Secure Portal

My client is a rent-to-own company that works with multiple retailers that rent equipment to people. There are four printed documents that need to be completed in order to finalize and close a contract. My client wants to make this entire process digital by creating an online portal that each retailer can log in to and fill out each document.

See attached word document before bidding.

I've attached an example of a portal for reference. Ignore the red text and drawings.
