How is VAT handled?

All amounts are stored VAT-exclusive, with VAT amount stored separately. The system supports both VAT-inclusive and VAT-exclusive input, and display logic applies VAT based on user preference.

Can I use services from the catalog?

Yes! You can select services directly from the service catalog in billables. Service details (name, price, unit label) are automatically populated, and service snapshots are saved for historical accuracy.
