How is this different from the customer portal?
The customer portal is reached through a signed link you send for a specific job, quote or invoice. Homeowner accounts are a persistent login the customer can return to, which suits repeat domestic customers with service histories.
Is a magic link secure?
The link is sent to the email address on the customer record and is rate-limited to prevent abuse. It is the same mechanism used by many banks and services for low-friction access, and it avoids customers reusing a weak password.
What can the customer actually see?
Their own jobs, quotes, invoices and documents. Access is scoped to that customer, so they never see anything belonging to another of your customers.
Does this cost extra?
No. It is part of the platform, like the customer portal, quote acceptance pages and invoice payment portal.
