Your business will need at least one telephone line to contact clients and suppliers and handle general enquiries. It would be useful to have an email address. A website is a good way to promote your business and the area in which the rides will be taken.
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 out what the best deal for you would be.
You may decide that you need mobile phones as well as land lines, for example for use by Ride Leaders while out on a trek in case of emergency. 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.
