IČO Auto-fill Functionality Test

Implementation Summary

The IČO auto-search functionality has been successfully implemented in the customer creation modal. Here's what was added:

Features

1. Automatic Search: When a user enters an 8-digit IČO, the system automatically searches the Czech company registry (ARES)
2. Auto-fill: Found company information is automatically populated in the form fields:
   • Company name (Název firmy)
   • DIČ (if available)
   • Address (Adresa)
   • City (Město)
   • ZIP Code (PSČ)
   • Country (Stát)
3. Visual Feedback: Loading spinner appears during search
4. Error Handling: User-friendly notifications when company is not found

How to Test

1. Navigate to the Fakturace page
2. Click Nová faktura
3. Click Přidat odběratele button
4. Enter a valid 8-digit Czech IČO (e.g., 24330621)
5. The system will automatically search and fill in the company details

Test Examples

Valid Czech IČO numbers for testing:

• 24330621 - Tomáš Dvořák (Individual)
• 25596641 - Microsoft s.r.o.
• 27791331 - Google Czech Republic s.r.o.
• 62739913 - Seznam.cz, a.s.

Technical Implementation

• API: Uses ARES (Administrativní registr ekonomických subjektů) - Czech company registry
• Endpoint: https://ares.gov.cz/ekonomicke-subjekty-v-be/rest/ekonomicke-subjekty/{ico}
• Validation: Only searches when exactly 8 digits are entered
• Input Sanitization: Automatically removes non-digit characters and limits to 8 digits

User Experience

• The search triggers automatically when the 8th digit is entered
• Loading spinner provides visual feedback during the search
• Success message confirms when data is found and filled
• Warning message appears if no data is found, allowing manual entry
• All auto-filled fields can still be manually edited by the user

Error Handling

• Network errors are handled gracefully
• Invalid IČO numbers show appropriate warnings
• CORS issues are resolved by using the public ARES API
• Form validation ensures required fields are still manually validated

The implementation provides a seamless user experience for adding new customers by reducing manual data entry and ensuring accuracy through official registry data.
