 FormKiQ supports multi-tenancy environments by defining user group(s) and then linking these groups to the different FormKiQ site(s). Each user can be associated with one or more groups, reflecting their role or responsibilities within the platform. These groups, in turn, determine the user's access privileges across different sites within the platform.

+FormKiQ is built using [serverless technology](https://aws.amazon.com/serverless). This means that there are no servers to manage; everything is managed by AWS. All of the AWS services FormKiQ uses have pay-per-usage billing (with only one exception, OpenSearch, an add-on module). You can start using FormKiQ with very little cost.

 In fact, AWS provides a [free tier](https://aws.amazon.com/free) to all AWS accounts. This means that some AWS services you can use for **free**, assuming you are able to stay within the usage limits. Below is the list of services FormKiQ uses and their approximate usage costs, so give you an idea on how much it costs to run FormKiQ. (All costs in USD)

+FormKiQ supports extracting text from a PDF document in two ways that have a different cost structure/features; many PDFs that were created electronically can have their text extracted programatically, without requiring OCR. For documents that are not fully digitized, such as documents that were scanned from paper or came from a photograph, OCR would be required.
