Where each one falls short

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

Acumatica

  • Pricing is not published; the vendor directs buyers to a pricing review or an industry calculator instead
  • Cost is driven by transaction volume, data storage and resource levels, so spend rises with business activity rather than staying fixed
  • Charged per application implemented, so adding a module changes the price

Odoo

  • The free plan is limited to one app, so any second module moves the whole account to a paid per user plan
  • Standard runs $13.50 to $16.90 per user per month and Custom $20.40 to $25.50, both quoted with a yearly discount applied
  • Implementation services and custom development are not included in any plan
  • Odoo.sh hosting is required for custom modules and is charged separately from the subscription
  • SMS credits and AI scanning are billed on top of the per user price
