Erlangtools.com is a free workforce management toolkit for contact center planners. It includes Erlang C, Erlang A, staffing, service level, shrinkage, and occupancy calculators with full support for chat center concurrency, something most online tools still don't handle correctly. Built by a WFM professional who got tired of voice-only calculators in a multichannel world. No signup, no paywall, CSV export included.
