Fiado, Veresiye, Udhaar: How Shops Track Informal Credit

In Brazil and Portugal it is called fiado. In Turkey, veresiye. In India and Pakistan, udhaar. British corner shops called it buying on tick, and in German pubs the barman would anschreiben — write it up. Different words, identical practice: a customer the shopkeeper knows takes goods now and pays later, and the debt lives in a notebook behind the counter. It is one of the oldest financial arrangements in the world, it runs entirely on trust, and it never died — not when credit cards arrived, not when phones started tapping terminals. If you run a small shop, the question is not whether to allow tabs. You probably already do. The question is whether you track them well enough that they stay a kindness instead of becoming a slow leak.

Why the tab survives in a card-payment world

Informal credit persists because it solves real problems that cards cannot. Many customers are paid weekly or monthly while their needs are daily — the tab smooths the gap between an empty wallet on Thursday and payday on Friday. For the shop, it buys loyalty no points card can match: a customer who owes you 20 euros comes back to your shop, not to the supermarket. A regular who runs a 30-euro tab until payday might spend 120 euros a month with you, year after year — a 1,400-euro-a-year relationship carried by a few days of patience. And in many neighbourhoods it is simply expected: refusing all credit reads as distrust. The tab is not a relic. It is a competitive advantage that big retail structurally cannot copy.

The notebook method — and where it breaks

The classic system is a ruled notebook: one page per customer, one line per purchase, crossed out when paid. It is fast, free, and everyone understands it. It also breaks in predictable ways. The notebook is a single copy — lost, soaked, or left at home, and every balance in it is gone. Entries written in a hurry say only a date and a number, with no items, which invites disputes: the customer remembers 8 euros, the page says 12, and there is no detail to settle it. Nothing adds itself up, so nobody knows the total exposure — many owners are genuinely shocked to discover 400 or 600 euros spread across twenty pages. And usually only one person can read it, so when that person is away, credit either stops or goes untracked.

Rules that keep tabs friendly

• Set a limit per customer and stick to it — 30 to 50 euros is common for a small shop. The limit protects the friendship: you never end up resenting a good customer.
• Write the entry at the moment of sale, with date and items, while the customer watches. Shared visibility prevents most disputes before they start.
• Say the new balance out loud as you write it — 'that puts you at 26.' No surprises later.
• Agree a pay-by rhythm, usually payday. 'See you Friday' is a reminder disguised as a goodbye.
• Review all tabs once a week and total them, so you know your full exposure as one number.
• When someone reaches the limit, pause the credit, not the relationship: a kind 'let's clear this one first' works far better than avoiding the subject.

Going digital without losing the trust

The tab is a relationship first and a record second, so any digital replacement must be as fast and as visible as the notebook — or it will lose to the notebook. A spreadsheet fails at the counter; nobody opens a laptop mid-sale. What works is anything phone-first and instant: a message in a chat ('Ali plus 12, bread and milk' or 'Ali paid 30'), a shared note, or a simple ledger app. The gains are real: automatic totals, a backup that survives spilled tea, and a record that both you and your co-worker can see. Some shops keep the paper notebook for the customer-facing ritual and mirror each entry into a chat message for the totals. The ritual builds the trust; the copy protects it.

What unpaid tabs really cost

Here is the math most notebooks never show. Say twenty customers hold tabs averaging 30 euros — that is 600 euros of your cash out in the neighbourhood at all times, money that is not paying your suppliers. Now suppose 150 euros of it eventually goes unpaid this year. If your margin is around 25 percent, replacing 150 euros of lost cash takes roughly 600 euros of new sales — several good Saturdays working just to fill a hole. The point is not to abolish credit; the loyal regular worth 1,400 euros a year more than pays for it. The point is that untracked credit hides both numbers. You cannot see the exposure or the loyalty. Tracked credit lets you keep rewarding the customers who pay every Friday and quietly stop extending the two who never do.

Keep the tab, keep it written

Fiado, veresiye, udhaar — the word does not matter; the discipline does. Written at the moment of sale, visible to both sides, totalled weekly, with a friendly limit. That is the entire system, and it has kept small shops and their neighbourhoods running for centuries. The shops that get burned are almost never the ones that give credit. They are the ones that stop writing it down.
