Illustrative preview — explore the real thing in the live demo below.
Everything a garage needs, in one place
No modules to configure, no separate billing software — one app covers the whole customer-to-cash workflow.
Dashboard
Live counts for customers, vehicles and active jobs, today's and this month's revenue, and your 10 most recent job cards at a glance.
Customers
Instant search, a duplicate-mobile-number warning, and a full profile with every vehicle, job and rupee billed to each customer.
Vehicles
Uppercase-normalised vehicle numbers, bike/car filters, and a complete service history for every vehicle you service.
Job cards
Auto-numbered job cards, a searchable vehicle picker that fills in the customer, live-calculating totals, and one-tap status changes.
Invoices & billing
Spare Parts / Labour / Service bifurcation, editable tax & discount, Paid/Pending tracking, and a pixel-matched PDF download.
WhatsApp sharing
One click opens WhatsApp pre-addressed to the customer with the invoice link, plus one-click payment reminders. No paid API needed.
Import past data
Bulk-load existing customers and vehicles from a spreadsheet, with duplicate detection and back-dated job/invoice history.
Settings & team
Business details, logo, document numbering, tax rate, session timeout and staff logins — all from one screen.
From walk-in to WhatsApp, in six steps
The same flow every garage already follows — just faster.

Frequently asked questions
Do I need to install anything?
No. WrenchBook runs in the browser on any phone, tablet or computer — nothing to download.
What does the WhatsApp sharing cost?
Nothing by default — it uses the free wa.me click-to-chat link. Direct PDF delivery via the paid WhatsApp Cloud API is supported too, if you want it later.
Can my staff have their own login?
Today it is a single owner login per garage, by design, to keep things simple and secure. Multiple staff logins can be enabled if you need them.
Is my data safe?
Yes — PostgreSQL storage, bcrypt password hashing, signed HTTP-only session cookies, and soft-deleted (never hard-deleted) records so your billing history is preserved.
