The khata entry that went on the wrong page

Find it, do not erase it. Write a dated correction line on both pages: minus on the page that got it wrongly, plus on the page it belonged to, with a short reason on each. Then tell the customer before he finds it himself. An erased entry looks like something you were hiding.

Two names that sound the same, and one crowded evening

Six in the evening. Four people at the counter, a boy waiting for change, the phone going in your pocket. A man takes a bag of rice, a tin of oil and two packets of tea, says "put it in the book" over his shoulder and walks out. You open the book, turn to the page you always turn to, and write Rs 3,400.

The page said Naseer. The man was Nasir.

Nothing about that evening felt like a mistake. You wrote quickly because four people were waiting, and you turned to the page your hand knows. Weeks later both pages have been added up several times, other entries sit under the wrong one, and neither total is true any more.

This is not a rare accident in a shop that gives credit. Two customers share a name. Two brothers use the same page. A helper writes for you on a day you are out, and puts the line where he thinks it goes. The book stays neat, the arithmetic stays correct, and the record is still wrong, because arithmetic cannot see whose page it is adding.

The two ways you find out, and one of them is much worse

The good way is that you find it. Turning pages on a slow afternoon, you see a line that does not fit the customer, and something in you says: he does not buy oil in tins. You have time, a quiet shop, and the choice of how to tell people.

The bad way is that the customer finds it. He is reading his page for some other reason, he sees goods he never took, and the first thing he says is not about the entry. It is about you. Once the sentence "so how many others have you written on my page?" has been spoken across a counter, no amount of arithmetic puts it back.

That is why an unread page is expensive. A shop where customers see their balances regularly catches this in days. A shop where nobody looks catches it in a year, by which time the wrong page has been quoted, argued about and half paid.

Say Rs 3,400 of Nasir's goods gets written on Naseer's page

What Nasir really owes youRs 9,200

What his page shows after the entry goes elsewhereRs 5,800

What Naseer really owes youRs 1,150

What his page shows insteadRs 4,550

Money you will chase from a person who never took the goodsRs 3,400

Money the right person will stop expecting to payRs 3,400

One line in the wrong place moves this muchRs 6,800

Made-up names and figures, chosen to show the shape. The amount doubles because it is missing on one page and sitting wrongly on another.

Look at what the arithmetic does. One line worth Rs 3,400 is not a Rs 3,400 problem. It is missing from one page and sitting wrongly on another, so the shop's picture of who owes what is out by Rs 6,800. You will chase money from a man who took nothing, and the man who did take it will settle up believing he is clear. Both of those cost you, and the second one usually costs you permanently.

Do not rub it out

The first instinct is always the same: get rid of the wrong line. Rub it, scratch it, run the pen through it, or tear the page out and copy the good entries onto a fresh one.

Every one of those makes your book weaker. A page with a clean scratch on it is a page somebody altered, and a reader cannot tell whether it was altered honestly. A torn-out page is worse: you have removed the one thing proving what was written. If that customer later disputes something else, the state of your book is part of your answer, and a book full of erasures answers badly.

✓Correct it like this

• Leave the wrong line exactly where it is, readable
• Write a fresh dated line that cancels it, with the reason
• Write the matching line on the page it belonged to
• Say which entry you are correcting, by its date and amount
• Tell both customers yourself, the same day

✕Never like this

• Rubbing it out, scratching it, or covering it with ink
• Tearing the page out and copying the rest fresh
• Quietly changing the total and saying nothing
• Waiting for the customer to notice it himself
• Correcting one page and forgetting the other one

A correction that stays visible does the opposite. It says: I wrote this, I found it, I fixed it on this date, and here is why. Nobody reading that page thinks you are hiding anything, because you clearly are not. This is the same reason a written record beats memory when a customer says he already paid you. The value is not in the neatness. It is in the fact that nothing has been removed.

The correction that both sides can read

A correction is not one line. It is two, on two pages, made the same day, and each one names the other.

Correcting a wrong entry in about five minutes

1. 1Find the original line and read it out to yourselfNote its date, its amount and the words written beside it. That is what your correction has to name.
2. 2Cancel it on the page that should never have had itA new line with today's date, the same amount the other way, and four words of reason.
3. 3Add it to the page it always belonged toSame amount, the original date of the sale, and a note saying it was moved from elsewhere.
4. 4Read both new balances out loud before you close the bookIf the two pages do not move by the same amount in opposite directions, something is still wrong.
5. 5Call the person whose page was wrongly loadedHe is the one with a reason to be angry, so he hears it from you first.
6. 6Tell the person whose balance just went upGive him the date and the goods, not just a number. The date is what makes him remember it.
7. 7Write one line about how the mistake happenedTwo similar names, a rushed evening, a helper writing for you. Naming it is how you stop it repeating.

