4.1 Register, Tally or app

3 min read

Draft: the wording may change.

The idea

A register, a desktop accounting package (what most people call "Tally") and a phone-and-web app all keep the same books by the same rules. What changes is who does the copying, adding and linking. Manual work goes wrong in exactly those three places.

Three ways to keep the same books

	Register	Desktop accounting ("Tally")	App (phone and web)
Who writes the entry	A clerk, by hand	A clerk, from the paper bill	Whoever makes the document — salesman, biller, cashier
Where it lives	One book, one shelf	One computer in the office	Online, seen from office and field
Reports	Added up by hand	Calculated, in the office	Calculated, anywhere
Field work	Paper order book	Paper, typed in later	Order and receipt taken on the phone
Typical weak point	Totals and copying	Late entry, one person bottleneck	Bad masters, too many people allowed to edit

None of these is "wrong". Many stockists ran for years on a register, and a well-kept desktop package is still the backbone of many offices. The question is where your time and your errors go.

At the counter

Follow one sale through a register office.

Salesman Kumar writes Ravi Stores' order in his order book: ₹1,180 with tax.
Back at the office, the biller copies it onto bill #245.
The accountant copies bill #245 into the sales day book.
Later, the same ₹1,180 is copied into Ravi Stores' ledger page.
Ravi pays ₹600. The cashier writes it in the cash book; someone copies it to Ravi's page.

The same rupees are written five times by four people. Each copy is a chance to slip: ₹1,180 becomes ₹1,810, a bill is missed in the day book, the receipt goes to the wrong Ravi. Each slip is small. Across 200 bills a day, they add up to a month-end where the cash, the stock and the outstanding do not agree.

In desktop accounting, steps 3 and 4 disappear: save bill #245 and the day book and the ledger are calculated from it. That is the rule from chapter 1.5, the bill is the entry, done by a machine. In an app, step 2 also disappears: Kumar's order on the phone becomes the bill, and his receipt on the phone reaches Ravi's ledger the same minute.

Where manual work goes wrong

Copying. Every time a figure is written again, it can change.
Adding. Hand totals drift. One wrong carry-forward spoils every page after it.
Linking. A receipt not tied to a bill leaves the ageing wrong (chapter 1.12).
Lateness. Entries made a week later are made from memory.

Software removes the first three. Only discipline removes the fourth.

Common mistake

Thinking software makes the books right. Software only does the copying and adding. If the clerk picks the wrong customer, enters the wrong GST rate or skips a credit note, the software repeats that error perfectly on every report. A wrong entry in a register is wrong once; a wrong master in software is wrong on every bill.

Where you'll use this

This chapter automates the bill is the entry (chapter 1.5) and same lines, sorted twice (chapter 1.7): store the postings once, calculate every book from them. The rest of Part 4 shows each process from Parts 2 and 3 done this way.

Answers

Four times for the sale (order book, bill, day book, ledger), and the receipt twice more.
The day book and ledger entries — they are calculated from the saved bill, because the bill is the entry.
A wrong choice by the person: wrong customer, wrong rate, a missed document, or a late entry.
