Overview

See it. Fix it. Trust it — in every country.

Mercans brings truly native, end-to-end global payroll to Workday. HR Blizz™ connects to Workday through the Global Payroll Connect framework across all five GPC features — worker and pay-impacting changes flow out of Workday in real time, and payroll results, payslips, tax documents and processing status flow back in. HR, payroll and finance work from a single source of truth, with no manual transfers and no cross-country reconciliation. And because Mercans owns the whole chain — platform, connector and in-country operations in 160+ countries — coverage is only the starting point: the difference is what happens after the data lands.

What you get

  • See everything

    Every record from Workday is visible in your payroll console the moment it lands — inspect it, download the raw data, trust it. Nothing is dropped in silence.

  • Fix it yourself

    Validation runs on arrival. Format and mapping issues are flagged to you with the detail to correct them at source in Workday — no tickets, no waiting for cut-off.

  • Retro without fear

    Backdated terminations, promotions and late increases recalculate automatically. HR Blizz treats salary as a wage type, so history is never a manual correction.

  • Test like production

    Your Workday QA and sandbox tenants connect to matching Mercans environments, so every release and change is proven in parallel before it touches live pay.

  • An audit trail on every run

    Each run records what was already there beside what just arrived — so every change is traceable. Audit and compliance get evidence, not assurances.

  • One owner, end to end

    Mercans owns the entities in every country, built the platform, wrote the connector and runs the operations. No aggregators, no subcontractors — so data has nowhere to disappear.

The outcomes

FAQ

Frequently asked questions

Which GPC features does Mercans support?

All five — ExPR, ExPD, DCoD, APD and GPH.

How does data move between Workday and Mercans?

Bi-directionally, over a REST, event-driven architecture — data moves as events occur, in one unified flow on every integration.

Can I see what actually arrived from Workday?

Yes. Every record lands in your Mercans payroll console the moment it arrives — inspect it and download the raw data.

How are errors handled?

Data is validated on arrival and flagged for you to correct at source in Workday — before payroll runs, not at cut-off.

How are backdated changes handled?

Automatically. HR Blizz treats salary as a wage type, so prior periods recalculate whatever the effective date.

Can I test Workday releases safely?

Yes. Your QA and sandbox tenants link to matching Mercans environments for true parallel testing, before anything touches live pay.

Who actually runs my payroll in each country?

Mercans. We own the entities, platform, connector and operations — no aggregators or subcontractors in the chain.

How secure is it?

SOC 2 Type II (audited by KPMG), ISO 27001, ISO 27701, ISO 27017 / 27018, EU Binding Corporate Rules, Tier IV data centres in the EU and UAE, and an in-house DPO.

How many countries does it cover?

160+, with Mercans-owned entities in every country.

How long does it take to implement?

Multi-country programmes vary by scope. The connector is pre-built, and linking your tenants for parallel testing de-risks every step to go-live.
