I used to onboard clients with 6 separate emails: Google Form, Notion timeline, Stripe invoice, Calendly, Drive folder, and an email explaining all of it. Half the time something got missed. So I built Handozo - a branded client portal with intake, project timeline, embedded Stripe deposit (inline, no redirect), file uploads, and a checklist. One link. No client login. Free trial, no card needed. See what a client sees: handozo.com/jondoe/brand-identity
