What are you going to learn here? How to sell products to customers who pass by your store or counter.
🎯 What is the Sales module?
This module is used to sell products to customers who come to your physical store.
Examples of use:
- A client comes in and wants 5kg of chlorine
- A community stops by to pick up material for their pool
- An individual purchases a pH meter
NOT for:
- ❌ Bill maintenance (that's Billing)
- ❌ Buy from suppliers (that's Purchasing)
- ❌ Online sales (this is only a physical store)
🏗️ Key concepts
POS vs Billing
| Concept | When to use | Example |
|---|---|---|
| POS (Quick Sale) | Customer passes by store and takes product | "I want 2kg of chlorine" |
| Billing | Charge periodic services | "Monthly maintenance bill" |
