Getting started

1. Install the Sellerio Seller Toolkit from the Chrome Web Store.
2. Click the Sellerio icon in Chrome's toolbar and sign in with your Sellerio account. A free account is enough.
3. Open Flipkart Seller Hub, the Meesho Supplier Panel, Amazon Seller Central or Seller Flex. The Sellerio Orders card appears at the bottom-left of the page.

Label auto-crop needs no card at all: click the marketplace's own Print or Download label button and the file that arrives is cropped to the label, ready for a thermal printer. The Orders card presses those same buttons for you.

The Toolkit clicks exactly what you would click, at a human pace, in your own signed-in session. It never calls a marketplace API and never types a weight, box or address it did not read from the page or from your own saved packages.

The Orders card

Settings every card has:

Today, Tomorrow or All — and a day for each daily time

Every Orders card has the same choice: Today, Tomorrow or All — Amazon Easy Ship by ship-by date, Seller Flex by pick-up day, Flipkart by its dispatch-by groups, Meesho by its Dispatch Date column. Today by default. That choice on the card is what the buttons use. Each daily time in the schedule carries its own day too, a small Today / Tomorrow / All under the plan: a 09:00 time can run today's orders and a 13:40 time tomorrow's, and the "Next:" line says which. A new time starts on Today.

Flipkart Seller Hub

Works on Forward Orders and on the Seller Hub home page.

Dispatch by: Today, Tomorrow or All

Forward Orders groups To Accept and To Pack by their dispatch-by time — the pills above the list, "Dispatch by 12 PM, Tomorrow (3)". The card's Dispatch by segment picks which of those a run works: Today the pill for today, Tomorrow the pill for tomorrow, All every pill in turn. Every step — Accept, Print, Mark RTD — selects the pill first and acts on its list only, and the done line says what each day got. Today by default, the same as the other cards; a day with no pill is reported quietly and nothing is clicked. A page without pills is taken whole, as before.

Run all: Accept → Print → RTD

1. Opens To Accept, selects all, presses Accept N Orders, confirms once. Repeats page by page until the tile reads 0.
2. Waits for the accepted orders to reach To Pack, refreshing the page every 10 seconds for up to five minutes, because Flipkart's tiles only move on a page load.
3. Opens To Pack, selects all, presses Print N Labels. The label file is cropped and downloaded.
4. Waits until the cropped file is saved, refreshes once, selects all again and presses Mark N RTD. Turn this last step off with Mark RTD after print.

Accept orders, Print labels and Mark RTD run those steps alone. Stop appears while a run is going and stops it after the current click.

Settings

• Auto-accept — while the tab is open, new orders in To Accept are accepted without a click. Works from the home page too: the card reads New Orders and goes to Forward Orders itself.
• Mark RTD after print — whether Run all marks RTD after the labels print.

A page whose select-all does not take, or a tile that has not moved after a click, is refreshed and tried again (twice at most) before the card reports it. That is Flipkart lagging, not an error.

Meesho Supplier Panel

Works on Orders › Pending, Orders › Ready to Ship and the panel home page.

Dispatch date: Today, Tomorrow or All

Pending and Ready to Ship both show a Dispatch Date/SLA column. With Today or Tomorrow chosen on the card, a run ticks only the rows whose dispatch date is that day — never the header's select-all — accepts them, moves to the next page if the day's rows sit further on, and downloads only that day's labels. All is the header box, as before. Today by default, the same as the other cards. A day with nothing on the page is reported quietly; a page with no Dispatch Date column is taken whole and the status says so.

Run all: Accept → Download labels

1. On Pending, selects all, presses Accept Selected Orders, confirms, and waits for Meesho's Got it, refreshing while Meesho processes.
2. Opens Ready to Ship, sets the filter Label downloaded: No, selects all and presses Label. Waits for Meesho to build the file, refreshing up to eight times, then the cropped labels download.

Labels to get counts only the Ready to Ship orders whose label is not downloaded yet, so a number of 1 means one label, however many orders the tab shows.

Settings

• Auto-accept — new Pending orders are accepted without a click, from the Pending tab or the home page.

Amazon Easy Ship

Works on Manage Orders and on the Seller Central home page, old and new. Two ways to run: from the report (one click, nothing to type once your packages are saved) and from the list (Amazon's own pages, page by page).

