I have a web-based POS developed in MS SQL and ASP .NET and working fine online. it is a multi-client hosted Software-As-A-Service, meaning different companies/clients sign up for account on it and use it to manage their own shops or outlets. it currently requires internet connection to record sales directly online. I am looking for a developer to create the ability for the cashiers to record sales in an offline mode without internet connection and system will synchronize with the online master data when internet is restored.
the most challenging part of this assignment is that i want to have an offline mode that the manager can click on a button in his own online account and it will download it and install the offline mode on each cashier's computers automatically for it to work without the need to be installing a LAN and SQL licenses, SQL servers, etc. for each client. I am getting clients from different cities so i do not want to go from city to city installing servers in each before the offline mode will work. after setting up the client's main account online, the client should be able to do a simple installation of the offline mode. Even if you can use a technology that the client does not have to physically install any program on the cashier's computer all the better.
