# Receipt Types

According to your company's fiscal configuration and customer type, Sarah can issue different types of receipts, for example:

- **Invoice A**
- **Invoice B**
- **Invoice C**
- **Invoice X** (internal / non-fiscal, according to regulation)
- **Credit notes** and **debit notes**

## Emit validations

Sarah blocks invalid combinations before sending to AFIP:

- **Invoice A** → Registered VAT (RI) customers with CUIT only. Monotax and VAT-exempt customers **cannot receive** Invoice A.
- **Invoice B** → not allowed when the customer is RI (use Invoice A). Monotax and exempt customers **can receive** Invoice B.
- **Invoice C** → only **monotax** or **VAT-exempt** issuers can emit it. Registered VAT businesses do not issue C receipts.

These rules apply in POS, sales invoice generation, and advanced invoicing.

## Automatic receipt type selection

When you generate an invoice from POS or the sales module:

- The system takes into account:
  - The company's **fiscal condition**.
  - Customer type (Registered Taxpayer, Monotax, Final Consumer, etc.).
- According to those rules, it suggests the most appropriate **receipt type**.

You can manually adjust the type in special cases, as long as it's valid according to regulations.

## Internal receipts (X)

**Invoice X** are usually used for:

- Internal receipts.
- Preliminary sales where you don't want to generate a definitive fiscal receipt yet.

In your company's configuration you can define when to use this type of receipts and how to migrate later to final fiscal receipts.
