What Are E-signatures?

An electronic signature, or e-signature, is a way to sign a document electronically instead of with pen and paper. Rather than printing, signing, scanning, and emailing a file back, the signer applies their signature directly within a digital document and returns it in seconds. For accounting firms, e-signatures replace one of the slowest, most frustrating steps in client work: chasing a physical signature on a tax return, authority form, or agreement.

E-signatures are fast, secure, and in most jurisdictions legally valid, which is why they have become a standard part of how firms collect approvals from clients.

How E-signatures Work

The process is usually simple for both the firm and the client:

  1. The firm uploads or generates the document that needs signing.
  2. It is sent to one or more signers, either through a secure portal or a direct link.
  3. Each signer reviews the document and applies their signature electronically.
  4. The system records an audit trail and stores the completed, signed copy.

Because each step is tracked, the firm always knows the status of a request: who has signed, who is outstanding, and when the document was completed.

Are E-signatures Legally Valid?

In most countries, electronic signatures carry the same legal weight as handwritten ones. Frameworks such as the US ESIGN Act and UETA, the EU’s eIDAS regulation, and similar laws in other regions recognise e-signatures as enforceable, provided the signer intended to sign and a reliable record of the signature is kept. For the vast majority of documents a firm handles, a standard e-signature backed by an audit trail is more than sufficient. For unusually sensitive or regulated documents, it is worth checking the specific requirements in your jurisdiction.

Why E-signatures Matter for Accounting Firms

BenefitWhy it helps
Faster turnaroundClients can sign in a few clicks, so documents come back in hours rather than days.
Less administrationNo printing, scanning, or re-filing. The signed copy is captured automatically.
Clear status trackingThe firm can see exactly who has signed and who still needs a nudge.
Strong audit trailEach signature is recorded with a timestamp, which supports compliance and reduces disputes.
Fewer lost documentsSigned files are stored in one place instead of scattered across inboxes.

Common Uses in a Firm

E-signatures are typically used for tax returns, authorisation and authority forms, ad-hoc agreements, and standalone PDFs that need a client’s approval. Formal engagement letters and proposals usually flow through a dedicated proposal process, where the agreement, scope, and signature are bundled together, rather than being sent as a one-off signature request.

E-signatures in Practice Management Software

When e-signatures are built into the software a firm already uses to manage its work, the benefit compounds. A signature request can be tied to the job it belongs to, the signed document is filed against the right client automatically, and nothing has to be exported to a separate tool and re-imported afterward. That keeps the whole signing process inside the firm’s existing workflow, where it is easy to track and easy to find later.

Conclusion

E-signatures turn signature collection from a paperwork bottleneck into a quick, trackable step. They are fast for clients, legally valid in most jurisdictions, and they leave a clean audit trail behind. For firms that send returns, authority forms, and agreements regularly, e-signatures remove friction and free up time that used to be spent printing, scanning, and chasing.

Frequently asked questions

In most countries, yes. Electronic signatures are recognised as legally valid and enforceable under laws such as the US ESIGN Act and UETA, the EU's eIDAS regulation, and equivalent legislation elsewhere. The key requirements are usually that the signer intended to sign, consented to do business electronically, and that the signed record is kept and can be reproduced. For high-stakes documents, always confirm the specific rules that apply in your jurisdiction.
An electronic signature is a broad term for any electronic mark that shows intent to sign, such as typing your name or clicking to approve. A digital signature is a specific, more technical type that uses encryption to verify the signer's identity and detect any changes made after signing. Most documents firms send for sign-off use e-signatures backed by an audit trail, which is sufficient for the large majority of business and tax documents.
Common examples include tax returns, authorisation and authority forms, ad-hoc agreements, and one-off PDFs that need a client's approval. Formal engagement letters and proposals are usually handled as part of a dedicated proposal process rather than as standalone signature requests.
Reputable e-signature tools capture an audit trail for each request, recording who signed, when, and often details such as the document version and a timestamp. The signed document is then stored so it cannot be misplaced. This record is what makes an e-signature defensible if the agreement is ever questioned.
It depends on the tool. Some firms send signature requests through a secure client portal where the client logs in, while others can send a link the client opens directly. Either way, the goal is to make signing as frictionless as possible so documents come back quickly.
