# What is Pleo

Pleo is a **spend management platform** that sits between company spending and downstream **ERP** and **Accounting Systems (AS)**.

It captures, validates, and prepares expense data so that only **complete, compliant, and accounting-ready records** reach your general ledger.

## Who Pleo Is For

Pleo is used by employees who spend company money (**spenders**) and by finance teams who review, control, and export that spend.

* **Employees (spenders)**\
  Submit expenses, attach receipts, and provide required information at the point of spend.
* **Finance teams**\
  Review spend, enforce company policy, and ensure expense data is complete before export to accounting systems.
* **Developers and architects**\
  Integrate clean, structured expense data into ERP and Accounting Systems via well-defined APIs.

## Where Pleo Fits

Pleo operates **upstream of accounting systems**.

* Employees spend money using cards or submit expenses.
* Pleo helps finance teams review, validate, and approve expenses through workflows, controls, and supporting information.
* Only approved data is exported to ERP or Accounting Systems.

<Note>
  Pleo does **not** replace your general ledger, reporting, or tax engines. It prepares expense data *before* bookkeeping.
</Note>

## Why Integrate with Pleo?

* Spend validation happens upstream.
* Accounting systems receive immutable, ready-to-book data.
* Clear system boundaries reduce integration complexity.

## What Comes Next?

* **Understand the platform’s role in your workflow**
