Common accounting intake problems

Chasing documents across email threads

You need W-2s, bank statements, prior year returns, and ID verification. Clients send some via email, forget others, and text you a photo of their driver's license.

Sensitive data in insecure channels

Clients email tax documents, share passwords in plain text, and drop Social Security numbers into unencrypted forms. You know it's a compliance risk, but your current workflow does not offer a better option.

Engagement letters signed separately

You send the intake form in one tool, the engagement letter in DocuSign, and the fee schedule in a third. Three touchpoints for the client, three tools for you to manage.

Seasonal bottleneck

January through April, you're onboarding dozens of clients simultaneously. The manual intake process that works for 3 clients per month collapses at 30.

What changes with Portico

One secure link replaces the email chains, separate signature tools, and manual follow-up your firm relies on today.
  • One secure link for everything

    Intake questionnaire, document uploads, engagement letter signature, and retainer payment in a single encrypted flow. Clients complete everything in one session.

  • Bank-grade security, built in

    AES-256 encryption, tamper-proof audit trail, GDPR-ready consent flows. Sensitive documents are handled with the security your profession demands.

  • Conditional forms adapt per client type

    Individual filers see different questions than business entities. New clients get the full intake; returning clients confirm what's changed.

  • Automated follow-up handles the volume

    Item-specific reminders: "You still need to upload your prior year return and sign the engagement letter." Handles 30 clients as easily as 3.

  • Dashboard shows who's done, who's not

    Filter by status, deadline, or client type. See exactly which documents are outstanding without checking email.
