PEO: often co-employment bundled HR. ASO: à la carte services; you remain employer of record. EOR: legal employer in country when no local entity—common for global hiring.

Often cited: vendor dependency, variable quality, transition/change cost, data/confidentiality risk, and contract ambiguity.

Clarify formation vs annual fees, registered office/secretary/filing scope, split government vs service fees—avoid hidden charges (common advice in guides).

Good practice: distinguish mail drop vs compliance-grade registered office—statutory books, filings, and notices may be required; define scope in the contract.

In many US states (and similar concepts elsewhere), companies must appoint an in-state agent for government notices and service of process—foreign founders often must use a local provider.

Often remote filing is possible in some places, but banking, notarization, and KYC may still require steps on the ground—verify per jurisdiction.
