How Much Does a Custom B2B Portal Cost?

The cost of building a custom B2B portal can vary significantly.

A relatively focused portal that allows customers to submit requests, upload documents, and track status is very different from a multi-role platform that connects customers, vendors, internal teams, ERP systems, payments, reporting, and complex approval workflows.

That is why there is no meaningful universal answer to:

“How much does a B2B portal cost?”

A better question is:

“What does the portal need to do, who needs to use it, and what business process are we trying to improve?”

Those answers determine the real scope.