Schedule pickups + labels (from the report)

1. Opens Amazon's FBM Unshipped Orders report page, presses Request, and refreshes until the new report is Ready. If Amazon will not build another one yet, the newest report on the page is used and the card says so.
2. Reads the report inside the extension — nothing goes to your Downloads folder — and keeps only what the pickup file needs.
3. Builds the Schedule Pickup file: your saved template (or Amazon's built-in one), your saved package per SKU, weight × quantity, the pickup slot for the day on the card (Today, Tomorrow, All; if today's slots have closed the next day is booked and named).
4. Stops only when it must: a SKU with no saved package — type its weight and L×W×H on the card itself and press Save & continue (it is saved to the Pickup Builder for next time), or open the Pickup Builder, or Skip — and once for multi-item or multi-quantity orders, shown with the summed weight and the largest box (Continue, or Don't stop for these again).
5. Shows you the file before it goes up only when it carries a SKU whose package Sellerio learned by itself and you have not reviewed yet — a package you typed in the Pickup Builder or on the card counts as reviewed, so a run with every package saved goes through without asking. The review lists every order with its SKU, weight and L×W×H, the new SKUs tagged, the pickup day and slot. Upload sends it; Save file keeps a copy; Don't show again for these SKUs is ticked by default, so the next run only asks about SKUs it has not shown you. A copy of every uploaded file is saved to Downloads, and the run is written into the Pickup Builder's history.
6. Uploads the file into the Schedule Pickup box on Amazon's feeds page — never the Shipping Confirmation box — presses Upload, waits until the feed is Done and downloads the labels. More than 500 orders means more than one file, uploaded one after the other.

The Pickup Builder has the same button, Run it on Amazon — that page is now your saved box sizes and this one button; the file is built here, on Seller Central, where you can see it before it goes up. The report and the feed each get ten minutes, refreshed every ten seconds; a day of more than 500 orders goes up as several files, one after the other. From the report: schedule only is a plan for the daily schedule that leaves the labels on Amazon's page.

Or schedule page by page instead (Amazon's own pages)

1. On Easy Ship › Unshipped, sets Amazon's own Ship by date filter to the day chosen on the card — Today, Tomorrow or All — and checks the rows agree (nothing with a later ship-by date). Sets results per page to 100 where the page offers it.
2. Selects every order on the page and presses Schedule pickup(s).
3. On the bulk scheduling page, keeps Amazon's own weight and box for each order. A blank box is filled from the package you saved for that SKU. Then Get Handover Slots and Schedule Orders.
4. Opens the feed page and refreshes every 10 seconds, up to four minutes, until the batch reads Done, then presses Download Shipping Labels. The file is cropped and downloaded.
5. Goes back to the filtered list for the next page — orders it already scheduled are unticked — and repeats until nothing new is listed (at most 20 pages). One sentence and one notification at the end: Done — 3 batches, 240 scheduled, 240 labels downloaded.

Download labels fetches the newest batch's labels on its own. "Schedule only" (no labels) is a choice on the daily schedule rather than a button.

When a weight or box is missing

An order whose box Amazon left blank and whose SKU has no saved package makes the run wait on the bulk scheduling page: the card reads Waiting for you — Sellerio filled 4 of 6; type the weight and box for 2 orders and names them. Type them on the page and press Continue → schedule. Tick Remember what I type and each value you typed is saved as that SKU's package at once (per unit, when Weight × quantity is on), so the next run fills it. A Chrome notification says the run is waiting.

Settings

• Today / Tomorrow / All — which ship-by date a run takes, both ways.
• Auto-schedule + labels — new unshipped orders are scheduled and their labels downloaded without a click, at most once every ten minutes. Off unless you turn it on.
• Fill weight & box automatically — your saved package for a SKU replaces Amazon's weight and box on the scheduling page. On by default. Off: Amazon's numbers stay, and only a blank box is filled from your saved package.

The Pickup Builder learns every scheduling

Whether the fill switch is on or off, the weight and box of every order you schedule are saved to your Pickup Builder for that SKU — a number you typed as your own entry, a number you left as Amazon filled it as one you accepted, and never a number Sellerio filled in itself. Entries for a SKU are kept (the last five) and the saved package is their average, so 340 g · 12×8×6 today and 350 g · 13×8×8 tomorrow settle at 345 g · 12.5×8×7. A two-unit order you scheduled as one parcel is saved as its own entry, "SKU ×2", and used for the next two-unit order of that SKU. After a few days the Pickup Builder holds every SKU you ship, ready for the report run and the list run alike.

