Questions

Which rate tables are included?
The Polish delegation regulation (domestic and per country), the HMRC domestic benchmark scale rates, and the GSA CONUS standard rate. HMRC overseas and GSA non-standard localities aren't bundled.
Does it fetch rates online?
No. The tables ship with the server, each with its source URL and effective date.
Does it pay lodging abroad for Polish trips?
No. The foreign table has no lodging limit, and the answer says so.
