A qist plan for a customer who already owes you
He has an open udhaar balance and now wants a big item on instalments. Keep the two apart, shrink the old page first, and size the plan honestly.

Keep the two apart. The old udhaar stays on its own page and gets its own small fixed payment; the new plan stands alone with its own down payment and dates. Add both monthly amounts together before you agree anything, because that total, not the plan alone, is what he has to carry every month.
Rs 9,000 on his page, and now he wants a fridge
Naeem has been on your khata for two years. His page sits at Rs 9,000, which is normal for him: it goes up mid month, comes down after he is paid, never quite reaches zero.
Now he is standing in front of a fridge you can arrange for Rs 62,000 and asking for a qist plan. Twelve months, he says. He will manage.
Two answers are wrong here. The first is a quick yes, because he is a good customer and the fridge is a good sale. The second is a quick no, because he already owes you money.
The right answer is arithmetic, and it takes four minutes. What is he carrying now, what would the plan add, and can one household pay both in the same month without one of them quietly failing?
Do not fold the old balance into the plan
The first instinct is to make it tidy: add the Rs 9,000 to the fridge, call it Rs 71,000, and run one plan. It looks simpler. It is the mistake that breaks these arrangements.
Three reasons, and each one bites later.
The plan is tied to an item you sold at a price you agreed. The old balance is groceries eaten months ago. Once they are mixed, neither of you can ever say what a payment was for, and the day there is an argument, there is nothing to point at.
Second, the old balance can be settled fast if he has a good month, while the plan should not be. Mixed together, he loses the freedom to clear the small one and you lose a clean page.
Third, and worst, if the plan breaks and the item has to come back, you cannot work out what belongs to the item and what belongs to old groceries. Untangling that is misery, and it starts the moment a payment slips, which is where a missed qist payment begins.
So: two records, two dates, two conversations. Tidy is not the same as simple.
One customer, two arrangements, kept apart
Keep it this way
- The old page keeps its own balance and its own small fixed payment
- The plan has its own dates, its own instalment and its own record
- A limit on the old page that does not move while the plan runs
- Two payment days in the month, so he can keep them apart too
- Look at the combined total every month, not one at a time
Not this way
- Adding the old balance into the item's price to make one plan
- Letting the old page grow freely while instalments arrive on time
- Taking a payment without saying which of the two it is for
- Stretching the plan long just to make the instalment look small
- Adding anything on top because a payment came late
Work out what he can actually carry
Say it plainly to yourself before you say anything to him.
Say his page is Rs 9,000 and the fridge is Rs 62,000 over 12 months
His old page is Rs 9,000 and he brings about Rs 4,000 a month against it while adding roughly Rs 3,500 of new groceries. That page is not shrinking, it is breathing.
Now add a fridge at Rs 62,000 over twelve months, which is Rs 5,166 a month before any down payment. His shop money now has to find Rs 4,000 for the old page plus Rs 5,166 for the plan, and still buy the groceries he was buying anyway. That is over Rs 9,000 a month leaving one household towards one shop.
If that is genuinely within his income, the plan is sound. If it is not, you have just discovered it in four minutes instead of in month five, and everything that follows is about making the arithmetic fit rather than hoping.

