What are
electronic signatures?
Electronic signatures (also called e-signatures or digital signatures) are a digital way of signing documents to show approval or consent, without needing paper, pens, or in-person meetings. They can be created by typing your name, drawing your signature with a mouse or touchscreen, or using a secure signing platform that verifies your identity.
E-signatures are legally binding in many countries, including the US (under the ESIGN Act) and the EU (under eIDAS), as long as they meet certain authentication and record-keeping requirements. They’re commonly used for contracts, quotes, estimates, and approvals, allowing businesses to speed up workflows, reduce administrative costs, and keep a clear, trackable record of every agreement.
With tools like Invoice Fly, electronic signatures make it easy for SMEs and contractors to send documents that clients can sign from any device — helping close deals faster and start projects sooner.
