Sellerio — Seller Toolkit for Amazon, Seller Flex, Flipkart & Meesho

Auto-crop shipping labels on Amazon, Seller Flex, Flipkart & Meesho — click their download button, get a print-ready label.

Sellerio Toolkit auto-crops shipping labels the moment you click Amazon Seller Central, Amazon Seller Flex, Flipkart Seller Hub or Meesho Supplier Panel's own download button — no separate upload step, no visiting another site, no thermal-printer settings to fix. The file that lands in your Downloads folder is already a clean, print-ready 4x6 label. Built for Amazon, Flipkart and Meesho sellers in India who print shipping labels every day and are tired of trimming invoices by hand, fighting oversized PDFs, or re-entering the same SKU stamp on every label. Free to use. A free Sellerio account is required to sign in — Sellerio's own, not your marketplace login. Nothing to pay for, no API key to paste. ━━━━━━━━ HOW IT WORKS ━━━━━━━━ Click your marketplace's own download or print button exactly as you do now — Print Label, Reprint Label, Print Labels, or the bulk Ready to Ship / Schedule Pickup flow. The extension catches the file at that moment, processes it entirely on your own device, and saves the finished version under the same click. Nothing about your workflow changes. There is no new screen to learn and no step to remember. ━━━━━━━━━━━━━━━━━ NEW: A NUMBER ON EVERY LABEL ━━━━━━━━━━━━━━━━━ A thermal roll runs out at label 47 of 70. The printer stops mid-label, and nothing on the paper tells you which one it was. The usual recovery is spreading printed labels across a table and matching them against the PDF by AWB. Every cropped label now carries its own sequence number. Read the last number that came out clean, change the roll, reprint from the one after it. Done. • The count runs continuously across every file in a batch. Upload three files of 10, 15 and 20 and you get 1 to 45 — not three batches each starting at 1. • Invoices never take a number. With "keep invoice" on, 45 orders still read 1 to 45, not 1 to 90. • The number's corner is measured per marketplace, not guessed. Each marketplace's real label was rendered and checked for clear space: Amazon's top-right is empty, so the number goes there. Meesho prints a solid black banner across its top right, so Meesho's number goes bottom right instead. You can move it to any corner, and your choice is remembered. • Choose a plain number (7) or the number with the batch total (7/45), so you also know how many are left. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ NEW: PRINT ORDER, YOUR OWN TEXT, AND A DISPATCH TIME ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Three optional additions to any Amazon batch. All three are off unless you turn them on. SORT LABELS SKU-WISE Without it, labels come off the printer in the marketplace's order, which is effectively random by SKU — so a picker walks the shelves once per label. Grouped, they pull one SKU's whole run in a single trip. On a 70-label batch that is the difference between 70 shelf visits and one per distinct SKU. Orders containing more than one SKU are placed at the end rather than filed under whichever of their SKUs happened to sort first. They cannot honestly be grouped under any one of them, and they are the orders that need the most care while packing, so they are collected in one place instead of scattered through the batch. PRINT YOUR OWN TEXT ON EVERY LABEL A dispatch note, a thank-you, a return instruction — your line, on every label in the batch. It prints under the SKU in the same area of the label that was measured as safe to draw on, so it can never land on a barcode. A label that will not scan is a worse problem than a label without a thank-you note on it, and that trade decided where this prints. PRINT DATE AND TIME Stamps when the batch was processed — 17-08-2026 09:54:13 AM. One time for the whole batch, not one per label, so every label in a job agrees on when it was dispatched. ━━━━━━━━━━━━━━━━━ WHAT IT DOES, PER MARKETPLACE ━━━━━━━━━━━━━━━━━ AMAZON SELLER CENTRAL Crops the shipping label to a clean 4x6in and stamps the SKU and quantity — and optionally the product title — straight onto it, read automatically from the order's own invoice. The line reads 3L-MEAT-GRINDER-WH Qty:1: the SKU plain, because its shape already says what it is, and the count labelled, because that is the number a packer can misread. Three sizes, so it can be discreet enough to read like the label's own print or large enough to read across a bench. Works for single-order and bulk label printing (Schedule Pickup, Upload Order Related Files). Optionally saves a pick list alongside: one row per unique SKU with the total quantity across the whole batch, to carry into the warehouse and tick off while picking. FLIPKART SELLER HUB Auto-crops both "Print Labels" and "Re-Print Labels" downloads, for a single order or a bulk selection, on both label formats Flipkart generates. MEESHO SUPPLIER PANEL Crops the invoice off the shipping label — or keeps the full A4 page, your