Your business will need at least one telephone line to contact suppliers, book DJs and bands, receive customers' bookings (for example, if you hire out the club for private parties) and handle enquiries. You may also decide that you need a fax machine and it's increasingly important to have internet access and at least one email address. A website is a good way to advertise your nightclub and tell people about upcoming events, visiting DJs and so on, although you may just decide to use Facebook, Twitter and Instagram instead.
The telephone company will bill you every month or quarter for the calls you have made, often plus an amount for the line rental for the next quarter.
Many different internet service providers (ISPs) offer internet connections and email accounts. Shop around to find the best deal for the package of services your business requires.
You may decide that you need mobile phones as well as land lines. Again, there are many different deals available offering different options and payment plans to the user.
Various packages and discount structures are available to business users, which can help to reduce telecommunications costs. Contact your telephone company's customer services department for details.
