Start from the work, not the screens
Before thinking about buttons, write down what the business does every day: who its customers are, what it sells, how people book or order, how it gets paid, what stock it keeps and who works there. A good business app follows that work; it doesn't make the owner change it.
What most business apps need
A list of customers with each person's history. Sales, invoices and receipts. Bookings or orders, with reminders that go out by themselves. Stock, staff and the day's money.
Some businesses need more: rentals with deposits and returns, a courier's parcels, appointments with several staff. Say what's special about the business, and the app is shaped around it.
An app on the phone, without the app store
An app built with Lynk works in the browser on any phone or computer, and installs on the home screen like an app, so the owner and the staff open it with one tap. There's nothing to download from a store and no waiting for approval, and every change reaches everyone at once.
Build it with Lynk AI
Describe the business in your own words, for example "an app to run a pharmacy: customers, sales and stock", or pick one of the ready-made apps. Lynk AI builds it around what the business does while it opens.
Then ask for changes the same way: add a detail to each customer, rename a step, change who sees what. The owner can run it by talking, too: Lynk AI records a sale, books a client or sends an invoice when asked.
Test it with real work before you hand it over
Enter a few real customers, make a sale, book an appointment, and check that the receipt and the reminder text arrive. Add the staff, each with only what they need to see. Then hand it to the owner and show them the three things they'll do most.
