When you start a new business from home, every penny counts. Income is likely to be unpredictable while you get your business established, and you are also likely to be offering your goods and/or services at a bargain introductory price. This pushes many new home business people into saving money by writing their own communications - web-pages, advertisements, blogs, promotional articles and so forth. However, this can be one of the biggest mistakes to make.
From years of proofreading experience, I know that people read what they think they have written, and so find it difficult to pick up the errors in their own writing. Word processor spelling and grammar checks can pick up many errors, but they are not infallible and a set of skilled human eyes are needed to to make sure the writing is accurate.
Errors in writing matter for two reasons. Firstly, they give the impression that the writer is unprofessional - careless, or even uneducated. Writing 'effect' when you mean 'affect',' there' when you mean 'their' and other common errors all give a bad impression, even in the modern world of text-speak. Secondly, stray words often creep into writing that has been altered several times, and the meaning of the text can be mangled as a result.
Even more than proofreading, editing advice can be invaluable. Your meaning may be crystal clear to you, but not to someone with little or no knowledge of your business. Your customers will need to see certain key information quickly if they are not to lose interest and decide to buy elsewhere. As a business person, you are bound to be enthusiastic about your product, and keen to impress upon your potential customers the quality and value of what you provide. An editor can read your text, suggest a better order for the points you want to make, and make sure the key information is immediately obvious. They may also be able to explain things more simply than you have been able to do, and all these factors will help to get you a sale. In addition, as the editor doesn't have your detailed knowledge of your business, they will be able to tell you if there is information they would have liked to see which you have overlooked.
