Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ADP

  • No pricing is published; every quote is custom and driven by employee count and which services are taken
  • Split into three separate products by company size, RUN for 1 to 49 employees, Workforce Now for 50 and above, and Lyric HCM for enterprise, so growing across a threshold means changing product rather than plan

Stampli

  • No transparent pricing published; quote-based model required
  • Specific pricing for individual modules or add-ons not available on pricing page
  • Cost varies based on invoice volume, complexity, and customization needs
