What is BetterPOS?

BetterPOS is a complete point-of-sale solution designed for Roblox games. It provides merchants with professional tools to manage orders, track inventory, and analyze sales performance.

Key Components

ServerScript: Handles all backend logic and data processing
LocalScript: Manages the client-side user interface
RemoteEvent: Enables secure communication between client and server

Current Limitations (Alpha)

Some UI elements may not render correctly on all devices
Color configuration may occasionally return nil errors
Mobile responsiveness needs improvement
Analytics data may not persist across server restarts

Installation Guide

⚠️ Note: These instructions are for the unreleased alpha version. Bugs may occur.

Step 1: Prepare Your Game

Open your game in Roblox Studio
Create a new Model or use existing structure
Make sure you have ServerScriptService in your game hierarchy

Step 2: Install ServerScript

In ServerScriptService, insert a new ServerScript
Copy the entire BetterPOS_ServerScript.lua content
Paste into the ServerScript
The script will auto-create required instances

Step 3: Install LocalScript

Go to StarterPlayer → StarterCharacterScripts (or StarterPlayerScripts)
Insert a new LocalScript
Copy the entire BetterPOS_LocalScript.lua content
Paste into the LocalScript

Step 4: Test

Click "Play" in Studio
Check the Output window for initialization messages
Look for the POS interface in your game
Report any errors encountered

                -- Expected output when everything works:
[BetterPOS] ✓ Server ready!
[Client] ✓ Client ready!
[Client] ✓ All colors initialized: YES
            

Configuration

BetterPOS uses a central CONFIG table in the ServerScript. You can customize:

Business Information

                BusinessName = "Ice Cafe"
Tagline = "Premium Coffee & Treats"
            

Colors (Theme)

                Theme = {
    Primary = Color3.fromRGB(50, 160, 255),
    Secondary = Color3.fromRGB(100, 100, 255),
    Background = Color3.fromRGB(28, 28, 30),
    -- ... more colors
}
            

Menu Items

                Categories = {
    {
        Name = "Hot Drinks",
        Icon = "☕",
        Items = {
            {Name="Espresso", Price=5, MaxQty=10}
        }
    }
}
            

Other Settings

TaxRate - Percentage tax (0.08 = 8%)
OrderNumberStart - First order ID
MaxOrderHistory - Orders to keep in memory
ReceiptEnabled - Show receipts on purchase

Troubleshooting

❌ "Unable to assign property BackgroundColor3. Color3 expected, got nil"

Cause: Config colors aren't loading properly

Fix: Make sure the ServerScript runs before LocalScript. Check that BetterPOS_Config is properly created in ReplicatedStorage.

Status: Fixed in latest version

❌ "RemoteEvent not found"

Cause: ServerScript hasn't initialized yet

Fix: Wait a few seconds for the server to fully load, then rejoin the game

Status: Investigating

❌ UI doesn't appear on screen

Cause: LocalScript not in correct location or GUI creation failed

Fix: Verify LocalScript is in StarterPlayer → StarterPlayerScripts. Check Output for errors.

Status: Fixed

❌ Orders not being processed

Cause: Server not receiving cart data

Fix: Make sure RemoteEvent is properly connected. Check script console for errors.

Status: Under investigation

⚠️ Performance Issues / Lag

Cause: Too many UI updates or orders in history

Fix: Lower MaxOrderHistory to 50 instead of 100. Close unnecessary windows.

Status: Optimization in progress

Frequently Asked Questions

Q: Can I use this in my game right now?

A: You can, but expect bugs and incomplete features. It's best suited for testing and feedback at this stage.
