Client portal software

Choosing client portal software without regretting it in six months.

Most comparisons list features. The decisions that actually bite are narrower than that: how data is separated per client, what can be hidden, and whether the portal becomes a second place you have to keep updated.

TL;DR
  • Per-client data separation and field-level hiding are the two features that matter most.
  • A portal that needs separate updating will drift from reality within weeks.
  • If your delivery already runs in Notion, a Notion-based portal avoids a migration entirely.
Good to know
  • Shared passwords are not access control — you cannot revoke one person.
  • View filters are a display convenience, not a permission boundary.
  • Ask what happens to your data when you leave, before you start.

What the software has to do

Per-client data separation

The non-negotiable. Client A must never see Client B's records, and it must be enforced by the system rather than by remembering to set a filter.

Field-level visibility

You will always have data on the same record that clients should not see — cost, margin, internal status. Whole-page permissions are not enough.

Login you can revoke

Per-person accounts, not a shared password. When an engagement ends, access ends without disrupting everyone else.

Your branding

A portal on someone else's domain with someone else's logo undercuts the professionalism you are buying it for.

One source of truth

If the portal is a second place to update things, it will drift. It should read from wherever you already work.

Three ways people solve it

ApproachBest forUpsideTrade-off
All-in-one suitesFirms that want CRM, billing, and portal in one systemEverything integrated; no assembly requiredYou migrate your process into their model, and pay per seat for parts you may not use
Custom buildTeams with engineering capacity and unusual requirementsExactly what you wantMonths of work, then ongoing maintenance and security ownership forever
Notion-based portalTeams already running delivery in NotionKeeps your existing process; no migration; fast to launchRequires your data to live in Notion databases with sane relations

We build the third option, so treat this page accordingly — but the trade-offs above are real, and an all-in-one suite is genuinely the better answer if you want billing and CRM in the same system.

Six questions for any demo

  1. 1.Can it show two clients different rows from the same table without duplicating the table?
  2. 2.Can it hide a single property from clients while your team still sees it?
  3. 3.Can you revoke one person's access without changing anyone else's?
  4. 4.Does it run on your domain with your logo?
  5. 5.When you update the underlying record, does the client view change without a publish step?
  6. 6.What happens to your data if you stop paying?

Already running delivery in Notion?
