The buyer's problem

Most Workday integrations are still file-based, batch-shipped,
and held together by a vendor's local subcontractors.

If you run payroll in 30+ countries on Workday, you already know the pattern. 20 templates. 20 SFTP folders. 20 different vendors hiding behind one logo. Errors surface days late, after batch runs, after gross-to-net is already locked. Compliance lives in a spreadsheet shared between three people who don't work for the same company.

Latency

Batch windows hide errors until it's expensive to fix them.

PECI-only architectures move data on a schedule. A new hire on Monday is a payroll input on Friday. A termination on Wednesday is a compliance exposure on the 28th.

Subcontracting

Aggregator models put a different liability on the line in each country.

"Global" payroll providers often broker third-party payroll bureaus locally. The contract is one. The accountability isn't. Data crosses three legal entities before it lands in Workday.

Partial certification

Half-stack GPC support means half-stack ROI.

Some providers certify DCoD only. Others ExPR only. Mercans implements all five - because the value of GPC compounds when DCoD feeds APD which feeds the engine which writes back to ExPR which lands in ExPD.

Mercans fixes them all.

Twelve questions. Our answers.

The twelve things that matter most in a Workday GPC integration — and what Mercans delivers on each.

Question	Why it matters	Mercans
Does the company calculating my payroll in-country own a legal entity there, or is a subcontractor calculating it?	Determines who you are actually contracting with. Drives SLA, compliance, and incident accountability.	✓ Owned entity
Is the platform built and operated by the same company that signs my contract?	Determines roadmap velocity and where bugs and features actually get fixed.	✓ Built & operated
Are all five Workday GPC features certified?	Partial certification means the buyer fills the gap with file feeds.	✓ 5 of 5
Are all five features in production with paying customers today?	Certified on paper is not the same as live in production.	✓ Live
Does the integration use REST and event-driven flow, or rely on file batches?	Drives latency between an HR change and its appearance in payroll.	✓ REST · event-driven
SOC 2 Type II — audited by whom, when?	Type II means controls were tested over time, not just designed on paper.	✓ KPMG · 2025
ISO 27701 (Privacy Information Management)?	The privacy-specific extension of ISO 27001. Few payroll providers hold it.	✓ Certified
EU Binding Corporate Rules — approved?	Strongest available basis for intra-group cross-border data transfer.	✓ Approved
What tier are the data centres, and where?	Drives availability, residency, and sovereignty position.	✓ Tier IV · EU + UAE
Is the named DPO function in-house and accountable, or contractually delegated?	Determines responsiveness on DSARs, regulator interaction, and breach.	✓ In-house
Can I add a country without a new vendor onboarding cycle?	Determines time-to-coverage for organisational growth.	✓ Capacity, not onboarding
Is pricing direct, or layered with subcontractor margin?	Determines economics at renewal and at scale.	✓ Direct
