Unify your commerceWhy retailers in India choose open-source commerce
Retail breaks when stock is a guess. When each store, the warehouse, and the website count inventory separately, you get stockouts on the fast movers and dead cash in the slow ones — and staff waste hours reconciling. The fix is one source of truth: POS sales and online orders draw down the same live inventory, reorder rules fire on time, and every channel reports into one system.
Proprietary retail platforms deliver this, but they charge per till, per user, or a cut of every sale — a tax that grows as you add stores. An open-source stack — ERPNext for the back office and Medusa.js for the storefront — carries no per-user or per-order fee, and you own the catalogue, orders, and customer data.
Mith Tech builds this unified commerce stack for Indian retailers: multi-store inventory and GST on ERPNext, a headless Medusa storefront, and automated loyalty. See the commerce solutions or read our open-source Shopify alternative guide.
Retail & commerce software — frequently asked questions
What is the best software for a multi-store retail business in India?
The best fit for most Indian retailers is an open-source commerce stack — ERPNext for back-office inventory, purchasing, and GST, connected to POS and a headless online store — so in-store and online share one source of truth. This unifies stock across stores and channels with no per-user licence fee, and you own the data instead of renting a SaaS platform.
How does retail software reduce stockouts and overstocking?
Software prevents both by keeping stock accurate in real time across every store and channel. When POS sales and online orders draw down the same inventory, reorder rules trigger before you run out, and slow lines are visible before they pile up. One synced system replaces the spreadsheet counts that cause stockouts on fast movers and dead cash tied up in overstock.
Can I connect my POS, online store, and inventory in one system?
Yes. ERPNext acts as the retail back office — multi-store inventory, purchase orders, pricing rules, and GST invoicing — while POS terminals and a headless storefront feed it live sales. Every channel updates the same stock and customer data, so a sale in a store and an online order never fight over the same unit, and reporting covers the whole business at once.
Is retail ERP software expensive?
Proprietary retail and POS platforms charge per till, per user, or a percentage of sales, so cost rises as you add stores and staff. Open-source ERPNext plus Medusa is a one-time implementation plus hosting, with no per-user or per-order fee. For a growing multi-store retailer, that model is far cheaper over three years and avoids SaaS lock-in.
Does the system handle GST invoicing across stores?
Yes. ERPNext generates GST-compliant invoices natively across all stores — with correct tax, HSN codes, e-invoicing, and e-way bills — from live sales data. Each store or entity can carry its own GSTIN, and returns draw from one system rather than consolidating separate tills. This keeps multi-location GST filing accurate without re-keying between POS and accounting.
Do you build a custom online store connected to my inventory?
Yes. Mith Tech builds high-performance headless storefronts on Medusa.js, connected to ERPNext for inventory, orders, and GST, so your website and stores share one catalogue and one stock pool. The store is yours — no per-order platform fee — and product data, orders, and customers flow into the same system that runs your physical retail.
