Secure client portals give your clients a branded, professional way to exchange sensitive documents without using insecure email. Clients log in with credentials (typically with multi-factor authentication) to upload tax documents, review draft returns, e-sign engagement letters, and track the status of their work. All files are encrypted during transfer and storage, meeting FTC and IRS requirements for protecting customer information. From your side, staff can request specific documents, send automated reminders, and maintain complete audit trails showing who accessed what information and when. This eliminates the liability of unencrypted emails containing Social Security numbers sitting in client inboxes, provides a professional client experience that differentiates your firm, reduces phone calls about engagement status, and ensures compliance with data protection regulations. Most accounting firms see client portals pay for themselves through reduced administrative time and improved client satisfaction.
