Important: Please be informed that the deposit received will be fully forwarded to the hotels to secure the room block. Final invoices will be issued by B Network Management SLU under the Special Regime for Travel Agencies, reflecting the total gross amount for accommodation services, including VAT. Due to this special tax regime, VAT is included in the total amount without separate itemization and is fully paid according to Spanish tax laws.

As an intermediary governed by this special regime, B Network Management SLU cannot re-invoice VAT from foreign territories such as Turkey. Therefore, invoices issued by B Network will show the total amount invoiced by the hotels (room + tax), without disclosing the VAT amount separately, and this VAT cannot be reclaimed by the client.
