# Inventory and Purchase Orders Home

Core Product

# **Inventory & Purchasing**

ServiceTitan provides two main features to help you manage inventory and purchasing across your business.

[**Jump to key workflows**](/docs/inventory-and-purchase-orders#key-workflows)

## **Key workflows**

### **Purchasing Module**

Your central hub for procurement.

The [Purchasing module](/v1/docs/purchasing-module) is your central hub for procurement. It allows you to:

Create and send purchase orders (POs) to vendors

Get notified when items are consumed

Send replenishment orders to restock items

Track receipts, returns, and expenses

### **Inventory Module**

Builds on the Purchasing module with deeper Inventory Management tools.

The [Inventory module](/v1/docs/inventory-module) builds on the Purchasing module and provides deeper inventory management tools. It allows you to:

Monitor inventory levels in [trucks and warehouses](/v1/docs/inventory-locations-overview)

[Transfer items between locations](/v1/docs/inventory-item-transfer-workflow)

Set minimum stock levels for automated replenishment

Receive alerts when stock is low

Manage [serialized inventory](/v1/docs/serialized-inventory-home) to track individual items

Perform regular [inventory counts](/v1/docs/inventory-counts) to ensure accuracy

Use [units of measure](/v1/docs/units-of-measure) to define how items are tracked and used

**Note:**

Effective use of the Inventory module depends on a good foundation using the [Purchasing module](/v1/docs/purchasing-module). After you are comfortable using Purchasing, review the steps to [Set up Inventory](/v1/docs/inventory-module#steps-to-set-up-and-use-the-inventory-module) and select an [Inventory implementation path](/v1/docs/inventory-implementation-path).

If you haven't enabled the Inventory feature, the main menu and settings menu display an option for Purchasing. If the feature is enabled, it displays as Inventory.

### **Additional Inventory features**

Automate purchasing and manage inventory on mobile.

Use Inventory Requisition to automate purchasing and optimize stock usage, keeping your stock levels efficient.

[Inventory requisition and invoice closeout](/v1/docs/inventory-requisition-and-invoice-closeout)

Use the Inventory Mobile app to track and manage today's purchase orders (POs), transfers, and inventory counts both completed and in progress.

## **Troubleshooting & FAQ**

Quick solutions to common issues and answers to frequently asked questions.

**Frequently Asked Questions**

****Can I use inventory if I don't have an accounting software?****

Yes. You can still use inventory even if you don't export to or integrate with an accounting software. Inventory functions independently and doesn't require an accounting system connection to operate.

****Do I need to create a job to track inventory when selling materials directly to customers?****

If you're selling *materials*, you can track inventory without creating a job. But if you're selling *equipment*, you must create a job to record the sale and update inventory.

Tracking of parts, materials, and equipment across warehouse locations and technician trucks.

**What it does:** Reduces material costs and job delays by giving managers real-time visibility into stock levels and enabling reorder automation.

**Also called:** Parts management, Stock tracking
