Concept
Divide the group by transportation and department.
The menus are separated by department. Each department can control a document in one page, you can view the working status by job. You can also open other jobs if the customer uses another transportation medium. For example, if one customer asks for sea freight but needs transport and shipping, you can pass all that data to the other transportation manifest - no need to key all the data in again. Meanwhile you proceed to operate documents, you can receive data from operations to create invoice / payment / debit note / credit note and pass all accout data to account department.
