When to keep CSSI on your shortlist
Keep CSSI on the shortlist when you want an engineering-based study or need to discuss cost segregation alongside another specialty tax service. Ask for a sample report for your property type and a clear handoff to your current CPA.
Read the provider’s own description. The public service menu does not establish whether a specific quote includes filings, additional incentive analysis or representation. Confirm those responsibilities in the engagement.
A situation worth comparing
Suppose you own a warehouse with a substantial renovation history and also want to discuss energy-related work. Send each bidder the same supported cost records and ask for separate study and specialty-project scopes.
Choose based on the property analysis, deliverables and named preparer handoff. A broader service menu is useful only when those services fit your actual project.
Compare total cost before switching
CSSI pricing and quote checklist. A software report, an engineering study and a tax advisory engagement buy different work. Compare inspection method, report detail, travel, CPA questions, support and any separately priced Form 3115 or return work.
Request a property-specific study quote and identify the report deliverables, preparer handoff and audit-support terms. Confirm any Form 3115 preparation and return filing separately; a study fee is not an all-inclusive tax engagement.
Ask for a proposal you can compare
- What inspection and engineering documentation will this property receive?
- Which buildings and renovation records are included in the fixed quote?
- Are R&D or energy-related projects separately contracted?
- Who supplies final schedules, answers CPA questions and handles any filing work?
Give each firm the same property address, square footage, closing statement, placed-in-service date, improvement records and existing depreciation schedules. Identify the owner entity, return preparer and deadline. Request a written scope for inspection, engineering analysis, report schedules, support and separately billed implementation. Send sensitive records through the firm’s secure intake process.
Research customer reviews separately
If you are searching for CSSI reviews, check the exact business identity, review date, purchased service and original platform. Ask for relevant references and a redacted sample deliverable. Testimonials do not establish the technical scope of your proposal. This alternatives guide does not verify customer experiences.
