Do you work with Big 4 advisors?
Quick answer
Yes. Tariffi's enterprise engagement structure accommodates co-advisory arrangements where your existing Big 4 tax or trade team owns the workpaper review. A licensed customs broker partner transmits to CBP under their own license per 19 CFR Part 111. The engagement letter accommodates a side arrangement with your advisor.
Detailed Answer
Many enterprise importers already have relationships with Big 4 tax or trade advisory practices. Tariffi's engagement structure is designed to complement, not compete with, these existing relationships.
How the co-advisory structure works:
- Your Big 4 team retains their existing advisory role: workpaper review, tax treatment guidance (FASB ASC 450-30 contingent-recovery recognition), and any broader trade compliance mandates they handle for your organization.
- Tariffi handles data preparation: ES-003 parsing, CAPE eligibility analysis, declaration data formatting, and broker routing.
- The licensed broker partner reviews the prepared data, applies professional judgment, and transmits via ACE under their own ABI filer code per 19 CFR Part 111.
No scope overlap. The engagement letter explicitly delineates which party owns which deliverable. Tariffi does not provide tax advice, trade compliance counsel, or legal opinions. The Big 4 team does not need to learn CAPE data formatting. The broker does not need to duplicate either party's work.
The engagement letter accommodation:
The standard enterprise engagement letter includes a "Co-Advisor" section that:
- Names the advisory firm and describes their scope
- Establishes information-sharing protocols between parties (under NDA)
- Ensures Tariffi's fee structure accounts for the reduced scope (since the advisor handles portions that Tariffi would otherwise own)
- Provides for quarterly coordination calls if the engagement warrants them

What's different about enterprise pricing?
Enterprise importers ($5M+ duty paid) receive custom-priced contingency below the standard 10/15/25% tiers, a co-advisory engagement structure that accommodates existing tax or trade counsel, and a dedicated underwriter. Volume-based fee negotiation starts at the first conversation. Contact enterprise@tariffi.io.
How do you handle procurement diligence?
Tariffi provides a complete diligence package under NDA: broker-partnership regulatory evidence (19 CFR Part 111, CBP Rulings HQ H326926 and H350722), FASB ASC 450-30 contingent-recovery memo template, engagement letter redline, security posture documentation (AES-256, TLS 1.2+, 7-year retention), and reference contacts from comparable engagements.
What about IRC section 482 related-party imports?
Related-party imports under IRC section 482 have additional customs valuation considerations that affect CAPE eligibility. Tariffi's analysis engine flags related-party entries for special handling, and the licensed broker partner applies enhanced review. Enterprise engagements include coordination with your transfer-pricing advisors if needed.
How does the Tariffi broker partnership work?
Tariffi prepares CAPE declaration data from importers' ES-003 files and routes it to your broker portal for review. You remain Filer of Record on every filing under your own ABI filer code. Tariffi never touches CBP servers. You earn a flat per-filing filer integration fee per 19 CFR § 111.36(c) — never a percentage.
