Complete installment software built in PHP and MySQL for shops that sell mobile phones, motorbikes and home appliances on monthly payments. The customer pays an advance at the counter, then a fixed amount every month. The app keeps the customer, the sale, every payment, the balance and who is late in one place, and it works on a phone at the counter.
Each customer carries a photo, ID card copies (front and back), mobile and address. A new sale starts with a tap on the item type (phone, bike, TV, washing machine and more), then the product. The price, advance and number of months fill in from your own rate card, and the payment schedule builds live: the advance today, then equal monthly amounts with the last month taking the rest. Add up to two guarantors, check the review and save. Phones keep their IMEI, bikes their engine, chassis and registration numbers, appliances a serial number, and the same item can never sit on two running sales.
Every payment goes to the oldest unpaid month first, so there is never an argument about which month is paid. A receipt prints straight to an 80 mm or 58 mm thermal printer as a customer copy and an office copy, or as an A4 statement. The Due List splits customers into Chase today, Late, Due today and Next 7 days. One tap opens WhatsApp with a ready reminder that already holds the customer name and the amount.
Mobile shops, bike dealers and appliance stores that sell on installment and still track it in a register, and PHP developers who want a finished MySQL installment project to adapt for a client.
