Hire an accountant or a bookkeeping service. Every writing business must keep a record of its day to day financial transactions and even the smallest of transactions add up to big tax deductions over the period of a year. You can’t simply file everything under ‘miscellaneous’ and you can’t spend an hour or so every day taking care of just mundane bookkeeping duties either. Bookkeepers and accountants only charge for the time that they actually spend working for you. Usually they have many clients. If they spend one hour working on your records then you will only be charged for that one hour. You aren’t a bookkeeper or an accountant and you would have likely spent three or four hours doing the same tasks and then with questionable results. Hire an accountant or a bookkeeping service!
Hire a VA (Virtual Assistant). A virtual assistant can save you hours and hours of time on the mundane tasks that are required to run a successful business. A VA can check your email and send only the emails that you need to personally deal with to you. Entrepreneurs get more junk mail than anybody! A good VA can also act as a travel agent and make airline and hotel reservations for you.
Subcontract assignments to other writers. This bears some explaining. When you are starting out then obviously you are going to be doing all of your own writing. But as your business expands, then consider assigning some or all of larger or frequent projects to subcontractors. They will return their drafts directly to you for finalization and client approval. You will pay them a portion of client fees. Of course, if your business gets really big then you can hire writers. But subcontracting is great for flexibility and growth.