Always on, with no switch: a report run stops once to show multi-item and multi-quantity orders; the review card shows for a SKU whose package Sellerio learned by itself and you have not reviewed (packages you typed never ask); weight is per unit. The daily schedule offers four plans in plain words: Schedule + labels, Schedule only, and the same two page by page.

The card never invents a weight or a dimension. Easy Ship reweighs at pickup and bills the difference. An order whose SKU has no saved package and no value from Amazon waits for you and is named on the card; nothing is scheduled on a guess.

Seller Flex

Works on Pick and the Seller Flex dashboard; the run walks to the pick list and the packing page by itself.

Run all: Pick → Pack → Print

1. On Pick › Create, picks the day's card — Today, Tomorrow or All, your choice on the card — selects all and presses Activate N selected. All takes every day that has orders, one after the other, refreshing between days; then every active pick list is packed and printed in turn, and the card ends with the totals.
2. Opens Active pick lists and the newest pick list. Prints the pick list if Print pick list is on (a copy is saved to Downloads and the sheet opens in a background tab — see The pick list), then presses Start packing.
3. On the packing page, sets the box you chose before for each SKU when Fill boxes automatically is on. Then waits for you on every order whose box it did not set — Seller Flex's own box is often the wrong size — with the SKUs named on the card. Choose the boxes and press Continue → pack & print. Once every SKU on the page has a learned box, the run does not stop here at all.
4. Action Center › Print › Invoice and Ship Label, ticks Are you sure you want to proceed?, presses Continue. The labels go straight to your printer through QZ Tray, exactly as Seller Flex sends them — Sellerio does not touch a Seller Flex label, crop it, or print it a second time. The A4 invoice Seller Flex sends alongside each label is held back unless Print the invoice too is on.
5. Once the last label has printed, refreshes the page once so it shows the packed orders.

Activate pick lists only stops after step 1 and refreshes the page once, so it shows the activated list. If Create has nothing for the day (No new orders available), a full run looks at Active pick lists and packs the pick list waiting there; with nothing there either it says so.

Boxes: Sellerio learns what you choose

Seller Flex and Easy Ship share what they know. Every box Seller Flex offers is remembered with its size the first time its list is open. A SKU with an Easy Ship package but no Seller Flex box gets the smallest box its package fits in; a SKU with a Seller Flex box but no Easy Ship package lends that box's size to the Pickup Builder, where only the weight is left for you to type. Nothing is guessed: no size, no box.

Sellerio learns by itself, whether Fill boxes automatically is on or off: every box you set for a SKU — while a run waits, or by hand on the packing page — is learned from that one choice. Only your own hand counts: the box Seller Flex pre-fills on each row by itself (usually the wrong size) is never learned, however often it appears. The switch decides only whether what was learned is filled: on, the learned box is set on every later run through the row's own dropdown or the Select Box dialog and the run only waits for SKUs it has not seen yet; off, nothing is set and the run waits for you on every row. A box Sellerio does not know is never guessed, and the waiting card says for each SKU what it knows and, if it could not set it, why — Try again retries.

The pick list

Whichever way you print a pick list (Print pick list on the pick list, Print one selected pick list, or the ⋯ menu), one sheet comes out: Amazon's own header with the Pick Task ID and its barcode, and under it your SKUs set large with the location and quantity, marked Pick list by Sellerio. A copy is saved to your Downloads folder, and the same sheet opens in a Sellerio tab in the background — the run stays in front — with Print and Save PDF for whenever you want it on paper. Untick Large SKU pick list behind the gear to print Amazon's own sheet unchanged. Never both. The orange Download pick list button beside Seller Flex's own saves that sheet as a PDF for every order on the page, with nothing printed.

Settings

• Today / Tomorrow / All — which day's orders a run takes; the chosen one is lit in blue (orange on Amazon Easy Ship).
• Print pick list — print the pick list before packing. On by default.
• Large SKU pick list — untick to print Amazon's own sheet. On by default.
• Fill boxes automatically — set the boxes Sellerio learned for your SKUs. On by default.
• Print the invoice too — let the invoice Seller Flex prints with each label through. Off by default: only the label prints. The same switch is on the Seller Flex label chip.

