## What You Can Do
### 🔐 Account & Authentication
Get started without leaving the conversation. You can create a Kash account, find existing accounts linked to your email, and authenticate via a secure one-time password (OTP) sent to your inbox — all from within the chat.
```
"Create a Kash account for my restaurant"
"Log me in with my email"
"I received the OTP code: 847291"
```
### 🧾 Sales & Orders
Record sales in real time, attach them to tables or customers, apply payment methods, add comments, and handle delivery modes — all from a single sentence.
```
"Record a sale of 2 espressos and a croissant at table 5, paid by card"
"Show me today's sales"
"What orders are pending for delivery tonight?"
"Give me the detail of order #1042"
```
### 📦 Catalog Management
Add, update, or remove items, departments, and VAT rates on the fly. Adjust prices, link variations, set stock levels, toggle visibility — without opening the back office.
```
"Add a new item called 'Seasonal Tart' at €4.50 in the Pastries department"
"Update the price of the Margherita pizza to €12"
"Create a new department called 'Summer Menu'"
"Add a 10% VAT rate"
```
### 👥 Customer Management (CRM)
Maintain a full customer database. Add new customers, update contact details, manage addresses, company registration numbers, VAT numbers, blacklist status, and private notes.
```
"Add a new customer: John Smith, [email protected], +33612345678"
"Update the address for customer #204"
"Show me all my customers"
```
### 📊 Data & Reporting
Retrieve any data from your shop instantly — products, departments, VAT rates, users, cashboxes, payment methods, delivery zones, discounts, tables, relay points, and more.
```
"List all my products"
"What payment methods are configured?"
"Show me this week's orders"
"How many tables do I have?"
```
