Where each one falls short

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

Rootstock

  • Every Rootstock user also needs a paid Salesforce platform licence, so the true cost is two subscriptions stacked; third-party estimates put a fully loaded seat around 200 to 500 US dollars per user per month, which is far above the Rootstock line item alone.
  • Rootstock publishes no pricing whatsoever, so budget-setting depends on reseller and analyst figures rather than vendor rates, and there is no public benchmark to test a quote against.
  • Building on Salesforce means inheriting Salesforce governor limits and API constraints, which surface as batch size and data volume ceilings in high-transaction manufacturing that a purpose-built ERP would not hit.
  • Your ERP is now hostage to another vendors commercial decisions: Salesforce list price rises, edition changes or licence policy shifts flow straight into your ERP running cost with no alternative supplier.
  • Implementation is a serious project, commonly quoted in the tens to hundreds of thousands of dollars and measured in months, and the partner pool that genuinely knows both manufacturing and Salesforce-native ERP is small, which lengthens timelines and raises day rates.

SOS Inventory

  • The Companion plan at $69.95 per month is limited to a single location and 1 custom field
  • Serial and lot number tracking, barcoding and unlimited locations require the Plus plan at $139.95 per month
  • Phone support is excluded from the Companion plan
  • Job costing, advanced manufacturing and the customer portal require the Pro plan at $194.95 per month
  • Each plan includes only 2 to 5 users and additional users cost $25 each per month
  • The 2 months free discount requires paying a year up front