The wording does not need to be clever. On the page that wrongly received it: "Rs 3,400 written here in error, entry belongs to Nasir, corrected today." On Nasir's page: "Rs 3,400, rice, oil and tea, taken on the earlier date, moved here from another page today." The two dates matter. The original date is when the goods left the shop, and that is what makes the customer remember the sale. The correction date is when you fixed the book, and that is what makes the page honest.

Check the arithmetic by watching the pair. One balance goes down by Rs 3,400, the other goes up by Rs 3,400. If both moved the same way, or only one moved, the correction is half done and half a correction is a new mistake.

This is where an app changes the work rather than the rules. In Wasoolo, an entry sits on a customer, so a wrong entry is edited or deleted on that customer and written again on the right one. The edit is recorded rather than hidden, and a deleted entry goes to Trash, where it can be recovered for thirty days instead of vanishing. The balances on both sides update themselves, so you never sit with a calculator checking that two pages moved by the same amount. What does not change is the part that actually protects you: telling both people.

Telling the customer, in one short sentence

The man whose page was wrongly loaded deserves the call first. He is the one who was carrying somebody else's goods. Keep it short and take the mistake yourself.

"Nasir, I have made a mistake in my book. Rs 3,400 that belongs to another customer was written on your page. I have taken it off today. Your balance is now Rs 1,150. I am sorry."

That is the whole call. No explanation of how busy the shop was, no story about the two names. He does not need the reason and giving it sounds like an excuse. What he needs is the number he now owes and the knowledge that you found it, not him.

The second call is harder, because you are telling a man his balance just went up. Give him the date and the goods before you give him the total. "Nasir, the rice and oil and tea you took on the fourteenth had gone onto the wrong page in my book. I have put it on yours today, so your balance is Rs 9,200." Named goods on a named date are something a man can picture. A number on its own is something he argues with.

Some customers will not accept it. If he says he never took those goods, treat that as its own question, not as part of the correction. Go back to what you have: the slip, the helper who served him, the person standing next to him. If nothing supports the entry, you carry that loss and say so plainly. Insisting on an entry you cannot support costs the customer as well as the money.

Stopping it happening again

Almost every wrong-page entry comes from one of four places, and each one has a fix that costs nothing.

Similar names are the biggest. Write something beside the name that your eye catches before your hand moves: the father's name, the street, the trade, the shop he sits in front of. "Nasir electrician" and "Naseer cloth" cannot be confused at speed, and speed is when it happens.

Shared pages are the second. A father and a son on one page will always eventually be two people's goods on one balance, and then no correction is even possible because nobody can say which line was whose. Give each person his own page from the start, for the same reason that family and friends need their own lines rather than a shared one.

Writing later is the third. An entry written from memory at closing time is written from the same tired head that mixed the names up, and it is the root of most of the trouble in the udhaar you forget to write down. Write at the counter, in front of the customer, and let him see the page.

A helper writing without a rule is the fourth. If somebody else touches your book, he needs one instruction that never bends: if you are not certain whose page it is, write the entry on a slip with the name and the time and leave it for me. A slip in your hand is a small job. A line on the wrong page is a long one.

Finally, make the pages get read, and not by you alone. A shopkeeper who shows a balance while the customer is standing there anyway has a second pair of eyes on every page, and the wrong entry gets caught in a week. That habit is worth more than any correction rule here, and it is most of what keeps a khata clean over years, as keeping your khata safe sets out from the other side.

Common questions

Can I just rub out the wrong entry if I notice it the same evening?

Even the same evening, write the correction instead. It costs one extra line and it means your book has never had anything removed from it. That is worth a great deal the first time somebody questions a page.

The wrong entry is a year old and both pages have been settled since. What now?

Work out what each side actually owes today, not what the pages say, correct both with today's date and a plain note, then talk to both people. An old error left in place is the one that resurfaces in the worst argument.

The customer says he never took those goods at all. Do I insist?

Only if you have something beside your own memory: a slip, a helper who served him, a delivery. If you have nothing, say so and drop it. Insisting on an entry you cannot support costs you the customer as well as the money.

My helper wrote it on the wrong page. Should he tell the customer or should I?

You should. The customer's khata is with you, not with your helper, and the apology carries weight only from the person whose book it is. Tell the helper the rule afterwards, in private.

How do I correct it in an app, where there is no page to write on?

In Wasoolo the entry belongs to a customer, so you edit or delete it there and enter it on the right customer. A deleted entry sits in Trash for thirty days rather than disappearing, and both balances recalculate on their own.

Two of my customers really do have the same name. What do I write?

Add the thing that separates them and put it in the name itself, not in a note underneath. Father's name, street, trade, or the shop they sit near. Your eye has to catch it before your hand starts writing.