Label auto-crop settings

On every marketplace a small Sellerio chip sits next to the marketplace's own label button. Click it to open the crop settings for that marketplace. The main switch, Auto-crop labels on download, is on by default; with it off the file saves exactly as the marketplace sent it.

Print automatically — and without the dialog

Under the main switch, on by default. Every label file Sellerio finishes — Amazon Easy Ship, Flipkart, Meesho — and the Seller Flex pick list print by themselves. Where they go is written under the switch, and depends on a one-time setup:

• Through QZ Tray, straight to the printer (3.7.8) — no print preview, nothing to press. QZ Tray is the free program Seller Flex already prints through. Open Set up printing from the link under the switch (on any chip, the toolbar popup or the side panel) and follow its four steps: 1. install QZ Tray from qz.io/download (it brings its own Java; if its installer asks for Java, get it from java.com and run the installer again — after that QZ Tray's icon sits beside the clock and starts with Windows); 2. press Save the certificate file (it saves override.crt to Downloads), then hand it to QZ Tray: right-click the QZ Tray icon beside the clock → Advanced → Site Manager… → the green + → Browse… → pick override.crt → Open; QZ Tray says the certificate is "unrecognized and not yet trusted" and offers to copy it into its own folder — answer Yes (Windows asks for permission once). No restart; from then on QZ Tray trusts Sellerio and never asks on that computer. Doing it by hand is the same thing: the file into QZ Tray's program folder (the one with qz-tray.jar, C:\Program Files\QZ Tray on Windows), then Exit and start QZ Tray again. To check, press Find printers: if QZ Tray still shows its Allow box (with Remember this decision greying Allow out), the import did not go through — the page says so; 3. press Find printers and choose one for label files (a 4×6 thermal printer, or an A4 printer for sheets) and one for the Seller Flex pick list (A4), each with a Test print; 4. done — the printers are saved on that computer. Skipped step 2? Printing still works, QZ Tray just shows its Allow box before each print.
• Chrome's print preview — with no QZ Tray, or no printer chosen, the file opens in a tab behind the page and Chrome's print preview appears with the printer you used last; one Enter sends it. The tab stays open, so if the printer did not take it you can press Print again.

Either way a copy is always in Downloads first, and Seller Flex labels keep printing the way Amazon prints them. No new Chrome permission is needed for any of this.

Printer & layout (all marketplaces except Seller Flex)

On every chip the switches come first — Print a number on every label last — and the choices after, under Printer & layout: the number's corner and form first, paper last. On Amazon Easy Ship, Print on label and SKU size sit right under the main switch.

Updating to 3.7.6 sets every switch above, and every Orders card switch and daily time, to these defaults once — for existing installs too. Your store links, your own label text and what Sellerio has learned are untouched. Change anything back by hand; it stays changed.

Files never leave your computer. The crop runs inside Chrome on the file the marketplace sent, and the result is saved as Sellerio_<Marketplace>_<original name>.pdf. Label settings follow your Sellerio account to every computer you sign in on.

Runs by itself

Auto-accept and Auto-schedule

With the switch on, the card checks the page every minute or so and starts the run when something is waiting. It needs the tab open on one of the pages listed below.

The daily schedule

Every card comes with one daily time already set, which you can change, remove or add to:

Add a time in IST and choose what to run. At that time the Toolkit looks for an open tab of that marketplace, brings it to the front and starts the run. If no tab is open, it opens the orders page itself in a new tab. Chrome must be running; if it was closed at that time, the run is skipped and a notification tells you so.

Auto-refresh — on your day’s rhythm, not a clock

Marketplace pages do not show a new order until they are loaded again, so the card loads its own page from time to time and Auto-accept or Auto-schedule takes what came in. From version 3.8.3 how often depends on the hour (IST):

The exact wait is drawn afresh every time — never 30 minutes on the dot — so the tab has no rhythm a marketplace could mistake for a script. Overnight it simply sits: nobody is dispatching at 3 AM, and a reload then buys nothing. Nothing is missed either — your own click runs at any hour, a daily time still fires, and the morning picks up whatever arrived while you slept.

