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

Crop and print shipping labels, then accept orders and schedule pickups — by hand, or at a daily time you set.

Sellerio Seller Toolkit works inside Amazon Seller Central, Amazon Seller Flex, the Flipkart Seller Hub and the Meesho Supplier Panel. It crops your shipping labels the moment you download them, prints them for you, and accepts, prints and marks your orders on a daily schedule — with a Chrome notification when it is done. A Sellerio account is required to sign in — Sellerio's own, not your marketplace login. Nothing to pay for, no API key to paste. ━━━━━━━━━━━━━━━━━ WHAT IT DOES, PER MARKETPLACE ━━━━━━━━━━━━━━━━━ AMAZON EASY SHIP One card on your orders page schedules the day's pickups and downloads the labels in one run: the toolkit requests your unshipped orders report, builds the pickup file from the weight and box saved for each SKU, uploads it, and downloads the labels — every one cropped to 4×6 with the SKU and quantity printed on it. Prefer Amazon's own page-by-page scheduling? That works too, with the weight and box filled in for you. Every order you schedule teaches the toolkit that SKU's package, averaged over time, so the next run needs less of your typing. AMAZON SELLER FLEX Pick, pack and print for today's or tomorrow's shipments from one card. The pick list Amazon prints at 8pt is re-set in large type — location, FNSKU, SKU, quantity — with Amazon's own header and barcode kept on top. The box you set for a SKU is remembered and filled in next time. Labels print through QZ Tray exactly as Amazon prints them; the invoice is held back unless you want it. FLIPKART SELLER HUB Orders waiting in To Accept are accepted, labels printed and orders marked Ready to Dispatch from one card. Labels are cropped from Flipkart's own file, for a single order or a bulk selection, on both label formats Flipkart generates. MEESHO SUPPLIER PANEL Pending orders are accepted and the Ready to Ship labels downloaded and cropped, grouped by courier partner so each rider's parcels come off the printer together. An optional "Follow us on Meesho" QR sticker goes on every label, matched to the right store even when one batch mixes several. ━━━━━━━━━ PRINTS BY ITSELF ━━━━━━━━━ Every label file the toolkit finishes — and the Seller Flex pick list — goes to the printer without you pressing anything. Install QZ Tray, the free tray program Seller Flex already prints through, choose a printer for label files and one for pick lists on the toolkit's Set up printing page, and there is no print preview and nothing to click: a 4×6 thermal printer prints one label per page, an A4 laser printer prints the sheets. Without QZ Tray, Chrome's print preview opens behind the page with your last printer chosen, one Enter away. A copy of every file is always in Downloads first. ━━━━━━━━━━━━ RUNS ON A SCHEDULE ━━━━━━━━━━━━ Each card has a daily time in IST — set from the first day, changed in a click. At that time the toolkit runs the plan you chose on the open marketplace tab, refreshes the page every 15 minutes so new orders are seen, and tells you in a Chrome notification what it accepted, printed and scheduled, and what needs you. Auto-accept while the tab is open is a switch away. A run that needs a decision — a SKU with no box size, an order with several items — pauses on the card and asks, and never guesses a weight or a box. ━━━━━━━ ON THE LABEL ━━━━━━━ • Sorted SKU-wise, so a picker pulls one SKU's whole run in one trip. Orders with more than one SKU go last, where they get the most care. • Multi-quantity orders first, each carrying a small solid QTY block, so a three-item order never looks like a one-item order. • A sequence number in a corner of every label. A roll runs out at label 47 of 70: read the last clean number, change the roll, reprint from the next. The corner is measured per marketplace so it never lands on a barcode. • Thermal roll or A4 sheet: one label per page for a 4×6 roll, or two or four labels tiled onto A4 with cut guides for sticker sheets. • On Amazon: the SKU and quantity, optionally the title, in three sizes; your own line of text on every label; the date and time the batch was processed; a pick list with one row per SKU. • Keep the invoice as its own page, or crop it away. ━━━━━━━━━━━━ LEARNS YOUR PACKING ━━━━━━━━━━━━ The toolkit notices what you do by hand — the box you choose for a SKU on Seller Flex, the weight and size you type for it on Easy Ship, the time of day you run — and offers to do it for you, on the card, with a Yes and a Not now. It never acts on a habit without your yes. What Seller Flex learns about a SKU's box and what Easy Ship learns about its package are shared, so a SKU set up on one is ready on the other. It is kept on your computer, and carried to your other computers through your Sellerio account when you are signed in. ━━━━━━━━━━━━━━━━━━━━━━━━━ 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. ━━━━━━━━ WHO IT IS FOR ━━━━━━━━ Sellers and suppliers in India who print shipping labels every day and would rather not accept, print and mark orders by hand. It suits one person with ten orders a day as well as a packing bench with five hundred. Nothing about your workflow changes: you keep using each marketplace's own buttons, and the toolkit does the rest under the same click. ━━━━━━━━━━━━━ PRIVACY & PERMISSIONS ━━━━━━━━━━━━━ Everything runs inside your browser. Label files are cropped on your computer and are never uploaded anywhere. The extension stores no order, address or customer detail. There is no <all_urls> permission and no browsing-history access. The toolkit does report which feature you used and how many labels it cropped, so we know what is worth improving — never what was on them, and never a page address, an order number or a customer. It 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 means reaching that host. • Amazon's own file storage — Seller Central serves label PDFs and the unshipped orders report from Amazon's storage servers rather than from the page itself, so opening the file you just asked for means reaching them. The toolkit reads only that file, from the link Amazon gave for it. Chrome lists the exact addresses when you install. • api.sellerio.in — your Sellerio account. Signing in is what unlocks the toolkit, keeps your settings the same on every computer you sign in on, and stores the package sizes you save in the Pickup Builder. Printing through QZ Tray happens on your own computer over a local connection; nothing about it leaves your machine. Chrome notifications are optional and asked for once. ━━━━━━━━━━━━━ ONE HONEST LIMITATION ━━━━━━━━━━━━━ On a small number of Amazon 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 Chrome platform limitation, not something specific to this extension. If auto-crop does not apply there, download the file as usual and drop it into the Upload & Crop side panel, or crop it free at https://sellerio.in/ecommerce-label-crop. ━━━━━━━━━━━━ THE REST OF SELLERIO ━━━━━━━━━━━━ Two companions, each a separate free install: Sellerio Insights shows real net margin after fees, listing health, stock cover and category rank on any Amazon product page from your own Sellerio data; Sellerio Autofill fills Meesho and Flipkart listing forms from a saved template.
