How to make an app for a wholesale business

A wholesaler's day is rates, orders and dues: shops call for today's rate, send an order on WhatsApp, and pay part now and the rest later. An app keeps one rate list you update in the morning, lets regular shops order from it, tells the godown what to load and shows each party's balance.

Updated 2026-11-09

Who uses the app

The owner, the office and the godown staff, and optionally regular shops that order from the rate list. For shops to see your rates and the godown to see orders on their own phones, connect your own Supabase database, with sign-in so each shop sees only its own orders and dues.

The screens a wholesale business app needs

Rate list: Every item with carton rate, loose rate and pack size, changed by the owner each morning
Shop order: For shops: pick items and cartons from the rate list and send the order
Orders to load: Today's confirmed orders for the godown, with items, cartons and the vehicle
Godown stock: Cartons in hand for each item, goods received and a low-stock list
Party ledger: Each shop's bills, payments, balance and how many days the oldest bill is overdue
Bills: A bill for each order as a PDF to share on WhatsApp or print

Features worth asking for

Different rates by quantity, for example one rate per carton and another above 10 cartons
A rate list PDF you can send to your WhatsApp list every morning
Credit days per party, with a list of bills past their due date
A WhatsApp payment reminder with the party's balance filled in
Orders marked loaded and delivered, so the office knows what has gone out
Stock reduced when an order is loaded and increased when goods come in
Payments in the app through your own Razorpay, or a UPI QR, if shops want to pay online

Where the data lives

With the godown, the office and shops on different phones, connect your own Supabase database and turn on sign-in, so each shop sees only its own bills. Add Razorpay if shops should pay inside the app; the money goes to your account.

How to make it with AppCub, step by step

Decide what the app does. List the screens you need, for example: Rate list, Shop order, Orders to load, Godown stock, Party ledger.
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 wholesale business, and paste it into AppCub:

Make an app for my wholesale business, Patel Traders in Rajkot. We sell plastic and household goods to shops by the carton. Screens: rate list with carton and loose rates, shop order (shops pick items and cartons from the rate list), orders to load for the godown, godown stock, party ledger with bills, payments, balance and credit days, and bills as PDF. Rates above 10 cartons are lower. Make a rate list PDF to send every morning. Show overdue bills and a WhatsApp payment reminder. Shops sign in and see only their own orders. Navy and yellow colours.

Tips for a wholesale business app

Start with the rate list and the party ledger, the two things you check most often; add shop ordering once your regulars are used to the app.
Write your credit rule exactly, such as 15 days from the bill date, so the overdue list matches what you tell parties.
Enter opening balances for every party on one fixed date before you start.
Give each item the same name your godown staff use, or the loading list will confuse them.
Use a test shop for a week before inviting real parties.

Good to know

AppCub doesn't connect to Tally, your billing software or a weighing scale, and it doesn't file GST returns. Reminders go out when someone taps the WhatsApp button, not automatically.
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 shops place orders from my rate list in the app?

Yes. With your own Supabase database and sign-in, a shop opens the rate list, picks items and cartons, and the order reaches your office.

Can the app give different rates for bigger orders?

Yes. Tell AppCub your slabs, such as a lower rate above 10 cartons, and the order total uses the right rate.

Can I see which parties are overdue?

Yes. The party ledger shows each shop's balance and how many days the oldest unpaid bill has been pending, past the credit days you set.

Can the app send my rate list every morning?

It makes the rate list as a PDF; you tap share and send it to your WhatsApp list. It doesn't send it by itself.

Will the app sync with Tally?

No. AppCub doesn't connect to Tally or other accounting software. You can share bills as PDFs and enter them in your books.

Can my godown staff see what to load?

Yes. Give them a sign-in that shows only orders to load and godown stock, without rates or party balances.
