How to Install qs-inventory on a QBCore FiveM Server

Setting up a custom inventory system is one of the first things most QBCore server admins tackle — and qs-inventory (also called Quasar Inventory) is among the most popular choices in the FiveM roleplay community. It replaces the default ox_inventory or lj-inventory with a polished, feature-rich UI and deep QBCore integration. But the installation process has enough moving parts that skipping a step usually breaks something.

Here's a clear walkthrough of how the installation works, what variables affect your outcome, and where things tend to go wrong.

What Is qs-inventory and Why Does It Matter for QBCore?

qs-inventory is a premium inventory resource developed by Quasar Store, designed specifically for QBCore-based FiveM servers. It handles item management, stash systems, drop systems, shops, and weapon components — all through a custom UI that integrates directly into QBCore's item and player data framework.

Because QBCore uses a shared item registry and player metadata structure, your inventory resource needs to be tightly coupled with the framework. A mismatch between versions — even minor ones — can cause items to not load, weight systems to break, or the entire inventory to fail on player spawn.

Prerequisites Before You Install

Before touching any files, confirm you have the following in place:

• ✅ A working QBCore framework installation (up to date)
• ✅ oxmysql or a compatible async MySQL resource running
• ✅ Server artifact version meeting the minimum required by the qs-inventory release you're using
• ✅ Access to your server's resource folder via FTP, SFTP, or direct file access
• ✅ A licensed copy of qs-inventory from Quasar Store (it uses asset escrow via CFX)

The escrow system is worth noting: qs-inventory is encrypted through Cfx.re's asset escrow, which means it runs tied to your server's license key. This affects how you download and deploy the files.

Step-by-Step Installation Process

1. Purchase and Download from Quasar Store

After purchasing, navigate to your Quasar Store account and download the resource. The download will typically be a .zip containing the encrypted resource files alongside any open-source config files.

2. Extract and Place the Resource

Extract the folder and place it inside your server's resources directory. A common path looks like:

/resources/[inventory]/qs-inventory/ 

Organizing resources into subfolders (like [inventory] or [qb]) is a convention, not a requirement — but it keeps things manageable.

3. Import the SQL File

qs-inventory requires its own database tables. Inside the resource folder, locate the .sql file and import it into your server's database using a tool like HeidiSQL, phpMyAdmin, or via command line.

This step creates tables for stashes, drops, and item metadata. Skipping it means the inventory will partially load but fail when accessing stashes or persistent storage.

4. Update Your server.cfg

Add the resource to your server.cfgafter QBCore and oxmysql start, but before any resources that depend on inventory functions:

ensure oxmysql ensure qb-core ensure qs-inventory 

Load order matters significantly here. Resources that register items or interact with inventory on startup need qs-inventory already running.

5. Configure the Config File

qs-inventory ships with an open config.lua where you set:

• Weight limits per player, vehicle, and stash type
• Item slot counts
• Hotbar settings
• Decay and durability options (if using those modules)
• Shop and crafting integrations

This is where your server's identity starts to shape the install. A hardcore RP server will configure this very differently from a casual or action-focused server.

6. Replace or Redirect Dependent Resources 🔧

This is where many installs run into friction. Resources like qb-shops, qb-weaponshop, ps-inventory references, or any script that calls inventory functions directly may need their inventory-related code updated to point to qs-inventory's exports.

Quasar provides bridge files and documentation for common QBCore resources, but third-party scripts — especially older ones — may need manual edits to replace inventory function calls.

Variables That Affect Your Installation Experience

Common Points of Failure

Inventory opens but items don't load — usually a SQL import issue or a mismatch between item names in your QBCore shared items and what qs-inventory expects.

Resource fails to start — most often a load order problem in server.cfg, or the server license key not matching the escrow-linked download.

Stashes not saving — missing database tables or oxmysql not running before qs-inventory starts.

UI appears broken — sometimes a cache issue on the client side; clearing the FiveM cache folder typically resolves it.

How Different Server Setups Lead to Different Outcomes

A fresh QBCore server built around qs-inventory from the start is the smoothest path — you configure everything around it and avoid legacy conflicts.

A migrating server replacing an existing inventory system faces more complexity: database migration, dependent script updates, and potential item registry conflicts all add layers that a fresh install doesn't have.

A heavily modded server with dozens of custom scripts will spend the most time on step six — auditing and updating dependent resources — since every script that touches inventory is a potential point of breakage.

The actual installation of qs-inventory itself is straightforward. What varies dramatically is the surrounding ecosystem of your specific server build, which scripts you're running, and how current your QBCore version is. Those factors determine whether this is a one-hour job or a multi-session debugging process.
