I need a system that let company staffs able to log online and to post their expenses online with - date - department - categories - sub categories ( based on the categories) - description, - amount of money, - attachment upload, - approval field (admin/manager will approve this for pending/approved/rejected with name of admin/manager ) - 2nd approval field (same as above but for certain amount of money, admin/manager needed to assign 2nd admin/manager for this 2nd approval). - approved amount (after approved, admin/manager able to enter certain amount of money, or use the full amount that post earlier by staffs.) - accounting status ( accountant able to update this field for pending/paid and with date and accountant name, if admin/manager approved the post) admin - could see and print the report that from databases based on the above fields by filters and by date. - able to see the amount of money for every department that been approved - able to see the amount of money for every department that NOT been approved - able to get auto calculation for total for amount been approved + amount NOT been approved the above are the major thing for this project, minor structure will be explain later.
