About outofstock.in

Who operates this site

outofstock.in is built and operated by S.B. Ajay, an individual supply-chain practitioner based in Chennai, Tamil Nadu. This site is my inventory-planning suite.

This suite is actively maintained, not published once and left alone. If you spot something off or want to suggest a tool, reach me through the Contact page.

What the tools are, and why they exist

The suite is a connected set of inventory-planning calculators: safety stock, reorder point, economic order quantity, a stockout-cost estimator, inventory turnover and days of supply, and ABC classification. Each one takes the figures you already know (your demand, lead times, ordering and holding costs) and works through a standard formula to a plain-English result.

I built them because the underlying methods are well established, but the tools that apply them are usually locked inside paid ERP modules, spreadsheets that someone else set up, or foreign calculators that quote figures and currencies that don't match how an Indian operation actually runs. If you handle stock for a growing business or an MSME, you shouldn't have to reverse-engineer a spreadsheet to answer "how much buffer do I need?" or "when should I reorder?"

The formulas themselves are standard industry methods: the same body of inventory-planning knowledge taught in professional operations and supply-chain certification. I don't claim them as my own; what I offer is a clear, honest, India-facing way to use them.

How I think about the numbers

My editorial stance is simple: a calculator gives you a starting number, not a final answer. Where a tool shows a status read or a benchmark band, treat those bands as illustrative unless the page says otherwise. There is rarely a single "correct" target that holds across industries, so wherever it matters I let you set your own target and read the result against it, rather than asserting a universal figure.

That means every result is only as good as the inputs and the judgement you bring to it. I say so plainly on each tool: validate the output against your own lead times, costs, and demand, and where the stakes are high against a qualified professional's advice, before you act on it. I would rather give you a number you can defend than one that looks authoritative and isn't.

I also keep the workings visible. The explanations sit on the page in plain language, so you can see what a formula is doing and decide whether it fits your situation, instead of trusting a result you can't inspect.
