About these tools
Tools for selling online in India, on Amazon.in, Flipkart, Meesho or your own shop: check and resize product photos, check listings, package labels and product pages, build size charts and product import files, work out fees, discounts, ad costs, GST, shipping weight and the cost of cash on delivery and returns, write your return, refund and shipping policies, check your pages for misleading design, print packing slips, and plan order messages, stock, reviews and customer value. They work in your browser on what you type, paste or open; only the Product Page Checker and the Store Product Audit fetch pages, the public pages of the shop you name. None of them sign in to your seller accounts.
Built on official rules
Rules come from the marketplaces' own seller help pages, the Legal Metrology (Packaged Commodities) Rules, the Consumer Protection (E-Commerce) Rules, the CCPA's guidelines on dark patterns, CBIC's GST rules and Google's Merchant Center and Search Central documentation. Where a figure, score or suggestion is our own, the tool says "our checklist", "our measure" or "our suggestion".
What these tools do not do
They do not sign in to Seller Central, Seller Hub, Meesho or your shop, and they do not change your listings. Fees and rates change, so the calculators use the rates you enter from your own rate card. Nothing here is legal or tax advice; check with your CA or lawyer before you rely on it.
Frequently asked questions
Do these tools sign in to Amazon or Flipkart?
No. You type or paste your details, or open your own files, and the tool works on them in your browser. Nothing is uploaded and no seller account is connected.
Are the marketplace fees up to date?
Marketplaces change their fees often and by category, so the fee calculator does not guess them. Enter the rates from your own rate card in Seller Central, Seller Hub or the Meesho supplier panel, and the tool works out the rest.
Is this legal or tax advice?
No. The tools follow the published rules and say where each one comes from, but your CA or lawyer should confirm anything you rely on for GST, labels or policies.
Do these tools use AI?
No. They check, count and calculate with clear rules on what you give them. Templates are fixed text you fill in.
Are these tools free?
Yes. Every tool on this page is free, with no sign-up and no limit on how often you use it. They are made by DigitalSnot, a digital marketing agency in India, alongside our free SEO, Google Ads, YouTube, content writing and social media tools.
