One big monthly buyer or twenty small ones?
A canteen wants a monthly account. Twenty regulars pay daily. Compare what each does to your rate, your cash and your risk before you say yes to either.

A canteen offers you Rs 120,000 a month on a monthly account. Twenty regulars already give you the same money in daily cash. The sales look identical and the two shops are not. One buys volume with your cash and your rate. The other builds slowly and owes you nothing at the end of the month.
The offer that arrives one afternoon
A man walks in around three, when the shop is quiet. He runs the canteen at a factory two streets away, or a hostel mess, or a small hotel that serves food all day. He needs a fixed list of items every week and he would rather take them from one shop.
Then come the two sentences that decide everything. He wants a rate, because he is buying in quantity. And he pays monthly, on the 10th, after the bill is passed.
Almost every shopkeeper says yes in the moment. The number is large, larger than anything the counter produces in a day, and turning down a big customer feels like the wrong kind of pride. The trouble is that yes has been given to a rate and a payment term at the same time, before either has been worked out.
So take a day. A serious buyer will wait a day. What follows is what to work out in it.
What a big monthly account is genuinely good at
Start with the honest advantages, because they are real and shopkeepers who have been burned once tend to forget them.
It is volume without crowd. One order, one delivery, one line in the book. Twenty small customers producing the same sales take a hundred separate moments of your attention, and attention is the thing a one-man shop runs out of first.
It is predictable. A canteen that needs the same list every week gives you something a counter never does: a floor under next month. You can buy against it with confidence, negotiate better with your own supplier because your quantities are steadier, and stop guessing about the slow weeks.
It also pulls your buying up a level. Larger, more regular orders are exactly what earns a better rate from the people you buy from, and that better rate applies to everything you sell, not only to his share.
And it can be a door. Institutions talk to each other. One canteen served well for a year is how the second one arrives, and the second is always easier than the first.
What it takes from you, and this is the part people skip
The same Rs 120,000 of sales, two ways
The first cost is the rate. He is not asking for a small favour, he is asking you to permanently keep less out of every Rs 100 on a large share of your shop. Work out what your normal share is before you discuss numbers with him, because a rate agreed by feel is nearly impossible to raise later.
The second cost is time, in the money sense. He takes goods all month and pays after it, so your money leaves the shop weeks before it comes back. That is the arithmetic in the next section and it is the one that closes shops, not the rate.
The third cost is who holds the terms. Twenty small customers do what your shop does: your rate, your credit limit, your collection habits. One large customer sets his own. He decides the payment date, he decides when the bill is passed, and if he is late, the polite conversation is yours to have from the weaker side.
The fourth is concentration. If a quarter of your sales is one name, that name is not a customer any more, it is a business partner who did not sign anything. The day he changes suppliers, moves the factory, or simply stops answering, a quarter of your shop is gone in an afternoon while your rent stays exactly where it was.
The number that actually decides it
Say the account takes Rs 120,000 a month and pays on the 10th
Example arithmetic, not a rule. Put in his real monthly figure, your real buying cost, and the real gap between delivery and payment.
Here is the sum almost nobody does before saying yes.
He starts taking goods on the 1st. He pays on the 10th of the following month. The first delivery therefore waits about forty days for its money, and every delivery after it is stacked behind. In the example, Rs 120,000 of monthly sales at a buying cost of Rs 105,600 means roughly Rs 140,000 of your own money is standing outside the shop at any moment.
That is the real question. Not "is he good for it", but "can I have Rs 140,000 sitting out there permanently and still pay my supplier, my rent and my helper on time?" If the answer is no, the account will not fail in month six because he cheated you. It will fail in month two because you could not restock.
If you are also buying your own stock on credit, do the sum in both directions. A supplier who gives you thirty days while your buyer takes forty leaves you funding the gap out of the counter's daily cash, which is precisely the money your household is living on.
And decide the ceiling now, in numbers: the most this one name may owe you at any moment. It is the same discipline as deciding how much any customer may carry, except the amount is ten times bigger and so is the cost of getting it wrong.

