Seller OS: Multi-Tenant Operating System for Online Sellers

A multi-tenant SaaS for marketplace and D2C sellers — listings, orders, inventory, and ops workflows designed so each seller runs as an isolated tenant with shared product architecture.

This is a product built and operated by Vyuha Systems — honest portfolio work, not a fabricated client case study or performance claim.

SellerOS is a pre-launch, AI-native seller operating system built by Vyuha Systems for Indian marketplace sellers. It connects read-only to Amazon Seller Central, Flipkart Seller Hub, and Meesho, computes true profit per SKU, reconciles settlements, and surfaces money marketplaces may still owe — without silent writes to live listings.

Multi-tenant seller SaaS for listings, orders, and inventory ops. Pre-launch built product.

Why are marketplace dashboards misleading?

Seller panels show revenue clearly. They rarely show contribution margin after fees, returns, ad allocation, and COGS — and almost never show settlement gaps where marketplaces under-paid or mis-applied fee slabs.

SellerOS starts read-only: connect channels, validate the margin picture, then prioritize recovery work with evidence attached. The wedge is quantified profit and cash — not another dashboard to ignore.

What is read-only first?

Read-only first means SellerOS ingests orders, listings, inventory signals, and settlement data without migrating your stack or changing live prices. Analysis and reconciliation come before any write action — and future writes stay explicit, queued, and auditable.

Hard product rules (why sellers can trust the architecture)

Money is stored in bigint paise — never floats. Every mutation writes an audit log. Plan and feature gates are enforced server-side, not only in the UI. SellerOS is multi-tenant from day one so agencies and multi-brand operators do not require a fork.

Challenge

The situation

Online sellers rarely lack tools — they lack a system. Listings live in one tab, orders in another, inventory in a spreadsheet, and 'how we do things' in someone's head. Agencies and multi-brand operators need tenant isolation without rebuilding the product for every seller.

Approach

The system we designed

  1. Modeled the seller as a tenant: catalogs, orders, inventory movements, and team roles scoped per organization with fail-closed access.

  2. Designed the core loop around work that already happens daily — list, fulfill, reconcile stock, escalate exceptions — before adding analytics or AI.

  3. Unified marketplace-shaped workflows into one operating language so teams stop inventing parallel processes per channel.

  4. Left room for AI assists on triage and repetitive reconciliation only after ownership and handoffs were clear.

FAQ

Common questions

What is SellerOS?

SellerOS is an AI-native, multi-tenant seller operating system built by Vyuha Systems. It helps Indian marketplace sellers see true profit, reconcile settlements, and surface recoverable fee and reimbursement gaps.

Is SellerOS live?

Not yet. SellerOS is pre-launch. Request early access through the Vyuha Systems contact page while the product host is being prepared.

Which marketplaces does SellerOS focus on?

Amazon Seller Central, Flipkart Seller Hub, and Meesho are the initial read-only integrations. Shopify, Myntra, Ajio, and ONDC are on the roadmap.

Does SellerOS write to marketplace accounts?

Not by default. SellerOS starts read-only. Any future write actions to listings or prices would be explicit, queued, and auditable — never silent automation.

What does read-only first mean?

You connect seller accounts, SellerOS syncs data, and you validate profit and settlement accuracy before changing operational workflows or enabling write capabilities.

How does settlement reconciliation help sellers?

Reconciliation matches marketplace settlement statements to orders and fees, surfaces unmatched money, and ranks recoverable discrepancies so teams start with the largest rupee impact first.
