What people use each for

The jobs each tool is most often brought in to do.

RIB CostX

  • A quantity surveying practice that must issue a formatted bill of quantities under NRM or SMM7 and cannot do so from a generic takeoff toolnot Sage Estimating
  • A contractor tendering a job where the client reissues drawings mid-tender, needing revision comparison so only changed areas are remeasurednot Sage Estimating
  • An estimating department moving from paper and Excel to model-based measurement while keeping the same rate library and bill structurenot Sage Estimating
  • A cost consultant producing early-stage elemental cost plans from partial models, then refining the same workbook as design detail arrivesnot Sage Estimating

Where each one falls short

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

RIB CostX

  • Pricing is not published anywhere and is quoted per package and per seat through regional resellers, so two firms of similar size routinely pay materially different rates for the same configuration.
  • It is Windows desktop software with heavy graphics demands; there is no meaningful macOS or browser option, which rules it out for practices standardised on Apple hardware.
  • The learning curve is steep enough that firms typically budget formal training, and an estimator productive in a rival tool takes weeks rather than days to reach the same output here.
  • RIB is owned by Schneider Electric, whose strategic interest is the wider RIB construction cloud, so a buyer choosing CostX today is betting on continued investment in a desktop estimating product inside a group focused elsewhere.
  • BIM takeoff is only as good as the model, and on projects where the model is modelled for coordination rather than measurement the automatic quantities need enough manual checking that the time saving largely disappears.

Answered from the vendors’ own pages

RIB CostX: How much does RIB CostX cost?

RIB does not publish prices. It is quoted per package (Quantify, Core or Complete) and per seat, usually through a regional reseller.

RIB CostX: Is a perpetual licence available?

RIB has historically offered both perpetual and subscription licensing, with subscription now the default push. Ask explicitly, because the perpetual option is not advertised.

RIB CostX: Does it do BIM takeoff or just 2D?

Both. Complete handles IFC and Revit models; Quantify and Core differ in workbook capability rather than measurement.

RIB CostX: Who is it for?

Quantity surveyors and estimators in markets that use bills of quantities: UK, Ireland, Australia, New Zealand, the Middle East and South Africa above all.

RIB CostX: Can we open estimates without a licence?

A free CostX Viewer lets others open and inspect measured drawings and workbooks without a full seat.
