A Business desktop Software app and cloud SAAS - repost

This is a project consisting of 1. a desktop software app 2. a cloud app 3. different desktop apps can sync to update a user's cloud account with up to date transactions. This involves inventory management( with ability to use barcode scanner, re-stock alert via sms and email), accounting,customer relationship management (apps can send sms and email),social marketing, invoicing( user can customise invoice size and details,send as email,save in pdf format) and real time business reporting on daily, weekly and monthly basis via sms alerts and email. Different users can sign up to use cloud business app and will be billed on a monthly or annual basis based on their preference. Users can sign up and monitor many branches of their business in real time on the cloud with any mobile device. As the desktop app is used at different branches of an admin, transactions reports of various branches and functions (sales, expenses, inventory etc) are synced real time to the cloud account of the admin. Different security measures will be put in place to ensure store managers cannot alter any data and others. Desktop app and SAAS are different. A serious freelancer is needed for this job.
