Basic System Concepts

Invoices

An invoice is an official document that proves a sale or purchase transaction. The system supports several types:

• Sales Invoice: When selling to a customer
• Purchase Invoice: When buying from a supplier
• Quotation: An offer to the customer before approval
• Return: Returning goods (sales or purchases)

Journal Entries

Every financial transaction in the system automatically creates a journal entry that includes:

• Debit: The account that increases (assets and expenses)
• Credit: The account that decreases (liabilities and revenues)

Chart of Accounts

• Assets: What the company owns (cash, inventory, equipment)
• Liabilities: What the company owes others (debts, suppliers)
• Equity: Capital and retained earnings
• Revenue: Company income from sales
• Expenses: Operating costs

Inventory

Tracking products and goods in warehouses:

• Available Quantity: Actual quantity in the warehouse
• Reorder Point: The quantity at which you need to reorder
• Inventory Cost: Average unit cost
