The money adds up. Tax time too.

1. Under Invoices → ⋯ → Invoice settings → Surcharges, set a weekend and a public holiday surcharge, each as an amount or percentage, and choose your federal state.
2. When you bill walks, every walk on a weekend or public holiday gets its own dated surcharge line.

There is at most one surcharge per walk; on a public holiday the holiday surcharge applies. Subscription invoices stay flat-rate. Holidays observed only in individual municipalities are not included. Public holidays are currently available for Germany.

DATEV is the accounting software most German tax advisors use. You find the export under Invoices → ⋯ → DATEV export when your iPhone is set to the Germany region. Choose a month, quarter or year and you get CSV files in the DATEV booking batch format: one with revenue from issued invoices and credit notes, and optionally a second with your expenses. Bookings use the SKR03 chart of accounts, and you can adjust the revenue and bank accounts.

Your tax advisor imports the files into their DATEV software. Ask them to do a test import before the first real use. Fiscal years that differ from the calendar year are not supported.

In a boarding booking, tap Request deposit and choose a percentage of the total. The app creates a deposit invoice as a draft. When you complete the stay with an invoice, the final invoice deducts the deposit as its own line.

Under More → Expenses. Choose a category such as food & treats, equipment, vehicle, insurance, advertising or office, enter the amount and the VAT included, and add a receipt photo. The monthly overview under Invoices → ⋯ sets your expenses against your income.
