A receivables and payables system for J.A Paramanantham & Bros — the wholesale shop's complete who-owes-whom dashboard, with WhatsApp reminders sent from the shop's own business number, NEFT bank-payment file generation for paying vendors in bulk, and full ledger tracking down to the last invoice.
Live in production, running the wholesale business's real receivables and payables
Replaced two Excel files (SUNDRY CR LIST and LATE PAYMENTS) with one live system
WhatsApp reminders going out from the shop's own verified business number — clients receive them as messages from "the wholesale business" the same way they receive any other communication from the shop
Full reminder audit trail — every message logged with delivery confirmation, so disputes about "I didn't know" are settled in 5 seconds
NEFT bulk file generation — monthly vendor payment runs went from ~2 hours of manual bank-portal entry to 30 seconds of clicking generate
The problem, the decisions, what we built, and the parts we almost got wrong — written out in full.
