What's the best HRIS for large companies?

It depends on where the company's workforce actually sits. Workday and SAP SuccessFactors lead for large, globally distributed workforces (1,000+ employees across many regions) where implementation budget supports multi-year rollouts. Darwinbox leads for large companies concentrated in India and Southeast Asia. Omni HR leads for large companies headquartered in or operating significantly across APAC that need multi-country compliance and conversational AI without a Workday-scale implementation. There's no single best HRIS for every large company; the right one matches your actual geographic footprint.
