# Calculating Shipping Costs

Sarah's system can automatically calculate shipping costs using integration with Correo Argentino, based on package characteristics and destination.

## How It Works

### Automatic Process

1. **Enter package information**: Weight, dimensions, declared value
2. **Enter destination**: Delivery address
3. **System queries Correo Argentino**: Gets rates in real time
4. **You receive cost**: Calculated cost and available options

### Factors Affecting Cost

Shipping cost depends on:

- **Weight**: Package weight in grams
- **Dimensions**: Height, length, and width in centimeters
- **Declared value**: Package content value
- **Delivery type**: Home or branch
- **Destination**: Province and postal code
- **Product type**: Postal letter (CP) or other types

## From POS

### Add Shipping to a Sale

1. **Create or open a sale** in POS
2. **Add products** to cart
3. **Enable shipping**: Mark "Requires shipping" or similar
4. **Complete shipping information**:
   - Destination address
   - Package weight
   - Dimensions (optional, but recommended)
   - Declared value
5. **Calculate shipping**: System queries Correo Argentino
6. **Cost is shown**: Cost is added to sale

### Required Information

**Destination Address:**
- Street and number
- Floor and apartment (optional)
- City
- Province (province code)
- Postal code

**Package Characteristics:**
- Weight (in grams)
- Height (in centimeters)
- Length (in centimeters)
- Width (in centimeters)
- Declared value (in pesos)

**Delivery Type:**
- Home (D)
- Branch (S) - requires agency code

## From Online Store

### Automatic Calculation in Checkout

In the online store, calculation is automatic:

1. **Customer adds products** to cart
2. **Chooses home delivery**
3. **Enters destination address**
4. **System calculates automatically**:
   - Sums product weights
   - Uses estimated dimensions (if configured)
   - Calculates declared value (cart total)
   - Queries Correo Argentino
5. **Shows cost to customer**: Customer sees cost before paying

### Product Configuration

For accurate calculations, configure in your products:

- **Weight**: Individual weight of each product
- **Dimensions**: Height, length, and width (optional but recommended)

System automatically sums:
- **Total weight**: Sum of weights of all products
- **Dimensions**: Calculates total dimensions (or uses estimates)

## Delivery Types

### Home (D)

Direct delivery to customer's address.

**Requirements:**
- Complete and valid address
- Correct postal code
- Correct province

**Advantages:**
- Convenience for customer
- Customer doesn't need to travel

**Disadvantages:**
- May be more expensive
- Requires someone to be at address

### Branch (S)

Customer picks up at a Correo Argentino branch.

**Requirements:**
- Correo Argentino agency code
- Customer must pick up personally

**Advantages:**
- Generally more economical
- Customer can pick up when they want

**Disadvantages:**
- Customer must travel
- Requires agency code

### Get Agencies

You can get the list of available agencies:

1. **From POS or configuration**
2. **Select destination province**
3. **System queries Correo Argentino**
4. **Shows agency list** with codes
5. **Select agency** for shipping

## Calculation Example

### Scenario

- **Weight**: 500 grams
- **Dimensions**: 20cm x 15cm x 10cm
- **Declared value**: $5,000
- **Delivery type**: Home
- **Destination**: CABA, postal code 1425

### Process

1. System prepares request with this data
2. Queries Correo Argentino API
3. Receives response with cost
4. Shows: **$1,200** (example)

### Result

Cost is added to sale and customer pays it along with products.

## Common Errors

### Error: "Could not calculate cost"

**Possible causes:**
- Integration not configured
- Invalid credentials
- Incomplete information
- Temporary Correo Argentino error

**Solution:**
1. Verify integration is configured and enabled
2. Review that all fields are complete
3. Try again after a few minutes

### Error: "Invalid address"

**Possible causes:**
- Incorrect postal code
- Incorrect province
- Malformed address

**Solution:**
1. Verify postal code
2. Confirm province is correct
3. Review address format

### Cost Too High or Too Low

**Possible causes:**
- Incorrect weight
- Incorrect dimensions
- Incorrect declared value

**Solution:**
1. Verify package weight
2. Review dimensions
3. Confirm declared value

## Best Practices

### Accuracy in Measurements

- **Weigh products**: Don't estimate, actually weigh
- **Measure dimensions**: Use real dimensions, not estimates
- **Update regularly**: If you change products, update measurements

### Declared Value

- **Use real value**: Declare real content value
- **Consider insurance**: Declared value affects insurance cost
- **Don't underestimate**: To protect yourself in case of loss

### Product Configuration

- **Configure weight**: Add weight to all products
- **Configure dimensions**: Add dimensions when possible
- **Use averages**: If products vary, use reasonable averages
