Sine

Sine manages visitor, contractor, staff and compliance processes for facilities. Sine Core lets organizations tailor visitor check-in, provide electronic entry documents and use branded kiosks. Its activity dashboard tracks expected arrivals, people on site and searchable check-in history. Contractor tools cover onboarding, inductions, permits, certifications and compliance records. The Sine Pro mobile app supports nearby-site check-in through geofencing or QR codes, along with visitor notifications and mobile badge printing. Sine is available on Android, iOS, web and API, and lists integrations such as Microsoft Teams, Slack, Outlook, Entra ID, Eventbrite, Gallagher, Honeywell EBI, Cm3 and webhooks. Plans depend on estimated check-in volume, include unlimited hosts and apply a fair usage policy if usage exceeds the plan level. Small through Large plans have a 30-day free trial, after which Sine contacts the customer with billing information. Workflows is an add-on requiring Sine Core. Sine says it encrypts data in transit, uses AWS infrastructure and complies with GDPR requirements.

Sine brings visitor check-in, contractor records and site activity into one facilities platform. Consider its plan-based check-in volume and required Core plan for Workflows when weighing its fit.

Sine suits organizations managing visitor arrivals alongside contractor onboarding and compliance. Its mobile check-in, host notifications and site activity dashboard may also suit teams that need visibility into who is expected and currently on site.

Sine is a facilities platform for visitor entry, contractor compliance and staff activity across sites. It is best suited to organizations coordinating regular contractor traffic and multiple locations, rather than a single desk that only needs a visitor register. The combination is capable, but paid tiers use custom pricing and scale around check-in volume.

Overview

Sine connects visitor management with contractor onboarding, compliance records and a live view of site activity. Its dashboard surfaces expected arrivals, people currently on site and searchable check-in history, giving facilities teams a practical operational record. Contractor workflows cover inductions, permits, certifications and compliance, so the platform has a broader remit than reception software focused solely on guests.

Key features

Visitor and contractor control

Sine Core supports customized check-in flows, electronic entry documents and branded kiosks. Digital invitations, FastTrack QR, host notifications and roll calls create a more organized arrival process. Visitor photo capture and emergency tools help teams identify and account for people on premises. Contractor onboarding and credential records make it a stronger choice where compliance checks are part of everyday access management.

Mobile operations

The Sine Pro mobile app enables nearby-site check-in with geofencing or QR codes, visitor notifications and mobile badge printing. That is useful for staff and contractors moving between locations, although the app does not replace the broader Core platform for configured workflows and site administration.

Integrations and security

Integrations include Microsoft Teams, Slack, Outlook, Entra ID, Eventbrite, Gallagher, Honeywell EBI, Cm3 and webhooks. Medium adds Entra ID synchronization, SAML single sign-on and an Outlook invitation add-in; Large adds a public API, real-time visitor screening and access-control and SecureBridge options. Sine says it uses AWS infrastructure, encrypts data in transit and performs regular audits and penetration tests. Its plans page states GDPR compliance.

Pricing

Sine is paid software with a 30-day trial and no general free plan. Plans are sized by estimated check-in volume, include unlimited hosts and apply a fair-usage policy when usage exceeds the selected level. Small, Medium and Large start with a 30-day free trial; after it ends, Sine contacts the customer with billing information. Prices for those tiers are custom, so buyers should budget for a sales discussion rather than a published monthly rate.

Plan comparison

Sine Workflows is an add-on and requires a Core plan, so organizations wanting workflow automation cannot select it as a standalone entry point. Enterprise customers can receive account setup, training, hardware and dedicated support; all customers can use Sine's help site.

Platforms

Sine supports Android, iOS, web and API access. That mix covers phone-based check-in, browser administration and integrations or custom connections through the API on qualifying plans.

Who it's for

Sine suits facilities, property and operations teams that manage visitors and contractors together, especially across several sites. It is a good match when inductions, permits, certifications, emergency roll calls and searchable occupancy history matter. A small office seeking only a simple visitor log may find its plan structure and volume-based sizing more than it needs.

Pros and cons

• Pro: Visitor, contractor and staff activity share one operational platform, reducing the need to separate entry records from compliance work.
• Pro: Configurable flows, branded kiosks, QR and geofenced check-in support both fixed reception points and mobile sites.
• Pro: Medium and Large provide meaningful identity, API, screening and access-control expansion paths.
• Con: Small, Medium and Large prices are not published, making comparison and budgeting harder before contacting Sine.
• Con: Check-in-volume sizing and fair-usage rules require careful forecasting for organizations with variable traffic.
• Con: Workflows requires Core, so teams wanting that add-on must commit to the underlying plan.

Alternatives

For vendor insurance and document tracking with a permanent free allowance for up to 25 vendors, consider bcs instead. Choose RealPage Vendor Credentialing when property-manager credentialing is the priority and a no-cost manager plan is useful. Breezeway for Student Housing is the better direction for one-property operations, checklists and cleaning workflows. ComplyFlow fits contractor companies that want free registration and paid worker licence handling. Fyxt is an alternative for property CRM and tenant-payment operations with a free starter route. HqO is another paid option for teams evaluating workplace and property software. ISOPro suits buyers seeking compliance-framework software with custom implementation. NetVendor is an alternative centered on vendor enrollment for property-management companies.

Verdict

Choose Sine when visitor reception, contractor compliance and site visibility need to work together across one or more facilities. Its strongest advantage is the progression from configurable check-in and compliance records to mobile, identity and access integrations. Look elsewhere if you need transparent pricing, a permanent free plan or a narrowly focused visitor log without volume-based plan decisions.
