Turnaround times depend on a number of factors, most specifically which products or companies you are working with. We can only speak to FBS Products’ process for Flexmls IDX.
Our SmartFrame and WordPress Plugin solutions can be activated within one business day, subject to any MLS approvals. Activation is only access, however, and you will still need to install the product on your website. Depending on your level of capability, the complexity of the implementation you want, and whether or not you are working with a developer, that could take anywhere from a few minutes to a few months.
3rd party products have their own processes and you should contact them directly to learn more about their turnaround times.