choice — for single and bulk downloads. Includes an optional "Follow us on Meesho" QR sticker, matched automatically to the right store even when one batch mixes several stores. AMAZON SELLER FLEX Seller Flex labels are recognised by reading each page rather than by cutting at a fixed position, and a page that is not recognised is downloaded untouched with an explanation rather than cropped on a guess. The pick list works here too where the file carries readable SKUs; where it does not, you are told so rather than handed a sheet with guessed quantities on it. Seller Flex is a newer, more varied surface than the other three: many warehouses print straight to a connected thermal printer through QZ Tray rather than downloading a file at all. Where a file does download, it is cropped like any other. Where it does not, use the Upload & Crop side panel below. We would rather tell you that plainly than have a label come out wrong on a pickup deadline. ━━━━━━━━━━━━━━━━━━━━━━━━━ UPLOAD & CROP — FOR A LABEL YOU ALREADY HAVE ━━━━━━━━━━━━━━━━━━━━━━━━━ Open the side panel and drop in any label PDF you already have — downloaded on another computer, from a different account, or printed earlier. Same crop engines, same numbering, same options, for Amazon, Flipkart and Meesho. Useful when someone else pulled the labels, or when a marketplace serves a file the browser will not let any extension intercept. Seller Flex is not a tab here, deliberately: it prints through QZ Tray straight to the printer and never produces a file to drop in, so a tab could only ever sit empty. Seller Flex is still cropped in the page itself, where a file does download. ━━━━━━━━━━━ WHY SELLERS USE IT ━━━━━━━━━━━ • No more manually cropping or trimming invoice text off a label before it goes to the thermal printer. • Every file is renamed Sellerio_<Marketplace>_<order name>.pdf, so you can tell at a glance which order it is instead of hunting through a folder of generic "label.pdf" downloads. • An in-page panel sits right next to the real download button on each marketplace — draggable, so it never covers anything — with the same options mirrored in the toolbar popup, and a light/dark/system theme that follows how you already browse. • Nothing is uploaded. Every crop happens in your browser. ━━━━━━━━━━━━━ PRIVACY & PERMISSIONS ━━━━━━━━━━━━━ Labels are processed locally in your browser. They are never uploaded to Sellerio or anywhere else, and nothing about them leaves your device. There is no <all_urls> permission, no browsing-history access and no analytics. The extension asks only for: • The four marketplace sites it works on — sellercentral.amazon.in, sellerflex.amazon.in, seller.flipkart.com, supplier.meesho.com • storage.googleapis.com — Flipkart and Meesho serve their label PDFs from signed Google Cloud Storage links, so reading the file you just asked for requires reaching that host • api.sellerio.in — your Sellerio account. Signing in is what unlocks label cropping, and this is the host that check goes to A free Sellerio account is required to use the extension. Signing in also syncs your settings across machines and connects the full Sellerio dashboard at https://sellerio.in. You stay signed in until you sign out yourself. ━━━━━━━━━━━━━ ONE HONEST LIMITATION ━━━━━━━━━━━━━ Amazon bulk label printing — Schedule Pickup and the Upload Order Related Files bulk status page — works whether you print a whole batch or a single listing from either page. On a small number of accounts, the single-order Print/Reprint button inside an individual order's own page serves the file in a way Chrome's security model blocks any extension from intercepting. That is a genuine Chrome platform limitation, not something specific to this extension, and no extension can work around it. If auto-crop does not apply there, download the file as usual and crop it free in seconds at https://sellerio.in/ecommerce-label-crop — or drop it into the Upload & Crop side panel. ━━━━━━━━━━━━━━━━━━ THE REST OF THE SELLERIO TOOLKIT ━━━━━━━━━━━━━━━━━━ Two companions, each a separate free install: • SELLERIO INSIGHTS — real net margin after fees, listing health, stock cover and category rank on any Amazon product page, from your own Sellerio data. It shows "not tracked" rather than inventing an estimated-revenue number the way most research extensions do. • SELLERIO AUTOFILL — fills Meesho and Flipkart listing forms from a saved template, so a catalogue upload stops being an afternoon of retyping the same attributes. And Sellerio itself (https://sellerio.in) is the platform behind them: multi-marketplace orders, inventory and warehouses, GST and TDS, purchase orders and landed cost, payment reconciliation, P&L and balance sheet, ads and ACOS, returns and claims — built for Indian marketplace sellers rather than translated from a US product. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Sellerio Toolkit — Amazon, Seller Flex, Flipkart and Meesho shipping label auto-crop, SKU stamping, numbering and reprint tool for Indian e-commerce sellers.
