How to make an app for an electronics shop

An electronics shop sells fewer, bigger items, and each one has a serial number, a delivery date, an installation to arrange and a warranty that runs for years. When a customer calls about a fridge bought eighteen months ago, an app finds the bill, the serial number and the warranty end date in seconds.

Who uses the app

The owner, the counter and the delivery staff. If only the counter phone uses it, data can stay on that phone. If the delivery person marks installations on his phone, or customers browse a catalogue, connect your own Supabase database so everyone sees the same records.

The screens an electronics shop app needs

• Stock: Each model by type and size with its serial numbers, cost and selling price, and how many are in the godown
• New sale: Pick the model and serial number, customer name, phone and address, price, payment mode and any exchange item
• Deliveries: Today's and tomorrow's deliveries by area, with installation needed or done
• Service complaints: Complaints from customers, the product and serial number, the maker's complaint number and status
• Warranty lookup: Search by phone, name or serial number to see the bill date and warranty end date
• Catalogue: For customers: products by type and size with photos and an 'ask today's price' button on WhatsApp

Features worth asking for

• Scan the serial number barcode on the box with the phone camera (in the installed app)
• Warranty end date worked out from the bill date and the warranty period you enter
• Delivery list grouped by area with a call button and a Google Maps link for each address
• A WhatsApp message to the customer with the delivery day and the installation contact
• Exchange items recorded with condition and value given
• Sale bills as PDFs to share on WhatsApp or print from the phone
• A phone reminder in March to call customers whose ACs were sold last summer

Where the data lives

If one counter phone runs the app, data can stay on it, but back it up: warranty lookups may be years later. If the delivery person or a second counter uses it, or customers browse the catalogue, connect your own Supabase database from the chat.

How to make it with AppCub, step by step

1. Decide what the app does. List the screens you need, for example: Stock, New sale, Deliveries, Service complaints, Warranty lookup.
2. Describe it to AppCub. Paste the request below, changed to your own business and details.
3. 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.
4. Try it on your phone. The app runs live next to the chat. Scan the QR code to install it, and ask for changes.
5. 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 electronics shop, and paste it into AppCub:

Tips for an electronics shop app

• Type in serial numbers at the time of sale, or scan them; a warranty lookup is only as good as that entry.
• Keep the maker's service centre numbers in the app so you can pass them on when a customer calls.
• Start with large appliances, where serial numbers and installation matter. Add small appliances later if you need them.
• Agree with your delivery staff on what 'installed' means before they start marking it.
• Try a week of real sales with the old register alongside, then move to the app fully.

What it costs

• Describing your app and seeing AppCub’s plan for it is free.
• A new app usually takes 60 to 110 credits. Start with the 2-day trial for ₹99 (150 credits, enough for one app and a few changes) or the one-time App Pack for ₹499. Starter is ₹1,599 a month for 700 credits.
• Google Play needs a paid plan (it includes the Play Store bundle and your app’s signing key) and your own Google Play developer account, a one-time US$25 fee to Google.
• Work that fails or is rolled back costs no credits.

Good to know

• AppCub doesn't connect to billing software, the maker's service systems or a separate barcode scanner, and it can't book installations with the maker. Complaints are noted in the app and raised with the maker by you.
• 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 tell me when a customer's warranty ends?

Yes. Enter the warranty period for each product type, and the app works out the end date from the bill date. Search by phone or serial number.

Can I scan serial numbers into the app?

Yes, in the installed Android app the phone camera can scan the barcode on the box. It doesn't work in the web preview.

Can the app plan the day's deliveries?

Yes. Ask for a delivery screen grouped by area, with each customer's address, a Google Maps link and a call button.

Can I track complaints I raise with the maker?

Yes. Save the customer, product, serial number, the maker's complaint number and the status, and see which complaints are still open.

Can customers pay for an appliance in the app?

Yes, through your own Razorpay account after you connect Razorpay and Supabase. Many shops still take payment at the counter or on delivery.

Can the app remind me about AC servicing before summer?

Yes. The installed app can show a reminder on your phone on a date you set, with a list of last year's AC buyers and a WhatsApp button for each.
