Small businesses run on notebooks, WhatsApp and memory. The apps that help are boring in the best way: bookings, stock, invoices, loyalty. A prototype is the quickest way to show a shop owner (or your future self) exactly what the tool would look like before committing to building it.
Each idea below is one screen you would actually open during a working day.
Slots, stylists and reminders.
A booking app for a hair salon: a week view of available slots per stylist, a customer booking flow with service and duration, a confirmation screen and a daily schedule view for staff.
Orders by table, ready when ready.
A café ordering app: a menu with categories and modifiers, a cart, table number selection, and a kitchen screen listing open orders by table with a "ready" button that moves them to done.
Know what to reorder before it runs out.
A stock tracker for a small shop: products with quantity, reorder level and supplier, a low-stock alert list, quick +/- adjustments, and a "reorder list" you can copy as a message.
Clients, line items, PDF-style preview.
A freelancer invoicing app: client list, create an invoice with line items and tax, a printable preview that looks like a real invoice, statuses (draft, sent, paid) and a monthly income summary.
Buy nine coffees, get the tenth free.
A digital loyalty card app for a coffee shop: customers see a stamp card that fills with each purchase, staff have a code-entry screen to add a stamp, and rewards are redeemed with a celebratory animation.
Who cleans where, and what to check.
A job scheduler for a small cleaning company: jobs by day with address, staff assigned and a checklist per property, a route order for the day and a job completion form with notes.
Quick tap sales and end-of-day totals.
A sales tracker for a market stall: big product tiles to tap when something sells, running total for the day, cash vs card toggle, and an end-of-day summary with best sellers.
Build a quote on site, send it before you leave.
A quote builder for a plumber: pick common jobs and parts from a list, adjust quantities, add labour hours, see the total with VAT, and generate a clean quote page with the customer's details.
Tables, covers and a waitlist.
A restaurant reservation app: a floor plan of tables drawn with CSS, bookings by time slot with party size, a waitlist with estimated wait, and a "seat" action that marks a table busy.
Every dog's notes, history and next visit.
A client card app for a dog groomer: pet profiles with breed, temperament notes and preferred cut, visit history with prices, upcoming appointments and a reminder list to send.
Who works when, swaps included.
A shift rota app for a small café team: a weekly grid of staff and shifts, drag-free swap requests, an availability screen per person and a total-hours count per staff member.
A tablet by the door: how was it today?
A feedback kiosk app for a tablet by the exit: a big smiley scale, optional one-line comment, thank-you screen, and a hidden manager dashboard showing today's scores and comments.
