RetailDA™ — One ledger. Every site, entity and country.

Q: Does it really work when the internet drops?

Not offline mode — offline-native. Checkouts, ledgers and tax logic execute on the terminal; the cloud is a replication target, not a dependency.

Built for groups consolidating many systems onto one

Resilience, measured across every site

Lost internet. Keep selling.

Across two hundred sites, something is always offline: a leased line, a router, a monsoon. RetailDA™ treats connectivity as optional. Checkouts, ledgers and tax logic execute locally and reconcile upstream in order when the link returns. Try it: pull the plug.

AI & RAG · entity-scoped

Ask the business a question. Get an answer with the receipt.

Generic AI guesses about your business because it has never seen it. RetailDA™ indexes your own operational record: catalogue, stock, pricing, suppliers, contracts and policy. Answers come from that, cite the row they came from, and respect who is allowed to see them.

Grounded retrieval

Answers drawn from your catalogue, ledger, contracts and SOPs, with the source record cited. Short on data? It says "not enough to act on" — instead of hallucinating.

Agents that can act

An MCP surface your own agents operate, inside the same permission model as your staff.

How the RAG layer works →

Document intelligence

Supplier invoices, POs and contracts extracted into structured records that feed the index.

Governed and capped

Entity-scoped access, no third-party training on your data, per-user token and cost ceilings.

The catalogue

55 apps. One platform. One contract.

Most groups arrive running four or five systems that were each the right answer at the time. RetailDA™ is one system where every app already shares the same catalogue, stock ledger, customer record and audit trail, so consolidation is a migration rather than an integration programme.

Frequently Asked Questions

An operating system for retail and industrial operations — 55 offline-first apps on one ledger: POS, inventory, kitchen, hotel PMS, AI and industrial control. Turn on a single register or deploy the whole suite; the rest stays invisible until you need it.

AI Delta OS starts at ₹999/site/mo billed yearly (₹1,299/mo · $19/mo · ₹29,999 one-time perpetual) — billing, stock, storefront and the AI agent in one closed runtime. Growth (₹2,999/site/mo · ₹99,999 perpetual) unlocks the 28 modular apps; Scale (₹7,999 · ₹2,49,999 perpetual) adds the AI Engine plus one Vertical Suite free. Upgrades land in one click on the same database — model your sites in the estimator.

Not "offline mode" — offline-native. Checkouts, ledgers and tax logic execute on the terminal; the cloud is a replication target, not a dependency. See the engine →

Over 18,000 licences shipped as WeBFooT® since 2020 — including a 7-outlet, 97-terminal retail network since 2021, three air-gapped defence & PSU canteen and supply operations, field-custody stock at a national institute and SCADA-driven water plants on the same binaries and ledger. A manufacturer lost ₹20L in 48 hours; not a unit has gone missing since this stack went in. Case studies →

Wherever you decide — multi-tenant cloud, your private cloud, or fully air-gapped on your own hardware. Same product, same pricing model; managed hosting on TolsTek Sovereign Host is separate. Deployment models →

Yes — guided migration with a sandbox, bulk import and a named implementation lead from the Scale plan up. Catalogues, customers and opening stock come across; the compare page shows per-app edges against the incumbents.

One site, one price — staff accounts, registers, SKUs and transactions unlimited on every paid plan. A 100-terminal store doesn't multiply the licence; fleets take −10% at 10+ sites and −20% at 25+, and the estimator plus the compare page run the five-year math against per-seat suites.

A guided evaluation, not a forever-free tier: a real register, stock ledger and fiscal documents on a guided demo or sandbox — no card. Start the trial or book a demo on your own catalogue.
