Project overview

An experience designed for performance & utility

DealBook was engineered to eliminate handwriting and paperwork risks across Pakistani car dealerships and motor showrooms by digitising vehicle sale agreements, CNIC records, biometric responsibilities, and commission calculations.

Automotive showrooms in Pakistan handle high-value transactions involving complex documentation—including seller and buyer CNIC verification, token tax status, chassis/engine matching, advance-balance tracking, and showroom HSS (Handover Responsibility) duration. DealBook provides a streamlined 5-step wizard to record deals, calculate net profit after expenses, and instantly print formal, court-admissible sale records with photos, signatures, and Urdu warranty clauses.

Business problem

Solving real operational constraints

Showroom managers traditionally relied on physical register notebooks and handwritten stamp papers. Missing CNIC copies, unrecorded extra maintenance expenses, and disputes over biometric transfer and HSS guarantees frequently caused financial loss and legal friction.

Manual books made it impossible to search previous sales by chassis number, phone number, or CNIC. Furthermore, calculating actual showroom profit across multiple partners after factoring in purchase cost, repair work, and broker cuts required slow end-of-month reconciliations. DealBook replaces this chaos with a centralized, tamper-resistant system.

User roles

Designed for seamless user interactions

Distinct interfaces tailored specifically for key user groups and administrative oversight.

Showroom Owner / Partner

Monitors active deals, tracks showroom profit, sets HSS duration, and reviews partner share reconciliations.

Deal Operator / Cashier

Enters buyer and seller details, captures vehicle specs, records advance deposits, and prints verified sale records.

Workflow

How users achieve their objectives

When a vehicle is sold or exchanged, the operator launches the Deal Wizard, entering commercial terms and payment milestones. Seller and buyer CNIC documents and photographs are attached directly to the deal file.

The system validates chassis and registration numbers against previous records, records the agreed HSS warranty window, and instantly produces a branded PDF certificate with complete legal clauses and signature fields ready for immediate printing.
