Streamline Multi-Party Reviews

CPAs, partners, and review teams can access documents simultaneously with permission controls. Track who reviewed what and when for liability protection.

Simplify Client Document Collection & Organization

Tax season and audit season bring chaos: clients email receipts, invoices, and financial records from multiple addresses. Files get buried in inbox threads, duplicates appear, and you can't track what you've received. Sinosend replaces this with a secure client portal. Send branded request links asking for specific documents (e.g., '2025 Tax Year Receipts'). Clients upload securely. All documents appear in your organized dashboard by client and document type. No more email searching, no more missing receipts.
