Frequently asked questions
Client portal vs. project management tool?
Portals are client-facing (files, approvals, invoices); PM tools are team-facing. Some client portals include light project tracking.
Can clients pay through the portal?
Many include invoicing/payments or integrate with billing. Confirm the payment options match how you bill.
