Knowledge Base

This guide explains Garage Bill—the workshop billing and operations product you use at g-billing.web.app—and how it fits your garage or service centre. It also covers how this marketing site is built, and what to expect around APIs and automations.

What Garage Bill is

Garage Bill is cloud-based software for auto repair and related workshops. It focuses on fast, accurate billing, payment tracking, spare-parts inventory, basic customer and vehicle records, expense tracking, and clear daily or periodic summaries—so owners see real earnings without maintaining parallel notebooks or spreadsheets.

What it solves

  • Cash and bill mismatch — Structured bills, payment status, and end-of-day views reduce confusion between what was invoiced and what was collected.
  • Discounts and negotiations — Discounts can be recorded consistently so revenue reflects what you actually received.
  • Spare parts chaos — Multiple brands, MRP vs selling price, and stock that updates when you bill help avoid wrong rates and stock surprises.
  • Closing-time uncertainty — Dashboards and summaries surface today's earnings, pending amounts, and trends without manual tallying.
  • Hidden costs — Expense management groups workshop spending so profit is not only revenue-based.

Who it is for

Garage Bill is aimed at:

  • Multi-brand two- and four-wheeler workshops
  • Small garages and dedicated bike shops
  • Detailing and wash studios that need simple billing
  • Spare-parts–heavy or tyre-focused outlets that bill services and parts together

It is built for owners and floor teams who want clarity without learning full accounting suites. Larger enterprises with complex ERP needs may require additional tools.

Core capability areas

The product is organised around practical workshop workflows:

  • Billing — Quick jobs, line items for labour and parts, printable or shareable bills, edits when needed.
  • Spare parts — Catalog-style entries, suggestions while billing, stock movement tied to sales.
  • Payments — Open vs paid tracking, summaries aligned with cash collected.
  • Expenses — Categories, petty cash and recurring costs, context next to revenue.
  • Dashboard & revenue — At-a-glance stats, service vs parts split, payment methods, trends.
  • CRM (lightweight) — Customers, vehicles, history to support repeat visits.
  • Reports — Daily / weekly / monthly views and exports where the app supports them.

Garage Bill web app (product)

The live application at g-billing.web.app is a separate deployable from this repository. It is a modern web app: responsive UI, secure sign-in, and cloud-backed data so you can use it on phone or desktop. The exact backend services (e.g. Firebase Authentication, Firestore or Realtime Database, Cloud Functions, or other Google Cloud components) are implementation details of that app—they communicate over HTTPS from your browser and are managed by the product team.

APIs and integrations

In-product usage — When you use Garage Bill in the browser, the client talks to backend services over encrypted HTTPS. Those calls power login, saving bills, stock updates, and dashboards. They are not a public, versioned HTTP API documented for external developers on this site.

Third-party integrations — If you need accounting exports, payment gateways, or custom workflows, availability depends on the current product roadmap. Email support@garagebill.com with your use case.

Webhooks / public REST API — A dedicated, documented public API (OpenAPI-style) is not advertised here. Treat any future announcement in-app or via official channels as the source of truth.

Automations and smart behaviour

Behaviour you get today

  • Stock automation — Selling a part on a bill can reduce on-hand quantity automatically, keeping inventory aligned with billing.
  • Suggestions — Part lookup and suggestions while billing speed up data entry and reduce typos.
  • Aggregations — Revenue, pending payments, and report rollups update from the data you enter— no separate manual consolidation for those views.

Planned: Smart Automations & Reminders

The product roadmap includes proactive features such as kilometre-based service reminders, pending-payment nudges, low-stock alerts, and customer follow-ups. These are labelled coming soon on the marketing site until they are generally available in the app—watch in-product updates for launch notes.

Security and access

Use a strong password and restrict who can log in. Owners can involve workers with appropriate access so daily billing does not depend on a single phone. For how data is handled at a policy level, read the Privacy Policy and Terms & Conditions.
