The AI-powered commerce
operating system.
Sellaris unifies catalog, inventory, orders and pricing across every channel you sell on — then layers AI on top to find what to sell next, price it correctly, write the content and forecast the demand.
One system of record for your whole operation
Most sellers run on a patchwork of spreadsheets, seller panels and courier dashboards. Sellaris replaces that with a single tenant-isolated platform where every product, order and rupee reconciles.
Catalog & listings
One product record, many marketplaces. Attribute mapping, A+ content, bulk edits, and per-channel listing health.
Inventory & warehouses
Multi-warehouse stock, GRN and put-away, damage and adjustment trails, low-stock and reorder alerts.
Orders & fulfilment
Unified order pipeline with courier allocation, label generation, NDR/RTO handling and SLA tracking.
Finance & GST
Settlement reconciliation, P&L, cashflow, expense capture and GST-ready invoicing and filing reminders.
D2C storefront
Your own branded store with a drag-and-drop section builder, coupons, payments and WhatsApp commerce.
Integrations
Marketplace, courier, payment and messaging integrations with encrypted credential vaulting and retry queues.
AI that does the work, not just the chat
Every AI surface in Sellaris is wired to real operational data and can act through approval-gated workflows — so recommendations become changes, safely.
Trend Scout
Discovers emerging products from marketplace bestsellers, search trends, social signals and crowdfunding — ranked, deduped against your catalog, and traceable to sources.
Dynamic repricing
Rule-based and AI-assisted repricing with Buy Box awareness, margin floors, price-war detection and human approval above configurable thresholds.
Content generation
Titles, bullet points, descriptions and A+ modules generated per marketplace, respecting each channel's content rules.
Forecasting & anomalies
Demand forecasts that drive reorder points, plus anomaly detection on sales, returns and settlement variance.
Live in days, not quarters
Connect your channels
Link marketplace seller accounts, couriers and payment providers. Credentials are encrypted at rest and scoped per tenant.

About Happynas World
Happynas World is a registered partnership firm based in Mumbai, India. Sellaris is our commerce platform — the product we build, operate and sell.
We started as operators running our own multi-channel e-commerce business and kept hitting the same wall: the tooling either handled listings or inventory or finance — never the whole operation, and never with intelligence attached. So we built it.
Sellaris is now the commerce operating system we wanted: one tenant-isolated platform where catalog, stock, orders, pricing and money reconcile, and where AI is wired into real operational data rather than bolted on as a chatbot. We also run our own D2C storefront on it — proof the platform works in production.
