System Overview
Core Concepts
Store & Device Model
A Store is the top-level account (e.g. "Ahmed's Supermarket"). Each physical device (phone, laptop) is a Device that belongs to a store. All devices share the same customers, suppliers, and transactions via cloud sync.
Customers vs Suppliers
- Customer — a person or business that buys from you on credit. A positive balance means they owe you money. A negative balance means you over-collected (rare).
- Supplier — a company you buy stock from on credit. A positive balance means you owe them money. A negative balance means you over-paid.
Sync Queue
Every change made on a device (create/update/delete) is written to a local sync queue. When the device has network access, the queue is flushed to the server (push), and new changes from other devices are downloaded (pull). This ensures the app is always usable, even without internet.
