The contingent workforce tech stack

ENGAGE.
One platform.
The whole program.

ATS, VMS, international EOR portal, 1099 compliance, and program-wide visibility, all in one system. Run your contingent workforce in-house with the same tech HQ Simple uses to run it for our clients.

HQ SIMPLE is the service. ENGAGE is the tech that powers it. You can use either, or both.

What ENGAGE does

Six modules. One contingent workforce platform.

ENGAGE replaces the patchwork most contingent programs run on: an ATS, a VMS, a separate EOR portal, a spreadsheet for 1099 risk, and a reporting tool that doesn't see across the program. One system, one data model, one login.

ATS

Applicant Tracking System

Source, screen, and offer in-house. ENGAGE is a full ATS (careers page, candidate pipeline, structured interview kits, offer generation, e-sign) purpose-built for teams hiring contingent and direct workers side by side.

  • Branded careers page + job listings
  • Pipeline + candidate CRM
  • Structured screening + interview kits
  • Offer generation and e-sign
  • One-click conversion: candidate → 1099 or W-2 EOR
  • Free for HQ Simple clients
Pairs with Sourcing + EOR
VMS

Vendor Management System

Stop paying an MSP 2-4% to manage your staffing suppliers. ENGAGE gives you the same vendor controls procurement teams expect (req routing, rate cards, supplier scorecards, consolidated invoicing) without the layer above.

  • Multi-vendor req routing + distribution rules
  • Published rate cards + tiered approvals
  • Supplier scorecards + diversity reporting
  • Time + expense capture, consolidated invoicing
  • Spend analytics with GL coding
  • SAML SSO, SCIM provisioning, full audit log
Pairs with Rethink your MSP
INTL EOR

International EOR Portal

Country-aware onboarding, payroll, and compliance for every worker outside your home market. The four direct countries we operate in run inside ENGAGE end-to-end; partner countries flow through with the same clean interface.

  • Country-specific onboarding flows + document checklists
  • Multi-currency payroll, FX-transparent
  • Statutory benefits + leave tracking by jurisdiction
  • Right-to-work and visa documentation
  • Pay-stub access in-platform for the worker
  • Full audit trail per country, per worker
Pairs with Employer of Record
1099 OPS

1099 Project + Compliance

Treat 1099s like a real program, not a Rolodex. Project-level engagement tracking, AI-assisted classification scoring on every active contractor, and an audit file that's already compiled when an auditor asks.

  • Engagement-level project + scope tracking
  • AI risk scoring on classification factors
  • ABC, IRS 20-Factor, and Borello assessments
  • 1099-NEC and 1042-S issuance
  • Treaty-aware withholding for international ICs
  • Audit-ready file packet, generated continuously
Pairs with 1099 / IC Compliance
REPORTING

Program-wide Reporting & Visibility

One dashboard for the entire contingent workforce: directly hired, EOR-employed, and supplier-sourced. Spend, headcount, time-to-fill, supplier mix, and compliance posture in views your finance team and program owner can both read.

  • Live spend dashboard with drill-down to engagement
  • Headcount mix: direct, EOR, IC, supplier-sourced
  • Time-to-fill, time-to-onboard, NPS
  • Compliance posture: classification, audit readiness
  • Quarterly export packets for finance and procurement
  • Custom views with role-based access
Underlies every HQ Simple solution
SELF-SERVE

MSP Self-Management

The reason ENGAGE exists as a separate product. Companies that want to run their contingent program without a markup-funded MSP layer can stand up the program directly inside ENGAGE, and call HQ Simple's service team only when they want a human, not a markup.

  • Run your supplier network directly, no middle layer
  • Bring your own MSAs and rate cards
  • Replace MSP reporting with ENGAGE dashboards
  • Optional managed-service add-on by the hour
  • Migrate from an existing MSP with our exit-planning team
  • Recover the 2-4% spend lift back into your budget