Twenty small customers, compared honestly
Small daily customers have a poor reputation among shopkeepers who are chasing growth, and they deserve better.
They pay now, or within days. The money in the drawer at closing time is money you can actually spend, and a shop that lives on same-day cash is far harder to kill than one waiting on a monthly bill.
They spread risk to the point where it stops being risk. Losing one regular out of twenty is a bad week. Losing your only large account is a bad year. Nothing else in a small shop offers that kind of protection.
They pay your normal rate, mostly without argument, because they are buying two things at a time and the convenience is worth more to them than four rupees.
Their weaknesses are equally real. They arrive one by one, so growth is slow and you must be there, every day, doing it. Many of them will want credit too, in small amounts that add up. And they are only steady if you keep them, which takes a kind of patience that no single big order requires.
The answer for most small shops is both, deliberately
Put like this, the choice looks obvious and it is not, because the useful answer is a proportion, not a side.
A big account is worth having when your counter can already pay the shop's monthly costs on its own. Then the account is genuinely extra: it raises your buying power, fills your quiet hours, and its slow payment is an inconvenience rather than a crisis.
A big account is dangerous when the counter cannot cover the costs, because then you are not adding a customer, you are moving the shop's survival onto one man's payment date.
A number worth holding: no single name should be more than about a fifth of your monthly sales, and if one drifts above that, the answer is not to drop him. It is to grow the counter until his share comes back down. Shopkeepers who have lost a large account rarely say the account was a mistake. They say they stopped working on the small customers while it lasted.
If you take it, take it on your terms
Fix these before the first delivery, not after the first dispute
- The rate for each item, written, and when it may change
- The payment date, a real date every month, not "month end"
- A ceiling: how much he may take before the old amount is cleared
- Who at his end may collect goods, and who may sign for them
- A signed or stamped slip for every delivery, kept by both sides
- What happens to returns, shortages and damaged goods
- One person you call when the payment is late, agreed in advance
The difference between a good big account and a bad one is almost entirely what was agreed in the first week.
Write the rate for each item, and the condition on which it can change, because your own buying rate will move and a rate frozen by silence quietly turns into a loss. Fix a real payment date, the 10th, not "month end", and put it in writing where both sides can see it.
Get a slip for every delivery, signed or stamped by whoever received it. This is not distrust, it is how large buyers work internally: the man who receives goods is rarely the man who passes the bill, and a month later the only thing that settles a question is paper. Keep your copies in order, because a monthly account without delivery records is an argument waiting for a date.
Then keep the running balance somewhere both of you can look at. A monthly statement he receives without asking prevents nearly every dispute, and a shop that keeps its accounts in Wasoolo can produce that statement for a single customer in a minute, with the shop's own name on it. Whatever you use, send it before the payment date, not after it.
For a very large account, ask yourself the harder question too: if this ends badly, what do you actually have? A signed order, a set of stamped delivery slips and a clear statement is a real position. A verbal arrangement with somebody's manager is not, and that is when asking for a guarantor stops being awkward and starts being ordinary business.
What to do when the big one goes

Assume it will end. Managers change, contracts are re-tendered, a factory closes a shift. None of it is personal and all of it arrives without warning.
The shop that survives it is the one that kept doing three things while the account was healthy. It kept serving the counter properly instead of treating small customers as an interruption. It kept a second and third account of its own, so no single loss took more than a fifth. And it put some of the account's own money aside rather than letting the larger monthly figure quietly raise the household's spending.
There is also a warning worth watching for. Late payments that creep from the 10th to the 15th to "next week" are the first honest signal you will get, long before anybody says anything. The moment a large account starts paying late, tighten the ceiling and slow the deliveries. It is far easier to hold a balance at Rs 60,000 than to recover Rs 200,000 from an institution that has stopped answering, and shops that ignored the drift are the ones that end up with a number they cannot collect and no goods to show for it.
Handled with those rules, a big monthly account is one of the best things that can happen to a small shop. Handled on a handshake and a good feeling, it is the single fastest way to hand a stranger control of your year. The decision was never big customer or small customer. It was whether you set the terms or he did, and whether the shop underneath could stand on its own either way. That is also why the rhythm of your collections matters more once a large name is on the books.
Common questions
He wants a rate I am not comfortable with. Do I walk away?
Work out what you keep out of Rs 100 at his rate first. If it still covers a share of your monthly costs and you can fund the wait, it may be worth taking, because the volume also improves your own buying. If it leaves you keeping almost nothing, the account is buying your time and cash for free, and a polite no costs you nothing but one afternoon.
Should I give a big account a credit limit like a normal customer?
Yes, and more strictly, not less. The limit is the most he may owe at any moment, and it should reflect what you can survive losing rather than what you hope he is good for. Tell him the number when you agree the terms, so that pausing deliveries later is a rule you both knew about instead of an insult.
What is a fair payment gap for a monthly account?
Whatever both sides agree and can actually meet, but the shorter the better for you, and a fixed date beats a vague one every time. Many small shops do better with two half-payments a month than one at the end, because it halves the money standing outside the shop and shows a problem four weeks earlier.
How do I say no without losing him for the future?
Say no to the terms, not to him. Tell him what you can do: this rate at this payment date, or his rate if he pays fortnightly. Buyers respect a shopkeeper who knows his own numbers, and a clean no is remembered better than a yes you cannot keep. Quite often he comes back having found that the cheaper supplier delivers short.
He pays late every month but he does pay. Is that fine?
It is a cost, so price it or fix it. Being paid three weeks late every month means more of your money is permanently outside the shop, which is the same as lending it to him. Ask for a date that matches when his own money actually arrives, and hold the deliveries the first time it slips, calmly, before it becomes the normal habit.
My counter is quiet and this account is the only growth available. Then what?
Take it, but take it small. Start with half of what he asked for, keep the ceiling low for three months, and watch how he pays before you grow it. A big account that begins carefully can always be expanded, while one that begins at full size and goes wrong takes the shop's whole working money with it.
