The problem
What it replaces
A vehicle manufacturer selling through dealers usually runs procurement, production, dealer supply, sales, service and warranty in separate tools. Chassis and battery serials are matched by hand, dealer credit is checked after the fact, and the head office cannot see stock or sales across the network until month end.
This platform covers the whole chain: procurement and stores, production that mints serialised vehicles, credit-checked dealer allocation and dispatch, dealer sales and finance, workshop and warranty, and accounting export — with row-level tenant isolation and an offline-capable dealer app.
Who uses it
Head office
Procurement, production, allocation, approvals and accounts, with screen- and field-level permissions.
Dealers
A floor app for stock, sales, the spares counter and the service bay, that keeps working without a connection.
Customers
A self-service portal with OTP sign-in.
Website visitors
Catalogue and dealer locator published from the system; web leads flow back into it.
Features
What the system does
02
Procurement
Supplier scorecards, indents, RFQs and quotations, purchase orders and amendments, gate inward, QC, GRN, returns, debit notes and import landed cost.
03
Production and serialisation
Production orders and material issue; finished-goods receipt mints each chassis with its paired battery serial, followed by vehicle QC.
04
Dealer supply
Dealer indents, credit checks, allocation runs, dispatch with transporters, dealer GRN, GST invoices, dealer ledger, schemes and targets.
05
Dealer sales
Leads, test rides, quotes, bookings, retail invoices, registration, finance cases, pre-delivery inspection, trade-ins and campaigns.
06
Spares counter
Counter sales, returns, credit notes, back orders and online orders.
07
Workshop
Appointments, estimates, job cards with labour, parts and photos, job invoices, battery diagnostics and service reminders.
08
Warranty and quality
Policies, registrations, claims with evidence and RMA, recall campaigns, complaints with SLA and CSAT.
09
Accounts
Ledgers, payment vouchers, journals and batched export to the accounting package with ledger mapping.
10
Approvals and conversions
A rule-driven approval engine, and document conversion from indent to RFQ to purchase order and on down the chain.
11
Offline dealer floor
Sync packs and a durable mutation queue, with overcommit rejection and a list of sync exceptions to resolve.
12
Read-only AI assistant
Head office can ask questions in plain language; the assistant uses permission-checked tools and pseudonymises personal data before anything leaves the system.
Architecture
How the pieces fit together
A monorepo with one API, a head-office web app and a dealer mobile app. Tenant isolation is enforced by the database itself, not just by the application, and everything that leaves the system goes through an outbox.
