I want to use the ERP system for our business. Could you write Customize? For one of my businesses.
I have absolutely no idea what you are asking - can you be a bit more specific
Manager is an accounting system not an ERP - if you require an ERP, then you need to look elsewhere
Manager is an of-the-shelve accounting application and no bespoke programming will happen for any customer. Within the application you can configure and setup things following the guides. Think it to be similar to any other application be it Excel, Word, they provide a framework in case of Manager for accounting purposes but you have to do setup and content yourself. The tools are there but you will have to build it to your business needs.
