Billing for your mobile and electronics shop in Sikkim
Room heaters before the first cold week, a warranty slip that cannot be lost, and string lights by the metre.
Room heaters that sell out in the first cold week, a warranty paper gone missing, and a cable for every port
The first cold week sells every room heater in the shop
An electronics shop in a hill town sells handsets all year, and in the first properly cold week it sells every room heater and blower it has. They are few, costly and bulky, and the next lot comes from the plains. The owner finds out he is out of heaters when the third customer of the morning asks for one. By then the customers who came for a heater have walked to the next shop, and they buy the blower there as well.
The warranty paper that goes missing
Before the guests come, a homestay owner buys a kettle for each room and a heater for the cold ones, and the shop stamps one paper slip for the lot. Months later a kettle fails in the middle of a full house. He walks down the lane and asks you to show which one was his. The stamp has smudged, the slip names no model, and your bill book has no name in it.
A cable for every port, and the customer who knows only the shape
A car from the plains stops at the shop and the visitor's phone has died on the way up. He needs a cable and a plug that fit, and he does not know the port. You try three cables while the driver waits with the engine running. The cables hang in one bunch, counted by guess, and the one that fits most phones is always the one that has run out.
MG Marg, where a visitor in the cold asks for a charger and a heater
A mobile and electronics shop sells to people on the move, and a busy street is where a charger or a heater is suddenly needed.
- MG Marg in Gangtok is a one-kilometre vehicle-free shopping street, popular for Sikkimese handicrafts, prayer wheels and flags, with food stalls and cafes.
Tools for a counter of handsets, heaters, kettles and lights
Orders to suppliers
Heaters and blowers are ordered a week before the cold, as no supplier shortens the wait, and each arrival is noted.
Low stock warnings
A warning when the room heaters and blowers fall to the line you set, a few days before the first cold week. A heater that sells only in the cold shows as a flat line the rest of the year, and the line comes down.
Daily reports
The heaters a homestay buys before its guests come, set beside the heaters families buy in the first cold week, so the shop orders for each from what really went.
Heaters counted before the cold, a handset's earlier repairs on its owner's page, and cables named by their port
The small room heater and the big blower counted apart
Make the small room heater and the big blower two items, each with its own count. A homestay owner who takes six small heaters before the guests come takes six off one count, and the blower count stays as it was. In the first cold week you see which size is running out, and order that size.
A handset's earlier repairs on its owner's page
Each repair is billed to the owner's page with the date and the part. When the same handset comes back with a fault, you open the page and see what was done, when, and whether the new fault is the old one returning.
The long drive's cable, plug and power bank, three items on one bill
Make the cable, the car plug and the power bank each its own item with its own count. A car from the plains stops for the three before the long drive towards Nathu La, and one bill takes all of them, each count coming down by one. The one that is missing most often shows at the top of the list.
Questions Sikkim mobile and electronics shops ask
The stamp on the kettle's warranty paper is smudged. What proves the date?
The homestay's page names each kettle's model and the date of its bill, so the smudged stamp stops mattering, and the bill sent to his WhatsApp at the time shows the same line.
The heaters I ordered for a homestay have not come on the cold morning. What do I tell the owner?
Ask which rooms have guests tonight and send the heaters you hold there first. Make one bill in the homestay's name for those, and a second under the same name when the rest arrive.
A homestay bought a lot of kettles and one has failed. What do I do with the lot?
Keep the failed kettle as a separate item so it is not sold again, and give the homestay the same model. Its page shows the lot's size, so you know how many to check.
A customer asks for a charger and a cover for a handset I do not stock. Can I note it?
Yes. Put the model on your order to the supplier when you are asked, and the list will carry what customers really wanted. Names asked for twice in a month are the ones to stock.
