From the phone ringing to the rupees in Tally — in one loop.

A customer rings. The sales manager opens Lumara on the second ring. Name, phone, products of interest, source — four fields, four seconds each. By the time the call ends, the inquiry is in the system with a deterministic number (INQ/2026/0124), assignable, searchable, audited. No yellow sticky note. No "I will get back to you." The customer hears, "I have noted everything, our Sales Executive will be at your place tomorrow at 11." That sentence — said in confidence on a first call — is what wins the deal.

The Sales Manager picks a Sales Executive from a list that shows who is closest, who is free, who specializes in motorised systems. The customer's address opens in Maps with one tap. The system sends an SMS to the customer with the visit time and the executive's name. No phone tag. No double bookings. The executive sees the new appointment on their phone within seconds.

The Sales Executive walks into the customer's home. Phone out. New measurement set. Add room — Hall. Width 1,540 mm. Height 1,800 mm. Mount: inside. Photo: tap, snap, attached to this exact window. Motor? Tick. Next room. The whole place takes twelve minutes. No paper. No "I will measure this one later." If the signal drops, Lumara keeps working — the measurements queue locally and sync when WiFi returns. The customer asks, "How much?" The executive shows them a price right there.

The estimate is computed from the live priced catalog. The Sales Executive shows the customer a non-binding total on the same phone they just measured with. The customer asks, "Can you do better?" The executive can apply a pre-approved discount band (up to 5%) on the spot. Anything bigger goes to the Sales Manager for one-tap approval. The customer feels heard. The deal closes warm.

The office team converts the measurement set into a formal Quotation, line-item by line-item, priced from the published catalog with GST split. The PDF is generated server-side, branded, signed digitally, and sent to the customer over WhatsApp and email with one button. The customer sees a number — typically under 8 seconds from "approve" to "delivered."

The customer accepts. The quotation becomes an Order with a new deterministic number (ORD/2026/00128). The system immediately reserves the required fabric, motors, and accessories against this order. If anything is short, a Procurement Alert fires automatically. There is no "let me check inventory and revert."

A 50% advance invoice (or whatever the org's policy says) is auto-generated against the order. CGST + SGST inside state, IGST inter-state, rounded by the rules that actually pass a tax audit. The PDF goes to the customer with the same WhatsApp + email lever. The accounts team does not lift a finger.

The system soft-locks stock against the confirmed order. Other orders cannot consume the same lot. The Production Manager sees a green tick on the order: "ready to manufacture." Procurement sees what needs to be replenished from the supplier. Nothing arrives at the bench short.

The Production Manager clicks "Generate WOs." One Work Order per item in the order — each with a unique barcode, a printed spec sheet for the bench, and a position in the queue for each stage. The shopfloor sees its day's work on a board that updates in real time.

Each Work Order moves through five stages. The Factory Operator scans the barcode at start of each stage and at end. The board updates in two seconds. The Sales team can answer "where is my order?" without walking to the floor. A defect? Scan, photo, note, the WO is held — and the Sales Manager knows before the customer calls.

The last Work Order on the order hits Dispatch. Lumara fires the Final Invoice automatically — total minus advance — with full GST treatment, the right HSN codes, and a clean signature block. It is on the customer's WhatsApp before the truck leaves the gate.

The Sales Manager assigns the install to a fitter, picking a slot from a calendar that shows the fitter's existing route. The customer gets a confirmation SMS. The fitter sees today's installs on their phone, sorted by drive time. The right fabric is at the right address at the right hour.

The fitter arrives. Fits the blinds. Tests the motor. Takes after photos — uploaded in the background even on a weak connection. Hands the phone to the customer for signature on a clean canvas. The order is marked Closed. The Sales Manager sees the photo and the signature on the dashboard within seconds.

The on-prem Tally Connector picks up the closed order and pushes the Customer, the Final Invoice, and any received payments into Tally Prime through the XML-over-HTTP bridge. If Tally is offline, the job retries. If a mapping is missing, the Accounts team gets a clear, fixable error — not a stack trace. The Friday reconciliation that used to take six hours now takes a coffee.
