How to make an app for a building contractor

A thekedar runs several sites at once, each with its own mistri and labourers, cement and steel deliveries, and an owner who pays stage by stage. An app keeps daily attendance, material received and used, which stage each site is at and what each owner has paid, so Saturday's wage day and the owner's questions both have answers.

Who uses the app

The contractor and the site munshi or supervisor. If supervisors mark attendance at different sites on their phones, connect your own Supabase database; a contractor with one site can keep the data on one phone.

The screens a building contractor app needs

Sites: Each site with the owner, address, built-up area, current stage and amount received against billed
Attendance: Mistris and labourers present each day per site, with half days and overtime
Wages: Weekly wages per worker from attendance and daily rate, with advances taken
Material: Cement bags, steel, sand, aggregate and bricks received and used per site, with the supplier
Stages: Foundation, plinth, slabs, brickwork, plaster, flooring and finishing, with dates and photos you attach
Estimates and bills: Estimate by area and rate, and stage bills to the owner as PDFs

Features worth asking for

Daily attendance per site with half days, and weekly wages less advances
Material received and used per site, with cement and steel balance
Stage-wise bills to the owner as PDFs, with what was finished
An estimate PDF from built-up area at labour-only or with-material rates
Supplier dues for cement, steel and sand
Site location as a pin on a map and a Google Maps link for each site
A WhatsApp button to send the owner a stage update and the next payment

Where the data lives

If only you use the app, the data stays on your phone. If munshis at different sites mark attendance and material on their own phones, connect your own Supabase database so you see every site together.

How to make it with AppCub, step by step

Decide what the app does. List the screens you need, for example: Sites, Attendance, Wages, Material, Stages.
Describe it to AppCub. Paste the request below, changed to your own business and details.
Check the plan. AppCub shows the screens and features it will build. Change them in the chat until they are right; seeing the plan is free.
Try it on your phone. The app runs live next to the chat. Scan the QR code to install it, and ask for changes.
Share it. Share it as a web link, an APK file, or publish it on Google Play from your own developer account.

Copy this request, change the details to match your building contractor, and paste it into AppCub:

Make an app for my building contractor business, Malviya Constructions in Indore. Screens: sites, attendance, wages, material, stages, and estimates and bills. Sites have the owner, address, built-up area and stage. Mark mistris and labourers present each day per site, with half days; wages weekly at ₹900 for mistri and ₹550 for labour, minus advances. Record cement bags, steel, sand and bricks received and used per site with suppliers and dues. Stages: foundation, plinth, slabs, brickwork, plaster, flooring, finishing, with photos. Make estimates and stage bills as PDFs. Brick red colours.

Tips for a building contractor app

Start with attendance and wages; that is what you settle every week and where mistakes cost most.
Write your own stage names and payment rule into the request, so bills match the agreement with the owner.
Record every cement and steel delivery the day it arrives, with the supplier's challan photo attached.
Attach stage photos before you ask the owner for the next payment.
Ask for Hindi labels if your munshis will mark attendance.

Good to know

AppCub doesn't design structures, check drawings or connect to biometric attendance devices. It records attendance, material, stages and money as your team enters them.
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 work out weekly wages from attendance?

Yes. Mark each worker present, absent or half day per site, give daily rates, and the app totals the week less any advance taken.

Can I track cement and steel at each site?

Yes. Record what arrives and what is used per site, and the app shows the balance and what you owe each supplier.

Can the app make stage bills for the house owner?

Yes. When a stage is done, the app makes a bill PDF with the stage and amount, which you send on WhatsApp.

Can munshis at different sites use the same app?

Yes, with your own Supabase database connected. Each munshi marks attendance for his site on his phone.

Can I keep photos of each stage?

Yes. Attach photos to a stage from the camera or gallery; with many sites, connect a Supabase database so photos are kept online.

Can the house owner see progress in the app?

Yes, with an owner screen and sign-in on your Supabase database. Many contractors simply send stage photos on WhatsApp instead.
