Where each one falls short

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

Buffer

  • The free plan allows 3 connected channels and 10 scheduled posts per channel
  • Essentials at $5 a month covers a single user; team members need the Team plan at $10 a month
  • Approval workflows and custom permissions are Team tier only
  • API access is rationed by plan, from 3,000 monthly requests on free to 15,000 on Team
  • Content ideas are capped at 100 on the free plan

Invoca

  • Entry pricing commonly starts around 1,500 US dollars a month before call minutes, plus a setup and training fee, which prices out agencies and small businesses that only need attribution for a few hundred calls.
  • Telephony minutes and tracking numbers are metered separately from the platform fee, so a seasonal advertising spike produces an invoice nobody forecast.
  • Signal AI, PreSense and quality management are frequently sold as add-on modules rather than included, meaning the demo you were shown may cost noticeably more than the quote you were given.
  • Contracts are annual or multi-year with usage minimums and no month-to-month option, so a campaign strategy that shifts away from phone calls leaves you paying for capacity you no longer use.
  • The product is deep on inbound phone attribution and shallow elsewhere; if your buying journey also involves chat, forms and in-store visits, Invoca covers only one channel and you still need a separate attribution model for the rest.
