplier Panel — plus the storage addresses your marketplaces serve label PDFs from, and Sellerio's own account server. There is no permission to read every site, and none to read your browsing history.

Why those storage addresses are neededFlipkart and Meesho hand out label PDFs from Google Cloud links, and Amazon from its own storage addresses. To crop the file you just asked for, the Toolkit has to be allowed to read it — and it only ever reads the file your marketplace has just given you.

A tab opens by itself

Nothing to click. The moment the Toolkit installs, it opens its own tab: Welcome to Sellerio.

Choose Create FREE Sellerio account if this is your first Sellerio account, or Sign in to your Sellerio account if you already have one.

Already use Sellerio Autofill or Insights? You will not see this tab at allThe Toolkit finds the sign-in you already have in this browser and uses it.

Create your free account

Fastest way: click Continue with Google. Or fill in your name, email and a password and click Create account.

Mobile is optional. Nothing is charged and you are not asked for a card.

This is not your marketplace passwordSellerio never asks for your Amazon, Flipkart or Meesho login and never sees it. The Toolkit works inside the seller session you are already signed in to, in your own browser.

It signs you in and closes

You are signed in straight away, and the tab closes by itself. Nothing left to do.

Your settings, saved SKU sizes and saved boxes now follow this account to any computer you sign in on.

Pin it to your toolbar

Click the puzzle-piece icon in Chrome's toolbar, find Sellerio — Seller Toolkit, and click the pin beside it.

Every setting, the label side panel and both data pages open from this icon. Pin it now and it stays on your toolbar.

SHOT 07

07_pin_extension.png

Chrome's Extensions menu open, with Sellerio — Seller Toolkit listed and the Pin tooltip showing.

Crop to the toolbar and the open menu

"No access needed" is the right answer hereChrome groups the Toolkit under No access needed on any page that is not one of the four seller panels — it genuinely has nothing to do on this site. Open Amazon Seller Central and it moves into the active group.

Open the toolbar menu

Click the Sellerio icon you just pinned.

Everything is already switched on. Auto-crop labels on download and Print automatically are on, labels are sorted SKU-wise, and every label gets a sequence number. You can change any of it — nothing here needs setting up before your first print.

Turn on notifications

In the popup, click Turn on beside the notifications line, then Allow when Chrome asks.

This is how you find out what a scheduled run did while you were away from the screen. Only what the Toolkit does by itself is ever shown — never a label, an order, or a customer's details.

Bring your SKU list in from Amazon

Press Import SKUs on the setup checklist. Amazon's Manage Products opens with a small Sellerio panel on it — press Export SKUs there.

Every SKU you sell lands in the Pickup Builder, however many pages your catalogue takes, with the product name beside each one. You type no codes at all. The rows arrive empty: the weight and the box are what you fill in next.

SHOT 24

Crop to the panel, bottom-left of the page

Do it again whenever you add productsIt adds the new ones and refreshes the product names, and it never touches a weight, a box size or a name you typed yourself.

Prefer a spreadsheet? Download template gives you the same list as Excel or CSV with the SKU column already filled — type the weights there and import it back.

Save each SKU's size — once, ever

In the Pickup Builder, type the weight and the three box measurements into each row. There is no Save button — each box saves as you leave it.

One row per SKU: weight, length, width, height. Saved to your account and reused on every run. Already have them in a sheet? Import Excel or CSV takes any file with a SKU column and those four numbers. Starting from nothing? Download template, fill it in, import it back.

SHOT 20

The Easy Ship — dimensions & weight page with a real SKU table filled in.

Needs an account with saved sizes · blur nothing, SKUs are fine

Nothing is saved until you say soAn import shows you what it read — how many rows, and which units it thinks the file is in — and waits for Save to my account. There is an Undo that after it, too.

Working in kilograms or inches? Change Weight in and Sizes in at the top and type in the unit you actually use.

Name a SKU in your own words

Read the Title column, then type what your team calls it into My SKU. That is what gets printed on the label instead of Amazon's code.

Amazon gives some listings a code like QG-0A83-W6EP, which tells a packer at a shelf nothing. The title column is there for exactly this moment — it says what the thing actually is, so you can name it without opening the listing. Leave My SKU blank and Amazon's own SKU prints, as before.

Keep it short — up to 30 charactersIt has to stay readable printed on a label. The gear at the end of the toolbar switches the Title and My SKU columns off if they are in your way, and any column can be dragged wider to read a long title in full.

Press Run: Schedule Orders → Print

On Seller Central, pick your day — Ship by today, Ship by tomorrow or All unshipped — and press Run: Schedule Orders → Print on the Sellerio card.

From that one press it requests the FBM Unshipped Orders report, waits for Amazon to make it ready, fills every parcel from your saved sizes, uploads the file to Schedule Pickup, and downloads the labels.

