The cost of a portal completely relies on what’s built into the portal. Like any other website, it could be less than $5,000 to well over $200,000. A small career portal with less than 20 pages is just a few thousand dollars and is very easy and relatively quick to build. A Distributor portal would add eCommerce, multiple EDI supply chain integrations, shipping and sales tax integrations, most likely an ERP integration, and can cost $50,000 to 200,000, taking 6-12 months to build.
