SIGN.PLUS

SIGN.PLUS is a legally binding electronic signature platform for signing contracts, NDAs, offers and HR documents on web, iOS, Android and via API. Part of Alohi SA, a Swiss software company headquartered in Geneva, it is compliant with eIDAS, ESIGN, UETA, HIPAA and GDPR and is used by individuals and teams across 150+ countries.

The product pairs a drag-and-drop document preparer — signature, initials, date, text and checkbox fields — with reusable templates, bulk sending, in-person signing and automatic reminders. A detailed audit trail, certificate of completion and tamper-evident seal are generated for every signed document, giving the same legal weight as a handwritten signature under eIDAS.

Key benefits:

• eIDAS-qualified electronic signatures legally binding across the EU and EEA
• Reusable templates for contracts, NDAs and HR documents used daily
• Bulk send to hundreds of recipients from a single template with personalised fields
• In-person signing on tablet or phone for client meetings and onboarding
• Audit trail and tamper-evident seal generated automatically for every completed document
• Integrations with Google Drive, Dropbox, OneDrive, Salesforce and webhooks
• Public REST API and SDKs for embedding signing into products and workflows

SIGN.PLUS is operated by Alohi SA, headquartered in Geneva, Switzerland, with servers located in Switzerland and the EU under Swiss FADP, GDPR and eIDAS. ISO 27001 certification, a full DPA and SCCs for any sub-processor transfer are standard on paid plans.

Trusted by 100,000+ businesses worldwide, SIGN.PLUS is the reference choice for teams that want a straightforward, eIDAS-compliant e-signature product backed by Swiss jurisdiction and EU data residency.
