Custom code on Workday Studio: 3-6 months per country, multi-year for the full footprint. General iPaaS like Workato or Boomi: 3-6 months per country, no compounding benefit across countries. Unified API aggregator like Papaya: 1-3 months per country where supported, with coverage gaps for the long tail of local providers.
datascalehr’s context layer: hours per country, because KMod is pre-trained on Workday Global Payroll Connect schemas (DCOD, ExPR, ExPD, APD) and 7,000+ source and target schemas.
