Description

Solution Garage and car-service management software

WavX builds garage management software for workshops, multi-brand service centres and detailing studios: job cards, digital inspections, estimates the customer approves on WhatsApp, parts stock, mechanic allocation, GST invoices and service reminders. A single-workshop system plans at about ₹2.6 to ₹3.9 lakh on the WavX estimator. One small workshop is usually better served by ready-made garage software.

What WavX builds

WavX builds garage management software as a custom web application used at the service desk and on the workshop floor, with an optional mobile app for mechanics or customers. It suits multi-brand service centres, body and paint shops, two-wheeler workshops, detailing studios and small chains. It is one of the custom software and business systems WavX offers.

A workshop's day turns on the job card. A car comes in, someone records the complaint and the odometer, a mechanic inspects it, the advisor prices parts and labour, the customer approves, parts are issued, work is done and checked, and an invoice goes out. Most of the cost of running a garage on paper or spreadsheets comes from the gaps between those steps: a part issued but never billed, an approval given on a phone call nobody recorded, a car promised for five o'clock with no one tracking it.

Custom software is worth considering when you have:

Several outlets that should share customers, vehicle history, parts and pricing.

Insurance or fleet work with its own approval and billing rules.

A customer-facing app or website that should show live job status or book services.

A process of your own , such as packages, extended-warranty work or doorstep pick-up, that ready-made products force into workarounds.

How the workshop type changes the software

The same modules weigh differently depending on the work. Scoping starts by placing your workshop in this table.

Workshop type

What dominates

What the software must get right

Two-wheeler service

High volume, short jobs, walk-ins

Fast check-in (registration number and phone only), a token queue, service packages

Multi-brand car service

Advisors juggling many open jobs

Estimates and approvals, promised times, parts issued against each job

Body and paint shop

Long jobs, insurance claims, photos

Damage photos at check-in, claim and surveyor tracking, the insurer and customer split on the bill

Detailing studio

Packages, memberships, repeat visits

Package balances, before-and-after photos, reminders by date

Fleet maintenance

Contract customers, many vehicles each

Per-fleet rates, approvals by the fleet manager, monthly consolidated invoices

Small chain

Several of the above at once

Shared vehicle history, central parts pricing, outlet-level reports

A body shop and a two-wheeler workshop can use the same underlying system, but the screens the staff see every day should be different. That difference is most of the case for building rather than buying.

GST and the invoice

A garage invoice usually mixes parts and labour, which can carry different tax treatment, so the software should let your CA set the tax per item rather than per invoice.

E-invoicing applies only to B2B invoices. As of October 2026, the e-invoice portal states that it is mandatory for businesses whose aggregate annual turnover exceeds ₹5 crore, from 1 August 2023. A workshop above that threshold with fleet or corporate customers needs those invoices registered and carrying an IRN and QR code; walk-in car owners are B2C and are not covered. The GST e-invoicing integration page explains how that connection works. This is a description of the software, not tax advice.

WhatsApp in the workflow

For most Indian workshops, WhatsApp is already the channel for photos, estimates and "your car is ready" messages, sent from a personal phone. Moving it onto the WhatsApp Business API means the messages come from the business number, are sent automatically at each stage of the job card, and are stored against the job. Meta has charged per message since 1 July 2025. As of October 2026 its pricing page lists marketing, authentication and utility templates as charged, with utility templates and ordinary replies free inside an open customer service window. Service reminders sent months after a visit are templates, so they are a running cost separate from the build.

What it costs to plan for

Planning ranges from the WavX software cost estimator , with small scale and standard design selected. A range is the subtotal minus 15% to plus 25%. They are not quotes.

Insurance workflows, fleet billing and a Tally link can each move the figure. Running costs are separate: hosting, WhatsApp message charges, payment gateway fees, and maintenance, which WavX plans at 15–25% of build cost per year . The garage software cost guide compares subscription and custom costs in more detail.

How the build runs

A day at the workshop. Follow three or four cars from gate to delivery, including one insurance job if you do them. The module list comes from what actually happens, not from a feature checklist.

Design for the floor. Screens that work on a phone with greasy hands: large buttons, photo capture, as little typing as possible.

First release. Job cards, inspections, estimates, parts and invoicing, used in the workshop while the next modules are built.

Data migration. Customer and vehicle lists, and opening parts stock, imported from your current sheets or software.

Parallel running and go-live. A week of both systems, then the switch.

Second release. Reminders, customer app, insurance and fleet modules, in the order that earns most.

When ready-made garage software is the better buy

Do not commission a custom build if:

You run one workshop with a few bays and mostly walk-in customers. Ready-made garage products cover job cards, parts and invoices for a monthly fee, and start this week.

Your real problem is that nobody records parts issues. That is a discipline problem first. Software makes it visible, but it will not fix it on its own.

You do not know your numbers yet. If you cannot say how many jobs a month you handle or what the parts margin is, run a ready-made product for six months. You will learn what you actually need, and any later custom build will be better scoped.

A custom system starts to pay off when outlets multiply, when insurance and fleet work make up a large share of revenue, or when the business wants a customer app that is its own rather than a vendor's.

What to have ready before asking for a quote

Number of outlets, bays, advisors and mechanics.

A sample job card, estimate and invoice, paper or digital.

Your parts list and how stock is counted today.

Whether you do insurance, fleet or doorstep work.

Which systems it must talk to: Tally, a website, WhatsApp, a payment gateway.

Frequently asked questions

How much does custom garage management software cost?

On the WavX software cost estimator, a staff-only system for one workshop plans at roughly ₹2,63,500 to ₹3,87,500, and a system with online payments, customer approvals and live job status at ₹6,63,000 to ₹9,75,000. These are planning ranges, not quotes; the price is fixed after scoping.

Should a small workshop build its own software?

