Executive Summary

Around 20 million Indian SMBs still rely on manual or semi-digital processes for billing, inventory and GST filing, which creates frequent errors, compliance risk, time-consuming reconciliation and delayed payments that eat into margins and cash flow. Accountants and business owners both spend too much time on routine filing and correcting mismatches, and many SMBs risk fines as e-invoicing and GST controls tighten. You could build a mobile-first, cloud invoicing + inventory system with built-in GST automation and e-invoice/GSTN integrations, automatic bank/UPI reconciliation, offline support and an accountant-facing portal — offered at an annualized price point in line with the $300 ACV benchmark. The product should prioritize simple onboarding, multi-language support and a payments flow that accelerates cash collection for merchants. This is a compelling market right now: roughly $6.0B in addressable spend (20M SMBs × $300 ACV) and accelerating regulatory tailwinds (e-invoicing, stricter reconciliation) plus near-ubiquitous smartphone and UPI adoption to support mobile-first adoption. Accountants are actively migrating clients to SaaS tools, which provides a trusted distribution channel that can lower CAC. You can differentiate by owning deep GST/e-invoice automation (pre-built GSTN/e-invoice connectors), tight payments reconciliation and an accountant-partner program to drive trust and onboarding at scale. Expect tough competition and unit-economics pressure from incumbents and low willingness-to-pay, so mitigate risk with early accountant partnerships, focused vertical pilots and measurable ROI for merchants (time saved, fines avoided, faster payments).
