Breakdown: The Four Cost Tiers

Single-store retailer — ₹20,000 – ₹70,000 one-time · ₹6,000 – ₹15,000/year ongoing Multi-store SME chain — ₹1.5L – ₹5L one-time · ₹36,000 – ₹1.2L/year ongoing Omnichannel D2C brand — ₹8L – ₹25L one-time · 15–20% of build/year ongoing Enterprise retail chain — ₹25L – ₹1 Cr+ one-time · 15–20% of build/year ongoing

What Drives the Jump Between Tiers

Store count and channel count matter more than revenue. A single ₹50L-revenue boutique brand selling only on its own website stays in Tier 1–2 territory, while a ₹5 Cr-revenue brand live on four marketplaces and two stores is already deep in Tier 3 — because the integration surface area, not the revenue, is what drives the engineering cost.

How to Decide Which Tier You're In

Staff manually reconciling stock between locations or channels → you're past Tier 1. Approaching or above ₹5 Cr AATO → confirm GST e-invoicing (IRN) support now. Overselling across 3+ channels → you need a real OMS (Tier 3). No single system shows total stock + orders + customer history across channels → that's usually the highest-ROI next build.
