How to make an app for a plumber

A plumber's day is small jobs across town and one or two bigger bathroom jobs running for a week. An app keeps the calls you have promised, the fittings you bought for each job, the quote you gave and the money still due, so nothing is left on a scrap of paper in the van.

Who uses the app

Usually just you, on your own phone, so the data can stay on it. If a helper or a second plumber takes jobs from the same list on their phone, connect your own Supabase database so you both see the same jobs.

The screens a plumber app needs

Today: The day's jobs in order with the customer, locality, the problem and a Google Maps button; a map with pins for each address
New job: Customer name and phone, address, the problem, a photo you attach, and the time you promised
Quotes: Bathroom or kitchen plumbing quotes with points, pipe runs, fittings and labour, made into a PDF to send
Fittings: Fittings and pipe bought for each job, what you paid the dealer and what you charge the customer
Payments: Paid, part paid and due for every job, with a reminder button
Customers: Past jobs at each address, so a repeat call starts with what was fitted last time

Features worth asking for

A quote PDF for bathroom work listing points, fittings and labour, with your name and number on top
Fittings bought from the dealer recorded per job, so your margin on each job is clear
A map with pins for the day's addresses, opening Google Maps for directions
A WhatsApp button to tell the customer you are on the way, with your name and the time
A phone reminder the evening before each promised visit (installed app; it can arrive a few minutes late)
Helper days and wages per job, totalled each week
A due list with a polite WhatsApp payment reminder

Where the data lives

If only you use the app, the data stays on your phone and works without internet at a site. If a helper or partner uses it on another phone, connect your own Supabase database; add Razorpay only if you want customers to pay by link, with the money going to you.

Tips for a plumber app

Start with today, new job and payments; add quotes and fittings once you are entering every job.
Give AppCub your usual rates for a point, a tap change and a geyser fitting, so a quote fills itself in faster.
Note the fittings you put in at each address; when the same customer calls next year you will know the make and size.
Attach a photo of the leak or the old fitting to the job; it helps when the customer asks what was changed.
Ask for Hindi labels if you are more at ease reading them.

Good to know

AppCub doesn't track you live on a map or give turn-by-turn directions, and it doesn't message customers by itself. Directions open in Google Maps and messages go out when you tap the WhatsApp button.
AppCub builds Android apps. You can also share the app as a web link that opens on any phone; for the iPhone App Store, AppCub’s team can do it for you.

Questions

Can the app make a quote for a full bathroom?

Yes. Ask for a quote screen with points, pipe runs, fittings and labour; it adds them up and makes a PDF you send on WhatsApp.

Can I see my day's jobs on a map?

Yes. The app can show a map with a pin for each job's address. Tapping a pin opens Google Maps for directions; there is no live tracking.

Can the app tell me what I earned on each job?

Yes, if you record what you paid the dealer for fittings and the helper's wages. The app shows the bill minus those costs.

Will the app remind me of visits I promised?

In the installed Android app, yes: a reminder on your phone at the time you set, which may come a few minutes late. It doesn't message the customer.

Does a plumbing app work without internet?

Yes, when the data is kept on your phone, which is the default. You can enter a job in a basement or a site with no signal.

Can my helper take jobs from the same app?

Yes, once you connect your own Supabase database. Then each of you sees the same job list on your own phone.
