The client portal access plan
A printable worksheet that records who can see and do what in a client portal, filled in before anyone gets an invitation.
The whole worksheet is on its page, ready to print.
From the worksheet
- Read the four access levels once. Every table below uses them.
- Fill in one people table for each client. The worked example shows a finished one.
- Run the invitation checklist before every invitation.
- Copy the client-facing labels into the portal, with the names filled in.

Portalbender covers the private pages where a firm and its clients, or a seller and a buyer, pass documents back and forth: the portal a firm's clients sign in to, and the room where a buyer reads about a business that is for sale. A bookkeeper collects bank statements there. An attorney sends a draft for signature, and a seller opens three years of profit and loss statements to one buyer while the others wait at an earlier stage.
Firms that keep client files and questions in email start with how to set up a client portal for a small firm, and then the client portal access plan, a worksheet filled in before the first invitation goes out. Sellers, and the brokers who represent them, start with the deal room guide. The setup guide retells a Federal Trade Commission case from 2020, in which a mortgage analytics company's vendor kept scanned loan files on a cloud server with no password.

Common questions
What is a client portal?
A client portal is a private web page for a firm's clients. They sign in to see where their work stands, trade documents, answer the firm's requests, send messages and collect finished work. Accountants, bookkeepers, law practices and consultants use one when clients send and receive documents over months and an email thread can no longer say which file is current. The guide to setting up a client portal for a small firm covers the five jobs a portal does and the three ways to get one.
Is email good enough, or does a firm need a client portal?
Email holds up for a firm with a few clients and nothing sensitive. It strains once clients keep asking where their work stands, or nobody can tell which copy of a file is current. Tax professionals also carry a written duty: federal law requires them to keep a written information security plan, as the Internal Revenue Service reminded them in August 2026. The setup guide links that release.
What should a client portal include?
Five parts cover the work between a firm and a client: status, documents in both directions, requests for what the firm still needs, messages, and deliverables. The setup guide has a table of what each part looks like while it still runs through email. A label on each folder says who can see it, and each person on the client's side has a separate sign-in. The client portal access plan sets a level for each of the five parts, person by person.
