Executive Summary

Small businesses using TallyPrime often send invoices by email or paper and then wait days or weeks for payments, creating cash-flow and reconciliation friction for millions of merchants; this manual chase is a recurring pain for roughly 5 million addressable SMBs. The lack of a reliable, immediate customer channel means invoices are ignored or paid late, increasing working capital strain. You could build a lightweight connector that automatically pushes TallyPrime invoices, payment links, and status updates over WhatsApp using the Cloud API/BSPs, with configurable templates, read receipts, retry rules, and ledger reconciliation back into Tally. The product would prioritize one-click payments, opt-in management, and low-friction onboarding so non-technical accountants can activate it in hours rather than weeks. This is timely: the addressable market is approximately $3.0B (5M SMBs × $600 ACV), market health scores at 88/100 and revenue potential at 78/100, and messaging-first communication yields materially higher open/action rates than email—accelerating collections and conversion. SMB digitization and mature WhatsApp Cloud APIs lower the implementation barrier, making go-to-market practical now. You can stand out by offering deep, certified TallyPrime integration, simple onboarding, and pricing tailored to cash-strapped SMBs, rather than generic messaging platforms. Be upfront about challenges—WhatsApp policy/opt-in requirements, per-message costs, and integrations at scale—but with medium competition and clear ROI (faster collections), this is a pragmatic, defensible opportunity worth validating.
