A billing and accounts app for a trading business. Invoices go out from a phone in seconds, payments are matched automatically, and the owner sees who owes what without opening a notebook.
The challenge
A trading business tracks invoices in spreadsheets and dues in a notebook. The owner can't see who owes what without hours of checking.
What we'd build
- Designed invoice creation for speed on a phone.
- Built the billing and payment flow around how the business already works.
- Built an at-a-glance dashboard of balances and overdue payments.

Pick the client and items, and send a GST-ready invoice on WhatsApp or email.
Dues at a glance
Every client's outstanding balance and how long it has been due.
Payment reminders
Polite automatic reminders for overdue invoices, with a UPI link.
Daily summary
Sales, collections and dues sent to the owner every evening.

What we'd use to build it. The final choice depends on your needs and the systems you already use.
