# What is Rex and How Does It Work?

## How Outmin's reconciliation assistant requests missing documents and clarifications

**Rex (our reconciliation assistant)** is how Outmin asks clients for missing documents or clarifications, usually when something shows up in the bank feed without a matching invoice or needs to be categorised.

- Clients/firms get a notification via the Outmin app or dashboard
- They just need to upload the missing document or add a quick note 
- It's simple and essential to keeping their books accurate

### **What firms need to do:**

- Make sure clients are using the app and responding to Rex
- If Rex messages are piling up, give clients a nudge - it slows things down and can affect the accuracy of VAT returns and reports
