Electronic signature software lets businesses send, sign, and manage legally binding documents online, replacing printed contracts and wet-ink signatures. Platforms range from simple, low-cost tools built for occasional document signing to enterprise-grade systems with audit trails, API integrations, and industry-specific compliance features. Pricing and functionality vary widely, so it's worth matching the tool to how many documents you send and what compliance requirements, like HIPAA or 21 CFR Part 11, apply to your industry.
Electronic signature software lets businesses send, sign, and manage legally binding documents online, covering everything from single-document signing tools to enterprise platforms with audit trails, workflow automation, and API access. In the United States, electronic signatures have been legally valid since 2000 under the ESIGN Act, which gives most electronically signed contracts the same legal standing as a handwritten signature, though certain document types like wills and some court orders are still excluded. Some vendors focus on general business use, while others build specifically for regulated industries like healthcare or finance, adding features such as HIPAA-aligned storage or 21 CFR Part 11 audit trails. Pricing models differ too, ranging from free plans capped at a few documents a month to per-user enterprise contracts. Because the category spans such different use cases, it's worth checking whether a listing is built for occasional personal use or high-volume business workflows before comparing options.

Electronic signature software is a tool that lets people sign documents digitally instead of printing, signing by hand, and scanning them back in. It typically captures a signer's consent along with a timestamp and audit trail, and in most cases produces a document with the same legal standing as a paper signature.
Electronic signature is the broad legal term for any electronic mark or process showing someone agreed to a document, such as typing a name or clicking to sign. A digital signature is a specific technology, using cryptographic keys, that some eSignature platforms use behind the scenes to secure and verify that an electronic signature hasn't been tampered with.
Cost varies a lot depending on document volume, number of users, and whether you need advanced features like API access or industry-specific compliance. Check individual listings for current pricing and plan details rather than assuming a flat rate applies across the category.
Start with your compliance requirements and typical document volume, since these narrow the field quickly. From there, compare signer experience, integrations with tools you already use, and whether you need advanced features like bulk sending or in-person signing before settling on a shortlist.
Basic plans can often be set up and used to send a first document within minutes of creating an account. More involved setups, such as connecting the software to a CRM, building custom templates, or configuring compliance settings for a regulated industry, can take anywhere from a few days to a few weeks depending on complexity.
