The problem

A doorstep car wash business depends on dozens of washers working across the city every morning, recurring customer subscriptions, and tight daily coordination. Running it on spreadsheets, WhatsApp groups and phone calls made it hard to verify that every scheduled wash happened, track washer attendance in the field, calculate incentives fairly, and close payroll and GST each month. The founder had no single, reliable view of the business.

What we built

One connected system, with a dedicated app for every role in the company:

• Customer booking and payments: customers choose a plan, book and pay online through Razorpay, and receive an automatic WhatsApp message with a live link to track their washer.

• Washer app: daily job list, GPS-verified check-in at the customer's location, before/after photos and job history.

• Supervisor and manager apps: live field tracking, attendance, rescheduling, complaint handling and escalation alerts when jobs run late.

• Sales and telesales CRM: lead capture, lead assignment, follow-up deadline tracking and demo scheduling.

• HR and payroll: employee onboarding, attendance and leave, statutory deductions, and an incentive engine that calculates each washer's payout automatically.

• Inventory and procurement: barcode/QR stock tracking, material issued to each washer, and month-end stock verification.

• Finance and GST: automatic accounting entries, P&L, balance sheet and GST-ready reports.

• Founder control tower: a single dashboard showing revenue, jobs, staff and profitability across every team.

How we worked

We followed Genxa's prototype-first process. A working prototype of the core booking and washer flow was shown to the founder in person before any commitment. After that, each module was built, tested with the team in real day-to-day use, and refined before the next one was added, so the business could start benefiting early instead of waiting for one big launch.

The outcome

Every part of the business, from a customer's booking to the washer's check-in, the month's payroll and the GST return, now runs on one platform. Managers see what is happening in the field as it happens, incentives and salaries are calculated by the system instead of by hand, and the founder has one place to see how the business is performing.
