The short version

  • Each has a real cost: Document Crunch it is triage, not legal advice, and a company that treats the output as a substitute for counsel on a large or unusual contract is taking a risk the tool never claimed to cover.; 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.
  • They diverge on capability: Document Crunch covers Contract risk analysis, RIB CostX covers 2D drawing takeoff.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Document Crunch

  • It is triage, not legal advice, and a company that treats the output as a substitute for counsel on a large or unusual contract is taking a risk the tool never claimed to cover.
  • Accuracy depends on the document being a recognisable construction contract; heavily bespoke owner agreements and unusual exhibits produce weaker analysis than standard industry forms.
  • The playbook needs configuring to reflect positions your company actually holds, and firms that skip that step get generic risk flags they learn to ignore.
  • It identifies problems it cannot solve; knowing a pay-when-paid clause is punitive does not give a subcontractor the leverage to have it removed.
  • Benefit depends on project staff consulting it during the job rather than only at signature, and that habit change is the part that fails most often.

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

Document Crunch: Does it replace a construction lawyer?

No. It tells you where to spend legal hours and catches the provisions that get missed entirely. Unusual or high-value contracts still need counsel.

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.

Document Crunch: Who gets the most value from it?

The party that did not draft the contract, which most often means subcontractors receiving a different subcontract from every general contractor.

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.

Document Crunch: Is it only useful before signing?

No, and arguably the larger value is during the job, when notice deadlines and change procedures need to be followed by people who never read the contract.

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.
