ERP worksheet

# 

Tally, spreadsheets and a WhatsApp group cost staff hours every week. Put in your own numbers and see the yearly cost. Every assumption is shown. No Mach ERP price.

What the worksheet pricesThe hours spent typing the same order again: into a sheet, into Tally, into the GST portal.

Your plant today

## 

Start with honest guesses. The defaults are deliberately low.

People who type the same work twice

Sales, stores, accounts, the floor. Anyone who copies an order, a GRN or an invoice from one place into another.

Hours a week each, re-typing or reconciling

Per person. Copying, checking one sheet against another, chasing the latest version.

Hours a week on GST paperwork

For the whole team. E-invoices, e-way bills, return prep, matching purchase data.

Cost of one working hour

Salary plus PF and overheads, divided by hours worked. Pick the closest.

Cost of one working hour₹ 200₹ 300₹ 400₹ 500

GST corrections in a year

Credit notes, amended returns, notices answered. Counted at ₹ 5,000 each.

Where one order lives today

Tick every place the same order, stock or invoice gets typed.

A worksheet, not a quote. No Mach ERP price is in it.

Assumptions

## 

If an assumption looks wrong for your plant, change the input. If it cannot be changed, it is listed here.

* ### Time

  * 48 working weeks a year. Leave, holidays and shutdowns come out. Fewer weeks means a smaller number, not a bigger one.
  * One full-time person is 2,304 hours. A 48-hour week for 48 weeks. Used only to turn hours into people.
* ### Money

  * Your hourly cost, not ours. Pick the closest: salary plus PF and overheads, divided by hours worked. The default is ₹ 300 an hour.
  * One GST correction costs ₹ 5,000\. CA time, staff hours, and interest or a late fee. A low figure. Notices that turn into demands cost far more and are not counted.
* ### Your scenario

  * The share that goes away is your call. Pick 25, 50 or 75 per cent. It is a scenario, not a Mach ERP performance figure. We do not publish one.
  * No Mach ERP price. The worksheet costs your current setup. It is not a quote, and it does not net off a licence fee.
* ### Left out

  * What is not counted. Stock bought twice, a price that changed in a chat, a payment missed, a late dispatch. They are real, but hard to price honestly, so they are left out.
  * Nothing leaves this page. The worksheet runs in your browser. It does not send your numbers anywhere unless you choose to WhatsApp them.

Next step

Bring a Tally export or an item list. We will show you what it looks like in Mach ERP.
