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

PostHog

  • The free tier covers 1M events, 5K web session recordings and 2.5K mobile recordings per month before usage-based billing starts
  • Accounts without a card on file are limited to 1 project; adding one raises it to 6
  • Data retention is 1 year until a card is added, which extends it to 7 years
  • Support is community-only until the account is on a paid plan
  • Error tracking is capped at 100K exceptions and surveys at 1500 responses per month on the free tier
