Our editorial review of CSSI

CSSI’s service page includes property case studies. Treat these as examples selected by the provider, not a sample of customer reviews. A case study can help identify the kind of property being discussed, but its projected or reported tax figures do not determine the usable benefit for your building.

Commercial owners should connect access and cost records before comparing timelines. If the project includes another incentive assignment, request its own scope and price so the cost segregation study remains identifiable.

Customer reviews, testimonials and case studies

The source checked here establishes service descriptions, fee guidance and selected case studies. It does not establish a current independently verified star rating or complaint rate. We therefore make no numeric customer-satisfaction claim on this page.

Read the CSSI source discussed here. Check the identity of the business and the service mentioned before relying on a review. A dated comment about another product, location or tax service can answer a different question from the one you are researching.

Stratum is a competing cost segregation provider and publishes this commercial editorial assessment. We have not commissioned a study from CSSI for this article, interviewed its clients or tested its report. We do not assign stars or reproduce a platform rating as our own score. Use the source links and a written proposal to check the points that matter to your property.

What to verify before engaging CSSI

Which parts of the building must be accessible for the walkthrough?
When will the required documentation be considered complete?
Which report revisions, CPA support and additional services are included?

Bring a specific example to the discussion: an improvement invoice, an existing asset entry or a room that cannot be accessed. Ask how that item will appear in the final report and which professional resolves an unanswered question. A useful answer identifies the document, the responsible person and the next step.

Ask your CPA to review a sample asset schedule before you sign. Record whether the engagement includes study corrections, post-delivery technical questions and any separately priced filing work. Client service, report evidence and tax implementation are related responsibilities, but the proposal should say who handles each one.

Compare fit and fee with Stratum

Stratum charges $1 per square foot, with a $2,000 minimum per property. That formula establishes our study fee; it does not establish that Stratum is cheaper than CSSI for every building. Compare the same cost periods, inspection responsibilities and deliverables in both proposals.

Review CSSI pricing and the quote checklist, then use the alternatives guide if your required scope differs. The direct comparison explains the two-provider decision; this editorial review focuses on the evidence behind the service descriptions and customer-feedback sources.
