Built by someone who runs warehouses
WarehouseOps exists because of a small, persistent irritation: every few months, somewhere in a warehouse, someone rebuilds the same spreadsheet. Safety stock. Pallets per truck. Whether the racking will hold what the plan says it will hold. The maths is not hard, but it is fiddly, easy to get subtly wrong, and nobody has time to do it carefully at four in the afternoon with a truck waiting.
So here are the calculations, done properly, with the formula shown so you can check them.
Who is behind it
Twenty-five years in warehousing and logistics in India — spare parts and distribution, across multiple sites in the east and north-east, at scales from a single godown to over 150,000 sq ft and a couple of hundred people. SAP from the operational side rather than the consulting side. A postgraduate diploma in logistics and supply chain management, finished recently, which mostly confirmed what the floor had already taught but did put names to some of it.
The site is deliberately published under a brand rather than a personal byline. Nothing here draws on any employer's data, documents or systems. Every figure in every example is illustrative, every method is general industry practice, and anything that looked like it belonged to an employer is not on this site.
Part of Amit Mehta Group
WarehouseOps is one of the properties operated by Amit Mehta Group, alongside Chai Ki Gumti. Each runs independently with its own focus; this one covers warehousing, inventory and logistics.
Practically, that means the calculators and guides here are maintained as a long-term property rather than as a side project that stops being updated. Formulas get corrected when they are wrong, defaults get revised as conditions change, and tools get added as gaps appear.
What the defaults are based on
The pre-filled numbers on each calculator are realistic rather than round. The Indian vehicle presets, the 18–25% holding-cost range, the 75–82% productive-time assumption, the aisle allowances — these come from the conditions Indian warehouse operations actually run in, not from an American textbook. Where a figure varies enough that a default would mislead, the page says so and tells you to measure your own.
The “common mistakes” sections are the part worth reading. Most are mistakes made at some point along the way, which is why they are specific.
On your data
Every calculator is plain JavaScript running inside your browser. There is no server-side processing, no analytics on what you type, no upload of anything. You can disconnect from the internet after the page loads and the tools keep working. Paste real stock figures if you want to — they physically cannot reach anyone.
The one exception is the free KPI starter pack, which is emailed rather than downloaded — so that one address is stored, and nothing else. It is not sold, not shared, and not used for a newsletter; you get the workbook and that is the end of it. Write to support@warehouseops.in at any time to have the address deleted.
What this is not
It is not a consultancy, and no advisory or client work is offered through it. It is not software that connects to your WMS. It is not a substitute for a rack design from a qualified engineer, or for a customs broker's advice on your HSN codes. The calculators are planning tools — good enough to make a decision with, not a certification.
Corrections and contact
If a formula here is wrong, or a default is unrealistic for your part of the industry, that is worth knowing and worth fixing. The tools improve mainly by being argued with.
Write to support@warehouseops.in — for corrections, for a calculator you wish existed, or about the templates. It is a small operation, so every email is read by the person who built the tools.
