Billing Model "Recurring" as Annual or Continuous Invoice
With the billing model
+ enabled continuous invoice (annual invoice), a single invoice is created for a longer period (up to 12 months). The customer pays monthly, while the invoice remains valid for the entire period. Ideal for long-term contracts, e.g.:
Maintenance cleaning
Service contracts
Material flat rates
Costs for the use of machines & equipment
