I charge a monthly fee for my services for Facebook and Twitter account managment and for that the business owner gets:
- Development of a strategy and plan before anything starts;
- Creating posts (the number will vary on the content they have to share and what I work out in the plan, but I usually like to be able to post at least once a day on Facebook and at least 3 times a time on Twitter);
- Monitoring and responding to any comments or posts left by fans and followers;
- Analysis and a report each month to show you how the two networking site are tracking so you can evaluate the job I am doing.
My other services, such as mentoring, I usually charge by the hour as these are usually short, more specific, issues I can help with.
I also offer a comprehensive strategy plan for those who want to get started but manage it themselves, which has a one-off cost.
I guess what I am saying is don’t limit yourself to one type of payment system – match the payment to the type of work.
It might be better if you give us a better understanding of what you are offering.
Hope that helps a little.