Shrink the old page before the plan starts
The cleanest arrangement starts with the old balance smaller, and there are three honest ways to get there.
Settle it at the start. He pays the Rs 9,000 off, or most of it, before the plan begins. Many customers can do this if given two or three weeks of notice, especially if they want the item.
Fold it into the down payment conversation. He is going to hand you money on day one anyway. Ask for a down payment that clears the old page as well as opening the plan. Same money, but now the page is at zero and the plan starts on clean ground.
Freeze it and pay it flat. If neither of the above is possible, agree a fixed small payment on the old page, say Rs 1,500 a month, and no new credit on that page while the plan runs. He knows exactly what he owes and where, and the balance actually falls instead of breathing.
What you should not do is leave the old page running exactly as it was, open and growing, while a plan starts beside it. That is two open pipes and one income.
Sizing the plan so it survives
Now build the plan itself, remembering everything you already know about him.
Down payment. Take more than usual here, not less. A larger first payment lowers every instalment and removes the temptation for both of you to be optimistic. A customer already carrying a balance who cannot manage a decent down payment is telling you the plan is too big.
Length. Longer looks kinder and is often crueller: more months for something to go wrong, and a longer time before the item is truly his. Match the length to the item's own life, not to the smallest instalment you can imagine.
The price. If you add a markup for selling on instalments, it is a one-time amount, set and agreed when the plan is made, and written into the total. It never grows because a payment is late, and nothing is ever added for lateness. Say the total price out loud before he signs anything, so there is no surprise in month three. The whole shape of a fair plan is set out in how to build a qist plan.
The dates. Put the instalment date a day or two after his income day, and put the old page's small payment on a different day of the month. Two dates, two envelopes in his head.
A guarantor, if the number is large. For a plan on top of an existing balance, this is more reasonable than usual, and it is not an insult if you say it as a rule about amounts rather than about him.
When the daily credit starts slipping again
Here is the failure that actually happens. The plan is paid faithfully every month, and the old page starts growing again, because he still needs groceries and you are still writing them down.
Watch for that specifically. The plan feels healthy while the total owed climbs, and both of you feel fine until the day the total is suddenly frightening.
Two rules prevent it. The old page gets a limit that does not move while a plan is running. And you look at the combined number, plan plus page, not one at a time. If the combined number is rising, the plan is not affordable no matter how punctually the instalments arrive.
If a payment is missed, deal with the plan and the page separately, and start with the plan, because it is tied to an item and has a schedule. Big items are worth thinking about this way from the beginning, which is the argument in udhaar or qist for a big item. Ask for the amount that was actually due, not the whole balance. And when you decide his ordinary credit limit, use the same thinking as how much udhaar to give, with the plan counted as money he already owes you.
Keeping both records straight
Two separate arrangements with one customer are exactly where paper registers become confusing, because both live under one name.
In Wasoolo the qist plan sits as its own khata with its own schedule and its own instalment history, while his ordinary udhaar page stays where it was. You can see both under the same customer without them mixing, so a payment always lands on the thing it was meant for.
The plan's dates are the useful part. Each instalment has a date, so you can see what was paid and when, and the customer's own reminder comes from that schedule: a notice on his own login if he uses the customer app, plus a one-tap button that opens a WhatsApp chat with the figure ready for you to send.
When the total price includes a one-time markup you agreed at the start, that amount is recorded once as part of the plan, so the balance he owes is the balance you both agreed. And a printed statement of either record settles any argument in one sheet, which is worth more here than anywhere, because a customer carrying two things with one shop is the customer most likely to lose track.

Common questions
He is a good customer and my saying no would insult him. Can I not just trust him?
You can trust him and still do the arithmetic, and it is better to do it in front of him. Show the two monthly amounts side by side and ask him whether that fits his month. Most customers respect that far more than a quick yes, and quite a few will choose a smaller item themselves once they see the total.
Why not merge the old balance into the plan? It is the same money.
It is the same money but not the same thing. One is tied to an item at an agreed price with a schedule, the other is groceries from months ago. Merged, you cannot say what any payment was for, the small balance cannot be cleared quickly on a good month, and if the item ever has to come back, nobody can untangle the two.
What if he cannot manage a down payment because his money is going to the old balance?
Then take that as the answer for now. Let him clear the old page over a few weeks, keep the item aside if you can, and start the plan when the page is at or near zero. A plan that begins with no down payment on top of an existing balance is the one most likely to break.
Should I stop his daily credit while the plan runs?
Stopping it completely usually pushes him to another shop and costs you the customer. Cap it instead: a fixed limit on the ordinary page that does not move while the plan runs, and no exceptions in the middle of the month. He keeps buying, and the total stops creeping.
He wants a longer plan so the monthly amount is smaller. Is that helpful?
Only up to a point. A longer plan means more months in which something can go wrong, and a longer time before the item is fully his. If the only way the numbers fit is by stretching it to a very long plan, the honest answer is usually a cheaper item or a bigger down payment.
He missed one instalment but paid his grocery balance. What does that tell me?
That he is paying whichever one feels more urgent, which is usually the one where he faces you daily. Fix it by talking about the plan first, agreeing a date for the missed amount, and holding the ordinary page at its limit until the plan is current. Never add anything on top for the delay: it turns a payment problem into a fight and does not get you paid faster.
