Personal POS – Sales & Stock is a point-of-sale application designed for iPhone and iPad that manages sales, inventory, purchases, customers, credit, cashiers, cash closing, tickets, and reports. The app operates offline-first and keeps data private on the device. It is intended for small retail businesses that need a complete operational tool without requiring additional modules or add-ons. The application supports selling by searching product name or code, scanning barcodes, and applying discounts, variants, and wholesale prices. Inventory tracking records every unit movement as an auditable event, including purchases, sales, returns, and adjustments. Stock alerts notify users when items are low or out of stock. Supplier purchases can be registered with drafts, partial receiving, discounts, and cost tracking, with received goods flowing directly into inventory. The app also handles multiple payment methods, credit sales with real balances, cashier control, and a daily cash closing that compares expected amounts against counted cash by payment method. Customer management includes full profiles with credit limits, open balances, available credit, sales history, and automatic customer codes. Price tiers can be set per customer, and wholesale prices apply from a minimum quantity. Variants such as size, color, shoe number, or combinations are tracked under one product code. Sales can include line-level or ticket-level discounts, partial payments, due dates, and credit aging reports that list oldest receivables first. Reports are available in CSV and PDF formats for sales, transactions, average ticket, estimated profit, inventory value, and stock alerts, filterable by day, week, month, or custom range. Typical workflows follow the real flow of a store: stock is received from suppliers, products are sold, money is collected, and the day is closed. The app provides live sales views, sale details with full audit trails, cancellations, duplicates, customer returns, and PDF receipts. Purchase documents, cost change audit trails, and supplier returns are also supported. The app requires an iPhone or iPad and functions without an internet connection for core operations.
