Can a single advance invoice be issued for a service provided over several months?

/ Can a single advance invoice be issued for a service provided over several months?

This is possible under certain billing models, but the invoicing method must reflect the contract, the payment terms and the rules on when the tax point arises. For continuous or periodically settled services, the end of the settlement period is key, and receiving an advance payment may bring VAT forward. Before issuing the invoice, it is worth checking the specific schedule of services and payments.
