Your business will need at least one telephone line to contact customers and suppliers and to handle general enquiries. It's important to have internet access and an email address. A website is an excellent way to advertise your business - you might sell goods like ready made (or even bespoke) frames and posters online.
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 - and to make sure that you're getting the best deal they offer.