Usually not. A single workshop with a few bays and walk-in customers is well served by a ready-made garage product or a billing app. Custom software pays off for multi-outlet chains, insurance-heavy body shops, fleet contracts, or workshops that need the system tied into their own website, app or accounts.

Does the software have to generate GST e-invoices?

Only for B2B invoices, and only if your aggregate annual turnover crosses the threshold. As of October 2026 the e-invoice portal states that threshold as ₹5 crore, applicable from 1 August 2023. Fleet and corporate customers are B2B; most walk-in car owners are not. Your CA should confirm how it applies to you.

Can customers approve repair estimates on WhatsApp?

Yes. The usual design sends the estimate with photos from the inspection as a link on WhatsApp, the customer approves or rejects each line, and the approval is stored against the job card with the time it was given.

Will it work with Tally?

It can. Invoices, receipts and parts purchases can be sent to Tally so the accounts are not keyed in twice. The scope of that link is agreed during scoping.

Related questions WavX has answered

Pos software custom build australia gst tax invoice?

A custom POS for an Australian business needs tax invoices showing GST the way your accountant requires, prices in AUD, and usually a link to your accounting software and card terminals. Integrated card terminals depend on what the terminal provider's API allows, so check that before design. WavX builds POS systems as custom code with the quote built in INR; its working day is 2:30 PM–11:30 PM AEST, giving afternoon overlap. Terminal and printer testing has to happen on your premises.

I head purchase at a 120-person auto-parts factory in Faridabad. Purchase requests come on paper, vendor quotes sit in email, and nobody knows which PO is pending approval. Management won't fund a full ERP this year. What kind of software should I ask for?

Ask for a standalone purchase and vendor management tool that can join an ERP later: digital purchase requests, vendor quotes side by side, PO approval by amount limits, goods receipt against the PO, a vendor record with rates and rejections, and a pending-approvals screen. An internal tool starts at ₹2,00,000 in WavX's published cost model, and the version with roles and reporting is about ₹2.6L–₹3.9L over 4–8 weeks, a fraction of the ERP line. The price can be negotiated; /tools/software-cost-estimator gives a figure to take to management. Source

I'm an architect running a 10-person studio in Doha. We track projects in spreadsheets, timesheets in another tool and invoices in accounting software, and nothing connects. Clients also want progress reports in Arabic and English. Should we buy practice management software or build something custom?

Buy first unless your process is unusual: packaged practice tools already combine project stages, timesheets, fees and invoicing,, and for ten people a subscription usually costs less. Custom makes sense when they cannot produce bilingual Arabic and English client reports or connect to your accounting software. If you build, an internal tool starts at ₹2,00,000 in WavX's published cost model, roughly $2,000–3,000, quoted in INR. A reporting layer on top of your current tools is the smaller first step, and the price is open to discussion. WavX works 7:30 AM–4:30 PM Qatar time. Source

We sell auto accessories on Shopify from Pune and pay for seven apps: bundles, COD verification, pincode checker, GST invoices, reviews, WhatsApp notifications and loyalty. The monthly app bill keeps climbing and the store is slow. Would one custom app replacing some of these make sense, and which ones?

Replacing four of the seven makes sense: the pincode checker, COD verification rules, GST invoices and bundles are simple logic specific to how you sell, and one custom app can run them with a single storefront script. Keep reviews and loyalty, which are mature products, and keep WhatsApp with its provider but trigger messages from the custom app. Compare the build plus hosting and maintenance against two or three years of cancelled subscriptions. WavX builds this as your own software, fully custom, with a pricing model that fits you; write to helpwavx@gmail.com. Source

Whatsapp approval workflow software?

A WhatsApp approval workflow sends the approver a message with the request details and reply buttons, and records the tap as an approval or rejection in the business system. It runs on the WhatsApp Business API, not the ordinary app, using pre-approved message templates. The system must confirm the approver's identity by their registered number, log every decision with a timestamp, and offer a web link for requests that need attachments or comments. Approvals above a set amount are better confirmed inside the system itself, with a one-time password, than by a chat tap alone. Source

Coaching institute management software custom price?

For a coaching institute, WavX's published cost model points to an internal tool, base ₹2L, and the worked example with roles and reporting is about ₹2.6L–₹3.9L over 4–8 weeks, covering batches, attendance, fee instalments and enquiry follow-up. A student app, online tests or recorded lectures move it towards a custom web application, ₹3.83L–₹5.63L before add-ons. A single-centre institute is often better served by a ready-made product; custom pays off with several centres. Tell WavX your budget and the scope is shaped to it; ask at helpwavx@gmail.com. Source

Production planning software custom build cost australia?

A custom production planning system maps to a custom web application in WavX's published cost model, starting at ₹4,50,000, roughly A$6,900–10,000 base, with roles, reporting and integrations priced as add-ons. That is an approximate conversion; the quote is built in INR. User roles, an accounting-package connection and a tablet view for the floor move it most, so a first version without the integration costs less. WavX treats the figure as open to discussion after a free consultation. It works 2:30 PM–11:30 PM Sydney time, an hour later in daylight saving. Source

Custom invoicing software vs zoho invoice which is better?

A ready-made tool such as Zoho Invoice is the better choice when your invoicing is standard: fixed items, normal taxes, one approval. Custom invoicing software earns its cost when the invoice is calculated from something the tool cannot model, such as usage pulled from your own system, milestone billing across projects, commission splits, or several legal entities with different numbering and tax rules. The practical test is how much is being fixed by hand in spreadsheets each month. If that work is small, stay on the ready-made tool. Source

WavX starting prices (base scope, before add-on features)

From the cost model behind the WavX calculators. A quote follows a scoping call; features, integrations and scale move these figures. Annual maintenance is typically 15–25% of the build cost.
