Like any business, a market is going to need clear systems of working that can be implemented by a wide range of skill sets.
It is important that well in advance of your first market there are clear and organised systems in place to deal with all the information you will be required to keep as well as what is needed to deliver a community market.
Not only will you be dealing with your volunteers and traders but will ultimately be responsible for members of the public and everything else that goes into making a market work.
How much time these procedures will take largely depends on the frequency of your markets, number of volunteers you have, and how many people the various tasks get divided up into.
The size and location of your market will have a significant impact on the amount of procedures needed. A market operating out of a village hall will have far less bureaucracy to deal with that one sited in the middle of a street.
