How to Series - Work Schedule

Another article in my 'How to Series'.

I keep a work schedule of every item of work that I get in. I list the date/time, name, description of work, urgent/non urgent, who does the work, (myself or contractor) proofing (I sometimes send work out to a proofreader), time/date complete and comments, time worked, price of job. I keep all this information in an excel spreadsheet and have it set up monthly.
I work for a lot of clients on a weekly basis, so keeping good records of the work helps me to stay organised and know what is going on, it assists with time management, priorising the work and keeping track when I send work out to a contractor. It also gives me the stats at the end of the month to see how many jobs I do on a monthly basis and how much I make on each job that I do. These stats are important to have as you are running a business.
As a client send me in work, i then enter that work on my spreadsheet, giving as much details as is involved, then when the work is complete I finish the entry on the spreadsheet.
I hate doing admin at month end but this is such a help when it comes to doing my invoicing which I do at month end as my clients pay monthly.
If you have any comments on this procedure please share with me, I would love to hear what you do and how you run your VA business.
