About jit.delivery

Who operates this site

jit.delivery is built and operated by S.B. Ajay, an individual supply-chain practitioner based in Chennai, Tamil Nadu. This site is my freight-economics suite, the delivery-side companion to outofstock.in, 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 freight and delivery-economics calculators: freight cost per unit moved, a current-versus-optimised lane comparison, and a controllable-versus-structural cost stack. Each one takes the figures you already know (lane distances, freight rates, truck fill, volumes) and works through a standard method to a plain-English result in rupees.

They pick up exactly where inventory planning stops. Once you know how much each location should order and when, the next question is what moving it that way actually costs: per unit, per lane, per return leg. That question usually gets answered inside a transport-management system someone else configured, a broker's quote you can't decompose, or a spreadsheet with assumptions nobody remembers. If you run distribution for a growing business or an MSME, you shouldn't have to reverse-engineer any of those to answer “what does one unit cost to move on this lane?”

The methods themselves are standard industry practice: the same body of distribution and freight-economics 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. Freight is even less standardised than inventory. Rates differ by lane, vehicle, contract, and season, and there is no universal Indian benchmark for truck fill, empty running, or fuel pass-through that holds across operations. So wherever a figure like that matters, the tools let you set your own and read the result against it, rather than asserting a number as fact.

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: this is your starting number, not your final answer. Validate it against your own lanes, rates, and costs before you act on it. Where the stakes are high, validate it against a qualified professional's advice too. 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 calculation is doing and decide whether it fits your situation, instead of trusting a result you can't inspect.
