Adobe Sign
Electronic signature solution from Adobe with secure document signing workflows, templates, and audit trails for accounting firms.
Dropbox Sign
Dropbox Sign (formerly HelloSign) is an e-signature platform with a straightforward interface for sending documents for signature, creating reusable templates, and managing signed documents. It provides legally binding signatures compliant with ESIGN and eIDAS regulations, with audit trails for every transaction.
Accounting firms use Dropbox Sign for engagement letters, tax authorizations, and other documents requiring client signatures. It integrates natively with Dropbox for file management, as well as with Google Workspace, Microsoft Office, and other business tools. API access is available for firms that want to embed e-signature functionality into custom workflows.
Dropbox Sign is best suited for firms already using Dropbox for file storage or those wanting a simpler, less expensive alternative to DocuSign. Firms that need advanced features like bulk sending, complex approval routing, or deep CRM integration may find DocuSign or Adobe Sign more capable.
