How we make money
NerdBible is an independent comparison site funded by referral fees. When you visit a company through a link on our pages and buy or sign up, that company may pay us a commission. You never pay more because of it.
Commissions do not decide our rankings, scores or reviews. Those come from our own research and a published methodology, and we apply the same standards to every product whether or not it pays us. Not every product in a category is included, and the companies on our lists can change over time.
E-signature software replaces print-scan-email cycles with tracked, legally recognised signing on any device. We compared compliance (eIDAS/ESIGN), templates, CRM integrations and per-envelope pricing.
For sales-led teams that send proposals, quotes and contracts every week, PandaDoc is worth it. It turns document creation, approval, signature and payment into one tracked flow, with compliance coverage strong enough for regulated sectors. That is why we rank it first. Buy the plan that includes the features you will use, budget for any add-ons, and test deliverability and templates before you roll it out.
For businesses that send agreements regularly and want everyone on the team to have access, yes. Unlimited users, unlimited templates, solid audit trails, mobile apps and sensible routing tools add up to strong value, and the security credentials are appropriate for most commercial use.
pdfFiller earns its place at the top of our ranking because it covers the real-world PDF job, finding the right form, filling it, signing it and sending it, more completely than any other editor we list, from any browser and on mobile. Its forms library and template tools are genuinely time saving, and its published security credentials are what you want from a service holding personal paperwork. Go in knowing it is a cloud subscription with an auto-renewing trial: set a reminder, pick the plan that includes the features you need, and it is the editor we would recommend first.
DocHub is the most convenient way for Google Workspace users to edit, sign and send PDFs. It is fast to start, well integrated with Gmail and Drive, and backed by a solid published security record. Treat the free plan as a trial, choose Pro if you send documents for signature regularly, and check the billing period at checkout. For everyday e-signature needs it does exactly what most small teams need.
For a UK small or mid-sized business with several people who send documents, yes, Signable is one of the more sensible choices. The unlimited-user model removes the most annoying cost of e-signature software, UK data hosting and UK support solve real compliance and service problems, and the feature set covers what most offices actually do: templates, reminders, signing order, bulk send and an audit trail that stands up as evidence. It earns its place on our list as the pick for UK SMEs. Its limits are equally clear: volume caps, UK-only advanced signatures and no qualified signatures yet.
For teams that already rely on a professional PDF editor, Foxit is a strong and coherent choice. You get a well-reviewed editor and a signing service that covers templates, web forms, bulk sending, payments and notarisation, with a compliance toolkit that reaches regulated industries. That combination is why we list it as our pick for a PDF suite with signing. It is not the cheapest route for a solo signer, the plan structure needs careful reading, and QES requires a third-party account. Start with the 14-day trial, ideally inside the PDF Editor your team will actually use.
For an enterprise that already runs on Microsoft 365 or Adobe Document Cloud, yes. Acrobat Sign combines the most widely used PDF software with a signing service that plugs into the business systems large organisations depend on, and it carries compliance credentials, including FedRAMP Moderate, that most rivals cannot match. That is why we rank it as our pick for enterprise use. Smaller teams should be more careful: work out which Acrobat plan you actually need, check the transaction limits, and read the cancellation terms before committing to an annual contract.
Scores are not pay-to-play. We compare each provider's compliance documentation, templates and integrations from its own pages, verify pricing and read verified user feedback. Affiliate relationships never change a ranking.
Compliance (35%): audit trail, eIDAS/ESIGN.
Workflow (30%): templates, bulk send, reminders.
Integrations (20%): CRM, storage, API.
Value (15%): envelopes, seats.
Are e-signatures legal?
In the US (ESIGN) and EU (eIDAS), qualified electronic signatures on reputable platforms are widely enforceable for business contracts. Always check regulated industries separately.
What users rate them
Checked October 5, 2026
User ratings show how people who chose to leave a review felt about a company or app. They are useful for spotting patterns, such as repeated complaints about billing, renewals or support, but they are not a measure of how well a product works: happy customers review less often than unhappy ones, some companies invite reviews more actively than others, and a score built on a few dozen reviews can move a lot with a handful more.
Trustpilot rates the company behind a product, usually for all of its products and services, and often reflects buying and billing experiences. Apple App Store ratings cover one iPhone and iPad app in the US store, so they say little about a desktop or web version. An App Store rating is shown only when the app is published by the vendor itself. The two scores come from different groups of reviewers and are not combined here.

We sign up, run real workflows, compare pricing and limits, and score each tool on results, ease of use and value. Affiliate links never change a ranking.
Do these tools replace human teams?
They automate repetitive work: drafting, routing, follow-ups and reporting: but you still set strategy, approve messaging and handle complex cases.
Is my data safe with AI vendors?
Reputable vendors offer SOC 2, GDPR controls and opt-outs for model training. Check each provider's data policy before connecting CRM or customer inboxes.
