The digital diary for neighborhood shops and the people who use them.
Connect with businesses, save offers in your wallet, and track every coupon in one place — built for you and the shops you use. Replaces paper diaries and manual credit (udhaar) tracking with a shared mobile record.
A smarter way to track neighborhood shops, credit, and coupons.
CUPN is the digital bridge between local shop owners and their customers. It helps both sides replace paper diaries and manual udhaar tracking without losing the shop relationship they already have.
Customers browse providers, connect, and pay with a wallet
Shop owners list coupons and keep promotional orders
Both see the same balance in real time
The problem
Before CUPN, the tab lived on paper
Neighborhood shops still run credit, tiffin logs, and coupons across notebooks, memory, and disputed totals.
Manual processUdhaar and daily services written by hand.
Multiple stepsSeparate slips for orders, coupons, and payments.
ConfusionShop and customer rarely share the same running total.
Time wastedRecounting diaries at the end of the day.
Missed follow-upsPending requests and offers get lost between visits.
