Billing for your hardware and paint shop in Punjab
A lock and its spare key, a roll of fencing wire and a welder's gate, each written down on your phone.

Why a Punjab hardware shop sells a lock and its key, a roll of wire and the iron for a gate
A lock sold today, a spare key asked for next month
A customer buys a lock for a new gate or a shed, and a few weeks later he is back for two spare keys. Cutting a key is a few minutes of work and a blank, and you charge a few rupees that go into the drawer with no line. The lock, the key and the customer are three things that nobody can find in the notebook later. And the customer remembers the day he paid for the lock better than you do.
A field's fencing: posts, wire and staples bought on three different days
Farmers fence their fields and their cattle yards, and a fence is posts, a roll of barbed wire and a packet of staples, bought in pieces over a week as the work goes on. Each visit is a separate slip. When the farmer's brother asks what the fence cost, the three slips are not in one place.
The welder's gate, with iron on credit and a paint pot to match
A welder who makes gates and grills for new houses takes angle iron, sheets, pipes and rods from you through the week, and settles when the owner of the house pays him. The same house wants the gate painted red oxide and then a final colour. The iron, the rods and the paint all belong to one gate, but in your notebook they are four entries on four days.

Bills on your phone
A bill with a lock, two spare keys cut at the counter and a packet of screws, each line with its own rate.
Credit book (khata)
A page for the farmer who puts up a fence in stages, posts one day and wire the next, each line dated, read off the page when he pays.
Daily reports
How many locks, keys and rolls of wire went on each day, so the weeks before the sowing and before a wedding season can be compared.

Machine tools, sheesham wood and sand behind a Punjab hardware shelf
A hardware shop in Punjab draws on the state's machine tools, its timber and its building sand.
- Ludhiana's biggest industries are hosiery and textile, followed by cycles, cycle parts, machine tools and auto parts.
- Hoshiarpur is known for sheesham wood inlay furniture and lac turnery; around 100 to 150 artisans practise the inlay craft.
Questions a Punjab hardware shop owner asks
Every spare key uses a blank. How do I count the blanks used against the keys I cut?
Keep the blank as an item with its own count, and key cutting as another item with its charge. Each cutting bill takes a blank off the count, so the blanks left on the phone match the keys cut, and the bill sits on the customer's page beside the one for the lock.
The farmer's brother asks the total cost of the fence: posts by number, wire by the roll, staples by the packet. How do I give it?
A brother or co-owner asks what the shared fence cost. Posts, wire and staples are each an item in its own unit, and the fence's page adds the lines to one total, with the three lines behind it.
The house owner chose the top colour from a card. Where do I write the colour against the gate?
The welder carries the owner's colour card to your counter. Write the colour, top colour, deep green, against the house's name on his page, so when the gate is painted again the page has the card's colour and the name of the house.
Sand from three states, and Batala's shut workshops
In December 2022 the Tribune reported that sand and gravel sold in Punjab was being brought from Himachal Pradesh, Haryana and Jammu and Kashmir. A hardware shop that sells sand or gravel can note each lorry as it arrives, with the day and the rate.
In Gurdaspur district, Batala has lost 60 per cent of its industrial units, and a report in August 2026 called revival a distant hope. A hardware shop there keeps a page for each fabricator and foundry that still orders, with the iron and rods taken and the days, because those few workshops are now its bulk buyers.