It also waits for a quiet moment: never during a run, never within a minute of you typing, clicking or scrolling on that page, never with a text box focused or a dialog open.

Which page to leave open

Chrome's Memory Saver can put an idle tab to sleep. When you click the tab it loads again and the card carries on, but nothing ran while it slept. To keep a tab awake, open chrome://settings/performance, find Always keep these sites active, and add the marketplace's address.

Safe on your account

The Orders cards press the marketplace's own buttons on the page in front of you, in your own signed-in tab. There is no private connection to any marketplace, nothing is sent on your behalf, and nothing about your orders leaves your computer. Since version 3.8.0 the cards also work the way a person works, so a busy day never looks like a script to a marketplace:

• No two runs alike. Every wait a run makes varies, so a card never works to a clock.
• A break between batches. A long run rests for a few seconds after every ten to fifteen orders. You will see "a short break…" on the card.
• Buttons pressed the way a hand presses them. The pointer arrives on the button and presses inside it, rather than a bare click sent from nowhere.
• It stops at a security check. If a marketplace asks to confirm you are a person, says you have gone too fast, refuses the page or signs you out, the run ends there and the card says so. Sellerio never answers a security check for you, never reloads around it, and never tries again by itself.
• And that marketplace is paused for two hours. Not just the run: from version 3.8.1 nothing happens there by itself until the pause lifts — no 15-minute refresh, no Auto-accept or Auto-schedule, and no daily time (a notification tells you it did not run). The pause is for that one marketplace; the others carry on as normal.
• Three runs that get nowhere and it rests for an hour. Rather than trying a page it cannot work every fifteen minutes, the card stops and says why. A run that works clears the count.

You are never paused. Press any button on the card — Run all, Accept, Print — and it runs straight away, and that clears the pause, because you have just looked at the page yourself. If the marketplace is still asking, the run stops again at once and the pause comes back.

Nothing here pretends to be a person. A click made by an extension always tells the page it came from an extension, in every browser, and Sellerio does not hide that — it simply stops doing the things an honest helper had no reason to do.

Notifications

Chrome can show a notification when a run finishes or stops: "Run all: printed 12 labels", "Auto-accept: accepted 3 orders", or the reason it stopped. Click it to jump to that tab.

Chrome asks for this permission once. Turn it on from the Sellerio toolbar icon (Turn on Chrome notifications) or from the What's new page. The Notifications switch on each card turns it off again for that marketplace. Nothing about your orders, labels or customers is in a notification — only what the card did.

Habits

The card counts what you do by hand and, after it has seen the same thing a few times, offers to do it for you. The offer — Sellerio noticed — shows on the card itself, with the gear closed, and every offer waiting is listed at once: one Yes each, or Save all in one click; Not now and it never asks about that one again.

• Run Accept around the same time on four different days → it offers that as a daily time.
• Type the same weight and box for a SKU twice on Easy Ship → it offers to save that as the SKU's package. (While a run waits for a missing package, one entry with Remember ticked saves it at once.)
• Change the box for a SKU twice while packing on Seller Flex → it offers to set that box every time. (While a run waits for your boxes, one choice with Remember ticked learns it at once.)

Everything you said yes to is listed under What Sellerio learned in the Toolkit side panel (the Sellerio toolbar icon › Upload & Crop), each line with Forget, and Forget all. Easy Ship packages are edited in the Pickup Builder. Habits are counted on your Sellerio account, so they follow you to every computer you sign in on.

Settings across devices

The daily schedule is deliberately per computer: if it followed your account, two computers left open would both run it at the same time and print the labels twice.

When something looks wrong

Autofill & Insights

Sellerio Autofill (not on the Chrome Web Store at the moment — these notes are for sellers who already have it installed) sits beside every Amazon, Flipkart and Meesho listing form in Chrome's side panel: templates, defaults (GST, HSN, country of origin, manufacturer, packer, importer) filled into every listing that leaves them blank, bulk uploads from Excel, and image tools. A template saved on one marketplace can fill another's form with Fill here: title, description, brand, MRP, HSN, GST, country of origin, colour, size, material, manufacturer, keywords and bullet points go into the blanks; weights, dimensions, the selling price and stock never cross, because each marketplace has its own.

Sellerio Insights shows margin, fees and ranking signals on the product pages you browse.