SHOT 21

The Sellerio card on the Seller Central orders page — the day segment, the order count, and the Run: Schedule Orders → Print button.

Blur buyer names and addresses

Amazon allows one orders-report request every four hoursIf you have just pulled a report by hand, the run waits for that window.

It stops rather than guess

If a SKU is not ready, the run pauses on the card and names it. Type what it asks for, then continue.

A parcel needs all four numbers — weight, length, width and height. A row with a weight and no box is not a parcel, and it stops just the same as a SKU it has never seen. So does an order for two or more of the same thing, the first time: it asks whether that goes in one bigger box, and remembers your answer for that SKU at that quantity.

This is deliberate and it is worth knowing why. Easy Ship reweighs your parcel at pickup and bills you the difference, so a guessed weight is money out of your account on every order until you notice — and a pattern of under-declaring is an account-health problem. So an order whose SKU has no saved package is blocked and named, never filled in with something plausible and never quietly dropped.

SHOT 22

22_easyship_pause.png

The card paused mid-run, naming the SKU it has no size for.

Stage a SKU with no saved size to produce this

There is deliberately no "default weight for unknown SKUs" settingIt would be used once and then forgotten, which is the failure mode dressed up as a convenience.

Check it, then it uploads

Before anything goes to Amazon you see every order — weight, box, count. Nothing is uploaded unseen.

Then the labels download, each cropped to 4×6 with the SKU and quantity printed on the front. If printing is set up they are already printing.

SHOT 23

23_easyship_review.png

The review list — every order with its weight, box and count, before the upload.

Blur order IDs if you prefer; weights and boxes are the point

Every file you build is kept under Dispatch history on the Easy Ship page, searchable by date and exportable as CSV — with no buyer details in it.

Hold back an order you are not ready to ship

When an order is for more than five units, tick Skip This Order beside it. The rest of the batch goes ahead as normal.

An order for twenty units is not always a sale, and raising a case with Amazon to check the buyer takes days. So a skip stays: every later run leaves that order out — whether you press the button yourself or it runs on a schedule, and whichever day you have selected. It comes back only when you put it back, and the card says how many are waiting so a skip cannot quietly become a forgotten order.

The tick is per order, not per productTwo orders for the same SKU can be held back separately.

Download labels exactly as you always have

Select your orders and press Amazon's own Download labels button — or let the run do it for you.

The Toolkit works under that button. Nothing about your routine changes.

What comes out

The file saves already cropped — and if printing is set up, it is already printing.

• Cropped to 4×6, with the invoice page removed
• The SKU and quantity printed on the front of every label
• Sorted so every label for one SKU comes off together
• Multi-item orders first, each with a large QTY block
• A sequence number in the corner of every label

One finished label, close up — SKU and quantity on the front, sequence number in the corner.

Photograph a printed label flat · blur the buyer address

Why the number mattersif the roll runs out at label 47 of 70, read the last clean number, change the roll, and reprint from 48. Nothing is guessed and nothing is printed twice.

Set up QZ Tray

In the popup, click Set up printing and follow the steps on that page.

Without this, Chrome's print preview opens with your last printer already chosen — one Enter. With it, there is no preview and nothing to click at all. A copy of every file still lands in your Downloads folder either way.

Step 2 is the one people skipGiving QZ Tray Sellerio's certificate is what stops it asking "Allow?" before every single print. Skipping it still works — you just answer that box every time.

Pick two printersone for label files — your 4×6 thermal printer, or an A4 printer if you print onto sticker sheets — and one for the Seller Flex pick list, which is A4. There is a Test print beside each so you can be sure before a real batch.

Set a daily time

On the Sellerio card, open ⚙, add a time in IST, and choose what should happen at it. There is no daily run until you add one.

Nothing is set for you — a common choice on Easy Ship is an early-afternoon time with Schedule pickups + labels, for orders shipping today. At that time the Toolkit runs on the open marketplace tab and sends you a notification saying what it did — and what needs you.

The Daily schedule · IST block — a time set, the plan chosen, and the "Next:" line.

Crop to the card

Two honest limitsChrome has to be running for a scheduled time to fire — a closed browser runs nothing, and a run Chrome fires hours late is skipped rather than run at the wrong time. And you must be signed in to the marketplace; the card tells you if you are not.

It stops rather than guessIf a run meets something it cannot decide — a SKU with no saved size, an order with several items — it pauses on the card and asks. It never invents a weight or a box.

If a page ever asks you to prove you are human

Nothing to do. Everything automatic on that marketplace stops until you press something yourself.

A page showing a security check, reloaded every fifteen minutes all day, is how a seller's account gets rate-limited and then blocked. So a check puts that one marketplace on hold: no refresh, no auto-accept, no scheduled run. Your own clicks always work, and pressing one clears the hold. Holds are per marketplace — a check on Meesho is no reason to stop working on Flipkart.
