A key one is the type of phone number you use. If you give out your main business number as your mobile phone number, then this suggests to clients or potential clients that you are a small business or a one man band.
If you use a local phone number as your main company number, then it suggests you are a company doing business only in a specific area – eg. you’re a London company or a Birmingham company or a Liverpool company.
However, if you use a non-geographic number such as an 0800 number or an 0845 number, then you are saying that you are a national company – these numbers are not specific to any geographic location other than the UK, so will make your company appear to be a national company. Any company can have them, and they can be pointed to your existing landline or mobile, so can make you appear to be bigger than you actually are.
You can then use a range of extra features to make your business seem even larger, for example the “Press 1 for Sales” (see video) feature inviting your callers to press a number for a different department (these can all point to the same phone), and call queuing, telling your callers they are in a queue and their call will be answered shortly. These are features callers associate with large companies, but are available to all businesses.
