How to choose
If your firm relies on SAP or Oracle, choose DocuSign, which supports over 350 integrations including these specific platforms, rather than signNow which lacks specified integrations.
Avoid Adobe Acrobat Sign if you exceed 150 transactions per user per year, as this is a hard limit; opt for Dropbox Sign which has no transaction limits.
For complex financial documents requiring native PDF editing, select Adobe Acrobat Sign; for standardized templates like NDAs, PandaDoc offers 750+ pre-built options.
If budget is tight, signNow starts at $8/user/mo, but DocuSign Standard at $25/user/mo is justified for firms needing multi-party routing and audit visibility.
Our verdict
For most accounting firms in 2026, DocuSign is the superior choice due to its deep ERP integrations and multi-party routing capabilities, despite its higher price point. Small firms with high volume but low complexity needs should consider Dropbox Sign for its unlimited transaction allowance.
