Zimam is a comprehensive app for managing your electronics retail store on installment plans. It brings together your customers, contracts, installments, inventory, and portfolio in one place, without needing an internet connection and without any hassle.

Customer and Contract Management: Register your customers' data (name, mobile number, ID number) and create installment sales contracts in just a few clicks. Choose between automatically calculating the installment based on the total price and the number of months, or entering the installment amount directly and letting the app calculate the number of months automatically.

Precise Installment Scheduling: A complete monthly installment schedule for each contract, with recorded payments (cash or bank transfer), the ability to postpone or defer installments as needed, and automatic closure of fully paid contracts.

Inventory Management: Record available devices for sale at the selling price and cost price, and link them directly to sales contracts. The app automatically displays the remaining quantity, best-selling devices, and most profitable ones.

Portfolio and Capital: Track your actual capital in real time: cash flow, current inventory value, and amounts owed by customers – in addition to the net profit and loss from each sale.

Printable Reports
Print or share via WhatsApp: any customer's account statement, official sales contract, payment receipts, a general report for all customers, and an inventory and profit report.

Hijri and Gregorian Calendar
Every date in the app (contracts, installments, receipts) is displayed in both calendars.

Automatic Reminders
Proactive notifications for due installments and late payment alerts, with the option to send reminders directly to the customer via WhatsApp.

Privacy and Security
Your data is stored only on your device, without any external server or cloud account. You can create a full backup, export it at any time, and restore it on any device.

SADAD is designed specifically for small and medium-sized businesses that sell on installment plans and need a simple and practical tool to keep track of exactly where their money is.
