Cost calculator

What is it costing you now?

Orders typed twice, a month-end that takes a week, stock written off because the count was wrong, input tax credit (ITC, the GST you can set off) lost because a supplier never filed. Put in your own figures. The working shows line by line below.

It measures what today's way of working costs. It is not a return-on-investment calculator.

Last reviewed 13 October 2026. Section 17(5) of the CGST Act, which governs blocked input tax credit, is the only statute cited.

Your numbers

Eight inputs, each with the reason for its default.

Each field starts at a default for a trading business of forty people. The reason sits under each field. Two of the eight start at zero, because we cannot guess them for you.

The sums run in your browser. Your figures never leave it. Nothing you type is sent to us, stored, or saved on this device. Reload the page and it is gone. Two exceptions, both your choice. Pressing “Request an invitation with these figures” at the foot of the page keeps the working in this browser tab until you close it, so the application form can show it to you. It is sent only if you then send the application. Asking for the summary by email, at the bottom, sends the figures, and only if you type an address and press the button. One thing is always sent: a record that somebody used this calculator (an event name and a path), like a page view. It carries none of your numbers.

People whose week this touchespeopleAnyone who re-keys, reconciles or chases. Not your whole headcount.Hours each of them loses a weekhoursRe-typing between systems, hunting for a number, rebuilding a report. Count each hour once (see the note below).Working weeks in your yearweeks46 allows six weeks for holidays, festivals and slow time. Lower it if you shut for Diwali, raise it if you do not.Loaded cost of an hour₹/hourSalary plus everything on top of it. ₹250 an hour is about ₹4.6 lakh a year at 1,840 working hours: an executive or a junior accounts person, not a director. Use a director’s cost and the total tells you about who you counted, not your process.Days month-end takesdaysFrom the last day of the month to a number you would show a bank.People tied up in month-endpeopleOnly those whose day it takes. Usually two; one in a smaller business.Stock written off a year to bad counts₹Starts at zero on purpose. We cannot guess this, and a default would be us adding money to your total. Count only losses caused by a wrong figure. Not theft, not damage, not old stock you would have written off anyway.Input tax credit lost or reversed a year₹Also starts at zero, for the same reason. Credit reversed, or never claimed because nobody read GSTR-2B (the monthly list of purchase invoices your suppliers filed) before the deadline. Leave out credit blocked under Section 17(5). It was never yours to claim and no system recovers it.

Roughly what it costs you a year

How the yearly figure is worked out, line by line
Cost line	Working	Per year

This is your arithmetic, not a forecast. We do not know your business. It shows what the current way of working costs. If the figure is small, that is a real answer, and you may not need new software at all.

Count each hour once. The matching-up your accounts person does in the first week of the month goes in the weekly hours or the month-end days, never both. Counting it twice makes the number one you cannot defend, and whoever you show it to will spot it.

What the total leaves out, in both directions

Four costs left out. Each one weakens the case for buying anything.

A calculator that only leaves out what would shrink its own number is a sales tool.

The cost of any new system. Nothing above subtracts software, setup or moving your data. The total is one side of a sum. Ordence's commercial terms are shared privately with invited businesses, so you finish the sum with real figures, not our guesses.
Your own time during the project. Someone in your business has to answer questions, check the moved data against a figure they trust, and get people off the old spreadsheet. Most vendors leave this out, and it often decides whether a rollout works. Nobody can size it for you. It is not zero.
The months before anything changes. The number above is yearly. None of it arrives on day one. A module goes live, people keep the old way beside it for a few weeks, and the saving comes slowly and in part. Treat the first year as a fraction of the total.
Any share we would recover. We do not apply a percentage to your figure. There is no payback period here, because one worked out from an invented saving would be a trick.

Why these four costs and not others

They show up in almost every trading business, and you can estimate them from your own records.

A calculator that adds up anything gives a number you cannot defend. These four appear in almost every trading business this size. One system holding the order, the stock and the invoice changes each of them.

Re-keying. The same order, lot number or invoice typed into a second system by someone paid to do something else. The dullest line here, and usually the largest.
Month-end. Not the accounting, but the matching-up before it can start. One ledger does not shorten your books. It ends the argument about which system was right.
Stock written off. Only what went wrong because the number was wrong: a lot the register showed in rack 4 that was sold last month. If you hold no stock, set it to zero and the sum still works.
Input tax credit. ITC claimed then reversed, or never claimed because GSTR-2B was opened too late. Real money, invisible until an audit.
What is NOT here: sales you might win, deals you might close faster, customers you might keep. Those are real, but we cannot estimate them for you, and adding them would make the total less believable.

And this is not a return on investment. That needs two numbers: what you spend and what you get back. The calculator has neither. It measures the waste in how you work today (hours, stock, lost credit) and stops there. It does not claim Ordence would recover any share, because nobody can know that before seeing your data.

Make us prove the saving on your own figures before you commit to anything.
